How Do I Choose the Best Business Desktop Computer?

A business computer is a computer designed for business applications. Contains two basic types of business desktops and business notebooks. In fact, the invention of the computer was originally designed for commercial computing. Later, individual users also put forward the requirements of electronic computing, and then there were widespread computer applications. Although they are all computers, from design concept to software configuration, including after-sales service, they are working towards different goals.

Chinese name: Business computer
Object: Computers designed for business applications

basic type: Business desktops and laptops
Application trends: Communication and computing are working together

Basic classification of business computers

Business computers also have different classifications for target consumers

The first category: commercial enterprise scale, divided into: personal business computers, small and medium business computers, large business computer

Lenovo 11-inch ultra-thin business notes The second category: industry, divided into: manufacturing, government, military, education, finance, media, etc.

Business computer application trends

1. Communication and computing increasingly work together

Increasingly, communication and computing work together, enabling users to connect with colleagues, friends, and the world, whether at work or at home.

Always online

Business computer The widespread application of the Internet and wireless technology has nurtured a world of "permanent connection, always online". Users don't have to wait for the computer to "start up" to view their email, schedule, or stock securities.

3. Digital instead of analog

All types of media are gradually replacing analog with digital. Music, photos, television, home movies and even news have become digital. Users are also free to store, process and exchange digital media.

4. Global Organization

The emergence of global connections has produced truly global organizations, and most companies are struggling to improve global collaboration and work to reconcile linguistic and cultural differences.

5. Labor decentralization

Labor decentralization is expanding labor resources, improving production efficiency, and bringing producers and consumers closer together. This decentralization poses challenges to communications infrastructure, security, and manageability.

6. Knowledge workers

The concept of knowledge workers includes more and more employees, from workers on the production line to sales staff to senior managers: information processing technology has changed from behind-the-scenes activities that are used only by a few people, to a fused person to each employee The key at work.

7. Computer ease of use

Making computers easier to operate will be the dominant factor in technological progress. For business users, the high complexity of personal computers hinders further productivity improvements; for individual users, most people still cannot fully grasp their systems, and the benefits of technology are often manipulated Difficulties in equipment weakened.

8. Green environmental protection

For a long time, major PC manufacturers have been actively promoting their different green computers. Especially in the commercial field, the promotion efforts have been increased. However, it cannot be overlooked that after entering 2009, with the gradual expansion of the scope of the global financial turmoil, many companies did not catch green computers when purchasing. In the face of this situation, only by transforming the "green" concept into a "saving money" concept can we better attract business users to pay! So far, whether it is a commercial desktop or a business notebook, they have done a pretty good job in this regard. Because of the participation of Intel, an industry leader, the processor market has been making great strides from 65-nanometer manufacturing processes to 45-nanometer advanced processes since 2008.

A series of problems such as large heat generation, unsatisfactory power consumption control, and inability to increase the main frequency have been well resolved with the emergence of new processes. Take the Q8200 quad-core processor, the flagship of the Intel camp, although its main frequency is reduced to 2.33GHz. However, due to the use of the latest 45nm process technology, its performance is still comparable to the Q6600 processor clocked at 2.4GHz. More importantly, the Q8200 processor consumes less power, generates less heat, and saves power. At the same time, mid- to low-end dual-core processors are also actively promoting 445-nanometer process technology.

Both the E5200 on the desktop platform and the T4200 on the mobile platform are typical representatives of low-power processors with 45-nanometer process technology. According to the corresponding test data, a desktop or notebook computer using a 45nm process technology processor can reduce energy consumption by 25% to 35% compared to a product using a 65nm process technology platform. The monthly electricity bill alone can save about 1/3.

What is certain is that low power consumption will become the main trend of future development in the commercial field, and the concept of energy saving and power saving will also bring more economic benefits for enterprise users!

9. Performance is king

Speaking of changes in business PCs (including business desktops and business notebooks) in recent years, the most obvious trend is that performance is king. Because with the increasing demand for enterprise applications, it must be a high-performance business notebook or desktop computer to win the hearts of the people. The era of building commercial desktops with low-end processors and CRT displays has passed, and commercial PCs are moving towards high performance.

For example, Intel recently launched a latest Core i7 processor, which is an epoch-making product with 45nm manufacturing process and Nehalem architecture. The Core i7 is recognized as an "technical miracle" by the industry. The processor won 117 points in the SPECint_base_rate2006 test (that is, tests the processor speed by simulating a certain number of tasks), setting a new world record. This is also the first processor ever to score more than 100 points.

In terms of notebooks, the latest Intel Centrino 2 processor technology uses the Intel Core 2 dual-core processor (Penryn) based on the industry-leading Intel 45 nanometer process technology. This environmentally-friendly processor is not only faster, lower power consumption, It's more energy efficient, and it also allows business laptops to get rid of their previous huge and awkward shapes and become thin and stylish.

Business computer related components

1. The " software part " includes: operating system, application software, etc.

2. The " hardware part " includes: chassis (power supply, hard disk, disk memory, motherboard, CPU-Central Processing Unit, optical drive, sound card, network card, graphics card) display, keyboard, mouse, etc. (also can be equipped with speakers, printer, etc. ).

Introduction of each component

Hardware system:

The computer's hardware system consists of an input device, a host, and an output device. External information is input to the host via the input device, analyzed, processed, and processed by the host, and then output via the output device.

Input and output devices:

Computers can only recognize binary digital electrical signals, and people are accustomed to receiving graphic and audiovisual signals. Input and output devices play the role of signal conversion and transmission.

Use the keyboard to enter text, use the microphone to enter sound, and use digital cameras, scanners, and camcorders to enter images.

Common output devices are monitors, printers, system speakers, and speakers.

Motherboard:

The motherboard is also called a motherboard, which is a rectangular circuit board installed in the chassis of the host computer, on which the main circuit system of the computer is installed. The type and grade of the motherboard determine the type and grade of the entire microcomputer system. The performance of the motherboard affects the performance of the entire microcomputer system.

A control chipset (commonly referred to as the northbridge and southbridge of the motherboard), a BIOS chip and various input and output interfaces, a keyboard and panel control switch interface, an indicator connector, an expansion slot, and a DC power supply connector are installed on the motherboard. Plug-in and other components.

The CPU and memory module are plugged into the corresponding slots (sockets) of the motherboard, and hardware such as drives and power supplies are connected to the motherboard.

The interface expansion slots on the motherboard are used to insert various interface cards, which expand the functions of the computer. Common interface cards are display cards, sound cards, network cards, and so on.

CPU :

The CPU (Central Processing Unit) is the core of the computer. The computer's ability and speed to process data mainly depends on the CPU.

The bit length and the main frequency are usually used to evaluate the CPU's ability and speed. For example, the PII300 CPU can process 32-bit binary data, and the main frequency is 300 MHz.

System bus:

The system bus is the information path to the expansion slot.

The PCI-E and PCI buses are common system buses for PCs, and there are corresponding ISA and PCI slots on the motherboard.

Input and output interface:

The I / O interface is referred to as the interface connecting the motherboard to the input and output devices. The serial port, parallel port, keyboard interface, PS / 2 interface, USB, HDMI, and other internal hard disk and floppy drive interfaces on the rear of the host are all input and output interfaces.

Serial communication interface:

Abbreviated as serial port, it is a standard interface for computers and other devices to transmit information. The computer has at least two serial ports COM1 and COM2.

Parallel communication interface:

Abbreviated as parallel port, it is a standard interface for computers and other devices to transmit information. This interface transmits 8 data bits in parallel at the same time. The parallel port data transmission speed is faster than the serial port, but the transmission distance is shorter.

The parallel port uses a 25-hole D-shaped connector, which is often used to connect a printer.

EIDE interface:

Also called extended IDE interface, an interface for connecting EIDE devices on the motherboard. Common EIDE devices are hard drives and optical drives. Newer interface standards are Ultra DMA / 33 and Ultra DMA / 66.

AGP :

That is, the "accelerated graphics port" is a graphics card interface standard proposed by Intel Corporation in July 1996. It is connected to the AGP graphics card through the AGP slot on the motherboard. The transmission speed of the PCI bus can only reach 132MB / s, while the AGP port can reach 528MB / s, the transmission speed is four times the former.

AGP technology has greatly improved the performance of graphic displays (especially 3D graphics), and made PCs take a big step forward in graphics processing technology.

Optical drive:

A device that reads disc information. It is an indispensable hardware configuration for multimedia computers.

The optical disc has a large storage capacity, is cheap, and has a long storage time, and is suitable for storing a large amount of data, such as sound, images, animations, video information, movies, and other multimedia information.

There are three types of optical disc drives: CD-ROM, CD-R, and MO. CD-ROM is a read-only optical disc drive; CD-R can only be written once and cannot be rewritten later; MO is a writable and readable optical disc drive.

Internal memory:

Abbreviated as memory, a semiconductor chip used to store information to be currently processed and commonly used information. Small capacity, but fast access.

Memory includes RAM, ROM and Cache.

RAM :

RAM (Random Access Memory) is the computer's main memory, and people are used to calling RAM as memory. The biggest feature of RAM is that data will be lost when the power is turned off or powered off.

A computer with larger memory can process more information at the same time.

Use the refresh time to evaluate the performance of the RAM. The unit is ns (nanoseconds). The smaller the refresh time, the faster the access speed.

586 computer commonly used RAM has EDO RAM and SDRAM. The memory chip is installed on a finger-shaped strip-shaped circuit board, which is called a memory module. The memory module is installed in the memory module slot on the motherboard.

There are 30-line, 72-line, and 168-line connections between the memory module and the motherboard.

SDRAM memory modules with 168 lines, a refresh time of 10ns, and a capacity of 32M (or 64M) are commonly installed.

Cache :

Cache (cache memory) is a small but high-speed memory located between the CPU and main memory.

Because the speed of the CPU is much higher than the main memory, the CPU directly waits for a certain period of time to access data directly from the memory. The Cache holds a part of the data that the CPU has just used or recycled. When the CPU uses the part of the data again, it can be accessed from the Cache Call directly, which reduces the waiting time of the CPU and improves the efficiency of the system.

Cache is divided into primary cache (L1 Cache) and secondary cache (L2 Cache). L1 Cache is integrated in the CPU. L2 Cache is generally soldered to the motherboard. Common motherboards are soldered with 256KB or 512KB L2 Cache.

ROM :

ROM (Read-Only Memory) is a semiconductor chip that stores computer instructions and data. However, data can only be read from it, but not written. ROM data will not be lost after shutdown or power failure.

The manufacturer stores some important information and programs that are not allowed to be changed by the user, such as the BIOS programs stored in the motherboard and graphics card ROM.

BIOS :

The BIOS is a program, which is the basic input and output system of a microcomputer. The main function of the BIOS program is to manage the hardware of the computer.

The BIOS program is the first program that runs when the computer is turned on. After booting, the BIOS program first detects the hardware, initializes the system, then starts the drive, reads in the operating system boot record, passes control of the system to the disk boot record, and the boot record completes the system startup. When the computer is running, the BIOS also cooperates with the operating system and software to operate the hardware.

The BIOS program is stored in the ROM BIOS chip on the motherboard. Currently, most of the 586 motherboards use Flash ROM to store BIOS programs. The programs (data) in Flash ROM can be updated by running the programs.

CMOS :

CMOS is a readable and writable RAM chip on the motherboard, which is used to save the current system hardware configuration information and certain parameters set by the user. The CMOS RAM is powered by the battery on the motherboard, and the information will not be lost even if the system is powered off. To set and update various parameters in CMOS, you need to run a special setup program. When you turn on the computer, you can enter the BIOS setup program through specific keys (generally the Del key) to set the CMOS. CMOS settings are also commonly called BIOS settings.

graphics card:

Also known as a display adapter card, is an interface card that connects the host to the display. Its function is to convert the output information of the host into information such as characters, graphics, and colors, and transfer it to the display for display.

The graphics card is inserted into the ISA, PCI, AGP expansion slot of the motherboard, and the ISA graphics card has been basically eliminated.

Sound card:

An interface card used in multimedia computers to process sound.

The sound card can convert the voice, music and other sounds from the microphone, radio cassette recorder, laser recorder and other equipment into digital signals for computer processing, and save them in the form of files, and can also restore the digital signals into real sound output. The connector on the rear of the sound card protrudes from the back of the chassis, and there are connectors on the top for connecting microphones, speakers, joysticks, and MIDI devices.

Video capture card:

An interface card for capturing dynamic or still video images input from TV antennas, video recorders, video players, etc., is an important tool for multimedia production. Advanced video capture cards can also MPEG-compress while capturing images to make VCDs.

DVD :

Digital versatile disc. A DVD drive is a device that reads DVD discs. The DVD disc has a capacity of 4.7GB, which is equivalent to seven times that of a CD-ROM disc. It can store 133 minutes of movies and contains seven Dolby digital surround sound tracks. DVD discs can be divided into: DVD-ROM, DVD-R (write-once), DVD-RAM (write-once), and DVD-RW (read and rewrite).

Most DVD drives use EIDE interfaces, which can be connected to IDEas, SATA or SICI interfaces like CD-ROM drives.

Business computer difference

1. Stability and security:

Commercial models pursue high stability, and their adaptability is better than home machines under the same conditions. The average trouble-free working time is more than 5000 hours, and some are as high as more than 20,000 hours. In business environment, security is also a consideration for business machines. Most business opportunities encrypt and protect data in software and even hardware to prevent human Destroy and lose data. Household machines are generally used in home environments, and the continuous use time will not be very long, and the working environment is relatively better than commercial machines, so the stability of home machines in long-term work does not have to be as demanding as commercial machines. Commercial computers on the market mostly use Intel Core 2 vPro processing technology to improve work efficiency while reducing costs. Intel & reg; vPro technology has industry-leading multicore performance & sup1; and built-in security and manageability, specifically designed to minimize downtime and maintain high efficiency as always.

Commercial PCs also have special requirements in terms of security. The relatively open nature of the business environment can easily cause data security issues. Therefore, commercial PCs with security requirements will encrypt and protect data in software and even hardware to prevent human damage and damage. Missing data. Matching the corresponding security solutions is a major feature of commercial PCs, but due to cost constraints, the corresponding security solutions are basically optional, and users who need it can choose to buy it. Home users use it in a relatively closed environment, and the security requirements are not so high, so there is generally no special design in this regard.

2, multimedia functions:

The multimedia functions of commercial models are generally not strong. Some commercial machines are very targeted in design. They only highlight the enhancement of functions suitable for certain applications. They do not require all features to be comprehensive. This is mainly reflected in graphics cards, sound cards, and speakers. In the standard configuration of multimedia equipment, commercial machines are rarely fully equipped. The perspective of the design of the home machine is for the convenience of home users. It has been comprehensive in multimedia. The function has covered all aspects of learning, entertainment, and office. The choice of accessories is becoming more and more complete. The functions implemented are more diverse. It has developed towards the direction of home appliances, and there is a tendency to integrate and replace home appliances.

3.Extensibility and appearance:

Commercial machines should be used in a variety of commercial office environments. In terms of appearance, they are designed in accordance with serious and generous design concepts. Most of the colors of the chassis are white or gray. In order to add functions and external office equipment in the future, the chassis and motherboard of the commercial machine are standard full-size, and the external ports are complete. The ability to upgrade and expand is generally better than that of the home machine, which is convenient for future batch maintenance and repair. repair. Home appliances are sold to home users, so they are both beautiful and personalized in appearance design. The chassis styles are diverse and colorful, and the colors are colorful. The choice of motherboards is tailored to the chassis. Most motherboards are small. Board design, reserved space and slots are less than commercial machines, home machine function design is very comprehensive, general users do not have to consider the issue of future upgrades and expansion.

4. Equipped with accessories: Brand PCs generally come with corresponding software and accessories. Home products and commercial products also differ greatly in this respect. Home products usually come with operating system, audio and video, anti-virus software, and communication and maintenance software developed by some manufacturers. Commercial PCs are usually accompanied by commercial application software developed by manufacturers to implement practical functions such as installation, management, maintenance, and security for commercial purposes. Specific practical functions are mostly network interpretation, software distribution, file transfer, and network control. , Security, and more.

5. Pay more attention to practicality, less attention to appearance

Home: On the one hand, home users should consider whether the appearance does not match the home environment, and on the other hand, they must also consider the entertainment performance of the computer, because many home users like to use their computers to watch DVD movies and play Games, etc., so home appliances pay more attention to the appearance and configuration of entertainment performance issues, most of them are equipped with a 17-inch flat screen or 15-inch or more LCD display, some high-end also equipped with a DVD drive and 6-in-1 or 7 All-in-one card reader.

Commercial: Since commercial brand machines are mainly for business users, they are generally only used in the office, Internet, typing or design industries, so they generally don't pay much attention to issues such as appearance and fashion, and fashion. Its practicality and stability. For example, IBM's commercial brand machines are almost all black, and the black ones are really not very good-looking, let alone fashionable, and Inspur's commercial brand machines are mainly black and very "solemn". See how it looks Many people may not like it. In terms of configuration, commercial brand machines are rarely equipped with a DVD drive, and although some are priced at six or seven thousand yuan, they are still equipped with a 15-inch ordinary display. Compared with the configuration, the display looks very old-fashioned. Of course, there are also some commercial branded machines with very trendy designs. For example, some of Acer's commercial branded machines are beautifully designed. However, such commercial branded machines occupy only a relatively small part of the market. However, with the overall improvement of the appearance of notebooks, business notebooks have been presented with a concise and prominent style design. This is particularly evident in the new generation of business notebooks from brands such as HP and DELL!

6. Focus on overall management convenience and ease of use

Home use: Home users usually only have one computer, and only individual home users have two or three computers. Therefore, home users' computers are only for single-machine management and are not complicated. Business users are different. Even small and medium-sized enterprises have several computers. Generally, a company has more than ten computers, and a larger company has dozens or even hundreds of computers (of course, it can also be solved by using a server. Solution), and each is not an isolated device, but a LAN connected to each other, which is a lot more complicated to manage.

Commercial: From the beginning of design, commercial brand machines have focused on how to implement more convenient management of the product under the LAN of multiple computers in the enterprise, and how to make it easier to maintain and use. For example, Inspur Computer Yingzheng 3200 realizes the features of driver one-to-many, high compatibility and time stability. That is, the backward compatibility of the driver is realized in different versions of the PC products, and the upgrade of the driver can be controlled to about 12 months. One driver can support different versions of the same model chip, and the driver of the new chip will support the previous chip, which greatly reduces the workload of system upgrade and facilitates the management of the computer.

7. Provide targeted solutions to related industries

Home: Home brand machines are generally targeted at individuals or home users, and generally have no special needs in use.

Commercial: Business users are different. In some specific industries, they need a holistic solution to help them improve their work efficiency. To this end, some manufacturers have launched special programs developed for specific industries. The brand solution of the overall solution, such as Great Wall Junjie 4000 (4324P) for the education industry, provides a set of high-efficiency Great Wall multimedia electronic classroom teaching systems, and is fully compatible with the mainstream multimedia electronic classroom systems in the market, ensuring software and hardware Compatible and stable and efficient; Lenovo's Qitian computer is also a computer tailored for the education industry. It can set up a computer to complete the control of the entire network, install a unified teaching environment, and use an integrated chassis to achieve the machine's protection. Founder and Lenovo both have special tax control commercial computers specially developed for the "Golden Tax Project". All of its components have been tested for tax control, ensuring the machine's compatibility, stability and safety in anti-counterfeiting tax control applications. Sex.

8. Pay more attention to security

Home: For individuals or home users, data is not very important, and the relationship is not very important. General protection measures can basically be solved.

Commercial: But for enterprise users, the importance of data is very great. Once the data is acquired by someone with ulterior motives or is damaged by a virus, the loss may be very large. Therefore, business users pay more attention to data security. To this end, some commercial branded machines have also added solutions to data security protection. For example, the Inspur Yingzheng series has a series of security precautions to help users eliminate all potential security risks. Among them, the USB encryption key with 1024-bit encryption level can implement file encryption and email encryption. The internal and external network isolation system can effectively prevent various intrusions and damages from the network. The simple and easy-to-use disaster recovery function can make backups very convenient Hard disk system for full disk recovery, safe and practical. Commercial machines will also be pre-installed with some hardware protection software and hardware to prevent accidental data loss. However, the loading of many security software and the use of security technology have made it difficult to operate business notebooks to a certain extent. For newcomers, it is not easy to enjoy high-end business notebooks!

It is undeniable that the biggest difference between commercial PCs and home PCs was stability. If the mean time between failures (MTBF) of home PCs can reach 300,000 hours, the mean time between failures of commercial PCs can reach more than 1.2 million hours. The direct value of the improvement of MTBF to customers is the decline in the product failure rate, which increases the MTBF from 300,000 hours to 1.2 million hours, which means that the failure rate is reduced by 75%, and the company's later investment can be more economical. In addition, security technology is a major feature that commercial PCs are significantly better than home PCs. Such as the USB key possessed by commercial desktops, and the fingerprint recognition possessed by commercial notebooks, were once the main selling points for the commercial field to survive and at the same time attract customers.

9, after-sales service and technical support ^[1]

For a business organization, raising one more person has to bear an additional cost, so I hope that computer manufacturers can have perfect, fast and effective after-sales service and technical support capabilities, which can reduce the maintenance and maintenance personnel in the organization. This reduces operating costs. Dell took this seriously and provided on-site services ranging from one to three years for its Latitude and Insprion series computers, thus taking away a lot of market share from IBM and Compaq.

10, component commonality between models ^[1]

A business organization (especially a larger business organization) often has different computers purchased at different times. If the components of these computers can be used universally, it can save a lot of purchase costs, for example: several computers can share an optical drive, Or: When a computer needs a long battery life to go out and use, you can take out the batteries of other similar machines to use. This helps businesses get the right solution for them at the lowest cost.

11. Flexible and customizable solutions ^[1]

Larger commercial organizations usually have a complete internal network. At this time, some components such as floppy drives, CD-ROMs, and DVDs that ordinary users need are unnecessary for them. Therefore, in order to meet their own needs, commercial organizations often require notebooks. Computer manufacturers can provide customized products according to the requirements of commercial organizations themselves, reducing the original configuration or adding some special equipment, which also promotes the modularization of computers.

Business Computer Selection Guide

Daily performance of business computer

1) Stability

Stability is the first factor in purchasing a business computer. The stability of a computer is mainly manifested in two aspects: one is mutual compatibility between hardware; the other is compatibility between hardware and software. With the continuous improvement of the operating system, compatibility between hardware and software has become quite mature. That hardware compatibility has become the key to stability.

2) Security

Nowadays, commercial computers have been fully exposed to various possible threats. Trojan horse invasion, virus infection, system crash, loss of critical data, etc. may occur at any time. This is a disaster for both the business and the government.

3) Manageability

Manageability is a general consideration for business computer users, and it is also a major concern for manufacturers.

4) Applicability

The connection between computer applications and daily work is getting closer and closer, and many industries have special characteristics, so whether or not to provide targeted solutions to industry user application characteristics is also a factor that needs to be considered.

Business computer services

No matter how much you emphasize the importance of after-sales technical support and service. Especially for small and medium-sized enterprises, their own technical strength is weak, and they rely heavily on the technical support and services provided by manufacturers. The ability to respond quickly and effectively to user issues is an important criterion for measuring service levels. In the field of domestic computer, no matter the professionalism and availability of services, Lenovo is the best service. Complete and effective product after-sales service and technical support system, providing on-site services for enterprise users and individual users, including hardware failure recovery, spare parts supply and technical support. Perfect after-sales service and perfect product quality complement each other, providing the best choice for business users.

Business computer return on investment

The costs incurred during the operation of the computer system include direct costs and hidden costs.

Direct costs mainly include the costs of system management and maintenance, and daily electricity costs. Hidden costs are intangible losses caused by system failure that delays normal work, delays business progress, and delays in delivery time. If the purchase is not made properly, the hidden costs incurred during use may far exceed the purchase cost of the computer itself. The daily management and maintenance costs, hidden costs are closely related to the stability and safety of the aforementioned products, and the service level of the manufacturer.

When purchasing high-end business computers, enterprises must consider their own needs in terms of security, energy saving, easy management and performance.

Security: For enterprise users, the security of high-end business computers includes the physical security of the computer hardware itself, the authentication security of PCs used by enterprise users, and the data security of PCs. Incidents of computer hardware theft often occur in many enterprises, such as the removal of hard disks, etc., causing not only the loss of performance of computer accessories, but also the more important data loss; internal companies often also have computers logged in by others , It may lead to system chaos or poisoning, or it may be important to steal important confidential files; more importantly, the spread of viruses, hacking and even human misuse will cause serious computer security threats. These pose challenges to the security of high-end business PCs. Enterprises are required to select high-end commercial PCs that provide solutions to various security problems in the market according to their own security situation.

Energy saving: In contrast, the average use time of business desktops is longer than that of home computers, so it has a greater significance for energy saving and consumption reduction of business desktops. The main accessory for energy conservation and consumption reduction in a PC is the CPU. The Q8200 quad-core processor of Intel Core 2 uses the latest 45-nanometer process technology. In the full-load tests of CPUs such as Cinbench and EVEREST, the Q8200 consumes 66W and 76W lower than the Q6600, respectively, and is lower than the 3GHz Q6850. Above 100W. The Intel Core 2 Q8200 quad-core processor consumes less power, generates less heat, and saves power, helping businesses save money.

Easy to manage: More than 50% of the work of IT maintenance staff in the enterprise is dealing with "problems" caused by employee misoperation or unfamiliar with the computer. In order to improve work efficiency, business PCs in enterprises should seek breakthroughs in "easy management" so that IT maintenance personnel can quickly and easily help employees solve problems using computers. In contrast, vPro vPro technology provided by Intel is a good solution. vPro vPro technology enables IT maintenance personnel to complete the system upgrade and fill in leaks, kill viruses, asset statistics, and even remotely restore the operating system even when the PC system is completely paralyzed through remote management functions. .

High performance: Enterprise application requirements are constantly increasing, which requires commercial PCs to have high performance characteristics, which also requires commodity PCs to be equipped with faster processors. The industry's processor technology is changing with each passing day. For example, Intel introduced a latest Core i7 processor with a 45nm manufacturing process and a Nehalem architecture. It won the SPECint_base_rate2006 test (that is, tests the processor speed by simulating a certain number of tasks). 117 points, known as the "technical miracle" recognized by the industry.

Business computer market

The statistical report of the Chinese PC market from 2008 to 2009 Q1, especially some data on commercial PCs, which revealed some new trends that deserve the attention of commentators.

Feature one: In 2009 , the sales volume of the Chinese notebook market surpassed the desktop for the first time.

Regardless of whether it is commercial or home, the sales volume of the notebook market in 2008 has grown significantly. From the data provided by the "2009 China Computer Industry Research and Consulting Report", the proportion of desktop and notebook market sales has changed from 7: 3 in early 2008. For 5.5: 4.5, this ratio will definitely be reversed by 2009.

In fact, in economically developed regions such as North America and Europe, notebook shipments exceeded desktop shipments as early as 2004 and 2005. The Asia-Pacific region is also regarded as the engine of future PC growth. In 2008, the biggest factor driving notebook popularity was nothing more than continued guidance from downstream manufacturers like Intel to downstream manufacturers. With notebooks equipped with Intel Core 2 products, The performance is getting higher and higher, the appearance is getting thinner and lighter, and the battery life is also constantly improving. It can be expected that this trend will be more obvious in 2009.

Feature two: The impact of the financial crisis on business computer purchases: high cost performance requirements, mainstream trends in mobile performance and security

The impact of the financial crisis on the procurement trend of business computers can be seen from a "2008-2009 China Business Desktop Computer Industry Research Consulting Report".

The financial crisis has led to a reduction in procurement budgets, which has made major companies extremely picky. There is a dialect in Sichuan called "eating bully", which is similar to "cheap price and sufficient quantity", and it is manifested in the commercial PC market-faster, higher performance, better mobility, and cheaper prices.

This point, from the performance of simple "CPU products", we can already see more trend performance. Take Intel Core 2 as an example:

The number of Core-integrated transistors built on the 45-nanometer process technology has reached 291 million. The advanced process improves performance while reducing Core production costs, allowing users to buy higher-performance products at lower prices. 2009 is the year when the 45-nanometer processor fully occupied the market. Major manufacturers have launched more Core series products based on 45-nanometer process technology. The mainstream processors have ushered in the 45-nanometer era. Similarly, the lower manufacturing process also brings a reduction in energy consumption. With a 40% increase in performance, energy consumption has also decreased by 40%. The reduction in energy consumption has not only reduced the user's cost of use, but also caused its heat generation to vary. The reduction reduces the complexity of the system while ensuring that Core does not need an overly complicated and heavy cooling system, which makes the portable platform lighter and more flexible. It can also distribute the saved weight to the battery system to improve its battery life. When the financial crisis had not yet begun in early 2008, the prices of memory and LCD had plummeted, and the motherboard market had also been extremely bloody.

In addition, in addition to the above factors, it has also been noticed that, whether it is a product manufacturer or an enterprise buyer, more and more safety is taken as an important reference condition in the market. The main manifestations of security are reflected in the following points: the authenticity of information and entities can be identified; the information can not be leaked to unauthorized persons or entities; the consistency of data can be guaranteed, and the data can be prevented from being established without authorization. Modification and destruction; ensuring that legitimate users' use of information and resources will not be improperly denied; being able to control how people or entities use the resources. From this point of view, the mainstream business applications are indeed in urgent need of advanced security technologies to meet these security requirements.

Continue to use Core as the representative to carry out related discussions. The Core 2 vPro processor platform introduces hardware data security into the chip-level field, making Core processors an ideal choice for mainstream business applications. This security technology protects data in virtualized computing environments from software attacks, virus intrusions, and other types of threats. Through continuous security and management agent presence inspection, it can effectively prevent illegal tampering and achieve the best data security and data protection. At the same time, it can also enable IT managers to remotely monitor and maintain. IT managers can handle it without having to be on the front line. Problems to improve the response speed and efficiency of troubleshooting. It can also enable IT administrators to perform daily patch installation and other security maintenance by remote wake-up during non-peak usage hours to prevent problems before they occur.

At any time, high cost performance, advanced mobility performance and security enhancements are the mainstream trend of commercial use in the PC market.

In addition, looking at the PC market in China, there are two business groups worth paying attention to: the rural market and small and medium-sized enterprises. For the PC market, it seems more important at this stage to study changes in the purchasing psychology of small and medium-sized enterprises, and to develop targeted market products and marketing strategies.

Feature three: SMEs need more targeted PC products

In the current PC manufacturer's product list, the segmentation trend of commercial PCs is not yet clear. This may require reflection, and SMEs should be the least overlooked. According to a piece of data from iResearch, the number of Chinese SMEs has reached 31.518 million in 2006. By 2009, this number is expected to grow by at least 10 percentage points. This is a very huge market, and there is no reason to not pay special attention to it.

In fact, future PC growth depends on two points-the rural market and the SME market. In 2009, everyone's eyes were more on the PC to the countryside. As the most important driving force, upstream manufacturers such as Intel clearly lead the market change, and more targeted products are brought to SMEs, even those with only one employee Entrepreneurial enterprise.
