How Do I Choose the Best Laptop Processor?

The processor of the notebook computer is basically supplied by 4 manufacturers: Intel, AMD, VIA and Transmeta. Among them, Transmeta has gradually withdrawn from the notebook processor market and it is rarely seen in the market.

Notebook processor

The processor of a notebook computer is basically supplied by 4 manufacturers:

The processor can be said to be the most core component of a notebook computer. On the one hand, it is the component most concerned by many users. On the other hand, it is also one of the most costly components of a notebook computer (usually accounting for 20% of the total machine cost). Of the remaining 3 homes,

For the human body, the heart is a very important organ, and it is also the most basic guarantee for human survival. The heart is not only important, it also often becomes an important basis for describing people. Good-hearted, broad-minded, too soft-hearted, etc. can be used to evaluate how a person is. In fact, for a notebook, the CPU is equivalent to its heart, and the performance of this notebook can also be evaluated by the CPU. Generally speaking, through the identification of the CPU, the price, overall performance, portability of the relevant notebook can be introduced, and even other configurations on the hardware can be introduced. Today there are many forms of shopping guide articles about notebooks, but the analysis of different processors leads to very few shopping guides. This is often the part that many consumers care about before buying a machine. Below, the author will introduce four excellent processors with relevant processors through the introduction of the four types of processors to share with consumers. Consumers can choose different processors according to their own conditions in order to choose their favorite notebook.

In fact, when it comes to processors used in notebooks, you have to mention INTEL, AMD, Transmeta and VIA. But since Transmeta has now withdrawn from the processor industry, its products have disappeared from the market, and for VIA, its processors have also appeared in the new Blue 2999 notebooks, so the pen is only for INTEL and AMD today The processor is introduced. Since it is Intel and AMD in the processor manufacturer, these four processors are naturally Pentium M, Celeron M, Hyun Long and Sempron.

Pentium M Q30

Pentium M is a processor developed by Intel for notebooks, and it has been widely used in notebook platforms. And from the beginning Banias core to Dothan core, it is the most important structure of Centrino and Centrino 2. In fact, Pentium M is based on the Pentium III processor core. After "(1) improving instruction execution structure, (2) using advanced instruction branch prediction technology, (3) doubling the secondary cache capacity to 1MB "And so on.

The first generation of a PentiumM processor with a 0.13 micron process, also referred to as the Banias core, has 77 million transistors, a grain area of 82.8mm2, and a maximum core operating frequency of 1.7GHz. The QuadPump technology is used to transmit data at four times the frequency of the main operating frequency of 100 MHz, achieving a transmission effect of 64-bit Bus equivalent to 400 MHz.

The core architecture of the second-generation 0.09 micron Pentium M processor (Dothan) is not much different from the first-generation Pentium M (Banias). It also has a 64KB L1 cache (32KB L1 I-CACHE + 32KB L1 D- CACHE), and 3way SuperScalars (three-line ultra-scalar) design near Pentium III (P6); in addition to doubling the second-level cache (L2Cache) to 2MB, it is twice the number of the first generation Pentium M, and the second generation 0.09 microns The number of Pentium M transistors in the manufacturing process also skyrocketed to 140 million (140 million).

Later, Pentium M entered the notebook market with the 915 chipset and a new wireless chip to form the SONOMA platform. With its strong portability and ultra-low power consumption, it was praised by the market. flowering.

Here we introduce a Pentium M-based notebook, which is Samsung's first 12`1 inch notebook computer Q30.

Q30

Q30 is the first 12`1 inch notebook computer launched by Samsung, with a body weight of only 1.1 kg. It is a stylish notebook with great portability. Its cloud-like design and petite moving body are just like AE86, so you can't bear to use them. And its price, like AE86, is not a sky-high price in its own industry. It is definitely a most suitable choice for white-collar workers and MMs who are pursuing fashion.

The Q30 uses an ultra-low voltage version of the PentiumM processor with a frequency of 1.1GHz (built-in 2MB L2 cache), and comes standard with 512MBPC2700 (DDR333) high-speed memory. A DVD-CD-RW combo drive is configured, which is connected to the Q30 through a 6-pin FireWire (IEEE1394) interface, which not only provides high-speed connection, but also eliminates the trouble of external power supply.

Complete ports, including external display port, 6PIN standard IEEE1394, two USB2.0, wired LAN / MODEM interface, SD memory card / memory stick dual card slot, CF card slot, etc. The Q30's decisive screen has abandoned the PCMCIA slot that was widely believed to be necessary for notebooks in the past, and replaced it with a CF memory card slot that is now widely used in digital cameras and PDAs.

Celeron M Rising Sun 150C

Celeron M is a low-end mobile processor released by INTEL in order to compete with AMD in the low-end market, but it uses the same application architecture as Pentium-M. And the Dothan kernel CeleronM is very close to the Banias kernel Pentium M in terms of hardware indicators, but it reduces the cost by reducing the second-level cache, and it does not support Intel's "SpeedStep" power saving technology. However, for notebook manufacturers, by adopting Celeron M and not equipped with a wireless network card, this can save the whole machine cost of more than one thousand yuan, so that it can launch lower-priced notebooks and better compete for the low-end market. For consumers who are not demanding in portability but want to save money, buying a Celeron M-based notebook is a good fit. Here we look at a very popular notebook Rising Sun 150C in the market.

Lenovo Rising Sun 150C

Next, let's take a look at Lenovo's upgraded and reduced price Rising Sun 150C. In the summer promotion, the Lenovo Notebook Rising Sun 150C has become a user concern again with its 15-inch large screen, 5 hours of long standby time, and mainstream configuration. Star products. From the perspective of product configuration, the Lenovo Notebook Rising Sun 150C is undoubtedly equipped with today's mainstream notebook configurations.

This original 6999 yuan notebook is equipped with Dothon as the core CM processor, clocked at 1.4GHz, using Intel855GME as a chipset, memory is 256MDDR333, hard drive is 40GB, built-in COMBO optical drive, supports infrared, 15-inch TFT LCD screen. The only flaw in this book is that its body weight is nearly 2.8KG, which shows that its portability is relatively poor.

The interface is relatively complete, with PCMCIA interface, VGA interface, RJ11, RJ45, microphone, headphone / audio output, laptop keyhole, this keyhole can increase the security of books, 1 IEEE 1394 and 3 USB2.0 interfaces, Very convenient for expansion with other digital products.

Turion 64 Ferrari 4000

Turion 64 is a thin and light notebook processor released by AMD that can support both 32-bit and 64-bit applications. As the industry's first mobile 64-bit processor, it has a variety of new processing technologies, including HyperTransportTM, which can effectively eliminate I / O bottlenecks, increase bandwidth, and enhance application response capabilities. To improve overall system performance. Secondly, in the 64-bit system advocated by AMD, the Northbridge chip also retired and became a "historical term." Turion 64 has a built-in memory controller, which directly connects the processor to the memory, which greatly reduces the memory response time. As a result, the memory belt is up to 3.2GB / s. This not only makes the Turion 64 more powerful, but also makes the motherboard cost quite low. Once again, the Kion-based display architecture of the Turion 64 can bring gaming performance to near perfection. Then with a strong graphics card and a good LCD, then the Turion 64 will be outstanding in multimedia and gaming performance!

However, although AMD s performance and speed improvement is remarkable, it still cannot escape the high power consumption and high heat dissipation fire core. It is tested that its heat generation is between 25-62 watts, and Intel The Pentium M laptop processor heats up only about 20 watts. Although Turion 64 has strong performance, compared with the concept of low power consumption, high performance, and thin and light mobile advocated by Intel Centrino architecture, it still cannot get rid of AMD's weak power consumption in the mobile field. However, its biggest advantage is that its price is very low. For more than 10,000 yuan SONOMA notebooks, ordinary consumers may prefer Turion 64, because this can save a lot of money to upgrade other equipment. When it comes to Turion 64, the notebook we must introduce is the very individual Ferrari 4000, which uses a T64-bit processor.

ACER Ferrari 4000

The unique thinking belongs to ACER's Ferrari 3000, Ferrari 3200, Ferrari 3400 and Ferrari 4000 based on Ferrari design. As the official designated supplier of the Ferrari team, these notebooks released by Acer are full of technology and sports. It feels that its combination with the perfect concept of Ferrari has won the pursuit of Ferrari enthusiasts. Today we will look at this 4000 just released at the end of May.

The overall design concept of the Ferrari 4000 on the one hand adopts the R-corner integrated cover design of the Acer Folio briefcase. At the same time, compared with the previous three models, the appearance has been greatly adjusted, while retaining the original red gorgeous features. At the same time, it added a calm temperament mainly in black, adding a few mature aesthetics to this beautiful product. The configuration uses AMD's latest 64-bit processor Turion64 (Hyunlong), the main frequency reaches 2G, 15.4 widescreen design, 1680 × 1050 ultra high resolution, ATIX700128M independent graphics memory graphics card, 100G ultra-large capacity hard disk, slot-type DVD full burning Optical drive, etc., all configuration modules are trying to make the overall system complement each other from the appearance to the kernel, coupled with Acer NEWPI's fast e key, showing the high standards of the new generation of top-notch laptop everywhere.

Sempron NEC A2100

The Mobile Sempron processor is packaged in PGA format and has a built-in 128KB cache, of which the first and second caches are also 64KB, making the processor positioning convincing in portable notebook computers. In terms of performance, it supports 3DNow! Professional, SSE2 and other multimedia extension instructions, and supports PowerNow! Technology to save battery power in laptops. In addition, this processor also supports AMD s "Enhanced Virus Protection" virus protection technology, and can work with Windows XP SP2 "data execution protection" technology to defend against "buffer overflow" virus attacks, from this point of view Its advanced nature has far surpassed the Intel Celeron-M processor currently prevailing in the low-end market price, but its heat generation is not as low as CM, which limits the portability of the notebook.

Compared with AMD's T64-bit processor, both use 90nm manufacturing process, the highest power consumption is 25W, both support the "PowerNow!" Technology of power management, and both have 800MHz AMDHyperTransport front-side bus. The difference between the two is that Turion 64 supports 64-bit technology, supports SSE3, and has a larger second-level cache. However, because the operating system and software used today are 32-bit versions, this limits the use of Turion 64. The classic notebook based on Sempron to introduce to you is NEC's A2100.

NEC A2100

NEC A2100 uses NEC's own SSV dazzling screen with a bright screen of 320 lumens. It has excellent performance in images, home audio and video entertainment, etc., and can be used as a home machine. The beautiful appearance is also a Japanese machine The unique charm, I believe that the viewing at home will be greatly improved.

Its specific configuration is as follows, using AMD Sempron 2600+ processor, 256MB DDR memory, hard disk is 40G, Sis Mirage graphics chip, built-in COMBO optical drive, and 15-inch super wide-angle dazzling screen, 320 lumens. Other aspects, including three USB 2.0, IEEE1394 FireWire interfaces, RGB and other comprehensive expansion interfaces, built-in 56k MODEM, 100M adaptive network card, pre-installed genuine Windows XP system (home version), and also built-in Smart Restore key The recovery function, the weight of the whole machine is 3Kg, is not very suitable for portable use, but it is still very suitable as a home machine.
