What Is a Multi-Core Processor?

Multi-core processor refers to the integration of two or more complete computing engines (cores) in one processor. At this time, the processor can support multiple processors on the system bus. The bus controller provides all bus control signals and Command signal. The development of multi-core technology stems from the engineers' recognition that simply increasing the speed of a single-core chip will generate too much heat and not bring corresponding performance improvements, as was the case with previous processor products. They recognized that at that rate in previous products, the processor would quickly exceed the surface of the sun. Even without thermal issues, the price / performance ratio is unacceptable, and slightly faster processors are much more expensive.

In 1971, Intel launched the world's first universal type

From the perspective of application requirements, more and more users will be involved in a multi-tasking application environment during the use process. There are two typical application modes in daily applications.

An application mode is a program that uses

Multicore processors represent an innovation in computing technology. Because of the globalization of digital data and the Internet, businesses and consumers have begun to demand performance improvements from multi-core processors, and this important innovation has begun;

From Power, UltraSPARC T1,

On the afternoon of September 6, 2009, Intel announced in Beijing the industry's first quad-core Intel & reg; Xeon & reg; 7300 series server processor designed specifically for multi-way (MP) servers. Compared with Intel's previous generation dual-core products, the six new quad-core Xeon & reg; 7300 series processors released this time have doubled and tripled the performance and power consumption, respectively. With the release of these products, Intel completed the rapid switch to the innovative and energy-efficient Intel® Core microarchitecture in less than 15 months.

It is understood that the launch of the Xeon & reg; 7300 series products includes a processor with a frequency of up to 2.93GHz (power consumption is 130W), several 80W processors, and a four-socket blade server and high density 50W processor optimized for rack server (clocked at 1.86GHz). The Intel® 7300 chipset with Data Traffic Optimizations features a balanced platform design and features a number of new technologies to improve data transmission between processors, memory, and I / O. In addition, Intel also announced a 50-watt (12.5-watt per core) processor to promote the development of energy-efficient ultra-dense deployment products such as four-socket blade servers and high-density rack servers.

In terms of chip design, in addition to doubling the number of cores, the memory capacity supported by the Xeon & reg; 7300 series processors and Intel & reg; 7300 chipset is 4 times the original compared to the previous Intel multi-channel platform, and Can support very high integration ratios to reduce space, power consumption and operating costs.

It is expected that more than 50 system manufacturers will release servers based on the Intel® Xeon® 7300 series processors, including Dell, Egenera, Fujitsu, Fujitsu-Siemens, Hitachi, HP, IBM, NEC, Sun, Ultra Wei and Youli etc. For channel customers who need a complete platform based on the new Intel & reg; Xeon & reg; 7300 series processors, Intel has specially provided Intel & reg; S7000FC4UR server platform. This platform provides robust scalability and proven enterprise-class reliability for infrastructure virtualization and consolidation.

Many software vendors also provide innovative solutions that support virtualization and performance scaling for platforms based on the Intel® Xeon® 7300 series processors, such as BEA, Microsoft, Oracle, SAP, and VMware. In addition, the Solaris operating system and the thousands of applications running on it can take full advantage of the leading performance advantages of the Intel & reg; Xeon & reg; 7300 series processor platform to provide Intel & reg; Xeon & reg; server users with enterprise-class, support-critical Task UNIX operating system environment.

These new quad-core processors are priced from $ 856 to $ 2,301 per 1,000 units, depending on the frequency, features and customer order.
