Announcing the next generation CPU technology which supports Intel and green IT

Intel December 17th, up-to-date held the technical seminar "the Intel platform technical seminar 2007 which" announces CPU of the same company/platform technology. The shaker baud car which serves the Intel felloe and the microprocessor technology laboratory director in the corporate technology generalization headquarters of the United States Intel (Shekhar Borkar) the person the Noboru platform did in keynote presentation, explained the future CPU image and the next generation technology which actualizes green IT.

As for Intel CPU, 45nm (nano- meter) refining advances to production process in 2007, improvement is advanced to the extent to which also the number of transistors accumulates 80 hundred million. The same company in the future conformed to Moore's law, it is the policy of promoting the production process reformation of CPU 2 years, but according to Borkar, you say that improvement pace of extent performance and the electrical efficiency where refining advances knocked down slow.

On the other hand, depending upon application TFLOPS (tera- FLOPS) it is designed in such a way that computing efficiency of level is required, improvement of continuous CPU efficiency and low electric power consumption conversion becomes the focus of future engineering development as Intel. The fact that Borkar shows then, is the multiple core conversion of further CPU.

Borkar listed CPU of 22nm production process to example, when 12 cores/48 cores/144 cores and changing the number of cores at the same tip/chip size, announced the relative data of total performance. According to that, when two applications are processed in parallel, compared to 48 cores/144 cores, the result that was shown 12 cores whose efficiency per core is high throughput are higher. But, the number of applications which process in parallel becomes 4 or more when, from, when the method which increased the number of cores is related to the performance improvement of altogether, Borkar explained.

"Rather than improving one core from this, throughput improvement with the total with multiple core conversion becomes important", (Borkar)

In addition, as for Borkar, introducing the economical electrical effect which is obtained by the fact that electric power is controlled finely in every core. "Full it makes the core work which is, a certain core while by the fact that finely electric power it controls each core, improving, can control electric power consumption (Borkar) e.g., it makes work with 70%,". In addition, work of the core which becomes feverish excessively was stopped, also hopping function between the core which makes operation seamless continue and laminating technology etc. of the tip/chip which actualizes the acceleration of the memory bus, were introduced to another core by Borkar.

Borkar lastly, "must clear for further multiple core conversion, the topic is mainly left, but we even from now on continue to challenge as an engineer", that, directing to more engineering development, you talked the enthusiasm.
