Intel's Answer to Cell: The Teraflop chip

When Sony's Cell architecture was first introduced, everyone looked to Intel for an answer - and the best we got was that the foreseeable future of multi-core computing would be x86 based. When Cell was first announced, Pro Acessor with 9 cores was unheard of as we were just being introduced to Intel's dual core offerings and quad core was just a pipedream. By the time the PlayStation 3 launches, dual socket Xeon systems will be able to have the power of 8 very powerful x86 cores and all of the sudden the number of cores in Cell stops being so impressive. But there is quite a bit of merit to Cell's architecture and design, as Intel has alluded to many times in the past, and today Intel showcased Pro Acessor that is very similar in design.



Intel outfitted a single chip with a total of 80 very simply cores, that combined can execute a peak rate of 1 trillion floating point operations per second. Each core uses a very simple instruction set, only capable of executing floating point code, and are individually quite weak. But the combined power of the 80 cores is quite impressive, and it's directly taking a page from the book of Cell. While Cell's SPEs are likely more powerful than each of the cores in the teraflop chip, the design mentality is similar.



The facial expression is a side effect of holding a wafer of teraflop chips

Intel showed off a wafer of these teraflop chips, with a target clock speed of 3.1GHz and power consumption of about 1W per 10 gigaflops - or 100W for 1 TFLOP. The chip is simply a technology demo and won't be productized in any way, but in the next 5 years don't be too surprised if you end up seeing some hybrid CPUs with a combination of powerful general purpose cores with smaller more specialized cores.

不行的, 顶多可以模拟shader的数学运算. 其实CELL出来以后, GPU数学运算的优势就开始减弱了.
GPU的优势其实是每个TMU 1cycle的4 * 4值采样+三个线性插值. 再加上各向异性过滤这样的东西, 能把CPU弄死的.

不够？:lol: 那你不是要打Sony的耳光？或者把Sony的PS2一脚踩成渣？

我就是觉得TMU应该由硬件电路做的, 而不是通用部件:)

谁也没说x86要包办一切，如果你记性好的话，Intel说过Many Core里边的异构核心。
这只是原型系统，面向的是Tera级浮点能力。
