Intel Pentium the return!

Intel is already heavily pitching its Larrabee technology to its business partners. Even though the technology behind the cGPU still remains a mystery, somehow business men alike are drawn to the new product, who wouldn’t! A German publication has provided more clues based on Larrabee and how its built on two decade old P5 architecture!

This may remind you of Parallel and serial computation but hardware architecture design usually in some way or another use older original design.

In the German Article, when Intel decided to create the cGPU Larrabee architecture they looked into obsolete technology the result? second generation p54C core using Pentium 600nm process.

The first Pentium processor P5 used 800 nm and was clocked between 60 to 66 Mhz and was developed in 1989. The P54C on ther other hand had a clock speed of 120Mhz. Intel also released the P54CS core 200Mhz and 55C Core 230nm, they cores had 250nm and 280nm respectfully.

The Larrabee processor will use 32 cores equppied with new MMX extensions called AVX, this would mean that Larrabee will be used on a 45nm P54CS core. The 32 core also supports 512-bit wide AVX (Advanced Vector Extensions) instead of the old MMX used in previous Pentiums.

The processor is said to run at 2 GHz and have compuation of 2 Tflop/sec. If this is true Intel may be able to hit twice the performance in a single precision calucation as Nvidia and AMD. With both graphics vendors doubling their floating point performance its predicted that GPUs may hit 3 to 4 Tflops/sec in single core Graphical processors.

Take the ATI Radeon 4870 x2 clocked at 778Mhz this has an estimated performance rate of 2.49 Tflop/sec. Lets just see how this turns out!
