Larrabee architecture sketch
Last month, Intel reported the Larrabee featuring IA(Intel Architecture) core, which means it can adapt present x86 architecture. And now we get to know that the IA core is actually P54C, which is well known for over 13 years since the Pentium 75, according to Pat Gelsinger, the Intel’s Chief Technology Officer.

Meanwhile, Gelsinger said the Larrabee will be a 45nm product featuring SIMD technique, 64-bit address. Besides, 32 of cores runing at 2.00 GHz will unleash 2 TFLOPS capacity, twice as much as the RV770XT. And what’s more, this monster requires a 300W TDP, which also frustrates NVIDIA’s biggest monster.
