Intel I7 cpus are SIGNIFICANTLY faster than AMD. Make sure it is an I7 (not I5,..), because they have the fastest memory access and run best with Lapack/Blas (because of the mkl-library) which is very important.
At the moment Intel offers: i7-3820 300$, 130W, 4 cores, 3.6/3.8GHz, 10MB cache, 4 memory channels and 51.2 GB/s bandwidth i7-3930K 600$, 130W, 6 cores, 3.2/3.8 12 , as above i7-3770K 340$, 77W, 4 cores, 3.5/3.9 , 8MB , 2 memory channels !!!! 25.6 GB/s !!! So I would go clearly for a i7-3820 (or if you have more money) for a i7-3930K processor. The last one (3770K) is produced in the newest technology (power saving), but I guess its memory bus is much slower! Am 27.06.2012 13:53, schrieb ali ghafari: > Dear Profs.
