Performance of current central processing units may impress, but nothing impresses more than the speed of the forthcoming products. Both Advanced Micro Devices and Intel Corp. have released SPECfp_rate2006 and SPECint_rate2006 test results of their unreleased processors recently on their web-sites to impress the public.

If SPEC benchmark results published by AMD and Intel are to be believed, then a system with two Intel Xeon quad-core microprocessors based on the new micro-architecture at 3.20GHz clock-speed will offer much higher floating point performance than currently available dual-processor server machines. While the results of a 2P machine featuring a pair of quad-core AMD Opteron at 2.50GHz reveal potential, its performance is much slower compared to a 2P Intel Xeon 5400-series-based machine (with 3.20GHz CPU clock speed and 1.60GHz processor system bus speed) in the crucial SPECfp_2006, according to Intel (see slide 18 of this presentation).
