I have ported my go board engine from my laptop to a desktop, and I wanted to pass on these benchmarks. Laptop T2300@ 1.67G 533MHz memory - Cygwin/Windows Desktop 920-i7@ 2.67 G 1066 MHz memory - Ubuntu
After factoring out cpu-speed, my go code runs about 1.25 times as fast on the new processor. Since it mostly fits in cache, some is probably due to the improved cache and the rest is the improved CPU. This means that cpus haven't improved that much in the last 3 years. I ran multiple copies of the benchmark at once: 1 copies: 100% 2 copies: 100% 100% 4 copies: 100% 100% 67% 67% 8 copies: 67% 67% 67% 67% 67% 67% 67% 67% Hyper-threading works pretty well on the i7. So, with little cache conflict, you should expect about 5.33 times as much work, as a single processor, which is useful to know.
