I have bought a AMD phenom II x4 965 with 4 cores at 3.6 GHz. I have tested against intel i5 760 with 4 core at 2.8 GHz. I made two tests, one with pure integer operation (MC Go simulation), another with some floating point operation (some other type of MC simulation). The result is quite interesting. The intel cpu is 20% faster on simulation containing some floating point operation, while the AMD cpu is 20% faster on pure integer operation (MC Go simulation). So, basically, what i found is that intel i5 and AMD phenom II of same frequency has similar performanc(5% slower) on pure integer operation. So amd 1090T with six cores would have about 50% performance gain on i5 760 with 4 cores.
Hope this is helpful to people who building Go playing clusters.
