Without looking to your link, i guess it is a x87 float benchmark, because
Athlon32 don't has SSE2 to compare with. A bit outdated for Opteron's sixteen
128-bit XMM-registers and appropriate compiler and libs. Forgot all this opteron
benchmarks, until all the dev tools are ready to produce optimized 64bit code
and SSE2 float/double instructions. SSE2 even became faster, future Hammers will
have "direct path" SSE2 instructions instead of "double direct path".
