In Response To: Sandy Bridge CPU (Michael Depreli)

Whetstone is the floating point unit speed (Dhrystone is for integer calculation).

XG relies only to the floating calculation so Whetstone is the right benchmark.

Roughtly 50% of the time is spent in floating point calculation using SSE2 or AVX depending of your PC. The rest is regular IA32 instructions.

Overall, however, a combine benchmark is typically sufficient to compare 2 CPU without having to drill down to the specific Whetstone benchmark.
