Guys,
I just got my hands on a Phenom X4. My understanding was this was the desktop
version of the 3rd gen opteron (K10h). I expected it to have the same FPU
peak: 4 flops/cycle double SSE, 8 flops/cycle single SSE, 2 flops/cycle x87.
However, all my tests indicate it is 2/4/1 (I installed the Goto BLAS as well,
and they also run at 1/2 speed compared to opteron). The Athlon-64 was 2/4/2,
so it appears to be much crappier than the previous generation hardware.
Does anyone have any insight here? The AMD techdocs all lead me to believe
4/8/x (no mention of x87, so crippling that is not as suprising).
?
Clint
