Peak DP GFLOPs for 2500k at stock?

[Anarchist420]

What is the peak double precision FP performance for a 2500 k at 3.3 ghz?

What should I expect to sustain at stock clock, 8 GB ram, 128 bit 1.333ghz, and 7-7-7-21-1t timings? When I ran linx pack or whatever it's called, the highest it went was about 75gflops, although I don't know whether that was dp or sp... if it was single precision then the double precision would be ~38gflops, if it was 75gflops DP, then it would be 150 gflops sp I'm assuming.

It has two 256-bit floating-point AVX units per core (one MUL, one ADD). That's eight double-precision floating-point operations per cycle. Hence 8 ops * 4 cores * 3.3 GHz = 105.6 DP GFLOPS.

Sounds about right for sustainable DP GFLOPS.
