Benchmarks: E3, E5, 6200

Comparing Kurumi (Xeon E3 1230), Midori (Opteron 6272) and A12 at my day job (dual E5 2620)

Threads Kurumi (E3 1230) Midori (6272) A12 (E5 2620 x2)
1 385 289 241
2 771 564 477
4 1216 1085 958
8 1627 1819 1930
16 1629 2116 3032
32 1626 2178 3126

The E5 2620 is the only dual-socket system, and is the most expensive of the three.  It also offers the best performance under heavy load - not surprising given the greater CPU resources - but as expected, lags behind under lighter loads due to the slower clock speed.

My performance model predicted a peak score of 3055; it actually outperformed that slightly, but I was pretty close.
