A while back around July or August I had bought the following stuffs:
1) 2 x AMD Opteron 6168 1.9Ghz, 12-core Magny-Cours CPUs
2) 1 Asus KGPE-D16 Dual Socket G34 motherboard
3) 8 1GB Kingston KVR1333DE9S (ECC) DDR 1333 DIMMs
4) Lian Li PC-P80 case
I bought it because I was curious about folding performance of the Magny-Cours chips and how it compared with the current Xeon line-up of chips.
Outside of Bit-Tech.Net which compared dual Xeon x5650s and dual Opteron 6174, there wasn't really much out there, and this comparison was done using BigAdv A2 units, which were de-commissioned by this time.
Anyway, I found the performance was very close to a well-overclocked Core I7 980x running at 4.1 Ghz or higher, except on BigAdv 2684 units, where the dual Opteron could out-fold even a 4.4Ghz Core I7 980x.
Generally I was getting between 55 - 60K PPD on 2685, 2686, and 2692 units and around 42K PPD on 2684 BigAdv units. Not bad, but I wanted more!
