That's throughput server performance.You also fail to understand that when everything is loaded up in Orochi,due to shared design we have roughly 25% "penalty".This is average number since AMD stated BD shared design offers an average of 80% performance of CMP approach(hypothetical BD with no shared resources). To muddy the waters even more we have an aggressive new Turbo ability which will be more useful in desktop due to nature of workloads there. Then you have FMAC(floating point unit) vs integer IPC etc.

My point is you cannot use the "50% more throughput" statement to accurately extrapolate desktop performance.
