Enter the Dragon: AMD AM3 6-core desktop arriving in 2010

6 MB L3 cache does make i hard to see the difference between DDR2 and DDR3.

Applications that use much memory will probably get less performance with prefetch technology.

1 MB per core? It's not funy at all. After all you don't buy such cpu for single thread performance. If I remember it correctly, AMD estimation for specfp was 38% more performance for 50% more cores.
Also even bigger cache can't help to apps with streaming data. We can look at benchmarks from techreport:

100% perf diff going from Athlon II X2 250 to Phenom II 940
90% perf diff going from QX9770 to dual QX9775
41% perf diff going from Ph II x3 720 to Ph II x4 920... hmmm...

38% perf diff going from Opteron 2384 (2.7) to 2435 (2.6) with 3% diff in freq.
