Advanced Prefetching is the NUMBER ONE reason behind Conroe's
performance over Athlon 64.

What do you base this statement on? Intel seems to suggest otherwise in their various comments on the Core2 architecture. And AMD doesn't seem to emphasize (or even mention?) improved prefetching for the K8L:

(From Kanter's RWT post)

I'm sitting in a keynote from AMD's Chuck Moore, and here is information on the next generation i.e. K8L.

0. Native quad core
1. Hypertransport up to 5.2GT/s
2. Better coherency
3. Private L2, shared L3 cache that scales up.
4. Separate power planes and pstates for north bridge and CPU
5. 128b FPUs - see 14,15
6. 48b virtual/physical addressing and 1GB pages
7. Support for DDR2, eventually DDR3
8. Support for FBD1 and 2 eventually
9. I/O virtualization and nested page tables
10. Memory mirroring, data poisoning, HT retry protocol support
11. 32B instead of 16B ifetch
12. Indirect branch predictors
13. OOO load execution - similar to memory disambiguation
14. 2x 128b SSE units
15. 2x 128b SSE LDs/cycle
16. Several new instructions

Coprocessors:
media processing
JVM/CLR acceleration
TOE, XML or SSL processing

Anyway, ours news posting is somewhat broken, so I might not get to turn this into news. But you heard it here first : )
