Intel's First Nehalem Cpu-Z Pic.

OBVIOUS FAKEInfact, AMD's upcoming 45nm K10 derivate (dubbed Shanghai) will bump the green team's L2 to 6MB...

6MB L3 actually. I believe L2 will stay at 512kb per core. 256k is a bit low for L2 cache. If its true savantu might very well be right on this one(instruction cache only).

Um, Intel is *on the record* with the claim that Nehalem even has better single-thread IPC than Penryn. Then there's the claim that Nehalem has 1.6 times the SpecInt_rate performance of Clovertown, and 2.6 times the SpecFP_rate performance. (That's in dual-socket QC systems @ 3GHz.)

So, I'd say you need to adjust your "implications" accordingly.

Whatever Intel has done with Nehalem's cache, Nehalem is blazingly fast.

I thought SpecFP/Int_rate are bandwidth benchmarks
Needless to say just having an IMC and QPI would boost "rate" benchmarks significantly and does not imply better single thread performance.
