When you have 33% more cores, you better get 20% on average. Where is the miracle though?


You can't do math can you? All the evidence so far has pointed to fairly good gains in IPC (just look at Dresdenboy's work), there is literally no logical reason to think that it will be slower.
Ah the irony...Please tell him his math is also wrong.

Are you quoting me on those ? If yes, I don't remember saying that.

OTOH, answering messages 2 months old deserves some attention and those statements are valid : Nehalem and its 32nm derivate are at least 50% faster in any meaningful app ( and I mean commercial workloads, not games ) than the Core 2 generation. I can back that up with dozens of world records for any given socket number.

As for being the greatest, well, what can I say, I let the market decide :

Around 400 million 45nm Nehalem processors have shipped to date, Perlmutter said during a speech at IDF

It is the biggest achievement at least to date given stellar performance, energy efficiency, scaling and features. Whether the new uarch, Sandy Bridge can expand on this remains to be seen.
