What do people think of the 20-25% Hammer improvement over Athlon? Seems a bit underwhelming... Perhaps you are confusing performance with IPC? Remember Hammer has a longer pipe, tuned for higher clock frequencies, hopefully substantially higher. If you look at it in the context of the P4 managing a -30% improvement over P3, but compensating with higher clock, then perhaps you can see that it is perfectly possible for Opteron to kick Xeon's ass with "only" a 25% IPC improvement over Athlon, (or about 75% over P4 Xeon at the same clock speed).

"What do people think of the 20-25% Hammer improvement over Athlon?" If you are talking about IPC, 20-25% improvement is huge...

<< What do people think of the 20-25% Hammer improvement over Athlon? Seems a bit underwhelming, especially considering all the performance hype on the threads the past several months. And, this seems like a best case scenerio... >> Well, since it's 20-25% better at the same clock that seems quite good to me. Someone was saying that there would be 2 ghz hammers in june? If that were true then and they were 20-25% faster per clock, we'd be looking at a quantispeed rating of 2900-3100 at 2 ghz in june, assume a nominal 10-25% increase in speed by release date (which would seem reasonable), and you'd be looking at a 3200-3900 rating at release. Of course, this is based on the 2 ghz in june estimation which I remember, but I'm not sure if this was someone's wishful thinking or something said by AMD. Who knows what they'll do with the rating system in the future either. It seems unlikely that it can stay in it's current incarnation. Either way the performance seems like it will be quite good, but the future will depend on how well it ramps IMO.
