Something New on Hammer (Courtesy of the Colored Font Guy) Just notice the performance predictions for Hammer, and how they tend to get more and more conservative each time we hear them. Remember just a couple weeks ago when Hammer was predicted to have a 35-50% increase in IPC? xbitlabs.com Posted 3/28/02 at 11:57 pm by Rat I came across some pretty interesting info on the upcoming AMD Hammer processor here. As it turned out at CeBIT show in Germany AMD’s technical guys were much more willing to share some info on the new processors than in the beginning of this month at the IDF (see this news story). as a result, the guys managed to find out the following: The CPU with A0 core stepping showcased in both cased worked at the actual core clock of 1.4GHz. The next core stepping A1 is expected to appear in the nearest future and should work at 1.8Ghz-2GHz. The first Hammer CPU will have the performance rating equal to 3400+ (by the way, we have already shared something of the kind last September). The performance of Hammer processor in 32bit code will be 15% higher than that of Athlon XP working at the same core clock. Another 10% performance gain are promised to be delivered when the programs are recompiled in 64bit (without any code changes). Also the info about not only VIA and SiS working on the chipsets for Hammer, but also ALi has been confirmed. wbmw

Elmer, do you know how they took the P4 down to 131.4 mm², from 145 or 146? Serious on this one. This is like an "asynchronous" die shrink isn't it? Yes, this is a mid course shrink and is common. When they have the process running smoothly they can tighten the design rules and shrink the die size. This is another confirmation that their .13u process is very healthy and they have a lot of confidence in it. It's possible we may see another die size reduction before the transition to 90nm but that's just a maybe. EP
