Scumbria, Re: In contrast, the 21164 runs at 700MHz in a 0.35u process Do you happen to know what is happening to these 21164 ? It seems that Compaq no longer sell them. Gary

Scumbria, No disagreements here. I expect K7-core to do scale much better than PIII-core given comparable processes. It has been almost a decade since the last time I did any serious engineering work on processor architectures. I just wanted to get some clarification on your comment and also see if you have an architectural insight that I could benefit from. Chuck

<The single cycle L1 access of P6 indicates to me that the pipeline is not balanced. ... In contrast, the 21164 runs at 700MHz in a 0.35u process.> I assumed that the 21164 uses a small L1 cache that requires only a single cycle to access. Funny how the 21164 currently runs at higher speeds than the 21264 with the multi-cycle L1 cache. Correct me if I'm wrong. As for a high school kid trying to extrapolate Intel's own speed limits, I totally agree with you. That's why I said Anand was trying to predict the future again. It might make for nice material to fill the pages of a college freshman's research project, but that's about all it is worth. (Yeah, I know he's not even in college yet, but he will be soon.) If Intel felt that 600 MHz on a 0.25 micron process was economically feasible to pursue, they'd do it. Tenchusatsu
