Re: "Without FET's with high drive currents (940ua/um N, 420ua/um P), Low K dielectrics, ... AMD doesn't stand a chance at keeping up in the "Mhz race" (tm Yousef)." Not with their current architecture I agree, however AMDs arguement is that with deeper pipelines - read: fewer gates between flops, they can achieve higher frequencies because of shorter delays between stages. My question is that if this is true shouldn't we see the other devices using this technique enjoying the same benifits? Why does IBM need copper to still fall behind Intel in the mhz race? They use RISC design techniques. So does SPARC and they're lower frequency as well. Why? Alpha seems to be the only one who can ship in limited quantities with high frequencies but their new 21264 that is just beginning to limp out the door is at 500mhz. EP

Yousef, Neither of these processes will be able to support a 700mhz "screaming core" or 200mhz memory. Once again, you are not considering the impact of architecture on clock speed. Can the 0.35u process which the 21164 is built on support 700 Mhz? If K7 is already running over 500 Mhz, it would not be a bit surprising if some speed work brought it up to 700 Mhz. In fact, it would it would be extremely surprising if it couldn't hit 700 Mhz in the current process. Scumbria
