Tony: looks like P4 has a lot of clock speed headroom, power not that bad also.

Remember that Intel does not specify the max dissipation for the P4 and openly admit (see P4 datasheet) that the processor can consume more when running "high power code". The AMD and Intel power dissipation numbers are therefore not directly comparable (although I would agree with the person you quote, that the Athlon does consume more - esp. on a clock-normalized basis).

Re: the Pentium 4 1.3, 1.4, and 1.5 GHz processors

It ramps like a banshee, all right. That must be why the 1.5GHZ part was followed so quickly by the even more impressive 1.3GHZ part after only 2 short months of additional development time.

many users even breaking the 1.8 GHz barrier with their new chips. Over in Japan, they've hit over 2.2 GHz with current Pentium 4 chips

I think Intel is just sitting on higher speed P4s because AMD is non competitive at this point. As soon as AMD gets closer look for Intel to widen the gap.

Tony,

Thanks for the good review on the P4. I had about given up on that chip after listening to Scumbria and the rest.

"looks like P4 has a lot of clock speed headroom, power not that bad also. - Tony"

Looks like you need to pay a little more attention to
what people found and posted here with respect to
P4 clocking abilities. You seem to miss the feature
of P4 when it automatically throttles down its clock
when the power threshold is reached. I bet those 1.8
and 2.2GHz Japanese systems are effectively running
at the same 1.3 or 1.5 GHz depending on size of heat
sink and weather conditions.
