Default Prescott chips - difference?

Can someone fill me in on the difference between the next generation chips
the Prescott and the current P4s?

Thanks



The well known differences are that it will be on a smaller process
(90nm SOI vs 130nm) allowing the chip to run faster at the same
temperature or even lower temperature, the chip will have a full 1MB of
second level cache vs the current half megabyte, and there will be a
number of tweaks to problem parts of the chip which will probably not be
noticed.

Just issuing a correction. A coworker closer to processes pointed out
that intel's 90nm process is not SOI. I thought I had been told that.
It does use strained silicon, which may be where I got confused. Either
way, expect it to be capable of higher speeds, which is what we care
about in the end, right?
