Stop it already....
Intel is a huge publicly owned corp that has stockholders to please, their stock is up and times are good. There is not a chance in hell that the Prescott will be
a) slower than Northwood
b) unfeasibly warm
c) low headroom.
This is the same basic core and process that will take Intel to 4.0gHz by Q4...4ghz in a closed OEM case in a stuffy office in Kuala Lumpur....I expect the Prescott to be 5% faster than Northwood, and more overclockable. 3.4 should hit 4.5 (screenshot) on stock Prommy m2...Under top notch phase change, Prescott will be benching 3D at 4.7ish, with some top OC'ers benching superPi/Pifast at 5+, even 5.3...The first 5ghz 3DMark run may very well be on a Prescott!
