			Going on a review that I read (which I'll try to find) I think it's open for debate that they are better.

In some regards they are worse... Performance is rougly the same clock-per-clock in most programs. They have a massively long pipeline, which can be both good and bad, generally good since it will help them ramp up speed. Really, the biggest disappointment with them is that they're just as hot despite the newer process. They do have SSE3, although I don't know of anything that takes advantage of it yet.

Intel will just keep pumping these out for a while, AMD has nothing to fear in the short term.

			It's just the roadmap, they won't be able to push the Northwoods much higher so the Prescott is just the next generation. True it DOES have have a longer pipeline AND a bigger L2 cache (a full Meg), but at current clocks the pipe slows it down and the L2 doesn't currently fill in an efficient manner, but they theorize that after like 3.4GHz or so the process will really ramp up... Anandtech... explains it all really well... it's just like how the early P4s were inferior to the later P3s, but the P4 architecture allowed for higher clocks so after time it proved worthwhile... I'm an AMD supporter through and through so none of it matters to me anyway... except come December when I get to purchase whatever the hot Intel CPU and Mobo combo is for $200 then resell it on eBay for $700! :thumbs-up: ~Krelian

			The point of Prescott was support of AMD's x86-64, but it's disabled in current revisions for some reason (probably because it doesn't work correctly, which Intel has hinted at). It's still a bit unclear whether future Prescotts will have the support fixed and enabled or if it will be called something else.

They're probably going to wait for their newer platform so they can rake in more cash.
