If the question is addressed at the latest uptodate processors, the general consensus is that the top end AMD Barton is faster at running general applications while the top end Intel can lick the pants off AMD when it comes to CPU bound programs. So if all you do is play games or design aircraft then the Intel is for you, but for those of us who are a bit more staid in our computer ways, we will get there quicker with our AMDs.
You've looked at the link that does the tests - so what's the problem. It's clear that all other things being equal, the P4 2.8C, with the 800FSB, and hyperthreading, is substantially faster that an Athlon XP3000.
You must also remember that "speed of a PC" depends on more than just the processor - that's why Toms test are valuable, in that they keep the other components the same, so they show up the differences in processor speeds. But you buy an overall package, so you need to take everything into account.
To those that haven't looked at Toms results, I suggest you do.
As things computer are now so fast, choosing one speed CPU against another is a bit academic.
I would hesitate paying through the nose for a top speed processor when next week it is likely to be bargain basement price having been superseded by something a bit faster. With the money I had saved, I would buy something more useful.
I am using an AMD based PC (like all my past PCs, other then the very early Sinclear and Pentium 486!) with an Athlon XP 2100+ processor and I am giving an opportunity to upgrade my motherboard, processor and memory. Thank you all for responding, I agree with your comments and I decide to go for a Pentium P4 2.8 CPU and a Gigabyte GA-8KNXP motherboard combination. I hope I won?t regret it!
