Those links are crap.. I'm sorry.. but they are all pro-Intel garbage. WRONG WRONG WRONG. We all know the AMD 64 wipes the P4 off the map into hell.
The prescott sucks:
First, Prescott definitely does not represent monkey business, as it performs at the same level as the Northwood. In addition there is the unknown thing called SSE3, the use of which remains to be seen. That is a summary of Intel's Prescott processor in two sentences. However, is the Prescott a trendsetter?
In our opinion, the debut of a processor based on a cutting-edge process technology and architecture that only offers the same performance level as the predecessor is unanticipated. Despite 1 MB L2 cache and some optimizations, Prescott is slower than Northwood in roughly a third of our benchmarks. Software, like many 3D shooters and more serious applications like Lame, MS Movie Maker 2, Mathematica, Cinema 4D or even 3DStudio perform worse than before.
Not only that, Intel actually cancelled a major chip project because of falling revenues. And additionally, those scores are just plain depressing. The Northwood is actually faster then the Prescott in so many respects.. that's just depressing.
