If you compare a 1GHz Pentium 3 to a 1GHz Pentium 4, the P3 kills the P4 too. So there's no reason to buy a P4 instead of a P3, right? >Intel jacks up their numbers to get people to buy their product, which makes >them seem rather snake like.

They designed a processor with a certain target clock speed and a certain target "efficiency" (instructions per cycle) because they thought these targets would yield the best performance given process and cost constraints. There's no evidence that Intel artifically raised their clock speed target at the cost of performance in order to "dupe" consumers. Just because AMD designed their chips with different clock speed & efficiency targets doesn't mean AMD is somehow better or more honorable--in fact, given similar processes, Intel slightly outperforms AMD in general. In order to increase performance for Opteron/Athlon 64, AMD found it necessary to add 2 pipeline stages in order to run at higher clock speeds. Does that mean AMD is also "jacking up their numbers"? Do you think that AMD is trying to fool consumers, and it's just a coincidence that the new processors perform better? Also, I never heard any promises from Intel about 25GHz processors. If a drug company announced a new technique for designing anti-viral drugs and says that it "may" be able to cure AIDS by 2005, are you going to get all pissed off if that doesn't happen, either? -Tom
