Re: Pete's explanations aren't the whole story No, they don't include the bottom line: CPU speeds are increasing faster than memory bandwidth and latency is being improved, and P4 performance collapses as its clock speed moves ahead of memory system performance. Athlon and PIII can get very good performance with SDRAM, and performance improves somewhat as memory performance is improved. P4 needs dual channels of high bandwidth RDRAM to produce performance equal to that of Athlon on a single DDR channel. Drop memory subsystem performance down and Athlon loses about 15% of its performance while the long unbalanced pipeline of P4 produces a performance drop of nearly 50%! As CPU speeds from both companies jump ahead next year, the effect will be the same as matching either company's chip with a "low end" memory subsystem this year. P4 will go from looking iffy to clearly being awful.
