What is the best cpu's at present? Explain why. Pentium 4: + fast clock speed... that about all it got going for it + Hypertranport, 2 processor emulations, parrellel processing. - 20 step pipline very bad ~ 800Mhz 128bit non-direct memery bus Athlon 64 FX + 12-14 step pipeline can do more per cycle then p4 this is why a Athlon 64 at almost 1Gz less speed can still compete and even out compete the p4 in many calculations. + 64 bit complient, x86-64 + 800Mhz 128bit direct built on memory bus, lowest memory latency and highest memory efficiency + 6.4GB Hypertransport channel: Highly efficient and fast data bus to peripherals. G5 + Most efficnet pipeline + 64 bit complient +1GB 128bit non-direct memory bus, now when we have 500Mhz DDR this will be a major advatage. + 3.2GB Hypertransport channel: Highly efficient and fast data bus to peripherals. This is just the skim of the top people.
