I have one p4 1800mhz sitting here, one amd 1.4ghz both has sdram 133mhz, the p4 is way slower than the amd, even the ram BW is lower, though the p4 has 400mhz fsb... While the athlon has only 266. That tells something about how crappy those p4 chips is. I bet if i was able too clock an k6 too 1800mhz it would outperform the poor p4
