This is what i mean, an alpha 2 processor is around $20000 in the store now. that's for a 833Mhz dual alpha. A dual 1.2Ghz K7 of course blows that away for DIEP. An alpha 633Mhz (21164) used to be for diep around the same speed like a PII at 380Mhz. And the PII was 17.3% faster than a PII the K7 is another 10% faster than a P3 the palomino i have now is another few % faster. 21264 has about the same number of registers as a K7, and the 21264 has huge costs for branch mispredictions. The 4 instructions a clock it sometimes can do hardly make up for the lack of 400Mhz in speed. And that for a factor of 10 in price difference... >-Tom
