I could never test the 21264 so far, only the 21164. 633Mhz 21164 is as fast as a PII at 380Mhz for DIEP. that was with the gcc compiler however which is inferior to the DEC compiler by a large margin (i have no idea how much, 20%?). However where 21164 had only 8kb L1 cache, PII has 32kb L1, 21264 has 128kb L1 and a new and very advanced branch prediction strategy and not 3 but 4 instructions a clock. So obviously 21264 is already 33% faster in advance because of the extra instruction. Add to that more for better branch prediction etcetera. Perhaps 2.0x as fast as a PII. Note that PIII is 17% faster for DIEP as a PII, so also there are big advances. >Uri
