For DIEP a celeron 300A at 450Mhz performs like a PII at 266Mhz. An alpha 633Mhz 21164 (using gnu-c compiler) performs like a PII at 360Mhz. Both i blame slow or small L2 cache size. >FRITZ MARK short 316 KN/sec=392 (16 Mb hash tables) > >FRITZ MARK long 291 KN/sec=434 (96Mb hash tables) > >JUNIOR MARK short 307 KN/sec=381 (20 mb hash tables) > >JUNIOR MARK long 332 Kn/sec 373 (96mb hash tables) I wonder how these values >compare with a genuine pentium ll 450 or 400 MHz or even a top of the line AMD >K6? would the extra 512 kb of cache running at 1/2 speed out perform 128 kb >running at full speed?
