Katmai benchmarks Business Winstone 99 Katmai/500/100 22.2 Pentium II/500/100 22.2 Looks like the extra 32K L1 cache doesn't do much for performance here. Quake II (3.19) (800x600) K6--2/400/100 56.4 Pentium II/500/100 56.0 Katmai/500/100 55.9 Pentium II/450/100 55.6 Pentium II/400/100 55.3 Interesting... 3D Winbench 99 Katmai/500/100 485 Pentium II/500/100 473 Pentium II/450/100 465 Pentium II/400/100 458 Pentium II/350/100 448 K6--2/400/100 439 Katmai is 2.5% faster than normal PII. Tests used the Null Device 3DWB99 (800x600) Katmai/500 2070 Pentium II/500 1770 K6--2/400 1120 Lighting & Transformation Katmai/500 63.3 Pentium II/500 36.3 K6--2/400 36.4 Transformation Katmai/500 85/1 Pentium II/500* 78.7 K6--2/400 58.2 I think the article implies the lighting and transformation test was done by the processor, basicaly, enhanced by KNI New CPU--Mark 32 (cycles/sec) Katmai/500/100 38.8 Pentium II/500/100 38.8 Pentium II/450/100 34.2 Pentium II/400/100 31.7 K6--2/400/100 29.9 Pentium II/350/100 27.9 Seems normal. Windows NT 4.0 Business Winstone 99 Pentium II/500/100 31.4 Katmai/500/100 31.2 Pentium II/450/100 29.5 Pentium II/400/100 28.3 Pentium II/350/100 26.3 K6--2/400/100 25.6 Again, looks like the extra L1 cache doesn't do much. The K6-3 should be able to put up a better showing. 3D Studio Max (sec) Katmai/500/100 76 Pentium II/500/100 76 Pentium II/450/100 85 Pentium II/400/100 95 Pentium II/350/100 109 K6--2/400/100 141 Raw FPU power of the PII show here. Conclusions? The extra L1 cache doesn't improve "Business" application performance. gamespot.co.uk
