My results on AMD 3000+ mobile 2189 Mhz (11 MHz underclocked) for comparison: >Fritz8 mark 1182 -> 1542 = 30% gain >Fritz8 knps 1065 -> 1194 = 12% gain 1104 (8.023) >Hiracs8 mark 790 -> 923 = 17% gain >Hiarcs knps 236 -> 275 = 17% gain >Shredder8 mark 1392 -> 2784 = 100% gain >Shredder8 knps 301 -> 420 = 40% gain 356 Now look at the price/performance ratio. > >I have no explanation for why the "mark" number for Shredder and Fritz increased >so much more than the knps, but I would love to know. Forget about the mark numbers. They were always crap.
