The difference between M7 and G5 on a P200 MMX is also 16 >points. On identical hardware, we can therefore assume that the rating >difference between M7 and G3 is around 32 points. When you give G3 a 50% >speed advantage, your result is not at all unexpected. >Tord 1) The gain of 70pts between P90 and MMX200 for Genius5 is not necessarily to transfer to Genius3. For Genius3 the step from 486/66 to P90 is factor 2 but less than 60 points so what can we expect from another 2x speed P90->P200MMX? 2) I am not sure in how far 50% speed advantage would influence your 32pts difference. 2482 is the value for MCP8, so do you expect Genius3 winning higher against MCP8 because this is less than 2512 for MCP7? I don't. Anyway, see other mail, it shows that indeed "old" programs are still on top running on fast hardware! (at least Genius3 :-))
