Fyo, Re: That leaves only frequency as the variable. Yeah, but you didn't concentrate on frequency, you looked primarily at Model ratings. It is quite clear that they can't scale as good as Northwood's clock-speed since the model/frequency ratio is getting larger with every new speed grade. The model rating formula model rating = clock-speed * 1.5 - 500 is approaching a model / Mhz ratio of 1.5 asymptotical. E.g. the XP1800+ had a model rating that was 17% faster than its clock-speed while the XP2100+ has a 21% gap. For every new speed grap this gap widens by about 1%. A XP3000+ had to be almost 30% faster than a Pentium 4 running at 3 GHz. That's just not realistic. My guess is that AMD will rework their model rating formula when Hammer is released. In the mean-time they will face serious pressure from Intel. Andreas
