But slightly disappointing, hence hopefully an impure comparison. With default settings, but almost same node counts, I get: 37.8 AMD K7 Thunderbird 1333 MHz 27.1 AMD XP2200 Thoroughbred 1800 MHz I'd expect your Barton2500@1833 compared to my Thoro2200@1800 to perform somewhere between 1833/1800 and 2500/2200. On the bright side, this shows there's nothing to be ashamed of when confusing AMD ratings with AMD MHzs. Since they both are meaningless, being confused is the only sane option! ... Johan
