Not all 6000+'s have the same TDP. Maybe you have an F3 stepping 6000+ which has an 89W TDP, lower than a quad core Phenom (which is 95W only AFAICT). Doesn't really explain the power gulf, though. -- Cheers, Alistair. 137/1 Warrender Park Road, Edinburgh, UK. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
