Kevin and Paul, the reason why I asked about Dixon and mobile K6-3 power consumption is that laptop owners care just as much about power consumption as they do about performance. I was told by someone that the K6-3 will consume less power than the Dixon. I wonder if this statement is based on an invalid comparison, because although Dixon's die is larger and more power-hungry, the elimination of the off-chip L2 cache helps to decrease overall power consumption. Meanwhile, a K6-3 has to run on a 100 MHz bus, but if that bus only consumes a half-watt more than a 66 MHz bus, it really doesn't matter. By the way, just for your info, Intel's own Business Winstone 99 benchmarks put the Dixon at approx. a 5% to 7% advantage over a mobile Deschutes w/ 512K of off-chip L2 cache. A K6-3 without an L3 cache is about 3% faster than a Pentium II (Deschutes). Seems like if the mobile K6-3 wants to compete against Dixon in performance, AMD will have to add L3 cache. How much power does a motherboard SRAM cache consume, anyway? Tenchusatsu Tenchusatsu
