I was just over @ Overclockers.com and I see they have a new article posted called Hyp(er)ing A Benchmark! I suggest you give it a read as the only benchmark that can test Hyperthreading is optimized to the gills for it as they put it.
Coincidentally (or not), hyperthreading will put PIV Sandra scores significantly above AMD's Sandra scores. At 3.06GHz with HT, well, see for yourself. To match it, an XP would have to run at over 2.5GHz to match the ALU and forget about the SSE2 FPU. Apparently, this boost will only be available for Intel chipsets. Hyp(er)ing A Benchmark
