You cant average with so many different speeds. 7 of the P4s are 2.53Ghz and higher. Only one AMD system is 2.5Ghz, and that is overclocked (there are no Athlon 2.5Ghz CPUs yet, the highest is the 3200+ @2.2Ghz). Something like this is a little more valid: AMD 2800+ (2.083Ghz) 1 Gb RAM Win 2000 Pro 192 seconds AMD 2.1Ghz 1 Gb RAM Win 2K 193 seconds P4 2.8Ghz 1 Gb RAM Win 2K 194 seconds. From those results, it looks like the AMD CPU is a good bit better than the P4 in Poser. It's 700-800Mhz slower yet still on top.
