Joshua, Those benchmarks are quite interesting and I wonder if I interpret them at all correctly. It would seem that the Intel outperforms it's advantage in clockspeed (1/6th faster, but ballpark 1/3 better performance?) so the question would be performance gain per dollar cost (which is fine); however, for that heart simulation towards the end, it looks like the AMD scales up with increasing nodecount enormously better, and with several nodes actually outperforms the faster Intel. Should I guess at relatively poor performance of the networking on the motherboard used with the intel chip or does that have anything to do with the CPU itself? Of course I myself am not much of an electronics geek. All I know is that copper is porous and electrons are reallly, really tiny billiard balls, but I don't understand where the cue stick is at all.
