X2 and Core2 Duo are rivals, but not the same...not really sure about performance characteristics of either. X2s are cheaper, but - best to my knowledge - generally underperform similarly clocked c2ds in most applications.
If I'm wrong, gimme some real evidence to chew up!
X2's are about 30% less efficient that core 2 duo's, clock for clock, according to the benchmarks I've gandered at. Shorter pipes, higher IPC, a generally superior core architecture.
