AMD has lost their edge. They used to compete with low priced processors that were pretty much matched, within a few percent, with Intel's offerings. With their newest flagship Bulldozer processors retailing at 279.00 you can save yourself $60.00 and go with the a Intel i5-2500k and have nearly the same performance. The AMDs may do well in highly multithreaded scenarios, but their single core performance isn't stellar.

Yea, they compensate by having twice the cores with each pair sharing a floating-point units, which works differently than Intel's HT used in Sandy Bridge. Basically which will be better depends on the workload.
