Hardware, Embedded Systems Anyone contemplating a new computer purchase (for personal use or business) is confronted with new (and confusing) hardware choices. Intel and AMD have done their best to differentiate the x86 architecture as much as possible while retaining compatibility between the two CPUs, but the differences between the two are growing. One key differentiator is hyperthreading; Intel does it, AMD does not. This article explains what that really means, with particular attention to the way different server OSes take advantage (or don't). Plenty of meaty tech stuff.

I should probably add that while AMD's marketing department probably doesn't like "hyper-threading" (Intel's marketing), AMD's "Bulldozer" CPUs are planned to have something where 2 cores share some execution units to improve utilisation of those execution units. This will confuse things even more - the end result would be that a pair of AMD cores will behave a little bit like separate cores and a little bit like a single core with hyper-threading.

From what I understand of Bulldozer it only shares the floating point units. This would mean that the cores will perform like full cores until they are fpu constrained.
