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.

Exactly. Hyper-Threading does give a performance boost if the application is designed to take advantage of it.

On an Atom-330 (Dual Core 1.6GHz), Hyper-Threading gives a 20% performance boost from our testing.
