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.

Latency, with 2 CPU sockets sharing info from socket to socket the data must be transmitted over the FSB. The same thing happens with the Intel Core 2 Quads as there are 2 dual core CPUs set in the same CPU die, giving you a dual socket solution in a single socket.

Now all AMD quads and the Intel i series quads are real quads, the cores are able to talk to one another directly without having to transmit the data over the FSB.
