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.

is that chip manufacturers are selling us products that are over engineered for most our needs. Most OS's, and applications aren't written to "really" take advantage of multiple processors, let alone identify and adjust performance for the number of cores present. I chuckle when i hear some guy at a client site talking about buying the newest Core i7 chip running at 3GHz blah blah, so I ask, what are you doing with it, and he says, "gaming man, gaming." All the power in the world, and we game. Gotta love it.

Thing is most games struggle to use more then 2 cores, the extra performance gained is from the larger pools of L2 and L3 cache on the higher cored CPUs.

The major dev houses need to step up to the plate, but are unlikely to as it require more then the bare minimum to get their devs to hammer out barely working code on a nigh impossible deadline.

OSS has fared better, but there is still a long way to go before everything divides up the workload as much as possible.

there are already 12 core CPUs out from AMD for servers, by next year they will be in the desktop. The software just isn't keeping up.

Hardware leads Software, not the other way around.
