12-core CPUs From AMD on Their Way
Shanghai, the 45nm core from AMD, is likely to debut late this year. It will be similar in many aspects to the currently-availabe B3 stepping of the Socket 1207 Opteron (Barcelona) shipping today. Unlike Barcelona however, which has its HyperTransport 3.0 clock generator fused off, Shangai should utilize HyperTransport 3.0 for inter-CPU communication. Also, AMD has a new "native six-core" Shanghai derivative in store, currently codenamed Istanbul. This processor is clearly targeted at Intel's recently announced six-core, 45nm Dunnington processor. AMD plans to utilize 2 Istanbul cores to create a 12-core CPU, where both cores will communicate with each other via HyperTransport 3.0. A quad-channel memory controller may also be possible. All new Shanghai CPUs should be backwards compatible with existing Socket 1207 motherboards.
Shanghai is currently taped out and running Windows at AMD.

I just like that the difference is huge even with a significantly lesser processor.... and a cheaper build of a platform by probably $100.
They may be falling on hard times in terms of CPUs, but AMD has a strong graphics division and with the launch of the 7x0 series chipsets, really has the edge here. Sure the P35, P45, X38, and X48 are no slouch, but especially with the overdrive utility, I think AMD has the edge.

2 cores = 4 threads
4 cores = 8 threads
8 cores = 16 threads
16cores = 32threads
32 cores = 64threads
Hyperthreading is so lovly :P
Asides, I'm glad to hear this kind of news from AMD - nice to know that they have been up to something, and it looks like they're gearing up for a battle-royale with Intel within the next few years.
on the fire demo of nehalem it showed some great work
:shiftyeyes:
:)
12 cores per P, 4P per blade, 10 blades per 7U chassis, 6 chassis per 42U rack... 2880 cores!
Though my company runs fine on a handful of 2P servers, so I'm not going to see anything like that :D

that's like saying since THoroughbred A didn't OC worth crapso the next AMD won't oc worth crap. Then the next revision was Thoroughbred B and the next core released was Barton, both of which were OC animals.
