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.

4 * 6 = 24
Just as, I wouldn't call 2x A64 FX 74 on a L1N64 SLI-WS a four core CPU.
i know intel does
12 cores = great for encoding ripping benching Multi tasking etc..
12 cores = Fast cpu for the Future if software ever catches up..
minus -
12 cores = Pointless for gaming..
12 cores = limited overclocking..
12 cores = pricey..
Some others from Asus, MSI, and Supermicro:
Don't know if Vantage will be threaded enough for a system like this to overcome an overclockable Skulltrail/Asus Z7S setup, but I'd have some fun trying if my numbers came in :D
Plus, because of the lack of Barcelona Opterons for the last couple months prices of the Tyan and Supermicro boards have dropped from ~$1800 to under $1000. I was just looking at eBay and there's a Tyan that's at $650 right now.
For the more demanding of 3D animators, could do up a 4P Opteron/QuadroFX 4700X2 system for under $10K.
every cpu is technically bugged due to erratta, Intel was selling the P4 despite heavy Errata due to Netburst- so many L2 misses- had to repeat thru the pipes.
But Phenom/Barcelona was %50 faster than core2duo at the same clockspeeds
when you were to believe AMD pressreleases. So I take it all with a grain of salt.
But if AMD pulls it out, I'll take the ticket to Istanbul.
