At Hot Chips this past week, AMD unveiled more details of the upcoming 12-core "Magny-Cours" processor that it hopes will help it stay competitive in the server game. Due in 2010 on AMD's 45nm SOI process, Magny-Cours uses the same basic core microarchitecture as the current Shanghai quad-core server processor, so if there's any improvement in per-thread performance it will have to come from better system design.
The basic idea behind Magny-Cours is simple: take two six-core Istanbul processors, downclock them a bit to reduce power, and squeeze them into a multichip module (MCM) so that they can fit into a single socket. By using an MCM, AMD will be able to fit 12 cores into the same thermal and power envelope as Istanbul.

I wonder how many years it will take before we see 64 cores on the desktop and maybe 32 cores on a laptop? This reminds me of razorblades....first we had one blade, then two...now we have five....how long before we have ten blades in those?
