Last week the DailyTech reported that AMD is talking about developments that will lead first to six-core processors, followed by a twin-die package that will put 12 cores in a socket
The first breadcrumb comes with a new “native six-core” Shanghai derivative, currently codenamed Istanbul. This processor is clearly targeted at Intel’s recently announced six-core, 45nm Dunnington processor.
… Two separate reports sent to DailyTech from AMD partners indicate that Shanghai and its derivatives will also get twin-die per package treatment.
…A twin-die Istanbul processor could enable 12 cores in a single package. Each of these cores will communicate to each other via the now-enabled HT3.0 interconnect on the processor.
