Individual cores will be able to hit up to 3.6GHz thanks to Turbo Boost, while Hyper-Threading support will allow it to juggle 12 threads in total. TDP remains constant at 130W helped by the newer fabrication process. The LGA 1366 chip will be able to drop straight into existing X58 motherboards, following a BIOS update, and should replace the Core i7 975 this March as Intel's flagship desktop product -- at the same $999 price point.
AMD's six-core Thuban processor is expected to hit around the same time as the Core i7 980X. However, in terms of performance, they are expected to compete for a completely different market, perhaps taking on Intel's Lynnfield Core i5 and i7 quad core CPUs.
