We don’t have many details, but we can confirm that AMD plans to launch two six-core desktop CPUs next year. This should happen in Q2 2010 and if AMD holds on to this date, it might come a bit later than Intel’s Core i7 980X.
AMD’s six-core 45nm part is codenamed Thuban and it comes
with 6MB L3 cache, C-state performance boost as well as DDR3 1333MHz support. As we said before, it supports AM3 motherboards and it should work in most existing models.
We don’t have any specifics about the clocks or what will be
difference between these two SKUs, but we can confirm that they are planned.
