For a good while now, we've known AMD is cooking up six-core desktop processors code-named Thuban and officially branded Phenom II X6. The rumor mill even gave us some model numbers and a launch date (April 26) last month, but specifications have thus far eluded us.
Luckily, TC Magazine now reports that a pair of Gigabyte BIOS updates have revealed the clock speeds of three Phenom II X6 processors claimed to be in AMD's roadmap. If that information is correct, the Phenom II X6 1035T will run at 2.6GHz, the Phenom II X6 1055T will tick away at 2.8GHz, and the fastest of the three, the Phenom II X6 1075T, should hit 3GHz.
Other specifications will include 9MB of L3 cache, thermal envelopes in the 95-125W range, and Socket AM3 packages—so, these puppies may well work in existing motherboards.
TC Magazine makes no mention of that Turbo Boost-like feature we first heard about over a month ago, however. Assuming that information was correct, Phenom II X6 CPUs will be able to "overclock" individual cores and shut the other ones off in applications that require more single- or dual-threaded brawn than anything. If it indeed has a base clock speed of 2.6GHz, the Phenom II X6 1035T may otherwise have trouble keeping up with its Intel rivals, not to mention quad-core Phenom IIs that now reach up to 3.4GHz.
