AMD is working on a new Deneb-based Phenom II X4 975 core and judging from previous speed updates the new CPU might actually even work at 3.6GHz.

TDP's can be as high as 140W, but that will have to be tolerated for such a speed. We don’t know when AMD plans to launch this CPU, but it’s almost certain that it comes in the first half of 2010.

Once Phenom stepping three is available there might be a chance to make a 125W version of this CPU. The plans are in the pipe, and the good thing about it will be the price that will definitely sit close to €200,the current price of Phenom II X4 965.

We will let you know when Phenom II X4 975 comes closer to being launched.
