Even as there are rumors that the launch of Opteron processors based on the Bulldozer architecture is imminent, there is news that AMD has rescheduled the launch of its FX series performance desktop processors to October 2011, sources told X-bit Labs. The reasons for the delay are known, but when the processors do come out, AMD wants to make sure that they target as many performance price-points as possible, and so the first wave of FX processors will include 7 models, that's four 8-core FX-8000 series chips, one 6-core FX-6000 series chip, and two 4-core FX-4000 series chips.

The first wave is going to include the 3.60 GHz FX-8150, the 3.10 GHz FX-8120 that will be available in 95W and 125W variants, and 2.80 GHz FX-8100 eight-core models; 3.30 GHz FX-6100 six-core model; 4.20 GHz FX-4170 and 3.60 GHz FX-4100 quad-core chips. As you can see, AMD does seem to have tweaked the clock speeds of some of the models compared to older clock speed tables by other sources. The next wave of FX series processors is slated for Q1 2012, which includes faster models across the three lines. According to data compiled by X-bit Labs, the FX series can now be tabulated as shown below.
