In the fourth quarter of 2011, AMD will unveil new A-Series APUs in the socket FM1 package, these include not one (as reported back in July), but two models that come with unlocked base clock multipliers. Unlocked multipliers made overclocking significantly easier. While AMD won't use the "Black Edition" moniker, it will use the "K" extension. Incidentally, "K" stands for "black" in the CMYK colour model.

AMD's unlocked APUs include the A8-3870K and the A6-3670K, which are 100 MHz faster than the A8-3850 and A6-3650, respectively. With its four x86-64 cores clocked at 3.00 GHz, the A8-3870K features 400 stream processors running at 600 MHz on its Radeon GPU component, while the A6-3670K CPU cores are clocked at 2.70 GHz, and the chip has 320 stream processors running at 444 MHz. The two chips, however, will not feature TurboCore technology for the CPU cores.
