The AMD A6-6400K is a desktop APU from the Richland series. The chip is produced in a 32nm process and integrates 1 module with 2 CPU cores clocked at 3.9 to 4.1 GHz. Furthermore, the 6400K has a Radeon HD 8470D graphics unit and a DDR3-1600 memory controller.
The CPU cores are based on a reworked Bulldozer architecture called Piledriver. Although marketed as a Dual-core processor, the A6-6400K includes only one module with two integer-cores and one floating-point unit in total. As a result, the CPU is not a true dual-core processor.
The CPU performance of the A6-6400K is about on a level of a 2.2 to 2.4 GHz Pentium processor of the Sandy Bridge generation.
The integrated DirectX 11-compatible Radeon HD 8470D offers only 192 of the 384 shader cores of the Richland chip and a core clock of 800 MHz with no Turbo support.
The power consumption of the entire desktop APU is rated at 65 Watts.
