AMD Radeon R6 M255DX
The AMD Radeon R7 M255DX is a Hybrid Crossfire combination of the integrated Kaveri Radeon R5 (in the A10-7300 or A8-7100 APU e.g.) and a dedicated Radeon R57 M230, M230X, or M255 (called Dual Graphics - DX). Both graphics cards use the AFR mode (alternate frame rendering) to each render a frame. Around 30 fps this Dual Graphics combination may suffer from micro stuttering due to different frame latencies.
The performance depends on the driver support for the used game. In some cases the game engine will only use the dedicated graphics card and therefore the M255DX may not be faster than e.g. a M230 alone. The other end of the spectrum some games like Tomb Raider achieve significant higher fps rates. However, there are some games where Dual Graphics is even slower than with disabled settings, so the user might need to test the settings out.
The shaders of both GPUs can be used for OpenCL calculations and therefore make use of both GPUs.
Furthermore, the M255DX supports Mantle, Eyefinity and Enduro to in battery mode (use of the integrated GPU alone).
The maximum power consumption can be quite high using Dual-Graphics as both GPUs of the APU and the dedicated graphics card are running.
