According to one of our sources, the next AMD's APU Bristol Ridge could have a 16CU GPU (the same Radeon HD7850's CU), doubling the Compute Units that we have seen in Kaveri/Godavari APUs.

 

 

Thanks to the high density 28nm node of GloFo will be possibile to integrate 16CU in the next GPU, but the problem will be the available bandwidth. Despite Bristol Ridge will use a Dual Channel DDR4 memory controller, the Bandwidth will be equal to 50GB/s at most. In any case, the performances of this kind of GPU will double the performances of Godavari GPU.
