Depends on a few factors IMO: 1. AMDs willingness to embrace the same price points 2. The vagaries of TSMCs 20nm process. Wafer cost is supposed to be significantly higher than that of 28nm and 40nm. Yield makes it even more of a crapshoot, especially if AMD look at competing with Nvidia's large die (or large die + ARM) 3. Does AFR become more refined than the basketcase it is at present. If developments in frame metering and buffer switching make mGPU more attractive then the gulf in pricing (esp versus performance) between the single high-end GPU and two midrange cards will only serve to erode the high end market.
