David - excellent video and article. You deserve much respect as usual..

In your estimation - if there were an 'incompatible situation' for this type of rendering/rasterization, could the drivers switch Maxwell back to the 'traditional PC mode' for output? If yes, any idea of what kind of performance hit?.

Could this explain why Polaris hasn't caught up with Pascal on the perf/watt efficiency curve, despite the "in theory" advantage of Samsung/GloFo's 14nm process over TSMC's 16nm? (as evidenced by the Apple A9 that is slightly smaller and lower power on the Samsung 14nm process).

Thanks!
