I've been thinking a bit about how MS got to 6TF. It wasn't how I expected, I expected something like 64 CU's at ~900mhz since we've all been conditioned to expect low console clocks.
It occurs to me maybe this was about cost? By going with a narrower GPU clocked high, you save on die size. You also take a hit on yields.
You'd think you then pay more for cooling possibly canceling out the benefit, but I wonder if you end up netting savings. 360mm^2 die seems pretty svelte.
Or I wonder if it was more driven by AMD not sure they would have more than ~40 CU's parts available in time for 2017 launch?
Just difficult to say all around. The apparent lack of Vega is puzzling.
Maybe Microsoft have more confidence/expertise in hardware now?
I mean look at the components. The build quality seems pretty good for a console...
