Someone ban the knucklehead plz. Enough is enough.

To me Navi looks like Maxwell when it hit. For Nvidia it totally changed their standings to a clear dominant position - Navi or RNDA may do the same for AMD.

The perf/watt edge still goes to Nvidia Turing for the most part and that is on a 12nm process but a much larger die. AMD could have traded some die space as in larger to up the clocks some which larger die would allow better cooling. With a better power budget allows NVidia to make a chip as big as needed to be to maintain top performance. Memory bandwidth looks like AMD could improve upon for more performance, faster DDR 6, wider bus etc. Slow down Navi GPU a little but increase memory bandwidth and the Perf/Watt should improve.It may, but it is still an uphill battle for AMD as Nvidia won't just set around like Intel. The big if at the moment is we just don't know how big of an upgrade when Nvidia release Ampere. Recent history have shown whenever Nvidia changes process node, there is a big increase in performance for them.

I still think there is a lot of maturing yet for Navi for developers and even in the drivers - so 5%-10% is probably not unreasonable here. My sample undervolts well too, so once process maturity occurs, the voltage and thus power will most likely be lowered for Navi in general. With AMD what seems like unneeded overvolted GPU's hints at AMD accepting lower quality chips to be accepted that need the higher voltage to work in spec. Better binning and skews, Nvidia had A silicon for Turing faster parts (think they got rid of that now because of process maturity) allowed slower spec ones to still be sold while AMD appears to bin less and rely on higher voltages to ensure they work.
Yes in the GPU space, uphill battle against Nvidia but also Intel is like waking up a sleeping giant. All in all we all benefit when both companies are competing fiercely against each other.
