Fifty or Sixty Years of Processor Development for This?

How are GPUs still apparently increasing their power exponentially without using more power? It looks like the best 10 series NVIDIA GPU has about twice the power of the best 9 series, about 2 years earlier, which lines up with Moore's Law pretty closely. How are they doing it? Maybe they were actually lagging Intel- looks like the 9 series was a 28nm process, and the 10 series is a 14 or 16nm process.

Yea, GPU's are a few nodes behind which means they will take longer to hit the same wall. Even the GTX 1080 Ti just hit 16nm.

Compare a 95 W (22nm) i7 2600k from January 2011 vs 65 W (14nm) Core i7-8706G from February 2018, that's over 7 years of progress for 30% lower power consumption and a fair speed boost.

That's what GPU's are facing starting now, though they can directly trade lower power consumption for more speed as they are embarrassingly parallel.

I can't answer authoritatively, but I would speculate it has to do with the highly parallel nature of GPUs.
