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.
- coryfklein 9y agoI can't answer authoritatively, but I would speculate it has to do with the highly parallel nature of GPUs.
- Retric 9y agoYea, 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.
