I wonder how the 3070 and 3060 are going to compare, in terms of performance per watt, when compared to the 2080/2070 series. Based on the current numbers, they'll possibly show very little improvement.
Is 3080 vs. 2080 Ti the correct comparison?
Given the 3090 is not too much faster than 3080, it seems there may not be room there. But then again, the 1080 Ti was as fast as the Titan X. So…yea.
I think 3080 vs 2080 Ti is the only possible comparison, but websites should make it very clear that it's an unfair comparison.
Probably the only comparison that actually makes sense is the (future) 3070 vs 2080 Ti. I'm not suprised that Nvidia pushed the release (it was supposed to be released earlier).
Algorithmic improvements, custom domain specific ASICs, and maybe quantum computing or other physical processes in the future are where large efficiency deltas might come, but for now small improvements are here to stay for all chip makers.
>Wong, who is vice president of corporate research at Taiwan Semiconductor Manufacturing Corp, gave a presentation at the recent Hot Chips conference where he claimed that not only is Moore’s Law alive and well, but with the right bag of technology tricks it will remain viable for the next three decades.
“It’s not dead,” he told the Hot Chips attendees. It’s not slowing down. It’s not even sick.”

In fact, multiple gates can be created in the same transistor, in an effect SFN calls “multi-tunnel.” Multiple NOR and OR gates can thus be created from a single Bizen transistor, allowing creation of logic circuits with many fewer devices. This can result in a three-fold increase in gate density with a corresponding reduction in die size for integrated circuits based on the transistors. Summerland said that SFN is also creating a reduced device count processor architecture to enable analogue computing with Bizen transistors.
What makes sense to accelerate, how to integrate it and balance accelerators vs. general cpus, and how to expose it all to the programmer all seem like fun and interesting problems.
The 2xxx series wasn't terribly impressive to many so they've just started to peak out in the way that Intel did at least 5 years ago. We're heading into AMD's 4th iteration of processors that basically mop the floor with Intel from a price/performance and performance/watt standpoint and it's just starting to become accepted in the mainstream that Intel is in trouble. It will take another generation or two of products before the press catches on to the fact that what nVidia is telling everyone isn't true. Of course it will be helpful if there's some competition to point to that helps make the case.
