What “current numbers” do you refer to? Of course it may depend on workload, but the 3080 has, at least in one benchmark[1], better performance per watt than all compared cards (7% better than 2080 Ti, 21% than 2070, 32% than 2080, 67% than 1080 Ti). Total power consumption is up quite a bit (25% over 2080 Ti), but still get more performance than more power.
NVIDIA pushed the 3080's stock performance a little too high up the perf/watt curve. If you limit it to the TDP of the 2080 Ti, you lose 4% performance but you get much better efficiency: https://www.computerbase.de/2020-09/geforce-rtx-3080-test/6/
It’s not clear yet, since we’ve no idea if there will be a 3080 Ti. The 3090 throws out the naming convention from the past few generations, leaving it a bit of a mystery. Nvidia may do as they did with the 1080 Ti: not release till nearly a year after the 1080 (whereas 2080 & 2080 Ti were launched just a week apart).
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.
This is actually what I find extremely dishonest (which is, in other words, extremely good marketing) - a lot of websites are comparing the 3080 with the 2080, and reporting massive improvements... which doesn't make much sense.
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).
