Damn! Is it really only 30%? I thought it was in the 50%/60% range... I guess I need to review this thread again, I obviously missed something.

Either way, I've got a launch 1080 so the gains are going to be big for me no matter what...

3080 is ~40-60% faster than the 2080ti in RT loads. So if you’re upgrading for RT it puts you in a very good place FPS wise. The 2080ti felt borderline at times. An extra 50% is substantial.

Id put the 3080 over the 2080ti at closer to a 25% improvement, and the 3090 (24gb) over 3080 (10gb) at a 5% improvement...but math is hard https://www.techpowerup.com/review/evga-geforce-rtx-3080-ftw3-ultra/28.html

The 3080/3090 looks less impressive to the 2080 Ti once compare apples to apples, either comparing all three cards OC or comparing them at a fixed (say 250w) power limit. In that case the averages sort of hash out more to 27% and 8% ish improvements.

As others have mentioned, it depends on what resolution you are referring to. Also, percentages don't always tell the whole story. The higher the framerate, the greater the fps increase with smaller percentage increases (10% of 60fps is 6 fps while 10% of 100 fps is 10 fps, yet a 6% increase of 100fps is 6 fps). When comparing the stock 2080 Ti average frame rates to a stock 3080 and 3090:

At 1080p:
  • 3080 is 17.75% faster (28.4 fps).
  • 3090 is 22.88% faster (36.6 fps).
  • The 3090 is 4.35% faster than the 3080 (8.2 fps).
At 1440p:
  • 3080 is 24.98% faster (31 fps).
  • 3090 is 33.04% faster (41 fps).
  • The 3090 is 6.45% faster than the 3080 (10 fps).
At 2160p:
  • 3080 is 31.98% faster (23.6 fps).
  • 3090 is 44.58% faster (32.9 fps).
  • The 3090 is 9.55% faster than the 3080 (9.3 fps).

the 3080 is semi-vaporware...if most people have to wait until February/March of 2021 then it makes more sense to just wait for the inevitable Super refresh versions

Could be. Wouldn't surprise me to see Hopper on TSMC 5nm in about 18 months. Whether that is just HPC/AI or consumer your guess is as good as mine.

18 months is in the realm of a normal lifecycle for a video card generation.

Yeah, pretty much. I don't expect anything drastic.

Some people were floating rumors that Hopper would be within a year of Ampere (Q3'21?). I don't see it. I'm still betting on the "Super" refresh on 7nm TSMC with higher clocks and more memory. I would think that could be as early as Q2'21 though.

I think we will see Hopper much, much sooner. I wouldn’t be surprised if we see it late summer/early fall 2021. I think that the cancellation of the 3070 and 3080 refreshes with larger memory configurations could be indicative of that.

It’s becoming more evident that Nvidia is having yield issues with Samsung causing the supply shortages and not the BS artificial shortage conspiracy theory made up by MLID. If Nvidia can’t produce cards they’re going to both lose market share and revenue. And this shortage is coming at the worst time when AMD appears like it will be competitive on all performance tiers for the first time in what...3 generations?

They’re going to want to accelerate Hopper as quickly as possible to get on TSMC’s 5nm, and get revenue back up and retain its market share.

TsMC 5nm is mega expensive, limited capacity and unavailable (Apple). Even 7nm TSMC is significantly more expensive than Samsung 8nm but supply is opening up with Apple moving and AMD working on it for post-Ryzen 5000 chips. I’d say 7nm is more likely, but I do wonder if it will come with a price bump.
