The 22G variant or RTX 5-8k are definitely better deal in terms of vram; the int8 or tensor performance is small price to pay for capacity.
In terms of performance in int8 in nv cards its almost always 4xfp32 since volta if i recall correctly - tho it doesn't scale that well in reality, Titan V only produced 3.9x fp32 when you disabled ecc on vram with ecc it was more of a 3.4x rendering it slower than 2080.
While Titan V is weak, 2080/Ti is weaker in out of the box in terms of time ~ but the difference is couple seconds at most.
If one is looking for fp16, int8 the 3080 is much better, and cheap option the performance is so much greater making both Titan V or 2080 just outdated retro-ware - nice cards to hang on the wall.
(same when you compare it to 7900xtx it just blows things out of the water as long as there's some support for amd, the language models i tested few days ago
LM Studio - Discover and run local LLMs ~ i was quite surprised at performance, i ran similar models on 3080ti a year ago and it was taking like 1.2sec per response, so i was stunned since 7900xtx it was instantaneous - if i ever go into it again i may write up my results for 3080ti and 7900xtx/or and if i get 40 series or some other gpu - for now i have too many.)
