Imo 3090 is more than enough for personal use. For dense DL research, one 3090ti card won’t have visible difference than one 3090. Also 3090ti requires much higher total power supply(~1000 vs 3090: ~800).

3090/ 3090ti Definitely worth the update

Without a doubt. You get more than double the VRAM (11GB -> 24GB), and you get tensor cores which are significantly faster, and also half-precision tricks give you effectively double VRAM again compared to FP32. A 3090 (possibly Ti) can train the kinds of models you used to train on 4x1080Ti.

Go for the 3090 unless they're the same price. The 3090Ti is slightly more performant, from our benchmarks up to 10-15% in training, but it generates much more heat and noise, and consumes way more power.

thank you so much for the reply!

I think I'll get the 3090ti still just because it's on sale where I am at the moment. Gonna take your advice and go for it :)

right! thank you. Yeah strangely enough they're the same price as the 3090ti is on sale - do you think a liquid cooled (AIO) one will relieve some of the heat and noise issues?

yes the VRAM jump is one of the biggest reasons why I am considering the upgrade!

4 x1080ti - that is certainly too tempting

Thanks!
