Hello Friends.

I will have to buy a new grapcih car and i m trying to decided between 2080 Ti and 2070 Super.

At first view, 2070 SUPER looks good for price / performance

But when I examined features of two, some features 2080 Ti makes me think !

Because ;

2080 Ti 352 bit but 2070 SUPER 256 bit
2080 Ti RTX-OPS 76 T but 2070 SUPER 52 T
2080 Ti Giga Ray/sn 10 but 2070 SUPER 7
2080 Ti Giga Ray/sn 10 but 2070 SUPER 7
2080Ti Memory Bandwidth (GB / s) 616 GB/s 2070 SUPER 448

What does the features I mentioned above change in terms of rendering?

Does anyone have any experience in this regard?

Is it worth paying more and getting 2080 ti?

I think the best thing you can do is to compare the scores of each GPU on the Octane Benchmark. That way you'll see what kind of performance difference you can expect. Bandwidth, CUDA cores, Frequencies all work in tandem anyway so it can be a bit useless to focus on that for comparison purposes. What you are most interested in is how the GPU performs as a whole.

Typically you can calculate renders time pretty easily - say your render needs 1 hour to complete with a single 2080ti. An additional 2080ti will drop that down to about ~30 minutes. Now if you calculate how much of a difference in performance there is between a 2080ti and a 2070 you can then do the same :) Obviously these are rough calculations but in my experience pretty much totally reliable.

You should also think about your VRAM requirements. I work on product shots / arch-viz interiors and 11gb is kind of cutting it short as is - especially if you are using 4k, 8k textures and scanned models. Then again, you might be working on logos spinning around and you could probably be fine with the 2070 and its 8gb buffer :)
