RTX vs GTX, there is some speed comparasion?

[info]

Hi, I have a GTX 1080 and before upgrade to a RTX 2080 will be nice have some speed comparasion.

I think that can be useful for a lot of people.

use the vray bench. its a good indicator.

Did a test with 2080 TI vs 1080, rendering 500 frame at 9 AA samples. 262 min vs 532 min, so it gives you pretty much exactly 2x the performance.

I just did some quick testing, between 1070 TI vs 2080 TI it's about 2x perferormance. 1:05 vs 2:24 on a simple 4K render. The difference was less for HD, but don't have the numbers now. Also 2080 TI gives about the same performance as a 2990WX Threadripper, but you have to render using IPR.

I don't know the best way to present a comparison as there are a lot of variables at play.
Example using the 1070: https://twitter.com/Lucas_3D/status/111378151349608857
