GPU Compute render perf review with 20 GPUs

We will not peek at game performance with graphics cards for a change, instead, we'll be firing of three GPGPU render compute solutions to see how they react towards the twenty graphics cards we fire off at them. What's the best GPU to use for GPU assisted content rendering?

From those results it appears to me the 2070 Super is the clear winner if you want to render using Blender. It is only 20% slower than faster 2080 Ti using the Optix API - and you can get it for 45% of price!
Cheapest 2080Ti is about £950, cheapest 2070 Super is £450... most expensive, fastest 2070 Super is still only £582 FFS!
Also an even closer 2080 Super or 2080 is still only the £650 area.
2080 ti should definitely be faster using Optix - it has 140% number of cores of 2080 Super and only 112% performance difference. Where did it lose the 28% difference??
Against 2070 Super it has 170% number of cores and only 120% difference in speed.

100% slower would be zero performance.
Not sure what to make of 120% less performance, does it undo work?

The 2070 Super is 120% while the 2080 Ti is 100% relative speed. It's obvious what I was talking about. So maybe its 20% slower then.

Why no Quadro's?

I know it's different but I transcoded a 3hr movie in H.264 4K HDR into H.265 once with only the cpu and then with NVENC on a 1080ti and the fps pretty much doubled
would be great to have 1 "gaming" and 1 "hedt" cpus just to see the giant trench between gpu and cpu processing
Hi there
Not sure if would compare CPU vs GPU in video editing or video rendering
I think Linus and few others done such tests while back
Hope this helps
Thanks, Jura
