I plugged both a Radeon VII and an RX 5700 XT on the motherboard: System info show both use x16 PCIe
I made several quick tests with DAVINCI and the "candle project"
Display is 3440x1440 via DP

What I learn :
1 - RX 5700 XT in a little less powerful than Radeon VII ➧ RX 5700 XT has better price/performance ratio
2 - OpenCl is dead .... slow
3 - Pluging the display on computing GPU has a minor impact on performances (It's not true with RED RAW GPU debayering for example)
4 - I can't figure how Final Cut Pro 10.4.7 select the GPU despite the new preference menu
5 - RX 5700 XT (Gigabyte Gaming OC) is less noisy than the Radeon VII when fully loaded
6 - RX 5700 XT (Gigabyte Gaming OC) is a little wider than 2 PCI slot ➧ multiple GPU difficulties
After I Superscale (very GPU intensive) the media to 8K and make the project to 8K, to find a if the RADEON VII's 16G is an advantage. 2 TNR Test give the same result with each computing GPU
Hope this helps
Hum. I think I might be misunderstanding the results in your table. Aren't the times actually lower using OpenCL? And in some cases I see lower times for the 5700XT than the Radeon VII's. Or are those last two columns not times (so, not better performance for lower score)?
Thanks for letting everyone know the results of your benchmarking, I have been looking for this kind of information for quite some time.
