AMD Radeon Navi GPU

Some Information.
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
View attachment 434216
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.

in DaVinci score means FPS, the higher the better
in FCPX score is time, the lower the better

Do you have BruceX times for R-VII on your machine?
any glitches with 5700XT such as export to h264 or h265 or acceleration of such material?
Tx for the bench!
 
Upgraded to Catalina 10.15.1 with the Powercolor 5700XT Red Devil installed, used the agpdmod=pikera in boot args and changed the SMBIOS to iMacPro1,1 in order to boot. Was using iMac14,2 before and it would only boot halfway and then a black screen. Looking good so far.

Edit:Forgot to mention I'm using the HDMI port.

Got Powercolor 5700xt red dragon running on my sandy bridge setup. Switched from 980ti. Was running High Sierra. Pulled the 980ti, switched to my natively supported 680, uninstalled CUDA and Nvidia drivers. Upgraded straight to Catalina(no issues), installed the latest lilu and weg, had to use boot argument agpdmod=pikera and it booted right up. Using top display port, 1440 monitor. started and ended with iMac 14.2. H264/265 doesn’t seem to be supported(wasn’t on my 980ti either). Does anyone know if the issue is because I’m running sandy bridge or do I just need to change the smbios to iMac Pro.

Thanks for the help guys.

Try changing to MAcPro 5.1, 6.1 or iMacPro 1.1
 
@mythamp Thanks, indeed it appears to be working after installation. I didn't use tabs and spacebar, I've installed macOS on my SSD using my MacBook via USB enclosure, and then inserted it back to M.2 slot, and it booted fine without any display glitches.

Results are in FPS .... it's the unit for the Candle Project ;-)

I will soon ... because I need to unplugged the 5700 XT from the motherboard. Final Cut Pro X has very hard times with 2 different GPUs ....
any glitches with 5700XT such as export to h264 or h265 or acceleration of such material?
Glitches on the screen during the export, or in the exported h264/h265 file ?
I will test again
No glitches at all with R VII! it's expensive, but powerful, stable, easy to use and not so big in the case (easier dual GPU).

Keep in mind that : With Resolve 8GB of VRAM is recommended for 4K media and project and.... so if you want to confortable with bigger resolution .....
Final Cut Pro X need less VRAM than Resolve ...

Any glitches/problems with 5700 XT in FCPX, mostly during export (H/W acceleration is/not working, green stripes, etc.)?
