Radeon VII vs RX 5700 XT

Hardware and Software

All the tests use DaVinci Resolve Studio 16.1.1
I use the Candle Project
The results are in “fps” (frame per second)

Hack X299 SAGE 10G – Core i9 14 cores 3.1 Ghz – RAM 64 GB – RX 5700XT 8GB & Radeon VII 16GB
I plugged both a Radeon VII and an RX 5700 XT on the motherboard: System info show both use x16 PCIe
Display is 3440×1440 via DisplayPort

Test results


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 See the next post)
  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
