I was fortunate to get my hands on an AMD Radeon RX 580 for a night, which I ran several benchmarks on, to compare how well it would do against my current Nvidia GTX Titan X (Maxwell). I didn't have much time, but I did some quick tests pertinent to some of my main workflows, primarily 4K video editing, grading and transcoding using Adobe Premiere Pro. All on my 5,1 cMP with latest 10.13.3.
Here are attached benchmarks comparing the latest versions of Geekbench and LuxMark. Furthermore, I ran an optimize test using NeatVideo to see how well the GPUs faired in my system.
Of note, even though the synthetic tests scored similar between the cards in GB, my render and transcode tests showed a fairly wide performance difference between using CUDA on the Titan and OpenCL on the RX580 (although I recognize the cards are not direct competitors). Hopefully this helps someone somewhat looking between Nvidia and AMD cards currently for video work. It gave me a general idea of where some of these AMD cards land at least.
Test clip in Premiere Pro: 4K DCI ProRes (HQ), 30 sec TRT with the following applied:
• Rec 709 LUT applied
• Lumetri Color filter applied
• Gaussian Blur with optical tracking applied to whole clip
• Secondary Colorista grade applied
• basic crop filter applied
I did a timeline render test first. Then wiped out the renders and did a 4K to 2K H.264 transcode, which utilizes the GPU 100%.
