Premiere Pro running Slower with eGPU - Help Needed
I recently picked up a Razer Core X Chroma and a Sapphire Radeon VII 16GB card to plug and play with my 15-inch Late 2016 MBP - 2.9 GHZ Quad-Core i7. I initially tested it out on some games and was getting up to 100% utilization. Then I tried it in Premiere Pro and was getting worse performance than my internal AMD Radeon Pro 460. Nevermore than 9% utilization.
I'm running Catalina 10.15.1 and have the latest version of Premiere Pro 14.0.
I've checked the "prefer eGPU" box, I've played with both Metal and Open CL in Premiere and my external monitor is being powered via display port so my lid is closed. I've got a 40GBPS TB3.1 cord connecting my computer to the eGPU. I've swapped sides with the cord so it was accessing different thunderbolt Bus connectors and yet I've had no luck.
So with all that being said, does PP 14.0 not offer any benefit? Or am I missing something?
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
I used to run a Vega 64 eGPU and it would result in improved performance (admittedly never huge). With the Radeon VII, export times are considerably longer, it never utilizes more than 2 percent, and playback speeds in the app are terrible.
After further testing, it appears this is isolated to Premiere Pro 2020. 2019 (13.1.5) handles the Radeon VII as expected.
Playback is normal, and export times are significantly reduced on my simple test scene (00:59 vs 3:51). I achieved 40 percent utilization (it could have been more, I imagine it's because the test scene is relatively simple 1080p ProRes with some stacked lumetri nodes).
I've filed a bug report and suggest you do as well 🙂 https://www.adobe.com/products/wishform.html
