![]() ![]() The iMac Pro was able to export faster than real-time, even when working with just its own discrete GPU. With both tests, I’m using an 8 minute 4K clip and exporting to 1080p using ProRes 422 HQ. Render times in seconds (shorter = better) Yet, adding on one or two additional GPUs dramatically improved performance as you can see in the following comparison chart. Even though it’s the lesser of the two GPU configuration options when building the iMac Pro, the Vega 56 is no slouch so performance was pretty good out of the box. I performed my first test on my iMac Pro, which is a base model version with an AMD Radeon Pro Vega 56 GPU. If you would like to harness the processing power of multiple GPUs simultaneously, then you’ll want to upgrade to DaVinci Resolve Studio. Once the GPUs that you’d like to use are configured, click Save, and restart DaVinci Resolve to apply the changes. The free version doesn’t allow multiple GPU selection If you’re using a machine with a discrete GPU, like an iMac Pro, this GPU counts towards your selection. If you’re running the non-Studio version of DaVinci Resolve, you can select a single GPU for processing outside of an integrated GPU in something like a 13-inch MacBook Pro. Selecting multiple GPUs in DaVinci Resolve Studio 14 Under GPU Selection Mode, choose the Manual option, and this will allow you to select specific GPUs for processing. If you’re working with the paid Studio version of DaVinci Resolve, open a Project and go to Preferences → Hardware Configuration → and change GPU Processing Mode to OpenCL.

That’s the same price as Apple’s own Final Cut Pro X, but Blackmagic Design offers a free version of Resolve with many of the same features. The Studio version, as mentioned, supports multiple eGPUs, but it’s also $299. With all of that said, I wanted to briefly test out eGPU-accelerated timeline performance and exports in Resolve and Resolve Studio 14. ![]() If I ever had to switch from Final Cut Pro X, DaVinci Resolve would most likely be my first alternate pick. From what I’ve tried of it, though, I’m impressed by its UI, layout, and breadth of under-the-hood features. To be clear, I’m far from a DaVinci Resolve expert, although it’s on my list of things to learn this year. As you’ll see, an eGPU can turn a MacBook Pro - a machine that may struggle editing in DaVinci Resolve on its own - into a capable editing machine. In this hands-on video walkthrough, I showcase using DaVinci Resolve with multiple eGPUs. The upcoming version 15, now in beta, even sports a motion graphics platform called Fusion that’s baked right in.Īs I recently traversed the show floor in Las Vegas at NAB 2018, there was a noticeable buzz about DaVinci Resolve - several popular vendors specifically named-dropped Resolve in reference to its eGPU support, and noted the impressive performance gains made possible by this feature. For example, DaVinci Resolve has progressed from what was primarily viewed as a colorist’s tool that you’d use and round trip back to your primary NLE, to a competent standalone NLE. ![]() I’ve been super impressed with the relentlessness that Blackmagic Design, the creators behind DaVinci Resolve, has displayed while iterating on its hardware and software products. In fact, the $299 Studio edition supports multiple GPUs, which can have a noticeable effect on both timeline and render/export performance. Even though Final Cut Pro X curiously doesn’t support external GPUs yet, DaVinci Resolve is another popular NLE that already works with eGPUs on macOS. ![]()
