Ok, let's try and make this more readable.
SETUP
This is test is to see how different SMBIOS with iGPU either enabled, disabled or in headless mode have an effect on render speeds.
iMacPro1,1 = iGPU disabled, only dGPU (Vega 64)
iMac19,1 = iGPU enabled, headless (using OC 0.5.9, see code below), in combination with dGPU (Vega 64)
METHOD
Download the footage as described in this post by @verendus. Make a new project in DR 16.2.3 (unfortunately I don't have FCPX), create a new timeline (3840x2160, 60 fps), drop the clip in there, and export out, either to QuickTime (MOV) or MP4, and time the export (DR shows how long the export took after it's done).
My machine: i9-9900KS, 64GB RAM, Vega 64 8GB
RESULTS
DISCUSSION
I noticed that GPU utilization (as measured by looking at Activity Monitor) is near 100% on iMacPro1,1; but only ~50% on iMac19,1 during rendering, which makes sense I guess? I'm not sure how I can see QSV utilization other than looking at CPU utilization, which was ~200% for both iMacPro1,1 and iMac19,1.
As this is why I built this setup, I'd love to dig deeper, and I'm willing to do a lot more testing if needed. Hope this contributes in some way!
