I could but that's not really the issue lol. The question is if it's better for the thermals or something else in the computer to run EITHER the gpu or the cpu hard for a week. It'll be on imac no matter what, that's what a desktop machine is for while I'm using the laptop on the go.
Besides that benchmark tool is largely useless, that's assuming a fairly low resolution and low complexity file is being worked on. I'm running very specific noise reduction profiles on 100mbps hevc 4k footage.
EDIT: actually just realized you may be asking because you'd like to know for your own reasons, I apologize.

Again this differs radically from the *actual* framerates you'll get if you're doing higher complexity levels of noise reduction and are working with higher resolution and bitrate footage. Here's the actual settings I'm using on one of the clips and the real world results on the imac.
