2. If you are using Premiere Pro on a Windows machine, you will benefit hugely from a discrete GPU
3. When using the Arm-optimized Beta version of Premiere Pro, the M1 iMac was surprisingly fast
In all things Apple, you give up control in exchange for stability, speed, and a seamless experience across MacOS and iOS devices. In all things Adobe, you give a little sanity and a monthly offering of cash or credit in exchange for the features, tools, and granular controls that many working pros demand.
If you are much faster editing on an app that renders slightly slower, it doesn’t matter. It might have been interesting to add Resolve in that render mix. I’d also appreciate adding the cost of computers, drives & GPU to these comparisons. My current Win machine (AMD threadripper 24 core, RTX2080ti combo) seems to be limited mostly by drive speed on renders, not the CPU/GPU/software. I doubt I could do as well for the same price with Apple hardware, although I am really interested in their ARM chips.
