Interesting. But there is also this from WCCFTECH:
MacBook Pro With M1 Max Is Barely Faster Than Microsoft’s Surface Laptop Studio in 8K Video Render Test
That's about the 8K video rendering test which was performed on Adobe Premiere Pro (it's available as AS native).
Does Premiere use the GPU to render, though, or is rendering just GPU accelerated? Not a rhetorical question, I've never used it. But from what I've read, Premiere isn't a GPU renderer.
