Re: My Smartphone renders 4K-footage 29x faster than my PC

When I came home from a recent travel I had shot more than 270 GB of 4K-videos - which is roughly about 270 minutes together.
I have a very very basic PC with a Celeron 2 core 2,7 GHz processor and 8GB RAM. While that is mostly good enough for me in every day use, cutting selected clips, put them together and export them as a 4K "movie" is very slow - and a preview is next to impossible.
So I tried whether my ASUS smartphone (Snapdragon 875 / 8 GB RAM) could also handle my Nikon Z50 video clips with it's integrated video editor. To my surprise it could and was extremely fast in rendering with a perfect preview.
I put 10 clips together (1,09 GB) in a row and rendered them to a 1min16sec movie.
Rendering time on my PC with Shotcut - 19min55sec
Rendering time on my Smartphone - 41sec
So the phone was more than 29x faster than my PC. I didn't expect this. I actually wanted to buy a new PC just for video editing. But what components would I really need to just equal the processing power of my smartphone? AMD or Intel (i5/i7/i9), which graphic card and how much RAM woud be needed? I would like to hear what your set up on your Notebook or PC is for a similar rendering time. Thanks a lot!
The key is the GPU - it *has* to support hardware acceleration of whatever codec the camera shoots in and whatever format you want to export to.
It also helps if it has significant amounts of VRAM - Resolve can get a bit finicky if you are doing 4k with less than 6GB of VRAM.
