How important are media codecs engines for the free version?

I'm looking to get a new laptop, I'm a teacher and need to make quick VO videos for my students.

I currently run and old 4800H 2060 gaming laptop which has multiple issues, and was looking to buy something to make rendering faster.

Between intel 255H and AmD 365 cpus I noticed that intel H has 2x media encoding engines unlike lunar lake, and amd, but looking at the free resolve, i cant tell if this would actually help my setup, or just rely purely on the nvidia dGpu. I mostly need to render FHD 30/60 FPS with recorded audio

is that important at all? or is it enough to just get anything with a 5050 and let it use nvidia engines?
