Question AMD 7000 Series Encoder vs NVIDIA 4000 Series Encoder ?

[wellallnasib]

Hello there, I am a small content creator who records gameplay with software like OBS Studio / Mirillis Action! around 120Mbps HEVC and I export edited content at around 60Mbps HEVC with DaVinci Resolve.

I currently have an Nvidia 3070 GPU, but if I switch to AMD GPU will there be a noticeable visual difference ?
Note that I am willing to buy a 7900 XTX. The pricing of NVIDIA GPU in my country is absurd and the importers all work together to keep prices high. For example the 4080 Super is around $1600 and 4070 Ti Super is around $1200. However, AMD cards sell for around their MSRP.

So the question is :
Will there be a noticeable difference in 100MBPS recording in HEVC/AV1 between a 4080 Super and a
7800 XT using OBS and exporting with DaVinci Resolve ?

will there be a noticeable visual difference ?

there shouldn't be any visual difference whatsoever unless you alter your software settings for higher/lower quality output.

the only difference with a more powerful GPU would be the speed at which the video is encoded.

Thank You. Guessed it was the case, but just wanted to be sure before I commit to a new build.
