Both, same speed, same quality and output file size.

I've done some tests between an RTX 3080, a 13700K, ARC 770, and an RX6600, and tested encoding REMUXs using H265 1080p preset on Handbrake . The Intel is noticeably better quality and almost discernible from the original remuxs I have, also, the file size was better than the 3080 and the 6600. 3080 quality was far better than the AMD which was bodgie as. I have not yet tested a 4000 series card. I did try an ARC A770 in my 12700K build (Unraid), the card is unsupported and I could only use the Intel UHD. My 12700K build (UHD 770) is currently running Unmanic with 8 workers on my library (H265 1080p, ICQ 28, look ahead). It's getting me around 900GB free per week working through various TV shows and movies. This is using UHD graphics. I'd say the best value for money today lies in the i5 13500, with the best core count per dollar, as well as including the UHD 770 Graphics. Note the difference if you go down to the 10 core 13400, the UHD 730 has 1 "Multi-Format Codec Engines" whereas the slightly more expensive 14 core 13500 has 2. When testing with Handbrake, I didn't feel like there was any encoding performance difference between the Intel UHD Graphics and the ARC. The performance seems to be governed by the amount of "Multi-Format Codec Engines" available on an Intel product.
