Video encoding doesn’t use CUDA but rather NVENC.
However AMD is still as terrible at H264 as ever, and their AV1 encoder also has a hardware defect they’ve patched by forcing it to round up to 16 line multiples, so it is incapable of encoding a 1080p video and instead outputs 1082p that won’t be ingested properly when streaming.

Also the AV1 quality is not as good as intel+nvidia even with resolutions that aren’t glitched. AMD seemingly went big on HEVC (supposedly because of stadia?) but everything else is a mess.
And most places won’t touch HEVC because of the licensing costs. Microsoft makes it a windows store plugin you have to buy separately etc. somewhat odd that google picked HEVC for stadia but I guess those customers are actually directly paying you vs YouTube being a minus on their balance sheet (at least until recently possibly)
