    So... Eons ago when I used Intel apu, I can tell most video encoder to use the Intel QSV for video encoding, leaving the dedicated gpu for rendering games (or anything else).

    Thus allowing the pc to be a media server transcoder, obs streaming server, etc while gaming (or while I'm using it for machine learning stuff). With no performance impact.

    I wonder, Does a pc with ryzen APU and a dGPU able to do that too?

    Yes modern gpu should have very minimal performance impact doing video encoding but IME it could go to 10% hit, and when it goes buggy, it can tank the framerate to half.

    You probably can, but you're still losing performance because you're spending the CPU's L3 and RAM bandwidth.
    And you're also losing performance when using a Ryzen APU vs. a CPU with similar number of cores and clocks because the former has a lot less L3.
