I want to buy used laptop with rx6600m and r7 5800h
Does switch between discrete gpu and apu work on linux for amd gpus?
Maybe there are some pitfalls?

    This is render offloading, not GPU switching. GPU switching implies switching the primary rendering device (the one power the displays) entirely rather than rendering on a separate GPU and copying the output to the primary.

      Most gaming laptops these days don’t support true GPU switching as it requires a hardware mux to switch the display between the GPUs. Every gaming laptop I’ve used from the past decade has been muxless and only used render offloading.
