> Is it some subset of GPU commands that's required for desktop, compared to AAA game?
Yes. Compute shaders and geometry shaders are big features. Vulkan, DX12 and Metal also brought a jump in performance at the API level by allowing developers to batch commands sent to the GPU.
Desktop environments can and do leverage those newer APIs to get marginally better battery life. Asahi will miss out on those benefits, but the performance will be insanely better than “no GPU at all”.
