What does "better" mean?

The simple calculations typically used for rendering graphics can easily be parallized on the GPU, hence it's faster. But the result should be identical if the same calculations are done on the CPU.

Also GUI frameworks like iced and egui typically support multiple rendering backands. I know iced is renderer agnostic, and can use a number of backands including the GPU graphics APIs Vulkan, DX12 and Metal.
