Intel doesn't have this problem with their discrete GPUs. People actually use those for machine learning.

  Mostly because apparently they are doing something good with Data Parallel C++, and related tooling.

And games could make use of GPGPU, most notably realistic physics simulations, if AMD weren't dragging their heels

  Games do use GPGPU through DirectX12 compute shaders. Maybe Vulkan compute shaders if cross-platform capability is desired. Video Games already have a huge pipeline of GPU-compute setup for vertex / pixel shaders, geometry shaders and more. Throwing a DirectX Compute Shader / Vulkan Shader on top is no biggie. But this is a lot of cruft to add to a non-video game (gotta initialize DirectX or Vulkan graphics just to start running compute shaders, and ignoring the default vertex/pixel shaders that the APIs are designed for...) > most notably realistic physics simulations Physics simulation is a dead-end. There's no reason to do physics on GPU, because copying the data from CPU->GPU is slow, and GPU -> CPU is slower. By the time all the copying, calculating, and copying back is done, the GPU-physics data is obsolete and the CPU might as well have run it locally in L3 cache instead. I think there's a chance that GPGPU video games could exist, but the graphics would have to be delayed relative to the physics simulation. Time X starts running a step of the physics simulation. Time X+1 the physics simulation copies back to CPU, and gives CPU-time to finalize the results. Time X+2 CPU copies the data into the Vertex/Pixel shaders for rendering to the user. But the game engine, game, and graphics will have to be specifically tailored for GPGPU graphics. Still, real engines like Claybook have done this: https://ubm-twvideo01.s3.amazonaws.com/o1/vault/gdc2018/presentations/Aaltonen_Sebastian_GPU_Based_Clay.pdf https://ubm-twvideo01.s3.amazonaws.com/o1/vault/gdc2018/pres...

Gaming will likely also use locally hosted AI sooner rather than later.
