I'm doing some shopping trying to get a GPU that will be used for computation (I'm trying to learn GPU programming), gaming and general display, since the computer's motherboard doesn't have integrated graphics.

My question is - When I run GPU computations on the graphics card can it still be used as a display adapter. The computer has no integrated graphics to that card is currently the only way of getting a display output.

  • Computations will run in the CUDA cores (if using an nVidia card), the discreet GPU will have sufficient processing power to also service your OS & UI for non-computational activities. Commented Feb 10, 2023 at 10:29
  • Your computer needs two graphical adapters for that.

Yes.

While there are some configurations, such as enabling TCC mode, that would prevent display output from working, they aren't generally necessary for GPU computing.

  • We use some custom vision code that uses the GPU and there are no problems with it serving our touchscreen monitor as well. Good answer.
