What are the minimum compute capability requirements for:
CUDA® is a parallel computing platform and programming model that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).
You can verify that you have a CUDA-capable GPU through the Display Adapters section in the Windows Device Manager. Here you will find the vendor name and model of your graphics card(s). If you have an NVIDIA card that is listed in http://developer.nvidia.com/cuda-gpus, that GPU is CUDA-capable.
All GPUs NVIDIA has produced over the last decade support CUDA, but current CUDA versions require GPUs with compute capability >= 3.0. The Turing-family GeForce GTX 1660 has compute capability 7. x.
You can use CUDA without switching rendering to the Nvidia graphics. All you need to do is ensure that the Nvidia card is powered on before starting a CUDA application, see Hybrid graphics#Fully power down discrete GPU for details.
