Recently, I just bought RTX 3070 Ti for deep learning.
I was going to install the CUDA Toolkit, but when I looked for the CUDA Enabled GPUs list (CUDA GPUs - Compute Capability | NVIDIA Developer),
the GPU is not on the list. The nearest model is RTX 3070.
I am kinda worrying if my GPU doesnt support CUDA.
Yes, it is. Compute capability 8.6 (sm_86). This is a fairly new GPU model and NVIDIA is sometimes slow to update their manually maintained public lists. Generally speaking, all GPUs NVIDIA has been shipping for the past 12 years or so have been CUDA enabled, though some old models may no longer be supported by modern versions of CUDA.
