Recent GPU versions of tensorflow require compute capability 3.5 or higher (and use cuDNN to access the GPU.
cuDNN also requires a GPU of cc3.0 or higher:
cuDNN is supported on Windows, Linux and MacOS systems with Pascal, Kepler, Maxwell, Tegra K1 or Tegra X1 GPUs.
- Kepler = cc3.x
- Maxwell = cc5.x
- Pascal = cc6.x
- TK1 = cc3.2
- TX1 = cc5.3
Fermi GPUs (cc2.0, cc2.1) are not supported by cuDNN.
Older GPUs (e.g. compute capability 1.x) are also not supported by cuDNN.
Note that there has never been either a version of cuDNN or any version of TF that officially supported NVIDIA GPUs less than cc3.0. The initial version of cuDNN started out by requiring cc3.0 GPUs, and the initial version of TF started out by requiring cc3.0 GPUs.
