There's an extended compute capability 9.0a for Hopper that was introduced in Cuda 12.0: https://docs.nvidia.com/cuda/archive/12.0.0/cuda-compiler-driver-nvcc/index.html#gpu-feature-list
E.g. Cutlass leverages it:

This ./upstream subfolder contains fixes for FindCUDA that are introduced in
later versions of cmake but cause generator expression errors in earlier CMake
versions. Specifically:
-
a problem where a generator expression for include directories was passed to NVCC, where the generator expression itself was prefixed by
-I. As the NNPACK include directory generator expression expands to multiple directories, the second and later ones were not prefixed by-I, causing NVCC to return an error. First fixed in CMake 3.7 (see Kitware/CMake@7ded655f). -
Windows VS2017 fixes that allows one to define the ccbin path differently between earlier versions of Visual Studio and VS2017. First introduced after 3.10.1 master version (see Kitware/CMake@bc88329e).
The downside of using these fixes is that ./upstream/CMakeInitializeConfigs.cmake,
defining some new CMake variables (added in
Kitware/CMake@48f7e2d3),
must be included before ./upstream/FindCUDA.cmake to support older CMake
versions. A wrapper ./FindCUDA.cmake is created to do this automatically, and
to allow submodules to use these fixes because we can't patch their
CMakeList.txt.
If you need to update files under ./upstream folder, we recommend you issue PRs
against the CMake mainline branch,
and then backport it here for earlier CMake compatibility.
