https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      View GPU utilization, both for the total activity percent and individual

+      Works with both the open drivers and AMD Catalyst. Total GPU utilization
+      is also valid for OpenCL loads; the other blocks are only useful for GL
+      loads. Requires root rights or other permissions to read /dev/mem.
