What is a good GPU "top" program for VideoCore Aarch64

I have been looking for an equivalent GPU “top” program that will work on the Raspberry PI 4 that I have. I have looked at https://www.cyberciti.biz/open-source/command-line-hacks/linux-gpu-monitoring-and-diagnostic-commands/ but these are for x86_64 - sudo intel_gpu_top only works on i915 etc.
