What is asitop

A Python-based nvtop-inspired command line tool for Apple Silicon (aka M1) Macs.

asitop uses the built-in powermetrics utility on macOS, which allows access to a variety of hardware performance counters. Note that it requires sudo to run due to powermetrics needing root access to run. asitop is lightweight and has minimal performance impact.
