Chatreey has introduced the AMR5 and AM08, a pair of mini-PCs based on AMD Ryzen 5000 APUs. Available as barebones units or with pre-installed memory, the pair feature identical chassis and have similar I/O. Both machines have physical dials for changing performance levels on the fly, too.https://www.notebookcheck.net/Chatreey-AMR5-and-AM08-arrive-as-affordable-mini-PCs-with-unusual-physical-performance-dials.695202.0.html
It's nothing new. In the old days, PC cases have a turbo button that you can push to switch from performance mode to eco mode.
