There are no CPU Gflops/W benchmarks online for M1, but my friends who have M1 laptops used this code to test it: https://github.com/brianolson/flops

The M1 is only good at highly specialized tasks that they have custom designed hard/firm/soft-ware for; which are all locked both legally and technically into a tomb where they will remain until the end of humanity.

If you spend one second even thinking about them; you are wasting time for eternity! Infinite waste!

RISC-V with an open GPU and linux is the only saving grace. I doubt we will manage before it's too late at a price/performance that can compete with Raspberry Pi 2/4 for server duty and Jetson Nano for client duty.

Fingers crossed and may you spend your money wisely!
