Cerebras processor has 1.2 trillion transistors and uses 20 kW of energy. Apples new M1 has 16 billion transistors (so is a factor of 75 smaller) and uses only 20 W (so a factor of 1000 smaller). So Apples M1 is 1000/75 = 13.3 times more energy efficient than Cerebras processor. So if your aim is processing power per Watt you should better build a supercomputer from a cluster of Apple M1 CPUs.
