While Cortex-Ms are surprisingly powerful compared to the microcontrollers of yesteryear, they're still targeting the same segment. They are not comparable (in terms of cost, power consumption, performance...) to the ARM in your smartphone, let alone the ARM in AWS Graviton. They have kilobytes, not gigabytes of RAM. They run at double digit megahertz clocks.
