Does the M1 make programs use less RAM somehow?

I don’t know how, but similar workloads between my intel MacBook Pro and M1 MacBook Air show about half the ram usage on the M1

The M1 seems to be designed around the retain/release cycles that are at the core of everything Apple has been building on going all the way back to NeXTSTEP

This tweet has nothing to do with RAM usage. Maybe about the performance of (uncontended) atomic operations if I'm reading this corectly.

possibly yes due to how it now sits closer to the cpu and other components. Utilization is also different.

the current concern is how all these impact SSD(harddisk) life and health due to how swap memory is managed. It may be the reason why Apple priced such a breakthrough technology so competitively.
