Ok. However the posts in this thread were asking how the M1 Macs could use less RAM than Intel Macs, not if they were more optimized. The GP started with:

>This quote doesn’t really cover why M1 macs are more efficient with less ram than intel macs? You’ve got a memory budget, it’s likely broadly the same on both platforms

Well, if less memory is used to store garbage thanks to RC, less memory is needed. But that was largely discussed in other sub-comments hence why we focused more on the optimisation aspect in this thread.

But both Intel Macs and ARM Macs use RC. Both chips are running the same software.
