alt Hacker NewsYou got me curious so I looked up the previous chips[0].
Memory bandwidth M1: 68 GB/s M2: 100 GB/s (47% increase) M3: 100 GB/s (0% increase) M4: 120 GB/s (20% increase) M5: 153 GB/s (27.5% increase)
So, M6: 170 GB/s (11% increase) doesn’t seem impossible, though I would have expected more.

The different models of chips and memory config have very different memory speeds as well.
Eg the M4 Max 128GB has a bandwidth speed of 500GB/s+. And that's true for other models as well.
But as you note, the base speed has also increased over the versions.
