As far as I know there are only three (four?) M1 chips in existence: M1 8GB, M1 16GB, M1 7-core GPU 8GB. There may be an M1 7-core GPU 16GB but I suspect that there is actually only ONE M1 chip (M1 16GB 8-core) and the rest are binned versions.

The CPUs are binned, the RAM is added after binning them. The RAM is created separately from the processor.

Interesting, I was under the impression the RAM was on the same die.

I have a 16GB Air with 7 GPU cores.

So as the sibling said: CPU is binned (but apparently only for the 7/8 GPU cores), RAM is added separately in the package, not on the die.
