When I specced out my macbook pro M1 16gb it was entirely possible to get 32 and 64gb without any tie-in to CPU upgrades. You're misremembering. The Macbook Pro M1 (2020) supported a maximum of 16GB, and the base Mx chips have never been offered in a 64GB configuration. |

And they invariably point out where the official Apple specs fall short of real-world options, such as the RAM limit of the 2018 Mac Mini -- officially Apple says it’s 32Gb (and for the longest time even sites like Crucial.com offered only 2×16Gb sets for that model), but MacTracker very quickly pointed out that it can take 64Gb. IIRC this was right after iFixit did their teardown and realized that the CPU did not have a 32Gb memory limitation, and successfully booted that model with 64Gb.
Now, from what I understand the M1 only allowed 16Gb as the max addressable memory - I dimly remember a video where someone tried to resolder with 32Gb of performance-identical chips that had twice the capacity, and it could still only see 16Gb of it - so it appears to be a hard limit either in the memory controller or as a direct feature of the CPU cores themselves.
