It's also absolutely wild that you apparently cannot spec one with more than 32GB, for any amount of money? Wow.

Not that I blame Apple here, for once. Seems like they're trying to cope with the limited quantity of RAM they can procure. And with the paltry bandwidth (170GB/s) of these CPUs they're a bad choice for anything but tiny local models anyway.

That's for the base model M6. The Pro can take more, the Max even more, the Ultra the most.

They're not making those models for the M6 though; they rerouted their resources to making M7 faster at running local LLMs.

If you want more bandwidth, get an M5 Pro, Max, or Ultra. If you want a lower power base model, get the M6. If you want to have your cake and eat it too, wait for the M7, reportedly in the spring.
