The Mac Studio hardware can do 512GB. That might be a hardware limit of the current architecture.

But the family shouldn’t be limited by that. We’re not going to see M6 Max hardware, because the M7 line is being fast-tracked and pulled forward. And I wouldn’t be at all surprised to see M7 capable of 1-2TB or more.

It is, at the very least, a practical limit. There are unlikely to be enough customers willing to pay $50k+ for a hypothetical 1TB RAM version to make it worth manufacturing.

The limit is strictly to cost of memory at this time. If you wanna get by that limit, you have to, well… design it yourself in house.

		Do you really think that Micron, Samsung and SK hynix are working in a cartel to prevent DDR5 memory from being manufactured? Spoiler alert: they're supply-constrained too. Their customers will pay to outbid Apple, just like how Apple outbid the industry on TSMC's 5nm node.

M5 Ultra has 64 channels and the densest LPDDR5X chip is 16GB - so they could produce 1TB Macs but I doubt Micron or Samsung has any to sell.

And given the pricing of the 512GB model over $20,000, I image a 1TB version would be $50,000+.

		The last Intel Mac Pro could rock 1.5 TB.
