I assume when LPDDR5x becomes generally available it will go in all of Apple's Macs. It's been their MO to offer the fastest LPDDR RAM generation available. When it comes to which Macs we'll see it in first, it might be the Mac Pro, if initial production of LPDDR5x is too low in volume to put it into Apple's less expensive machines.LPDDR5X is supposed to have up to 64GB chips, meaning a Mn Extreme Mac Pro could have up to 1TB of RAM...?
My initial thought would be that Apple keeps LPDDR5X to the ASi Mac Pro, but scale of economics might mean Apple places LPDDR5X in the Mac Studio as well...?
Back in Nov. 2021 Andrei Frmusanu of Anandtech wrote: "We generally expect LPDDR5X SoCs and products to start being released for the 2023 generation of devices." Not sure how that time has shifted since then. But this suggests, if we do see LPDDR5x in Macs, it will only be for ones released in 2023. Further, it may be the 64 GB LPDDR5x sticks won't be available until later in LPDDR5x's life cycle.
Also, I made a typo in the post of mine you quoted. I meant to write (change enlarged & bolded):
They did put faster RAM in the M1 Pro/Max (LPDDR5) than the M1 (LPDDR4x), so maybe they'll do the same with the M2 Pro/Max (LPDDR5x?) vs. the M2 (LPDDR5).
Finally, I should add I'm not sure if we'll see LPDDR non-ECC RAM in the Mac Pro. They might decide to go with DDR ECC RAM instead.
