Apple offers a maximum of 64GB of memory on the current 14-inch and 16-inch MacBook Pros, while the Mac Studio can be configured with up to 128GB of memory with the M1 Ultra.
If the M2 Max chip results are accurate, the performance increase will be relatively minor for the upcoming chip.
The first Macs expected to feature the M2 Pro and M2 Max chips are rumored to be updated 14-inch and 16-inch MacBook Pros, with the Mac Studio to follow sometime next year.
Apple has several Macs in the work for 2023, including updated MacBook Pros, an updated iMac, and the long-rumored Apple silicon Mac Pro.
