Memory options range from 16 to 64GB (the latter of which can only be had with the Max) and 512GB all the way up to 8TB. The company sent along the M1 Max with a 10-core PU and 32-core GPU, 64GB of RAM and 2TB of storage. These things add up fast, of course, but welcome to the shopping cart.
Ultimately, I think the company did the right thing here, offering the Max as an upgrade for both systems, at $200.
