So there's an M2 Ultra, M2 Max, and M2 Pro. I hate this naming scheme. It is totally unclear how you're supposed to order those in terms of performance.
Even with the Intel i-series, you're not looking at the model name to make a purchase decision. You're looking at the technical specs.
Non-sequential naming also gives them the flexibility to shift new products into the category over time. They do this with the M1/M2 in the iPad.
I think it is hard to justify a ranking that puts anything above “max” unless you are designing for Spinal Tap.
