AI means it has npu, Max+ is marking the memory channel, PRO is a normal label for chips that have extra security baked in, it has been this way since forever.
To expand, positional definition of adjectives tends to be a bad marketing scheme.
Nobody knows that pro and max mean specific things.
If AMD needs to create a full cross-product of their hardware feature set, because they intend to have a SKU for every possible combination, they probably need a better scheme.
Say what you want about Celeron/Pentium/i3/i5/i7, but it mostly got the idea across (except on the occasions Intel hijacked it to upbrand SKUs).
To be fair - I'd much rather the name be overwrought but clear (once you know or have the decryption key to translate) than to have to look up an even uglier chart that i have ~no chance of memorizing to go 'ok, the Tiberian has X, Y, Z and Q and the Cyrian has Q, Y, but Z is nerfed'
