pro and max had way more cores and gpus and supported way more ram. today's release is the basic version of the new cpu; if you want more ram you can get the m4pro or m4max based MacBook Pros, or wait for the M5pro/max to come out.
so, macbook pro m5 normal, macbook pro m5 pro, macbook pro m5 max. I see M4 still in the offer, which costs more. No wifi 7 on m5 (normal or not). 32GB these days, unified or not, in a pro machine.. I haven't paid much attention to macs over the past few years but I wonder what would Steve Jobs say about this shit.
