I thought so too when they launched the M1, but I soon got corrected.

The memory bus is the same as for modules, it's just very short. The higher end SoCs have more memory bandwidth because the bus is wider (i.e. more modules in parallel).

You could blame DDR5 (who thought having a speed negotiation that can go over a minute at boot is a good idea?), but I blame the obsession with thin and the ability to overcharge your customers.

I still have one :) It's an ISA Trident TVGA 8900 that I personally upgraded from 512k VRAM to one full megabyte!!!
