Are you talking about the M1 Extreme? This is extremely expensive, and I suspect the dual die GPU only works because of Metal.
TBH I prefer AMD's 7900 series approach of pushing the memory controller + cache out onto little memory controller dies. This allows for a monolithic GPU with a really wide bus, without all that wasted space on the controller/cache/pins. And those dies don't care about being split up since the memory access is interleaved anyway.

- brucethemoose2 3y agothonk I can't remember, you are probably right. There is the little, medium, and big die, and the 2x big die.
- sliken 3y agoThe biggest single die is the m2 max. Dual die chip is the ultra.
- olliej 3y ago"M1 Extreme? This is extremely expensive" hence the name :D That said I think it's pro and ultra, and I can't recall which (if not both) use the magic interconnect
