But to achieve that bandwidth they will probably need to use some other technology, because 16x large LPDDR5 memory modules sound, well, unrealistic...

Is the M1 GPU sharing LPDDR4 RAM going to be enough?

Although we may have massive bandwidth, this will limit the Mac Pro to only 256 GB of memory. I don't think this will fly with the Mac Pro customer base. And there's no ECC memory as well, as far as I know, so this is a regression from the existing Mac Pro as well.
We can’t assume much. We may be surprised with ECC memory just how we were surprised by the 512bits bus.
Do we know for sure there is no ECC? I mean, from the looks of it, these are fully custom RAM modules, who knows what's in there... LPDDR5 does have support for channel ECC...
Yeah, I suppose Apple could custom order ECC LPDDR5 memory modules. It looks like the M1 Pro and M1 Max memory modules are custom made for Apple as well, as each module seems to have 128-bits data bus.
