Are you conflating GDDR5x with PCIe 5.0?

No.

I'm saying we're due for faster memory but seem to be having trouble scaling bus speeds as well (in production) and reliable memory. And the network is changing a lot, too.

It's a neverending cycle I guess.

		One advantage of Apple Silicon is the unified memory architecture. You put memory on the fabric instead of on PCIe.
