It goes both ways.
HBM on the die is crazy high performance.
With a bus like CXL you could have a card full of memory chips that is shared by multiple CPUs. The z machines have a system like this it is just proprietary for them.
Memory that is less coupled to the CPU won't be as fast as HBM but you can have a lot more of it.
