We can see that DIMMs are just taking up too much space now and even with 12 channels it’s still not crazy fast bandwidth when you compare it to HBM4.
I can see the hierarchy moving towards:
large L3 cache -> a separate stacked die of L4 cache (Adamantine adaptation) -> 256GB to 1TB of hbm4 system memory all buffering a near unlimited amount of CXL 3.0 memory.
