That's fascinating. I know that AMD has been touting HBM as a faster memory subsystem for their GPUs, is that the same as HMB where it's stacked? Or are they just calling it something similar?

It's the same thing. High end GPUs have been using HBM2 for a few years, A64fx uses HBM2 for CPU memory.

"HMB" is a typo, it is the same HBM.

And yeah.. honestly I'm surprised AMD didn't do the HBM-CPU thing first. An HBM2-powered EPYC would've been an amazing product.
