How does HBF compare to the discontinued 3D XPoint?

HBF is NAND and integrated in-package like HBM. 3D XPoint or Optane would be extremely valuable today as part of the overall system architecture, but they were power-intensive enough that this particular use probably wouldn't be feasible.
(Though maybe it ends up being better if you're doing lots of random tiny 4k reads. It's hard to tell because the technology is discontinued as you say, whereas NAND has kept progressing.)
