AMD pivots from HBM to LPDDR5X for new Versal Gen 2 memory on package chips

• WarOnPrivacy 3mo ago
  Bandwidth LPDDR5X Moderate (~85-89GB/s) HBM Massive (~1 TB/s per stack)

    Where did you get these numbers, or rather think they would apply as they are? The artice speaks of 288GB/s for LPDDR5x as it will be stacked. Still slower than HBM, but not by as much as you make it.

    From page two: (https://www.servethehome.com/amd-pivots-from-hbm-to-lpddr5x-for-new-versal-premium-gen-2-memory-on-package-chips/2/ https://www.servethehome.com/amd-pivots-from-hbm-to-lpddr5x-...) With AMD’s Versal HBM products, the company was able to offer up to 32GB of memory with 819GB/second of memory bandwidth; meanwhile the new Versal Gen 2 Memory on Package chips will offer 32GB of LPDDR5X with just 288GB/second of memory bandwidth. It's an almost 65% drop in bandwidth, which is still significant, but no 90%+ significant.
