HBM is the Ugly Baby: What Now?

At the Raise Summit, Pat Gelsinger called HBM a lousy memory in front of SK hynix, and SK hynix agreed it is not the final solution. The clips missed what followed. This piece separates the two memory problems, bandwidth and capacity, maps SRAM, 3D DRAM, LPDDR, and flash onto each, and rules on which competes with HBM and which only relieves it.

Contents

Inside you will find:

  • What Gelsinger actually said at the Raise Summit, and what the clips cut

  • Why SK hynix agreed HBM is not the final solution

  • The three-fold memory problem: demand, capacity per token, bandwidth per token

  • What is wrong with HBM: thermal, shoreline bandwidth, bit efficiency

  • Bandwidth alternatives that contest HBM directly: SRAM (Cerebras, Groq, Fractile) and 3D DRAM (d-Matrix, Qualcomm HBC)

  • Capacity alternatives that relieve HBM: LPDDR5X on SOCAMM2, flash tiers, HBF
