Micron chart reveals compute-HBM bandwidth gap, new solutions emerge

By PulseAugur Editorial · [1 sources] ·

A chart from Micron, presented at Hot Chips 2026, illustrates a significant disparity between the growth of compute power and High Bandwidth Memory (HBM) bandwidth. While compute capabilities have tripled every two years, HBM bandwidth has seen less than a twofold increase over the same period. To address this bottleneck, innovations like placing memory closer to compute and integrating processing units within memory itself are being developed, with Samsung already shipping a product that demonstrated a threefold increase in token processing speed for Llama 3.1 8B.
