Qualcomm unveils HBC near-memory AI architecture

Qualcomm introduced HBC near-memory compute architecture, disaggregating the AI accelerator from the SoC and placing it under the LPDDR DRAM stack. The company claims 6x higher bandwidth-per-watt compared to HBM and over 200x capacity compared to on-chip SRAM, using through-silicon vias without expensive HBM or advanced packaging.
