Qualcomm has completed hardware validation of its first-generation High Bandwidth Compute (HBC) technology, which stacks LPDDR memory for near-memory computing. The AI250 accelerator featuring HBC is scheduled to sample in early 2027, aiming to replace traditional HBM with a low-power solution delivering up to 133 TB/s effective memory bandwidth.

    Qualcomm Validates HBC Tech; AI250 Chip to Sample in 2027

    • HBC uses vertically stacked multi-layer LPDDR with TSV interconnects, reducing data transfer distance to microns.
    • The AI250 accelerator is expected to deliver 133 TB/s effective memory bandwidth, an 18x improvement over predecessors.
    • Early samples achieved >5x per-watt bandwidth compared to HBM4, with formal products targeting 6x traditional HBM efficiency.
