Hot Chips 2026: Samsung makes LPDDR5X smart with logic unit in memory — LPDDR5X-PIM is 3.01x faster than LPDDR5X in AI inference with 8x the bandwidth

What happened

Samsung introduced the industry's first LPDDR5X-PIM memory, achieving 3.01x faster AI inference speeds compared to standard LPDDR5X. This technology addresses the high cost of HBM by offering a cheaper in-memory processing alternative for AI workloads. Watch: Potential demand shift from HBM to LPDDR5X.
