High Bandwidth Memory Capacity Reallocation Accelerates
Manufacturers are redirecting wafer capacity away from commodity DRAM and NAND toward high bandwidth memory production at a pace that has surprised even industry analysts who tracked the AI infrastructure buildout closely throughout 2024 and 2025. This reallocation reflects the substantially higher margins high bandwidth memory commands compared to commodity products, alongside sustained demand visibility from Nvidia and other accelerator makers signing multi-year supply agreements. High bandwidth memory capacity has expanded at roughly 24.0% annually, the fastest growth of any memory category tracked, as manufacturers race to capture AI-driven demand before competitors establish comparable production scale.
Market Impact: Fab utilization reached 89% of capacity
