By end of 2028, high-bandwidth memory (HBM) and advanced packaging remain the hardest parts to secure in the AI chip supply chain. Nvidia, AMD, and other AI accelerator makers have to slow their datacenter shipments because TSMC, SK Hynix, and Samsung can't produce enough HBM or complete the intricate multi-die stacking fast enough to keep pace with wafer availability. Customers experience delivery delays measured in quarters, not months, and the bottleneck visibly tightens rather than loosens through 2027-2028.

By end of 2028, HBM and packaging constraints have eased enough that they no longer set the pace for the entire supply chain. Either manufacturers found new capacity, yields improved sharply, or demand growth slowed—but the choke point moved elsewhere: power delivery, interconnect materials, or something in the logic layer itself. Shipments of completed AI chips accelerators scale with foundry capacity, not with memory or packaging constraints.
