AI buildout supply chain is still bottlenecked by DDR5 DRAM
tengyanAI · x · 2026-07-20
A supply-chain snapshot of the AI buildout says the physical layer is now the bottleneck, even as models commoditize.
- 35 of 54 tracked constraints are described as tight or worse, or 65% overall.
- DDR5 DRAM is the most binding constraint, scoring 86 and labeled critical.
- Advanced packaging / OSAT is also near the top of the bottleneck list.
- The post presents this as a weekly update on where the AI infrastructure chain is under the most pressure.
