Memory Chips Hit a Wall. GPUs Alone Don't Win Anymore.

The AI boom just triggered a memory chip supply crunch that's reshaping the semiconductor stack. HBM and advanced DRAM are now backlogs. Lead times are stretching. And this changes everything because GPUs only work if you can feed them.

What this means on the ground: The large labs can lock in capacity through long-term contracts. Mid-tier players are getting squeezed on both cost and availability. It's no longer just about getting a GPU cluster. It's about the full machine: GPU, memory, packaging, power. If you're deploying models at any scale, you need to start thinking about memory as a first-class citizen in your cost model.
