Memory is two-thirds of what an AI chip costs to build
Thousand Miles AI
Epoch AI published a component-cost breakdown of a frontier AI accelerator this week, and the headline number is one that reframes a lot of the 2026 GPU conversation: memory now accounts for roughly two-thirds of the bill of materials. The logic die — the thing most people picture when they hear "AI chip" — is no longer the dominant cost. The stacks of high-bandwidth memory glued to it are. That is a quiet inversion. A decade ago, on a server GPU built for general HPC, the logic die was the head
