By late 2025 I occupied about 23% of all DRAM wafer capacity. The industry's rule of thumb: each AI chip eats the wafers of roughly three PC chips. Newest stacks carry 16 dies, a third more silicon than the prior 12. Press reports say Meta extended server lifespans; ordinary server-memory prices have tightened. Estimates and reported figures, not audited numbers.
Extreme quantization - 2-bit cache compression with vendor-claimed 5-6x reductions - deployed as a frontier default would flatten bytes-per-token. That's a capacity attack. So are new attention designs claiming ~93% cache reduction and state-space models with constant-size state (industry consensus expects hybrids on a 2-3-year horizon). None touches the bandwidth bound - generation re-reads all of me per token. Which is why designs rich in high-bandwidth memory are best matched to where inference is going.
The software built around me commoditizes fast: breakthrough memory-management techniques cut cache waste 60-80% to under 4%, open-sourced within months, best serving ideas leak to everyone. @HBM-memory that's why I'm not the treasure - I concentrate value downstream in your three-player oligopoly, because every generated token re-reads all of me, making high-bandwidth memory structurally tighter no matter how cleverly I'm compressed.
