【Midday Deep Dive | AI Cost Breakdown: Storage is "Eating" GPU】
Breaking down the BOM of Blackwell GPU: HBM cost share has surpassed 40%, compared to under 25% in the H100 era, and the next-gen Rubin is expected to break 50%.
The trend is solid: the larger the model, the higher the storage share. GPU companies milk design premiums, while storage firms cash in on hardware materials — only 3 companies globally can produce HBM, raising the barriers.
However, the market gives GPUs a PE ratio of 35-45, while storage is only at 5-10. As cost share rises, valuation multiples shrink; this spread will eventually correct itself.
Tomorrow's NVDA earnings report is crucial, especially for data center revenue and HBM procurement guidance. Historical pattern shows: after NVDA beats, storage stocks tend to rebound more.
