[2026 In‑Depth Hardware Market Analysis] Part 3. Graphics Card Price Soaring: TSMC’s Dual Bottlenecks and Local AI, KV Cache
1. Wafers are scarce, but back‑end is worse: TSMC’s dual bottleneck When analyzing GPU price rises, it’s a mistake to assume only wafer capacity is tight—both wafer fabs and packaging are severely constrained, with packaging the more critical choke point. TSMC’s leading‑edge wafer lines are fully booked by Apple, Qualcomm, and AI accelerator orders from NVIDIA and AMD. There simply isn’t enough die capacity for consumer GPUs. Even worse is TSMC’s back‑end CoWoS packaging. After October’s big tech announcements, AI firms reserved CoWoS capacity through the end of 2026. Even if a consumer GPU die is produced, the final packaging step is dominated by AI chips that pay far higher margins, creating a dual bottleneck that forces huge premiums to get packaging slots. 2. Local AI inference and KV cache drove GDDR costs skyward Hidden behind HBM headlines is explosive demand for GDDR memory. Local AI inference on personal PCs has surged. To run large language models smoothly, KV cache spac...
