Analysis: China's proposed AI export controls reach beyond chips to design IP, computing infrastructure

Core judgment: Shifting export controls from silicon to design blueprints marks the AI rivalry's entry into the architecture-sovereignty era. Technical cascade: Threshold-based controls on AI accelerator microarchitectures and RISC-V extensions immediately pressure the EDA toolchain and Arm/Synopsys licensing ecosystems. If HBM stacking parameters face export thresholds, SK Hynix and Samsung's advanced packaging lines are directly hit. Controlling interconnect protocols and scheduling algorithms for 10K+ GPU clusters extends compute-as-weapon logic from hardware into the software stack. Compliance risk: Multinational chip firms now face dual-track compliance — the same AI die must meet different IP-core, bandwidth, and cluster-scale thresholds by destination market. The bifurcation effect of the US October 2022 executive order is being mirrored on China's side, dismantling the one-product-multiple-markets delivery model. Market dynamics: TSMC and MediaTek in Taiwan, China face the sharpest pincer — upstream constrained by US tool restrictions, downstream by Chinese IP thresholds. NVIDIA and AMD will accelerate architecture-level trimming, not merely compute downgrades. 12-24 month outlook: Global AI silicon fractures into two incompatible IP ecosystems. RISC-V gains structural momentum; x86/Arm licensing hits a fault line. The ultimate winners are architecture translators who can deliver under both rule sets simultaneously.
