NVIDIA’s competitive unit has expanded from the GPU to the entire AI factory, co-designing computation, models, data, networking, memory, power, and cooling around modern workloads.CUDA’s ubiquitous install base remains the foundational moat, while four compute-driven scaling laws and falling token costs support demand for increasingly specialized infrastructure.Six-month model cycles versus three-year hardware cycles, plus power and supply-chain constraints, remain key execution risks as Huang describes a potentially much larger computing economy.

China combines centralized political goals with decentralized local competition, allowing mayors and private firms to scale EVs, solar, semiconductors, and AI rapidly.The next growth test is shifting from infrastructure and exports toward household consumption, while property may require 3–5 years—or 10 in a bad transition—and export controls may accelerate domestic substitution.

DeepSeek’s V3 and R1 reset the AI cost curve through reinforcement learning, open weights, mixture-of-experts routing, and MLA, not a mythical $5 million frontier model.With roughly 37 billion of 600-plus billion parameters active per token and custom H800 scheduling, efficiency may expand inference demand, while export controls, TSMC, power, and cooling remain decisive constraints.
