US–China Tech Rivalry Spreads Into Embodied AI and Electric Mobility

A Chinese robotics start-up has beaten Nvidia on a global embodied intelligence benchmark, underscoring how quickly the US–China technology rivalry is metastasising beyond semiconductors and cloud software. Spirit AI, based in Hangzhou, scored highest on the RoboArena leaderboard with its Spirit v1.6 foundation model, edging out Nvidia’s Cosmos3-Nano-Policy. The result is the latest signal that China aims to lead in the algorithms powering next-generation robots, even as Washington-based firms dominate the underlying hardware. Days later, Nvidia confirmed it had begun shipping next-generation co-packaged optics switches manufactured with TSMC, which can handle 400 terabits per second and target the crippling energy costs of AI data centres. The contrast is instructive: one side advances the ‘brains’, the other the ‘nervous system’ of the intelligent economy.

In related moves, BYD formally confirmed it is developing humanoid robots, arguing that automotive artificial intelligence and robotics share a common technological foundation and could be sold through its existing dealer network. Separately, Chinese researchers published a study demonstrating how a wearable robot helped children with spinal muscular atrophy to stand for the first time after six weeks of resistance training. Viewed from laboratories in Beijing, these efforts form part of a broader drive to apply AI to physical systems, blurring the boundaries between mobility, health care and industrial automation.

Meanwhile, the competition in electric vehicles is rewriting consumer markets. BYD revealed the interior of its Dolphin G, tailored for European buyers and set to be assembled in Hungary, with a minimalist cabin and digital-first controls. In Latin America, the company raised prices on most models in Argentina by up to six per cent, even as a popular influencer publicised her purchase of a Dolphin Mini. In Brazil, a test of the GAC Aion UT found the budget electric hatch sacrifices equipment for power and space, pricing it between BYD’s own Dolphin Mini and larger Dolphin. Nvidia’s financial footprint is also visible: it has become a core holding in Mexican mutual funds, with the value of positions rising from 3.9 billion pesos in early 2024 to 9.4 billion pesos this April.

Underpinning these shifts, the personal computer is being reinvented from opposite ends. Qualcomm’s new Snapdragon C targets US$300 machines to compete with Apple’s MacBook Neo, while Nvidia’s forthcoming RTX Spark system-on-chip is built for agentic AI workloads and aims at the high-performance tier. The strategies reflect diverging bets on where computing value will accrue, yet both require the advanced packaging and optics that TSMC and its partners provide.

Analysts in London see a landscape where no single technology or region can claim decisive advantage. The combination of Chinese gains in embodied intelligence, American infrastructure plays and Asian manufacturing muscle creates a multipolar scramble. As talent, capital and policy converge on this expanded frontier, the only certainty is that the old distinction between digital and physical competition has collapsed.
