Chinese AI companies are optimising software to handle growing inference demand while access to high-end Nvidia processors remains limited. Domestic chips can support some inference workloads, but complex coding tasks still depend partly on scarce Nvidia capacity.
China has approved five automotive-chip certification and accreditation standards built around a “1+4” framework, effective October 1, 2026. The standards aim to unify evaluations for chip design, certification, testing, and automotive computing, reducing duplicated validation and improving trust in domestic suppliers.

China is increasingly deploying supernodes—clusters of dozens or hundreds of chips and supporting hardware—to scale AI computing. By combining larger quantities of domestic chips, these systems aim to deliver competitive performance despite US export restrictions on advanced AI chips.

Marvell Technology has granted Google the right to purchase up to $12.2 billion of Marvell shares as part of a custom-chip arrangement. Google will buy Marvell’s custom chips, and Marvell’s stock rose as much as 14% after the disclosure.
