Nvidia readies new Blackwell-based accelerators tailored for China under US export limits

Nvidia is reportedly developing new China-only accelerators based on its Blackwell architecture, with performance aimed above today's H20 while staying under U.S. export thresholds, according to people familiar with the plans cited by Reuters. The effort underscores how access to artificial intelligence hardware remains a central fault line in U.S.–China tech relations.

Reports point to multiple models. A single-die design, tentatively called B30A, aims for about half the raw compute of the dual-die B300 while keeping its high-bandwidth memory and the NVLink interconnect. Nvidia aims to get test samples to Chinese customers as early as September, pending regulatory clearance. Another Blackwell card, the RTX 6000D, targets inference and professional graphics.

Technical constraints appear calibrated to U.S. export restrictions. Reuters says RTX 6000D employs conventional GDDR memory and delivers 1,398 GB/s of memory bandwidth, just below the 1.4 TB threshold set in April, while the B30A's single-die configuration would naturally cap throughput and capacity versus B300. Initial RTX 6000D shipments to select Chinese clients are slated for September.

President Donald Trump recently floated allowing scaled-down next-generation parts for China and taking 15 percent of China-origin chip revenue from Nvidia and AMD for the United States government. Lawmakers in both parties warn that even curtailed accelerators could chip away at the United States' edge in artificial intelligence.

Nvidia argues it must keep Chinese developers in its ecosystem or risk a full switch to domestic alternatives. Huawei has advanced rapidly, with some models approaching Nvidia's compute figures, though analysts still see gaps in software tooling and memory bandwidth. At the same time, Chinese state media have raised security allegations about Nvidia hardware, and authorities have cautioned firms against buying the H20, complicating the company's channel strategy.

Nvidia, for its part, says it continuously evaluates products "to be prepared to compete to the extent that governments allow," and that all offerings ship with full approval for "beneficial commercial use." The company received permission in July to resume H20 sales after an abrupt April halt, and China accounted for 13 percent of Nvidia's revenue in the last fiscal year, highlighting the market's importance.
