Behind Nvidiaâs Redevelopment of its H20 Chip
Following discussions between China and the US, an agreement has been reached to cut tariffs – but the US is still announcing proposals to compete with China’s semiconductor industry.
The latest proposal, the Chip Security Act, mandates that AI chips under export regulations, along with products containing these chips, be equipped with location verification systems to help detect diversion, smuggling or unauthorised use.
Meanwhile, the semiconductor industry finds itself at the epicentre of the escalating US-China technological competition, with the Biden administration’s expanding export controls presenting substantial challenges for global technology firms.
As a result, Nvidia is preparing to launch a modified version of its H20 AI chip for the Chinese market within the next two months, following restrictions on the original model under US export controls, according to Reuters.
The company – which has informed major Chinese customers, including cloud computing providers – plans to release the revised H20 chip in July, Reuters says.
The evolution of Nvidia’s H20 chip modifications
The US government has restricted exports of Nvidia’s most sophisticated chips to China since 2022, citing concerns regarding their potential military applications.
The H20 was introduced following Washington’s tightening of export controls in October 2023, which imposed limitations on computational density and interconnect speeds for AI processors.
Yet the H20, previously Nvidia’s most capable AI chip cleared for sale to Chinese customers, was effectively barred from the market after US officials notified the company last month that the product would require an export licence.
In response, Nvidia has established new technical parameters to guide the development of modified chip designs.
These specifications will result in downgrades from the original H20, including reduced memory capacity, according to a source familiar with the plans.
Another source with direct knowledge of the modifications told Reuters that downstream, customers could potentially modify the module configuration to adjust the chip's performance levels.
Impact on the Chinese AI market
Chinese technology corporations including Tencent, Alibaba and ByteDance increased H20 chip orders earlier this year in response to growing demand for cost-effective AI models from companies such as DeepSeek.
Furthermore, Nvidia had accumulated US$18bn worth of H20 orders since January, showing the significance of the Chinese market to the company's global business strategy.
Therefore, Nvidia’s CEO Jensen Huang addressed the importance of maintaining access to Chinese customers when visiting Beijing last month, shortly after US officials announced the new export licence requirements for the H20 chip.
According to Reuters, Jensen said: “We hope to continue to cooperate with China,” in a meeting with Ren Hongbin, Head of the China Council for the Promotion of International Trade, acknowledging the need to balance compliance with US regulations whilst serving the needs of Chinese customers.
Yet, the modifications to the H20 chip reflect the ongoing tension between commercial interests and national security concerns in the semiconductor industry, as companies navigate complex geopolitical restrictions whilst attempting to maintain access to global markets.
