In China, repair demand for banned Nvidia AI chipsets booms
Some Nvidia AI GPUs in China have been heavily used, leading to higher failure rates
US lawmakers have introduced bills designed to limit smuggling of Nvidia chips
By Che Pan and Casey Hall
BEIJING/SHANGHAI, - Demand in China has begun surging for a business that, in theory, shouldn't exist: the repair of advanced Nvidia artificial intelligence chipsets that the U.S. has banned the export of to its trade and tech rival.
Around a dozen boutique companies now offer repair services, according to two such firms in the tech hub of Shenzhen which say they predominantly fix Nvidia's H100 graphics processing units that have somehow made their way to the country, as well as A100 GPUs and a range of other chips.
Even before it was launched, the H100 was banned from sale in China in September 2022 by U.S. authorities keen to rein in Chinese technological development, particularly advances that its military could use. Its predecessor, the A100, was also banned at the same time after being on the market for over two years.
"There is really significant repair demand," said a co-owner of a firm that has been fixing Nvidia's gaming GPUs for 15 years and began working on AI chips in late 2024.
Business has been so good that the owners created a new company to handle those orders, which now repairs up to 500 Nvidia AI chips per month. Its facilities, as shown in social media advertising, include a room which can accommodate 256 servers, simulating customers' data centre environments to conduct testing and validate repairs.
The rapid growth of the repair industry from late last year supports the view that there has been a significant amount of smuggling of Nvidia chipsets into China. Tenders have shown that the government and the military have made purchases of the U.S. firm's banned AI chips.
Concern about large-scale smuggling of high-end Nvidia products into China has prompted both Republican and Democratic lawmakers to introduce bills that would require the tracking of chipsets so that their location can be verified after they are sold. U.S. President Donald Trump's administration also backed the idea this week.
The thriving repair industry also highlights how Nvidia's advanced GPUs remain in high demand despite new, albeit less powerful, products from Chinese tech giant Huawei .
Though the buying, selling and repair of Nvidia GPUs is not illegal in China, sources for this article were reluctant to draw scrutiny from U.S. or Chinese authorities and declined to be identified.
Nvidia cannot legally provide repair or replacement items for restricted products in China. In contrast, sources said if an Nvidia GPU in another nation has a defect and is under warranty, which is normally three years, the company usually replaces it.
An Nvidia spokesperson said only the company and authorised partners "are able to provide the service and support that customers need. Using restricted products without approved hardware, software, and technical support is a nonstarter, both technically and economically."
REPAIR DEMAND MAY NOT FADE
Nvidia has only just been allowed to recommence sales of its H20 AI chipset, which has been specifically developed for China to comply with U.S. restrictions. Switching over to H20 chipsets is, however, not necessarily a simple or good option for Chinese entities.
Price is an issue as one H20 server with eight GPUs inside will likely cost more than 1 million yuan , industry sources say. H20 chipsets, which have increased memory bandwidth, have been specifically designed for AI inference work, but firms involved in the training of large language models would likely prefer H100 chipsets which are better suited to that task.
Industry sources said some of the H100 and A100 GPUs in China have been crunching data around the clock for years now, leading to an increase in failure rates. Depending on how frequently a GPU is used and how often it is maintained, an Nvidia GPU generally lasts two to five years before needing to be repaired, they said.
According to the first source, his company charges between 10,000 yuan and 20,000 yuan to fix a GPU depending on the complexity of the problem.
The second Shenzhen-based repair service provider - which shifted from GPU rentals to repairs this year - says it can repair up to 200 Nvidia AI chips each month, charging about 10% of the GPUs' original selling price per repair.
Services generally include software testing, fan repair, printed circuit board and GPU memory fault diagnostics and repair, as well as the replacement of broken parts.
In the meantime, smuggling of high-end Nvidia chips continues. Traders of chips in China say customer demand is pivoting to top-of-the-line B200 chips which Nvidia began shipping to other countries in larger quantities this year.
A server with eight B200 GPUs costs more than 3 million yuan in China, they said.

Downtown to Nashville airport in just 8 minutes? Elon Musk's Boring Company unveils tunnel plans
Elon Musk's The Boring Company has announced plans to build a 10-mile underground loop in Nashville in coordination with Tennessee Republican Governor Bill Lee. It's called the Music City Loop. The governor's office said that the Nashville project would come 'at zero cost to taxpayers' and would be 'entirely privately funded". Tired of too many ads? Remove Ads When will Nashville tunnels construction begin? Tired of too many ads? Remove Ads Tennessee' underground tunnel receives criticism Tired of too many ads? Remove Ads Tech billionaire Elon Musk 's ' The Boring Company ' is gearing up to bring its underground tunnel network to Nashville, according to US media reports. The underground freight tunnel will use Tesla vehicles to transport people from the city's downtown to Nashville International Airport in around eight minutes, according to a report in land beneath state-owned roads, Musk's Boring Company initially would dig a 10-mile tunnel from the Music City Center to the airport on the city's southeast side using. All-electric vehicles would be used to carry riders on an eight-minute transit. Tennessee leaders have extended support to Elon Musk's plan to an underground tunnel dubbed the 'Music City Loop' from downtown Nashville to burgeoning Nashville International announcement comes after The Boring Company implemented its first underground Tesla tunnel in Las Vegas in 2021, delivering people to the Las Vegas Convention Center (LVCC). More recently, the emission-free tunnels have been extended to connect nearby resorts with the construction on the Nashville tunnels will start 'immediately,' The Boring Company said. But the company's president Steve Davis said it won't be easy. "Tough place to tunnel. If we were optimising for easiest places to tunnel, it would not be here," he said."You have extremely hard rock, like, way harder than it should be, but it's an engineering problem that's fairly straightforward to solve.'The construction of the tunnel is expected to be completed in two years' time, although previous projects have experienced significant delays. Tennessee Governor Bill Lee announced The Boring Company's intent to build the Music City Loop , a transformative private transportation project that will bring the company's innovative underground Loop system to Nashville at zero cost to taxpayers, marking a bold step forward in advancing mobility, economic growth, and infrastructure modernization across the region," an official statement Music City Loop will remove thousands of vehicles from surface roads each day, easing traffic congestion while creating numerous job opportunities for Tennesseans, the press release said. The Loop system will also extend the lifespan of Tennessee's roads, reduce emissions, and offer a safe, fast, and reliable travel option—particularly during major events and Nashville's peak convention and seasonal the plan to construct underground tunnel has received backlash from other politicians, with Nashville Democratic representative Justin Jones claiming he was 'denied entry' from the announcement, despite Republicans being allowed to attend."This project, which requires state approval, is yet another attempt by Bill Lee and his corporate donors to enrich themselves while neglecting public services and real infrastructure needs, of working class people who commute downtown for work at bars, hotels and restaurants," he said in a statement on Instagram."Musk's Boring Company has been known to violate workplace safety laws and damage water quality, which is why other cities have refused or rejected his Tesla Tunnels, and why they are afraid of being questioned. "Democratic lawmakers in Nashville are demanding answers on the plans, while the state's Republican leaders have jumped at the chance to partner with Musk. A state commission is holding an emergency meeting and public hearing Thursday morning to discuss a 'no cost/mutual benefit' lease arrangement that's been proposed to help the company get the tunnels started, reported Boring Company was founded by Musk in 2017 with a vision to tackle urban traffic by shifting transportation beneath city streets. The idea centers on building efficient, cost-effective tunnels that support high-speed travel, reducing pressure on surface 2022, it secured $675 million in Series C funding, bringing its estimated valuation to approximately $5.7 billion and signaling strong investor confidence in its long-term potential.

Alphabet, Nvidia in talks to back AI firm Vast Data at $30 bn valuation
Alphabet's growth-stage venture division CapitalG and Nvidia are currently in discussions to invest in US artificial intelligence infrastructure firm Vast Data as part of a new funding round that may value the startup at as much as $30 billion, according to a report by Reuters. Vast Data is seeking to raise several billion dollars from major technology companies, private equity firms, and venture capital investors, potentially positioning it among the most valuable AI startups, as investors increasingly focus on the companies powering the AI revolution. CapitalG and Nvidia, an existing investor, are expected to participate in the upcoming round, which could conclude within the coming weeks. Based in New York, Vast Data specialises in storage solutions tailored for large-scale AI data centres, facilitating efficient data flow across graphics processing units (GPUs) produced by firms such as Nvidia. The company's client base includes notable names like Elon Musk's xAI and AI cloud-computing startup CoreWeave. According to bankers and analysts, Vast Data's strategic position within the AI supply chain enhances its appeal as a potential acquisition. TechCrunch previously reported on Vast Data's plans to raise capital. However, the possible $30 billion valuation and the involvement of CapitalG and Nvidia have not been disclosed until now. Vast Data expected to reach $600 million in revenue Vast Data's CEO, Renen Halak, has stated that the company is free cash flow positive. As of January 2025, it had achieved $200 million in annual recurring revenue (ARR), with a strong pipeline of orders and projections to reach $600 million in ARR the following year. To date, the company has raised approximately $380 million, and its most recent funding round in 2023 pegged its valuation at $9.1 billion. IPO prospects on the horizon The company has indicated its openness to pursuing an initial public offering (IPO) when the timing is appropriate. In a move that could reflect IPO preparations, the company appointed its first chief financial officer, Amy Shapero—formerly CFO at publicly traded e-commerce company Shopify—last year. While early-stage firms like Weka and DDN are pursuing similar goals, industry executives and analysts assert that Vast Data's technology is more developed than that of its competitors. The company's storage infrastructure combines flash storage components and other standard hardware with its proprietary software to optimise data access and movement. According to Vast Data, this architecture lowers the cost of developing and operating large-scale AI models.

In a Country Trump Says Nobody's Heard Of, Tariffs Bring Chaos
MASERU, Lesotho—President Trump promised Africa that trade would replace aid when he dismantled America's foreign-assistance programs soon after taking office this year. But here in one of the world's poorest countries , his administration is slashing both. Trump, who publicly disparaged Lesotho as a place 'nobody has ever heard of,' has threatened the tiny southern African country with 50% tariffs, among the highest rates proposed for any single nation or territory. Lesotho's garment exporters are already closing up shop in the face of dwindling orders, while other countries with more diplomatic resources rush to secure new trade deals with the White House. Lesotho's government declared a state of disaster in July as Trump's looming tariffs devastated the country's textile industry. The landlocked nation of 2.3 million people has prospered under a 25-year-old American trade program that granted duty-free access to the U.S. market to dozens of African countries. 'We took advantage of the trade concessions, being a small country,' Mokhethi Shelile, Lesotho's trade minister, told The Wall Street Journal. 'I did not expect for that to be a reason to be punished.' The garment industry is the largest private employer in Lesotho, which has an annual gross domestic product of just $2.3 billion. The U.S. accounts for nearly 20% of Lesotho's overseas sales, including clothing from brands such as Levi's and Reebok, and stores such as Walmart. Although the 50% tariffs are on pause, orders have dried up, production lines have shut down and workers have been sent home. The White House and the U.S. Trade Representative's office didn't respond Thursday to requests for comment. The disaster declaration has allowed the government to quickly reroute funds to programs aimed at youth unemployment and economic stimulus, including the waiving of fees to register companies and the creation of a fund to support new businesses, said Shelile. By imposing tariffs, Trump appears to be sidestepping the African Growth and Opportunity Act, which allows 32 African countries to sell some 1,800 products in the U.S. duty-free. The law expires this year, and, with Trump wielding tariffs as the foundation of his international economic policies, most experts don't expect the Republican-controlled Congress to renew it. Shelile says a lobbying group that purported to have access to prominent members of Trump's family asked in a virtual meeting for $1.5 million to campaign for tariff relief. He didn't identify the lobbyists. 'They wanted the money immediately, and they didn't want to guarantee results,' Shelile said. Lesotho declined the offer, he said. Shelile said he is in talks with the Office of the U.S. Trade Representative, pushing for lower tariffs. Ever Successful Textile, a Chinese-owned factory in Maseru, Lesotho's capital, employed 650 people before the tariffs were announced, with 80% to 90% of its orders destined for the U.S. By the end of July, Ever Successful's payroll had plunged to 90 workers, who were finishing up one final order—black exercise pants for the American market. Lesotho's winter was in full swing, and the workers, most of them women, huddled in a corner of the cavernous factory in hats and coats, some wrapped in blankets. 'Normally, it's too hot in here,' said Malefetsane Phahla, the human-resources manager. 'When we're done with this order, it means we're going home,' because the company operates on a 'no work, no pay' basis, he said. This week, Lieketseng Billy, 44, and a few dozen other women waited outside the Quantum Apparel factory in Maseru, hoping for work. In June, Billy was laid off from her sewing job at Ever Successful. Now, she is struggling to make ends meet. 'It's been very difficult,' she said. 'I didn't save anything when I was working; we earn just a little sum of money.' Textile factories typically pay minimum wage, which rose to the equivalent of about $168 a month earlier this year. Billy, a single mother who has been working in Maseru's textile factories since 2001, is absorbing a double-blow of tariff threats and aid cuts. She's HIV-positive, and for years she has received six months' worth of antiretroviral medication at a time from a U.S.-supported clinic. But when she went to pick up her medication in early June, she was given just a three-month supply. 'They told me when I come back, I should expect to maybe get a month's medication or even weeks,' she said. 'The situation is really bad at home,' Billy said. 'We don't have food. Next week, my daughter is going back to school and we need to pay school fees for the third quarter. I don't know where the money is going to come from.' In Lesotho's mountainous rural areas, children sometimes attend school in community churches, which are the largest indoor spaces available in many villages. Different grades sit in different corners, facing different directions, trying to listen to their respective teachers. In other communities, children attend class under the open skies, with lessons often cut short by rain or cold. American-funded school buildings with roofs, classrooms and bathrooms were at various stages of construction when Trump gutted U.S. aid programs funding the work. For the past two years, students ranging from age 6 to 15 at the Khama-Khamane Primary School in Qabane have taken their classes in a small stone church hall left roofless by a storm. In September 2024, the U.S. Embassy in Maseru said it would pay for a new schoolhouse in Qabane, but had only disbursed about half of the pledged $9,000 before Trump ended the funding, said Cheletsi Lefa, the school's principal. The school's 47 pupils continue to attend classes in the roofless church hall while Lefa searches for funding to finish the new building. 'We are going to every corner we can reach to get funding,' he said. 'We are leaving no stone unturned.' A program run through the U.S. Embassy promised to pay for a new schoolhouse for the Khama-Khamane Primary School, but it had only disbursed about half of the pledged $9,000 before Trump ended the workers on their lunch break outside the Chinese-owned Ever Successful factory. Outside of textile factories in Maseru, the newly unemployed are increasingly anxious. Mamotipi Masitha, 31, has been working in Maseru's textile factories since 2015. Her job supported herself, her husband—a driver who is currently unemployed—two young children and her sick mother. But she wasn't able to save anything on her minimum-wage pay, and in June, she was laid off along with the rest of her factory's workers due to the tariffs. 'I don't know how I'm going to be able to take care of my mother and kids,' she said outside a still-operational textile factory, along with hundreds of other women seeking work. 'I live on handouts from people to help us eat every day,' she said. 'I would love to ask Trump, please lower the tariffs so we can get our jobs back. We have families to take care of.'
