Huawei Technologies Co’s (華為) latest high-end smartphone features more Chinese suppliers, including a new flash memory chip and an improved chip processor, a teardown analysis showed, pointing to the progress China is making toward technology self-sufficiency.
The inside of Huawei’s Pura 70 Pro was examined by online tech repair company iFixit and consultancy TechSearch International, finding components made by Chinese suppliers.
The firms also found that the Pura 70 phones run on an advanced processing chipset made by Chinese chip foundry Semiconductor Manufacturing International Corp (SMIC, 中芯) called the Kirin 9010, which is likely a slightly improved version of the advanced chip used by Huawei’s Mate 60 series.

“While we cannot provide an exact percentage, we’d say the domestic component usage is high, and definitely higher than in the Mate 60,” iFixit lead teardown technician Shahram Mokhtari said.
“This is about self-sufficiency, all of this, everything you see when you open up a smartphone and see whatever are made by Chinese manufacturers, this is all about self-sufficiency,” Mokhtari said.
The Pura 70 series launched late last month and quickly sold out.
Earlier analysis by teardown firms such as TechInsights of the Mate 60, launched in August last year, found that the phone used DRAM and NAND memory chips made by South Korea’s SK Hynix.
SK Hynix said at the time that it no longer works with Huawei, and analysts said the chips likely came from stockpiles.
The Pura 70 still contains a DRAM chip made by SK Hynix while the NAND flash memory chip was likely packaged by Huawei’s in-house chip unit, HiSilicon (海思), with each NAND die bearing a 1-terabit capacity, iFixit and TechSearch found.
This is comparable to products made by major flash memory producers such as SK Hynix, Kioxia and Micron.
“In our teardown, our chip ID expert has identified it as a particular HiSilicon chip,” Mokhtari said.
The processor used by the Puro 70 Pro suggests that Huawei might have only made incremental improvements to its ability to produce an advanced chip with Chinese partners in the months since it launched the Mate 60 series, iFixit and TechSearch said.
The processor is similar to the one in the Mate 60 series, which used SMIC’s 7-nanometer N+2 manufacturing process, they said.
“This is significant, because news of the 9000S on 7-nanometer nodes caused a bit of a panic last year when US lawmakers were confronted with the possibility that the sanctions imposed on Chinese chipmakers might not slow their technological progress after all,” iFixit said.
“The fact that the 9010 is still a 7-nanometer process chip, and that it’s so close to the 9000S, might seem to suggest that Chinese chip manufacturing has indeed been slowed,” iFixit added.
Huawei should not be underestimated, as SMIC is still expected to make a leap to a 5-nanometer manufacturing node before the end of the year, Mokhtari said.
Nvidia Corp CEO Jensen Huang (黃仁勳) is expected to miss the inauguration of US president-elect Donald Trump on Monday, bucking a trend among high-profile US technology leaders. Huang is visiting East Asia this week, as he typically does around the time of the Lunar New Year, a person familiar with the situation said. He has never previously attended a US presidential inauguration, said the person, who asked not to be identified, because the plans have not been announced. That makes Nvidia an exception among the most valuable technology companies, most of which are sending cofounders or CEOs to the event. That includes
TARIFF TRADE-OFF: Machinery exports to China dropped after Beijing ended its tariff reductions in June, while potential new tariffs fueled ‘front-loaded’ orders to the US The nation’s machinery exports to the US amounted to US$7.19 billion last year, surpassing the US$6.86 billion to China to become the largest export destination for the local machinery industry, the Taiwan Association of Machinery Industry (TAMI, 台灣機械公會) said in a report on Jan. 10. It came as some manufacturers brought forward or “front-loaded” US-bound shipments as required by customers ahead of potential tariffs imposed by the new US administration, the association said. During his campaign, US president-elect Donald Trump threatened tariffs of as high as 60 percent on Chinese goods and 10 percent to 20 percent on imports from other countries.
Taiwanese manufacturers have a chance to play a key role in the humanoid robot supply chain, Tongtai Machine and Tool Co (東台精機) chairman Yen Jui-hsiung (嚴瑞雄) said yesterday. That is because Taiwanese companies are capable of making key parts needed for humanoid robots to move, such as harmonic drives and planetary gearboxes, Yen said. This ability to produce these key elements could help Taiwanese manufacturers “become part of the US supply chain,” he added. Yen made the remarks a day after Nvidia Corp cofounder and chief executive officer Jensen Huang (黃仁勳) said his company and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) are jointly
MARKET SHIFTS: Exports to the US soared more than 120 percent to almost one quarter, while ASEAN has steadily increased to 18.5 percent on rising tech sales The proportion of Taiwan’s exports directed to China, including Hong Kong, declined by more than 12 percentage points last year compared with its peak in 2020, the Ministry of Finance said on Thursday last week. The decrease reflects the ongoing restructuring of global supply chains, driven by escalating trade tensions between Beijing and Washington. Data compiled by the ministry showed China and Hong Kong accounted for 31.7 percent of Taiwan’s total outbound sales last year, a drop of 12.2 percentage points from a high of 43.9 percent in 2020. In addition to increasing trade conflicts between China and the US, the ministry said
