Huawei presented this Thursday the Mate 90 series, its new range of high-end phones, with HarmonyOS 7 and a new generation of Kirin chips developed in China. The launch comes as U.S. restrictions continue to limit the company's access to certain semiconductors and equipment used to manufacture them.
The most advanced model of the new family incorporates the Kirin 9050 Pro, a processor that uses an architecture called 'LogicFolding'. As Huawei explained, this technology reorganizes the chip's connections in three dimensions to increase processing density without solely relying on reducing the size of transistors.
The development of this technology is part of Huawei's strategy to reduce its dependence on foreign suppliers. The company, however, continues to face restrictions on China's ability to produce advanced semiconductors.
A chip designed to circumvent manufacturing limitations
The new design modifies the distribution of connections within the semiconductor to concentrate more elements in a reduced space. The solution allows for increased performance, although it also increases manufacturing complexity.
Huawei has not confirmed who manufactures the Kirin 9050 Pro. Reuters notes that SMIC, the leading Chinese manufacturer of logic chips, is widely considered to be the producer of the Kirin used by Huawei.
Richard Yu, head of Huawei's consumer business, noted during the presentation that China's capacity to produce advanced chips remains limited. The country's industry continues to use deep ultraviolet (DUV) lithography equipment, while access to extreme ultraviolet (EUV) lithography systems remains restricted.
Huawei gains ground in China
The launch comes in a Chinese smartphone market that is going through a contraction phase. Domestic shipments fell by 7% year-on-year between January and August, according to IDC data cited by Reuters.
Huawei followed a different trajectory during that period: its shipments in China increased by 13%. The company has focused part of its strategy on high-end models, a segment where component costs are also rising.
The increase in the price of memory has raised, according to Yu, about 200 dollars on average the cost of each phone. Huawei has passed part of that increase onto the consumer and the Mate 90 Pro Max reaches 9,999 yuan.
The technological pressure continues to condition Huawei
The launch of the Mate 90 shows that Huawei continues to develop its own alternatives to maintain its activity in the smartphone market despite U.S. restrictions. The company also aims to extend the 'LogicFolding' architecture to future devices.
The technological advance does not eliminate supply limitations. The ability to manufacture advanced semiconductors remains one of the main constraints for Huawei and for the Chinese chip industry, which continues to develop its own solutions in an environment marked by U.S. trade controls.
