Huawei Reportedly Developing 5nm Chip Architecture for Future Smartphones
A recent report has revealed that Huawei Technologies Co. Ltd. is allegedly working on a new chip architecture that could enable the production of 5nm processors, marking a significant advancement in the company's semiconductor capabilities despite ongoing restrictions.
According to a report published by HuaweiCentral on August 18, 2025, the Chinese tech giant is developing what's being called an "N+3 architecture" that could power its future Pura, Mate smartphones, and MatePad tablets with more efficient Kirin chipsets.
The leaked information suggests the new 5nm process chip features a 125 million transistor design, with Semiconductor Manufacturing International Corporation (SMIC) expected to manufacture the component. Industry sources indicate this N+3 chip architecture delivers a transistor density of 125 million transistors per square millimeter, equivalent to Taiwan Semiconductor Manufacturing Company's (TSMC) 5.5nm process technology.
This represents a substantial improvement over SMIC's current 14nm process technology, which has a transistor density of 35 million transistors per square millimeter. The reported advancement would constitute more than a 250% increase in density, potentially enabling Huawei to compete more effectively with flagship Snapdragon and Dimensity processors.
Despite the technological progress, analysts note that Huawei's chips may still lag behind international competitors due to restrictions on accessing advanced chip-making technologies. However, the development would represent a significant upgrade from current Kirin processors and could deliver enhanced performance for the company's devices.
Huawei has not officially confirmed the development. The company has recently begun displaying chip details in its devices' "About Phone" sections, suggesting improved processor supply chain stability. If the timeline holds, the alleged 5nm flagship chip could debut by late 2026, potentially reshaping Huawei's competitive position in the premium smartphone market.
