TechInsights did say that it spotted changes to the circuit floor plan on the Kirin 9020 that enhances the new chip’s performance and efficiency. The die of the Kirin 9020 is 15% larger than the size of the Kirin 9010.
“The Kirin 9020 processor is not a dramatic redesign but rather an incremental improvement over its predecessor, the Kirin 9010. This approach suggests HiSilicon’s focus on refining its existing designs while leveraging SMIC’s capabilities in advanced semiconductor manufacturing,”-TechInsights
TechInsight’s discovery shows that Huawei and SMIC are having a hard time being able to follow up on last year’s shocking introduction of the Mate 60 series which was powered by a Kirin chip supporting 5G for the first time since 2020’s Mate 40 line. The U.S. changed its export rules in 2020 so that foundries that use American equipment to produce chips were banned from shipping advanced silicon to Huawei.

Qualcomm obtained a license allowing the San Diego-based chipmaker to ship Snapdragon APs to Huawei for the P50, Mate 50, and P60 flagship lines. Qualcomm was given that license by the U.S. Commerce Department because it tweaked the chips so they couldn’t be used with 5G airwaves. The U.S. has been trying to keep advanced chips, including those that support 5G, out of the hands of China’s military.
At the same time, the U.S. and Dutch governments have prevented Chinese firms from obtaining the Extreme Ultraviolet Lithography machines required by foundries to manufacture chipsets using a 6nm node and lower. To put it simply, a lower process node typically means that smaller transistors are being used. That allows a chip to have a higher transistor count (the number of transistors inside a chip) and a higher transistor density (the number of transistors packed into a specific area of a chip). The higher a chip’s transistor count, usually the more powerful and efficient that chip is.
