According to Wccftech , the Kirin 9020 is the direct successor to the Kirin 9010 that Huawei supplied for the previous Pura 70 series. Although it was leaked that the Kirin 9020 was mass-produced on a 6nm process, a deeper investigation revealed that SMIC has not yet reached a process beyond 7nm. This means that Huawei is still forced to use 7nm technology for the Kirin 9020.
Huawei at a disadvantage to rivals because of the "weaker" Kirin 9020 chip
How Huawei Made the Kirin 9020 Stand Out
Analysis from TechInsights shows that Huawei is having trouble expanding its production due to US trade sanctions, which have prevented the company from accessing more advanced manufacturing processes from partners like TSMC or Samsung. As a result, Huawei relies heavily on SMIC for chip production, which is capable of producing chips at 7nm, or N+2, or higher.
Although SMIC and Huawei have successfully developed a 5nm process together, the yield of this process is still too low for commercial use. If this process is applied to the Kirin 9020, the chip will become expensive.
The notable difference is that the Kirin 9020 has a 15% larger die size than the Kirin 9010, which allows it to have slightly more cache, ensuring better performance than its predecessor. Meanwhile, the Mate 70 Pro+ version appears to be equipped with a chip in a similar packaging to the Kirin 9000S and Kirin 9010, with the designations "Hi36C0" and "GFCV110".
According to TechInsights , SMIC has received virtually unlimited financial support from the Chinese government and is expected to maintain its 7nm process until 2026. This makes it difficult for Huawei to compete with rivals like Apple and Qualcomm - companies that will mass produce 2nm chips. Now may be the time for Huawei to worry about its future in the technology industry.
