Some models of Huawei's Mate 50 series use Qualcomm's Snapdragon 8Gen 1 (4G) processor, while some models use the Kirin 9000S.
The reason for using the Qualcomm processor is that it is limited by the chip, and there is no way to use the Kirin chip, and Huawei has used Qualcomm chips for many models before, and it is also very reasonable to use Qualcomm chips on this generation of Mate50 series.
