Snapdragon 8150 logged a score of 3,281 in the single-core test on Geekbench.
Mate 20 was launched on 16 October, alongside Mate 20 Pro, Porsche Design Mate 20 RS, Mate 20X.
The Huawei Mate 20 series will go on sale in the UK, France, Italy and UAE later this month.
The stylus looks a bit bulky, so the chances that it will fit into the device are highly unlikely.
Mate 20X could feature a massive 7.21-inch FHD+ OLED display, and Huawei’s latest Kirin 980 SoC.
Huawei is expected to launch all three versions of the Mate 20 at an event on 16 October.
