The Qualcomm Snapdragon 875 managed to beat Huawei's Kirin 9000 and the previous-generation Snapdragon 865+ in the Master Lu benchmark. While the Snapdragon 875's Cortex-X1 Super core (2.8GHz) managed to keep it ahead in the CPU department, things are a lot closer to the GPU front. The Kirin 9000's ARM Mali-G78 GPU managed to surpass the Adreno 660, which is quite impressive.

Strange leak, the X1 should easily pass 3GHz. It looks fast already but it should be able to go quite a bit faster. As for the G78MP24, we'll see in a few months where it is in terms of power efficiency.
