Huawei appears to be testing Android 8.0 Oreo on the Mate 9
While Huawei hasn't announced a date for the Mate 9's Oreo update, there is the possibility that such a date will be made public next month when the Mate 10 is unveiled. The big new feature that will be available with Android 8.0 is a picture-in-picture capability that will allow users to move a live video around the screen, and even switch its orientation from landscape to portrait.
As far as the Geekbench test is concerned, there is no sense in going through the specs since the phone has been out for nearly 10 months. But we can tell you that the single-core test resulted in a score of 1846, while the multi-core score was 6379.
