The OnePlus 8 Pro gets featured on the AI Benchmark leaderboard but seems to have mustered a rather mediocre score in the benchmark when compared to other flagship phones powered by the Snapdragon 865 and even some of the Kirin 810-powered phones. Leading the pack is the Kirin 990 5G in the Huawei Mate 30 Pro 5G, which is indicative of Huawei's prowess in NPU design.
