Chinese version of the Reno3 Pro, which uses the Snapdragon 765G
Here’s a story you’ve heard before: a company has been caught cheating on mobile benchmark software. Rather than being limited to phones from a particular firm, the culprit in this instance is chipset maker MediaTek, meaning multiple handsets from several vendors are engaging in the practice. Its excuse? Everyone does it.
Anandtech discovered the cheating after benchmarking the MediaTek Dimensity 1000-powered Oppo Reno3 (Chinese version), and the European version of the Oppo Reno3 Pro, which is powered by the older, lower-end Helio P95.
Strangely, the Oppo Reno3 Pro’s Cortex-A75 with its two cores outperformed the Reno3 and its four-core Cortex-A77 in PCMark.
To confirm the cheating, the publication used an altered version of PCMark that can’t be identified as a benchmarking tool by systems. Not too surprisingly, the P95 scored lower: a 30 percent drop in the overall score, with up to a 75 percent difference in specific workloads.
In the Chinese version of the Reno3 Pro, which uses the Snapdragon 765G, no cheating was observed when running the benchmarks.
Examining the P95-powered Reno3 Pro’s firmware revealed a file with a list of popular applications and benchmarks with various power marks and management tweaks applied to them. This ‘sports mode’ boosts the memory controller and scheduler when the apps are running, improving performance.
Several MediaTek-powered devices, not just those from OPPO, were found to exhibit the same behavior, including the Sony Xperia XA1 that launched back in 2016, indicating this has been going on for some time. Check out the full list below.
