The title didn't mention that the Oppo R9 Plus, powered by Snapdragon 652 is a 2016 product and is currently the only Cortex-A72 based SoC to ship side-by-side with MediaTek's Helio X25. It deserved its place in the comparison.
All phones were tested with Antutu benchmark 6.1.3, Geekbench and 3D Mark. In two out of three Helio X25 came in tops. Samsung Galaxy Note 5 scored 84449, OPPO R9 Plus scored 83928 while the Meizu Pro 6 scored 100159. Last time we checked, the Snapdragon 820 powered phones scored more than 133.000.
In the Geekbench test, the Samsung Galaxy Note 5 with Exynos 7420 scored 1487 in the single core mode and OPPO R9 Plus with Snapdragon 652 scored 1512 in the single core mode and 5190 in multi-core mode. The Meizu Pro 6 with Helio X25 scored 1925 in the single core mode and 6550 in multi-core mode. The winner was the Meizu Pro 6 with Helio X25 as it manages to outperform even the Snapdragon 820 powered LG G5 in the multi-core test. The LG G5 scored 2348 in single core test, where it beat the Helio X25 and 5412 which lost to the LG G5 and Snapdragon 820.
In the 3Dmark test Mali-T760MP8 from Exynos 7420 won with 1205, eight cores definitely do better job than the Helio X25 with Mali-T880MP4 four cores. Snapdragon 652 with Adreno 510 finished last. Meizu Pro 6 looks like a decent performer, but it will be a while before customers in Europe, US, Australia, or anywhere outside of China get their hands on one.
