So This is How Allwinner A80 Cheats at Antutu Benchmark…

Ever since Allwinner A80 was released, the Antutu scores did not add up with some devices getting around 30,000 points, while other devices scoring close to 50,000 or even higher. But what about 143,430 points? Now that would be impressive, and that’s exactly what Byron got in his Tronsmart Draco AW80 box, after changing a single parameter.

The screenshot above reports a Nexus 10 because he must be using one of Freatab ROM, where they often change the device name for better Google Play compatibility. Nevertheless what kind of sorcery is that? How could he achieve this?

It turns out build.prop, as a key called ro.sys.hiritsu. It’s set to 30 in the stock firmware, but if you change this to 95, some magic happens, and you get the very high score above. Byron reported his box got pretty hot with this setting, so it’s probably better not to try a high value… Hiritsu (ひりつ) is a Japanese word meaning “ratio, proportion, percentage”, and in this case It looks like it just set the Antutu cheating ratio… Manufacturers may decide to adjust it just a bit to show a very good score, but not too high or it’d look suspicious.

What happens if you remove ro.sys.hiritsu from build.prop? Freaktab member fess tried it, and the score falls down to 36,185, which should be closer to reality, and similar to the score (36,903) I got using Antutu X. Another member try to adjust the setting to 30 and 35 and run both Antutu and GFXBench. Antutu score goes up from one setting to the other, but GFXBench stays put at 476. GFXBench is a graphics intensive score, and maybe a CPU intensive benchmark, might have a slightly higher score, but certainly in the order of magnitude shown in Antutu.
