I get the same results with that version... Of course, there's a second version, antutu x ...meant to eliminate the cheating that some use on benchmarks..
With that, the G3 shows scores in mid 30k range, in line with the M8 and S5.
Yep different benchmark apps from the same company, different results... I look at these scores as comparative tools on the same device to gauge system changes. I don't put a lot of stock on what I see from other devices.
