Comparing Android Devices for PPSSPP

[GuilhermeGS2]

The main issue with (old) Snapdragon devices is the heat, high temperatures make the the CPU work with a lower performance than it should, some work with less than half performance. It's started to change after new chips like SD 820/821 and 835.

SD 400 series is low-end, discard the option of buying any of them, it's a downgrade. You should look for Snapdragon 820 or above, this chip can play some of the most heavy PPSSPP games like both God of War and Tekken 6 near full speed (50-60 FPS). SD 600 will give you about the same performance but with better stability and battery life.

Don't look for Mali devices, they have several driver issues.
