When I was using official Android 6.0.1 with driver version r7p0, I had a huge slow down when trying to play some games at 2xPSP resolution on PPSSPP. After update to a custom 7.0 ROM (my phone didn't receive official 7.0) based on official kernel released for other phones with same SoC, I got also a driver update to r15p0. Suddenly got some graphic bugs fixed and no more huge slow down at 2xPSP resolution, I had the same performance at both resolutions. But all this before 1.6 update with multithreaded OpenGL, I have a very good performance now, higher at 1xPSP than 2xPSP, but still better than before.
Take a look at some videos on YT of Exynos-based Galaxy S or Mediatek phones powered with Mali GPU, they have a poor performance running Dolphin. Just compare Exynos Galaxy S9 to Snapdragon Galaxy S9. According to Geekbench, the Exynos variant of S9 has a faster CPU, but doesn't look like it. PPSSPP isn't a good comparison base because it doesn't require as much GPU features as Dolphin, but bad drivers still affected my experience.
Yes, you're right, Mali also have poor support.
Yes, the CPU is a gem, but is castrated by the GPU. (poor drivers)
I used ppsspp on a Snapdragon 800 and flew with the native resolution of my ex device (1920x1080), an LG G2.
PS: at the moment, the best SoC to play with any emulator, is the Qualcomm Snapdragon.(from 625 to 845)
With adReno = Radeon (Know ex ATI? )
