Comparing Android Devices for PPSSPP

[whgang99]

+Hi, I'm now considering to change my phone, but I'm not sure about ARM CPUs' performances, especially for PPSSPP.

The devices I'm considering to buy are:
Qualcomm Snapdragon 425 MSM8917 (ARM Cortex-A53 MP4 1.4GHz, Qualcomm Adreno 308)
Qualcomm Snapdragon 430 MSM8937 (ARM Cortex-A53 MP8 1.4GHz, Qualcomm Adreno 505)

And I'm not sure how they compare with my current device:
Qualcomm Snapdragon 801 MSM8974AC (Qualcomm Krait 400 MP4 2.26 GHz, Qualcomm Adreno 330 450MHz)

I looked at benchmarks, but I know emulators performances differ by architectures so I'm still in dark.

I'm particularly concerned about this thread about my current phone's architecture: [http://forums.ppsspp.org/showthread.php?pid=55131] I wonder if it's still valid. My phone runs games like:
* Final Fantasy III: stable 100% speed, 30/30fps
* Harvest Moon HoLV: stable 100% speed, 30/30fps
* Crisis Core: stable 100% speed, occasional frame skips
* Tekken DR: stable 100% speed, 25~40/60fps
* Kingdom Hearts BbS: constant frame drops, occasional slowdowns
* TYPE-0: 5~7/30fps with frame skips, at best
Most games like KH:BbS, TYPE-0, Tekken 6, Monster Hunter Portable 3rd HD, GoW, Wipeout Pure, Ratchet & Clank, GTA run at unplayable fps.

Since PPSSPP is my only priority in choosing phones, I am desperate to know if those new devices can run more games at playable fps.
It'd be grateful if you could suggest how those cortex-A53 devices will run PPSSPP compared to my current device.

Edit] Okay, I was able to get to test PPSSPP on the former device. Kingdom Hearts BbS ran at 10/30fps, 100% speed at best. My question is now resolved, and for anyone else looking for a PPSSPP phone, I can tell you: cortex-A53 1.4 GHz ain't good. I'm sticking to my current phone.

ARM A53 are low power oriented cores. They are not performance oriented. The only android phones which would be close to full speed are the new Snapdragon 835 Chipset phones like the Galaxy S8. You'll still need to deal with CPU throttling issues though and Qualcomm Vulkan drivers are crap.

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.

Thank you both. I was lucky to get my current phone for very cheap two years ago, and seems like I'll have to afford pretty much to get an upgrade. For now, I'll stick to that.
