ARM - Mali - G78 MP14 power consumption - 30fps

Hello everyone!

I have a game that runs on 30fps and has a power consumption of 175Watts ( on NVIDIA RTX2070).

I would like to know what would be the power consumption of my game running on my galaxy s21 GPU:

ARM - Mali - G78 MP14  - (30fps)  

I couldn't find much information on the net. The only thing I've found is this:

MFC. Process FPS Avg. Power
(W)
Perf/W
Efficiency
Galaxy S21U (Snapdragon 888)  ️ Peak 5LPE 29.82 8.10 3.68
Galaxy S21U (Exynos 2100)  ️ Peak 5LPE 28.04 7.69 3.64

taken from: https://www.anandtech.com/show/16463/snapdragon-888-vs-exynos-2100-galaxy-s21-ultra/6

But as you can see it is related to the S21-Ultra.

Can I deduce that my game power cons. will be around 8.1Watts?

Thank you very much!

  • The only way to know will be to measure it; different content can have very different energy use depending on the workload and memory bandwidth consumption.

    If you are needing a 175 Watt GPU to hit 30 FPS desktop, it's unlikely that your content will be able to hit 30 FPS on mobile without substantial changes and optimization.

  • Thank you very much.

    I've forgotten to mention that I do have this optimization.

    Is there a way to overcome the physical power consumption measurements and deduce it via another way?

  • Not really - it's a "hard" problem to solve theoretically, as there are so many moving pieces (variable GPU workload, variable CPU workload, variable memory system performance,  different screen resolutions, silicon design choices by a particular chip vendor, etc).

    For high-end mobile your total system power budget for sustained use (CPU + GPU + memory) is around 3.5 Watts. You can peak around 6-8 Watts, but the device will overheat if you try that for long periods.
