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:
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.
HTH, Pete
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.
