Recently, I am trying to compare performance of GPUs between Hikey960 and Hikey970.
The result is strange to me. Any idea about it?
All test-cases are the examples of https://github.com/ARM-software/ComputeLibrary. Every value is msec and minimum in 100 times exectuion.
Hikey960 and Hikey970 ran on AOSP, TinkerBoard ran on TinkerOS using OpenCL.
It is understandable for me that Mali-G71 in Hikey960 is much faster then Mali-T764 in TinkerBoard. But Mali-G72 in Hikey970 is equal or slower than Mali-G71 in Hikey960.
It may be just a problem of software tuning.
I expected that Mali-G72 is faster because of the number of shader core.
Does anybody have idea why such result come from?
