Hi,

I got new xiaomi 13T pro with Mali-G715-Immortalis MC11 r1p2 and méditek 9200+.

And the speed of my program is 20% less than on my old hauwei honnor play with mali G72 MC24.

I added

#pragma OPENCL EXTENSION cl_khr_priority_hints : enable



And this improved the speed from 140ms to 110 ms but still superior to the 80ms of the hauwei.

Does using CL_Buffer with Mali-G715 could drop the speed.

hi,

Last test with all optimization. Xiaomi 13T PRO is 3 to 5 time faster than hauwei.

remove all the .wait and .flush at the end of the JNI function where you are doing your OpenCL kernel and CPU processing.
