I bought a xiaomi 13T pro with ARM immortalis G715 GPU and is running slow than my old hauwei honnor pro using OpenCL. I am working with android. There is few solution 1) i need to update my OpenCL code with new code. 2)nothing is done on phonne to improve OpenCL perforlmance. 3)phonne are already …

I ask the question differently. Is code writen in 2019 using C++ and ARM mali G72 need to be modified to use ARM mali immortalis G715. i read that ARM said “between the use of SVM buffer and CL buffer”. So, do i need to use SVM rather than CL_buffer ? or the difference should be not so important. …

adding #pragma OPENCL EXTENSION cl_khr_priority_hints : enable Improve the speed of the kernal execution and at the same time the multithread execution. It is not so much but i can get between 20/30% of speed amélioration. But it is still 20% slower than the mali G72 with Kirm processor.

Thanks for the answer, by the way, adding this improved the speed of the kernel. #define CL_HPP_USE_IL_KHR #define CL_HPP_USE_CL_SUB_GROUPS_KHR i check thermal using arm performance studio and i got No throttle = 100% But for the rest i do not know what to look for. xiaomi do not use all the…

I check the performance using arm performanc syudio and it look like as soon as your are using OpenCL on xiaomi it only run 4 core. But if you run only OpenGL it run 8 core. And if i run OpenCL and OpenGL at same time it only use 4 core and the kernel are even slower. By the way OpenGL performance…

It is definitly a problem with android. Compiling with different NDK toolchain i get different performance. It is an android mess with OpenCL. They do not like it. ;))

Hi, The problem for the xiaomi is that it need to be compiled whit 64bit compiler to get good performance. It was not easy to managed to do it under android but at the end i made it. All the core are running and i can get nearly the same performance ttha the hauwei honnor play. But hauwei still m…

hi, I need to apologize for xiaomi because increasing the volume of data to be processed. The xiaomi is a lot faster than the hauwei, 50% faster. And specially the CPU multithreading for (4 pthread) on my last test.

last test after all optimization. xiaomi 13T pro is really fast. 3 to 4 time faster than my old hauwei mixing GPU and CPU processing.
