Hi sooyeon8979

1) Adreno660 GPU wave size (warp size)

At least you can know it using VkPhysicalDeviceSubgroupProperties::subgroupSize

Looks good! You can have a try with this VK Query API.

Meanwhile, what is your exact using case? OpenGL, OpenCL, or Vulkan?  Maybe Snapdragon Profiler tool  kernel analyzer can also give you some useful info.

Thanks
