-OpenCL runtime uses 2D image with CL_RGBA channel order as the tensor storage.
-This requires OpenCL 1.2 and above.
+GPU runtime implementation base on OpenCL, which uses 2D image with CL_RGBA
+channel order as the tensor storage. This requires OpenCL 1.2 and above.
 
 The way of mapping the Tensor data to OpenCL 2D image (RGBA) is critical for
 kernel performance.
