Texture and buffer access performance in OpenGL

Currently there are several ways to feed data to the GPU no matter of what API we use and what type of application we develop. In case of OpenGL we have uniform buffers, texture buffers, texture images, etc. The same is true for OpenCL and other compute APIs that even provide more fine-grained memory management taking advantage of the local data store (LDS) available on today’s hardware. In this article I’ll present the memory access performance characteristics of AMD’s Evergreen-class GPUs focusing on what this all means from OpenGL point of view. While most of the data is about the HD5870, the general principles and relative performance characteristics are valid for other GPUs, including ones from other vendors.
