The OpenGL API doesn't expose any information about the underlying 
hardware. When you use shaders, you don't know whether they are executed 
on the GPU or emulated on the CPU. But the actual result is the same no 
matter which hardware/driver you're using, the only difference will be 
the speed (emulating shaders on the CPU isn't particularly fast).
