2. EXA was designed years ago and does not provide the necessary infrastructure to accelerate mode advanced RENDER features without an overhaul.
Thus, you end up with SW fallbacks for certain operations which means data ping-ponging between GPU and CPU buffers which almost always ends up being slower than pure CPU rendering or pure GPU rendering. You can try the glamor support in git which should improve things going forward as glamor picks up support for accelerating more and more operations using OpenGL.

Intel has already shown that it is possible to accelerate Render well and without (slow) fallbacks.
