    The new description now further specifies that the shading engine makes workloads into processing packets which are executed across the multithreaded processing units and is assisted by co-processors, illustrated in a streamlined diagram with some new terminology.

    The old block diagram presented the layout in a slightly different way.

    Is SGX's video processing capable of encoding and decoding H.264 at 30-fps?

    Surely yes, given you haven't specified a resolution. H.264 at 6x4 pixel resolution is doable.

    Well heck, he didn't even specify an FPS target, so surely 640x480 at 0.00000001 fps is doable too! ;)

    The question is whether the 30-fps at its typical target resolutions of encoding and decoding can be done concurrently, useful for video teleconference.

    Actually I don't think that is the question at all. Videoconferencing in handhelds is almost always low resolution (due to bitrate limitations), so the implementation is a little more trivial.

    The key question is what frame size/rate can they handle, and more importantly, what memory bandwidth does the architecture require while doing it? And how much power?
