It&#x27;s clocked at a higher frequency, and the video codecs seem to be built in software that runs on part of the GPU that isn&#x27;t directly user-accessible (early builds of the firmware supported fewer codecs). So, the question would be if it <i>is</i> hardware limitation, or if it&#x27;s just a case that hasn&#x27;t been implemented in the firmware blob yet. Maybe it wasn&#x27;t implemented before because the hardware wasn&#x27;t fast enough to do it at the lower clock.
