Maybe the additional DSP+GPU may help:
TMS320C64x+ DSP for accelerated video and audio decoding, and an Imagination Technologies PowerVR SGX530 GPU. It also says (520 MHz up to 720p @30 fps) for DSP but then a combination of CPU+DSP maybe able to handle higher resolutions.

The GPU on the pi is able to drive a 1080p@60hz display. You can play video at this resolution if you are using the hardware codec support.
Unfortunantly this does require a binary blob driver loaded by the boot process to work, but while this isn't good, it's no worse than anything else in the space.
