I haven't had any troubles at all with 8 bit playback on my machine. Have yet to test 10 bit due to lack of software support.

That's because of that bolted on hardware I mentioned (the h264 decoder ASIC). If you tried playing back 720/1080p MKVs in software only mode (CPU decoding) then you'd hit the same issue as there'll be with 10bit. The Atom, for lack of a better word, is slow. The Pentium 4 about a decade ago, was just as fast, if not faster, and we all know that's not really kitted out to deal with modern video either.

Example:

The Atom is sometimes faster than the P4, but only because it's leveraging multiple cores, when you compare the results which are one core vs one core, the P4 wins. In fact the single core P4 STILL wins vs both cores in the Atom at times. The Atom is obviously massively more power efficient and wins sometimes because it's dual core, but even then it's often not far ahead, an equivalent dual core P4 wouldn't lose a single test vs Atom except for memory bandwidth, simply because Atom uses DDR2 usually.
