CedarTrail Atoms, both in D for Desktop and M for mobile incarnations are scheduled to appear in Q4 2011. You can count them as 2012 products as they will realistically ship in early 2012 and probably even later.
The new Atom platform from Cedar Trail D will have a DirectX 10.1 graphics core. There won’t be any DirectX 11 support, at least not for Cedar Trail D. The only hope that Intel is saving DirectX 11 announcement for the last moment, but this is highly unlikely.
The core will look similar to the one that you’ve seen in Sandy Bridge and it will be powerfull enough to do Full HD decoding including hardware acceleration for MPEG2, VC1, ACV and H.264. We are sure that Matroska MKV and DivX should also get accelerated but probably via third party solutions as Intel probably would not dare to support all the fun codecs.
Gaming performance is questionable but it should not be much worse than current Sandy Bridge entry level Pentium 32nm dual-core chips. You can just imagine what kind of performance Fusion chips and Nvidia can get in a year's time.
Oh, we almost forgot, it will support Blu-ray 2.0. The 2.0 profile brings picture-in-picture and online functionality to Blu-ray disc and it should require the two secondary decoders, 1GB of local storage for updates and content, and an Internet connection.
This new fancy Atom is only roughly a year away.
