X264 decoding is usually done in software therefore need good cpu. CoreAVC is a very efficient decoder for any of the new codecs
Sorry, my interpretation is a bit different from yours!
Standard/Specification
H.264 is a standard for video compression, and it is wildly accepted by the industry.
Open Source Implementation
x264 is a free library for encoding H.264/AVC video streams.
Early x264 releases cause some problems with DXVA HA, but x264 project already fixed them.
There are some requirements for H.264 encoded video (no matter what encoder you use) to be accelerated by DXVA. Some of files on the Internet just do not fulfill those requirements, so they will not work on DXVA HA. And you have to use software decoder like CoreAVC. I play most of my x264 files using DXVA HA decoder with no problems. At the moment, the best DXVA HA decoder is probably from Cyberlink. Although MPC-HC is coming alone quite nicely.
To sum it up, H.264 is a standard/specification. X264 is just a open source implementation of that standard. When DXVA HA decoders and Encoding Applications become more available/compatible, you should not need to use software-only decoder. The situation now for H.264 is just like Mpeg2 some years ago.
