According to the reference I've circulated before we achieve a lower compression penalty but we are slower than libx265. Like I said this codec is a live project in continuous development.

The coding efficiency provided by the HEVC reference implementation (i.e. HM) gives you the "theoretical" limit a standard can achieve. Therefore understanding how far a codec is from this theoretical limit is a good indication on whether the development is heading in the right direction. Of course given the limitations of the reference implementation (i.e. no parallel processing, single pass RC, no shot change detection, etc.), it is also wise to compare with other practical implementations.
