There were questions left unanswered with the TITAN, namely the mystery surrounding the missing SMX. The GTX TITAN had 14 out of a possible 15, much the same as the pro grade Tesla K20 the TITAN is based upon. Whether this was due to yield issues or NVIDIA rationing power we cannot say but the GK110 has to date always shipped with one SMX disabled. This has changed with the GTX 780 Ti because it serves up a full complement of SMX making the GTX 780 Ti a 'full fat' GK110.
