Deliver High Quality High Performance HEVC via Intel® Media Server Studio

Table 10A Encoding Speed of 4:2:0 10-bit UHD1600p test set on Media Server Studio HEVC Software Codec in TU1, TU4, and
TU7 modes. For reference the average Speed of HM14 Encoder for this test set is .011 fps.

As can be seen from Table 10A-10B the encoding speed of TU4 mode is around 7.2x of that of TU1 mode,
and that the encoding speed of TU7 mode is 2.6 times that of TU4 mode. In other words TU7 mode
reflects an overall speed of around 19 times that of TU1 mode. Also, since TU1 (for 4 core multithreaded
coding) is typically around 98 times the speed of HM, TU7 reflects a typical speedup factor of around 1700
over HM14!
A side-by-side comparison of encoding speed of different TU modes and for the 2 different resolution test
sets is shown next by the bar graphs of Fig. 15B.
