overall speed of 24 to 29 times that of TU1 mode. Also, since TU1 for 4 core muli-threaded coding is
typically on average 125 times the speed of HM (range of 100 to 141 times), TU7gacc reflects a typical
speedup factor of 2850 to 3500 over HM14!
A side-by-side comparison of encoding speed of different modes and for the 4 different resolution test
sets is shown by the bar graphs of Fig. 7B. Table 3A-3D also show that the TU7gacc mode is able to reach
encoding speed of 9.5 to 14.5 fps for UHD4K content, 35 to 67 fps for HD1080p content, around 67 to 90
fps for HD720p, and 126 to 153 fps for SD/XD content.

Figure 7B Average encoding speed of all test sets on Media Server Studio HEVC Software Encoder
Fig. 8 shows another benefit of TU7gacc as compared to TU7 in terms of its capability of reducing the load
on the CPU. Thus TU7gaac is currently able to reduce the load on CPU by around 5% from around 95% to
around 90% enabling CPU to be used by other applications. This is in addition to 32% encoding speedup
that TU7gacc provides over TU7 while achieving identical video quality.
