Fig. 19 shows results of TU7gacc as compared to TU7 in terms of its capability of reducing the load on the<br />
CPU. For 1080p content TU7gcac is currently able to reduce the load on CPU by a few percent from<br />
enabling CPU to be used by other applications. This is in addition to around 32% encoding speedup that<br />
TU7gacc provides over TU7 while achieving identical video quality.<br />
