Encoding Speed (fps)<br />
For UHD4K test set, <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> encoder in TU1, TU4, TU7 and TU7gacc, correspondingly on<br />
average provides 0.40 fps, 3.1 fps, 8.5 fps and 11.4 fps. This reflects corresponding speedup factors<br />
wrt HM14 (single threaded) of 100, 783, 2118, and 2850.<br />
For HD1080p test set, <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> encoder in TU1, TU4, TU7 and TU7gacc, correspondingly on<br />
average provides 2.1 fps, 14.1 fps, 37.0 fps and 48.2 fps. This reflects corresponding speedup factors<br />
