Adobe Premiere Pro
Last year we tested both Adobe Premiere Pro CC 2014 and Photoshop, but we've dropped the latter from this comparison. No Photoshop benchmark we've seen puts enough stress on modern high-end workstation cards to show meaningful variation between them; the performance gap between the 2010-era Quadro 6000 and the 2014 Quadro K6000 was just over two seconds. AMD cards perform identically to NVIDIA cards in Photoshop, with no apparent difference between them.
Adobe Premiere Pro CC 2014:For Adobe Premiere Pro CC 2014 we used the latest version of the venerable Adobe Premiere Pro Benchmark (PPBM7). This test contains three components -- a PAL DVD conversion (meant as a storage test), an MPEG-2 DVD conversion, and an "Export to Blu-ray" test. These last two tests are both GPU accelerated and the modern version of the Mercury Playback Engine embedded in Premiere Pro can be configured to run in either OpenCL or CUDA mode. We ran both tests under their respective languages.
Adobe Premiere Pro still favors NVIDIA cards overall, but the performance between the K6000 and M6000 is quite close. NVIDIA GPUs are much faster than AMD cards in the MPEG-2 DVD export test, but all cards are closer to each other in the Export to Blu-ray test.
