    Phoronix: NVIDIA VDPAU Performance Metrics On Ubuntu 14.04 Linux

    It's been a while since last running any video acceleration benchmarks at Phoronix so this week we're running a fresh set of VDPAU (Video Decode and Presentation API for Unix) benchmarks with NVIDIA's official driver plus for AMD Radeon hardware using the Radeon VDPAU state tracker support.

    why dont use 340.17 on lastest test, 340.17 launched on 2014.6.9

      No power consumption test when playing back through xvideo

        Because this testing was done prior to that driver being out... Since been out in Russia for more than past week, etc.

          From a power perspective is 20-30% GPU usage during acceleration worth dropping CPU utilisation by about 6%.

            Can we see the power consumption numbers for the open drivers? Intel's is certainly mature, but what about radeon and nouveau?

              I thought that nVidia hardware had a dedicated chip for video processing.

                Still waiting for passively-cooled Maxwell card...

                  Ditto. My passively cooled GTS 450 will have to do until then.

                    As was already said, it would be useful to test power consumption with software decoding. Test various presentation methods - vdpau (just the presentation part), opengl and xv. The comparison between each of these and hardware decoding would be really nice to see, so we'd have an accurate picture of how useful hardware decoding is. Not necessary to test all those GPUs, just maybe one low-end, one mid-end and one high-end.
