Benchmarks A comment on the recent article about the Bali release of Googles WebM tools (libvpx) claimed that one of the biggest problems facing the adoption of WebM video was the slow speed of the encoder as compared to x264. This article sets out to benchmark the encoder against x264 to see if this is indeed true and if so, how significant the speed difference really is.

I wonder about their measurement methodology. From the title of the plot, it looks like they are comparing the power consumption of the CPU (and nothing else) between software encoding and hardware decoding.

I hope I'm wrong. Otherwise, the measurement is obviously totally flawed, as they don't take into account the power consumption of the hardware encoder itself. This plot only serves as a way to say "look, the CPU is idle and can do something else meanwhile !" (which is indeed a benefit of hardware encoders).
