Is the video card encoding faster than cpu video encoding?
You know that encoders produce different output, right? That's why an encoder test must consider quality per bitrate, not just speed – this is a fundamental compromise. Every encoder is a different compromise that evolves over time. Actually many compromises, because of options, and a fair comparison requires tweaking these to bring the test subjects closer. In the case of VP9 and AV1, these options have terrible defaults, and there are no presets like veryfast as for other encoders – very easy to screw up in a comparison. Encoding is an art; decoding is not.
Of course, AV1 encoding speed is interesting in itself (since nobody has shown a reasonably fast encoder), but in order to actually test that, you have to enable the speed options…
Decoders are what makes sense to benchmark like this, because the output is identical.
