But equally x265 likes to refer to MSU comparisons when the results make x265 look good: http://www.x265.org/
An x265 post referencing another paper which says HEVC outperforms AV1. The post insinuates AV1 might not be royalty-free. Reads like an attempt to spread fear, uncertainty, and doubt: http://www.x265.org/excited-av1-closing-doors/
MSU actually in the meantime updated their description. According to them they used a more recent version – see the Facebook comment thread below the streamingmedia.com link you shared.
But indeed it's a little bit ironic for someone advocating for HEVC to be concerned about patent royalties and licensing.
Thanks for the heads up. I didn't see those Facebook comments because Firefox's tracking protection blocked it (which in general is what I want). The x265 team really should add an update to their blog post to explain that MSU corrected the version number error.
30% smaller than h26_4_ is an often heard statement. If you know how much more efficient h265 is in comparison with h264 you can do the math :)
At transloadit we’ve been testing the reference implementation but to encode a video it’s about 20x slower than h264 still :) there will be many improvements to speed up but it’s expected to remain a lot slower (up to 4x as slow) or so I’ve read.
Probably meant to emphasize the 4 instead of h265 (since the parent they responded to mentioned h265 not h264) but used markdown instead of HN formatting so instead of 4 got _4_.
Current reference implementation's encoding speed is much worse.
That is definitely going to change when real optimized encoders are written, especially since all the major CPU/GPU manufacturers are part of the Alliance for Open Media.

h26_4_? What do the underscores mean (excuse my ignorance).

Just emphasizing the 4.
In markdown that would put the 4 in italics, where it's not supposed it still works as emphasis, but can be a bit confusing.
Pseudo-formatting for emphasis. If the page was markdown it would be bold/italicized.
It's not more effective technically, or perhaps only slightly in some metrics. In some ways it's much worse, like encoding speed.
People like it because it has better licensing.
