Wow, interesting result! And no way did Intel worry about AMD optimizations when compiling SVT I wonder what the comparison between cpu-tuned x265 and libaom would be like, which should tilt more in AMD's favor.

I note that the top Intel processor used has only half the cores as the top AMD, so this difference could easily be due to multithreading more than per-core performance improvements. But that in no way invalidates the price/performance delta.

Also, and AV1 encoder that's running only ~2.5x slower than a HEVC encoder! Of course, I have no idea if the output quality is similar. As always, the key metric is quality @ bitrate @ performance.
