It's a pretty natural consequence of how much crap Intel piled in on this release. Cache, mesh, and AVX512 all consume a great deal of power.
Contrary to what the sibling comment says, Ryzen is nowhere near Intel's performance here. Even in very parallel tasks like x264 video encoding, the 7800K (6-cores) is beating the highest-clocked 8C Ryzens by almost 6%. Comparing apples to apples, the 7820X (8C) is 33% faster than the 1800X.
That's a very good place for Intel to be overall, even if their power consumption is higher than I'd like to see. Downclocked Xeons will probably beat Ryzen's efficiency. And there may be some UEFI/microcode gains to be made here as well, both in efficiency and total performance.
The bigger problem (for the enthusiast market) is the thermals. Intel just switched from solder to TIM on the HEDT processors and it's very clear that they cannot move heat out of the package fast enough and it's limiting the total OC, which would likely reach 5 GHz a good chunk of the time.
33% faster encoding x264, at what price? Ryzen 7 1800X: $499, Core i7-7820X: $599 (+20% over Ryzen). You can also cherry-pick tests where the Ryzen gets better performance or better performance/price, and not just tests involving AVX usage. Also, in cheaper Ryzen's the performance/price gets abysmal in favor of AMD. BTW, you can compare also a $599 GPU performance encoding x264 versus that Intel CPU and see how "fast" are Intel CPUs in comparison.
No, when I encode my vidya sessions for archival I use 1440p variable-fps (60fps) NVENC H264 for the first pass at an absurd bitrate (40mbps) and then I use x264 variable-fps veryslow CRF 24 for the archival pass.
veryslow is where the magic happens. As far as I can tell that's where you start getting decent quality/compression. If I increase CRF any higher (decrease quality) then shit gets super blocky super fast. Unfortunately I haven't found a way to crush high-quality streams like that in remotely realtime, you need to record 1440p (and dump an archival stream to disk) and then transcode to 1080p since that's doable.
We haven't seen AMD HEDT yet, so comparing the 7820X to the 1800X is not apples to apples. (For starters, the former has twice the memory channels compared to the latter).
