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

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.
- voltagex_ 9y agoAre there any GPU x264 encoders that don't look like garbage compared to ffmpeg -c:v libx264 -preset veryslow -crf 18?
- paulmd 9y agoNo, 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.
