Looks like Phoronix´s benchmark isnt able to saturate all these cores... but nevertheless.. impressive numbers for the new EPYC 7xx2 series |

Within margin of error. Do not expect miracles.

For those who are still wondering which is the fastest platform for HEVC encoding:
8K real-time HEVC encoding at 79fps with just one CPU (!) https://www.tomshardware.com/news/am...ing,40400.html

I have a question that hopefully someone can help me with.
I have two computers, a PC I built and a 2018 mac mini. Using handbrake on both, using the same settings with the same file and encoding with HEVC 10bit I get very different results. The PC uses an Intel 5820 and the Mac uses an Intel 8700. The encode that comes out of the macs 8700 is quite a bit smaller file size than the one produced by the 5820 and it also has noticeably better image quality. Why is that? I'm considering an upgrade and knowing why the file is both smaller with better quality would help me in choosing which processor for a new build.

How big is the file size and quality gap? Does one of the systems have way more cores than the other? There used to be quality regressions using frame threading, although this has gotten quite a big better in recent years.

Because AVX512 is not generally recommended, so you need to enable it manually if you want to use it. Basically you should test to see if you benefit from it or not, seems to depend on the case quite a lot.

Ok, I didn’t know it was excluded from auto detection, thanks for the info and I tested it a while back. My results showed a slight improvement in FPS, even with a negative offset, so I just stuck with it. |

Yep, that’s the reason for the negative offset. From the small amount of testing I did, avx512 still came out with slightly higher FPS even with a couple hundred mghz lower clock due to offset. Though I will admit that I wouldn’t be able to run 512 if my computer wasn’t located in a 65-70f temp room. |

I had a chance to do a small sample test and here are my results:
system: 7820x oc'd to 4.4ghz with 32g of memory. A -3 offset was used for both avx2 and avx512 as explained below. 10 minute 1080p sample on auto detect: 5.38fps 10 minute 1080p sample on avx512: 5.72fps 5 minute 4k sample on auto detect: 0.84fps 5 minute 4k sample on avx512: 0.92fps crf and slower settings were used on all samples. The odd part is that both auto detect (avx2) and avx512 needed the same -3 offset or windows becomes unstable and crash. Also, avx2 ran 5-10c hotter than avx512, which is the opposite of what I thought would happen. Results might be different on a longer sample clip, but I really didn't want to invest too much time into it since for whatever reason avx2 was pushing out more heat than what I am comfortable with. |
