Have you tried the same tests on stock clocks? |

Noone runs a Skylake X series on stock clocks, that would be a waste of those CPUs, since they OC extremely well. As such any tests on stock really don't tell you anything useful.
For the question at hand, yes, AVX512 can run overall cooler then AVX2, because it does twice the work in the same time, or needs less time to do the same work, which means the AVX units are overall less busy, and don't heat up as much, since software like x265 isn't pushing pure AVX512 load, it still has loads of other things to compute.

Thats generally how all SIMD speedup works, you make it spend less time in typical DSP functions, which are easy to optimize, so the overall process runs faster.

If those crashes and unstability occur at stock settings, then he can be sure that it's not related to hardware issues. |

The Ryzen 9 3900X 12C/24T was already too fast, faster than any Intel desktop processor.
But the Ryzen 9 3950X 16C/32T is even faster, a lot faster. But you can always wait for the Threadrippers that will be released this month. (if you can afford the price premium)

It's looking good. Can you give us more details on that graph? Like what resolution / settings were used in handbrake?
Personally, I want to see how the 3960X and 3970X compare before buying something. I presume reviews will drop by the 25th when they all go on sale though I don't plan to be a day 1 buyer anyhow. |

So based on their picture in the review they're taking a 2160p60 input clip and converting it to 1080p30 (x264) using the "Fast 1080p" preset in Handbrake 1.2.2. I'm guessing the x265 test is also a 1080p encode.
Edit: This is probably not correct. Last edited by Stereodude; 16th November 2019 at 17:41. |

By reading almost 10 reviews of Ryzen 9 3950X today, I can clearly say that this particular mainstream desktop CPU is the best processor of AMD and generally of x86/x64 platform of all time.
It's the fastest single-thread CPU of all Intel and AMD processors and the fastest gaming CPU of AMD ever (still Intel has a slight advantage for games at 1080p) The multi-thread performance is most of the times better than the 18 core Intel HEDT and a lot faster than second generation 16 core Threadripper. All of that using the same power consumption of 9900K (~140W in all core turbo real performance) which has half cores (!) - only 8 - making 3950X an extremely efficient processor. You can even drop the TDP (base frequency) to 65W instead of 105W with a performance loss of 10% - 15% All of those with 750$. AMD at its best after many, many years.

^^ I'm SUPER impressed with it.
I have a 9900k at work and the improvement relative to this may get me to upgrade from my 7700k at home, especially with me getting more interested in SVT AV1 testing 16 cores / 32 threads is perfect for x265 as well, especially all in 1 NUMA node.

3980x (48C/96T) and 3990x (64C/128T) will be seen by windows as 2 numa nodes unless you disable SMT.

Yes 48T and 64T will be seen as single NUMA by windows. Higher number of threads will give you extra node in task manager.

Well if anyone here has a Zen 2, aka Ryzen 3000 series chip, they should run the benchmark Sagitare created and post their results there. That way we can get some real world numbers, and not the canned crap that benchmarking sites use. Though the exe files need to be updated as they're over a year old now. I honestly wish all sites would do crf 20 slow, then slower, slowest and placebo. No one uses the settings they benchmark with so the results they produce are useless.

So, no idea what settings they're using, but it's definitely not what's shown in the screenshot. |
