New advanced Benchmark

[zurv]

Here is the auto benchmark run on (windows 10 x64)
i9-7980xe @ 4.7 (with AVX offset of 12 and avx512 of 15)

I'm still playing around with the offsets. But 18 cores + avx. stuff gets HOT (mainly the VRMs)

With an all core turbo clock@4.7 GHz you are approaching a 600W power consumption.

Have you delidded the CPU ?

What is the translation of AVX offset of 12 in clock speed ?

I'm assuming that you have a good liquid cooler in order to go that high.

Every offset reduces the clock by 100MHz, so thats 1200 less in AVX2 mode.

oddly the 7980 is ez'r to cool than the 7900 (i have that too), the die is much larger on the 7980. Yes, i delided but it wasn't as helpful as with other CPUs (maybe 5C drop)

The issue with the AVX stuff (and 512 even more) is the power draw. Cooling the CPU isn't a problem, but so much power is going through the CPU package and VRM.. ugh. (I have a mono block too.) (Mesh is a problem too as the jacks up power usage.. normally i'd want to run it at 32 (default is 24.) But AVX + higher mesh is monster power/heat.
Also, quick stuff (even this benchmark) is fine. The hard part is something that will be stable for a long time. Doing a 4k video (game capture lossless) for 30min in x264 is still 2-3 hours. (hrmm.. video that no one really look at.. and YT totally re-encodes to pooo quality.. so maybe i shouldn't be using "very slow"... )

I wonder how much faster avx is vs not using it. Ie, over 18 cores I'm losing over 18gigs of speed when using avx. I'm assuming that it is worth it.

(also, the default speed for the 7980 is 2.6ghz. It OCs really well. Most people are getting 4.5-.49 on the OC. AVX is a problem, but most don't use that. That said, the new Time Spy 4k 3dmark test does.)

If you do not care about AVX performance then maybe you should just have bought ThreadRipper 1950x for 2 times less. In non-AVX tasks difference between those two is not big.

[zurv]

that is a silly reply. One could just have the encoder not use avx. clock to clock intel is faster and there are more core on the 7980. (also the 7980 OCs much higher than the threadripper too. So more cores, clock to clock faster and faster clocks.) perf matters more than cost. Other than encoding nothing i do uses avx. So even for single core usages this CPU is better for me than threadripper. (the 7980 OCs just as well as the 7900 (which i also have) ... well.. other than avx )
AVX 512 is a big deal (or so i'm told ) the i9s are the only desktop CPU with it. I'm not fully clear by that is but i haven't looked into it much.

[Atak_Snajpera]

clock to clock intel is faster

AMD 1 core+SMT=Intel 1 core+HT

AVX 512 is a big deal (or so i'm told ) the i9s are the only desktop CPU with it.

You will have to wait another 10 years to see decent support in apps for this SIMD instructions. AVX-512 for now is just a placebo.

AVX512 is simply not existent and as Atak_Snajpera said in the previous post, don't expect it soon.

Anandtech.com is looking for apps leveraging AVX512 since i9 7900X launch and they didn't find any to test it.

Also, as i asked you before, do you use an AIO liquid cooler for the 18core ?

Not really impressive but good to know

So what is the current optimal bang for buck CPU to get if 95% of all use is encoding with x265 and processing with Vapoursynth? I'm unsure about the current reasonable prices because Ryzens and i7's are often quite close?

no overclocking of any kind - just a stock computer
some error messages while the auto script ran but I didn't really payed attention.

[RanmaCanada]

Anyone with a Ryzen+ want to run this bench so we can compare apples to apples? It would be interesting to see it benched properly as the review sites aren't doing x265 benchmarks justice.

Is there any way we can get the benchmark updated, as several people with Epyc machines have tried to run it, and it will not run.

[NikosD]

If it doesn't run properly for EPYC it won't run for Threadripper 2, too.

[DotJun]

Will you be adding avx512 to the benchmark?

Why???

avx512 is almost useless

Due to the similar many core architecture I guess.

Unless of course EPYC has a different problem.
