Which processor to encode x265 4K ?

[Atak_Snajpera]

So everything is ok then. Activate 3rd server and see if cpu usage goes up.

Hi
I did have to fiddle aroud to get distributed encoding to work and while doing that I did not set the process priority correctly. After setting it to normal the usage is mostly 100%.
thx

Muuuhahahaa !
Still so much improvement above the 3970, unbelievable.

What? Twice the price, twice the number of cores, 18% perf increase.

If its not a saturation/thread utilization issue, i wonder were the bottlneck is? Cache/ram bandwith?

I suspect that 5 instances of x265 encoding 1080p at the same time might not be enough for constant 100% cpu usage. If you overclock 3990X to 3.7 GHz then you should get extra ~50% vs 3970x.

Could be the OS. Most versions of Windows 10 only allow for 64 threads in a single processor group.

I think that 5 instance for x265 1080p encoding can't saturate 128 thread. Perhaps time for update at 8 instance or even more with this really particular CPU. Even 3970x with 64 thread seem have problem. In good multithreaded application like cinebench, you have 100% improvement between 3950x and 3970x.

The simplest solution would be reduction of ctu size from 64 to 32.

Or someone could test it on Linux, as it doesn't have the issues that windows does when it comes to high core count CPU's, even with "enterprise" edition it still has problems accessing all that power properly.

[Nintendo Maniac 64]

It could additionally be interesting to test it on normal non-enterprise Windows 10 but with SMT disabled.

[NikosD]

Summary:

Someone with access to a 3990X reviewer/ tester could ask for benchmarks using:

1) Windows 10 Pro

2) Windows 10 Enterprise

3) Linux

4) SMT disabled

And "good multithreaded application" or maybe its more suted to call it calculations, are better of running on an GPU.

Yes that could be the case. But not sure about the practicality of that scenario... In one of the reviews I read is that they reached a maximum of 3.6Ghz for all core under load, that with a 280mm AIO and pullng 650W from the wall.

Yes I read that article as well, and alot of others. It's still a guess game of why the resaults in that benchmark screenshot posted are the way they are.

3990X is a very cool CPU, but tbh its not a good buy for a workstation CPU *. Look at the benchmarks, you get good performance scaling in very few applications, 3970X is faster in quite a few cases cause of higher clock speeds and the applications were the scaling is good like in cinebench, yeah I rather just get octane and 3x 2080Ti if I were an c4d user...

* in general that is, iaf you have workloads were this makes sense for you, then yeah good for you.

I would have thought that thermal restrictions of these 9-die monsters would have capped any progress above the TR3960X around 5..10% per generation, so I am positively surprised by these +18% at the same 280W TDP.
(Price blanked out by me of course.)
I see the TR3990X base clock significantly limited to 2,9GHz for that reason...
(TR3960X was 3,8GHz, TR3970X was still 3,7GHz)

Well, maybe a bit unfair to compare multi-die CPUs against single-die CPUs anyway, but the race is on.
For bigger dies the manufacturer loses the bet against failures more often.
Yields of smaller dies seem more rewarding.
The best bet seems to be after the race: to compile a CPU out of the smaller die survivers;-)

Q6600 was also a multi-die CPU.

I was able to benchmark my new R9 3950X system against my E5-2687W v2 in x265 using the settings I've been playing around with for high image quality encodes. Both are running stock clocks.

x265 version:

x265 [info]: HEVC encoder version 3.1.1+1-04b37fdfd2dc
x265 [info]: build info [Windows][GCC 9.1.1][64 bit] 8bit+10bit+12bit
x265 [info]: (libavcodec  58.53.101)
x265 [info]: (libavformat 58.28.101)
x265 [info]: (libavutil   56.30.100)
x265 [info]: (lsmash       2.16.1)

x265 options:
--pools 4 -F 1 --crf 16.0 -p veryslow --no-sao --aq-mode 1 --aq-strength 1.15 --vbv-maxrate 25000 --vbv-bufsize 25000 --level 5.0 --keyint 125 --open-gop -D 10 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1

The source is a piece of a 1080i60 concert blu-ray that was restored to 1080p25 (1920x1080). I encoded the same 2500 frame segment multiple times and measured the time to encode. Four simultaneous encodes will effectively saturate the E5-2687W v2. It took an average time of 24001 seconds to encode the 2500 frames (four simultaneous encodes) on the E5-2687W v2. That gives a combined fps of the 4 simultaneous encodes of 0.417 fps. Four simultaneous encodes will hit 55-60% CPU on the R9 3950X. It took an average time of 7191 seconds to encode the 2500 frames (four simultaneous encodes) on the R9 3950X. That gives a combined fps of the 4 simultaneous encodes of 1.391 fps. Eight simultaneous encodes will effectively saturate the R9 3950X. It took an average time of 11302 seconds to encode the 2500 frames (eight simultaneous encodes) on the R9 3950X. That gives a combined fps of the 8 simultaneous encodes of 1.770 fps.

As a point of reference x265_FHD_Benchmark said my R9 3950X is ~4x faster than the E5-2687W v2 (77.49 fps vs. 19.05 fps).

TLDR / summary:
E5-2687W v2 - 0.417 fps (4 simultaneous encodes combined)
R9 3950X - 1.391 fps (4 simultaneous encodes combined)
R9 3950X - 1.770 fps (8 simultaneous encodes combined)

Hi Atak, finally getting to this build this weekend for 3900X

Is this still neccessary as I think the Jan 15 update you added x570 drivers. Doing this on a Asrock Taichi x570. Do the USB ports work after installing from an ISO updated using you latest now?

Seems there are modded drivers that will even allow for USB to work. Are these the ones you used?
https://www.win-raid.com/t4960f52-So....html#msg99977

Also will this work with IDE SATA set to AHCI mode?
This is going to be installed on a Samsung NVMe drive.

Also any tips on a dual boot Win7 and Win10

As I notice that you mention to enable CSM on Motherboards to be able to install Win7, but this noticed this at AMD site. Is this true or is much of what they are saying negligible as well?

Also not sure if Win7/10 can peacefully co-exist on an NVMe. As I keep reading that in order for Win10 install to see NVMe drive you need UEFI.

For users running the AMD Ryzen Processor with Radeon Vega Graphics, AMD strongly recommends that your motherboard firmware (UEFI) be configured full UEFI Mode to ensure optimal performance, compatibility, and stability with the Windows 10 operating system.

Best pick for x265 4k encoding, Ryzen 5 3600 or Ryzen 7 2700x? How much fps I can expect from those? How much performance I would get if I go for Ryzen 7 3700x?

3700x i quite a bit faster then 2700x, maybe about 30-40% cause of much better avx performance that was pretty limited in Ryzen 1000 and 2000-series. So i would say its worth the money.

How fast will it be? How long is a piece of string?

[The42]

Between Ryzen 7 2700x and Ryzen 5 3600, which will give better performance? I have no clue about x265. I have to rip my 1080p and 4K BD collection.
