KeyShot Forum

Hi

We want to buy new machines and are doubting between the 2950 and the 2990wx processor.

Anyone tested these?

Tnx,
Per

Hi Per,

Gordon posted his result 497fps for 2990WX while the 2950x got 305 on the Threadripper 2  post

Many reviewers feel that the 2950x is adequate for most users but if it's KeyShot performance you're looking for the 2990WX is the only way to go.

Remember, it's all about the cores...

Perry (Furniture_Guy)

I'm using a 2990WX and get 465-500 FPS in the benchmark.

Hardware specs are:

AMD Threadripper 2 2990WX
32GB Memory
Samsung 970 EVO
Asus X399-A Prime Mainboard
GeForce Quadro P1000

Total cost was around 3000$ and the machine is an absolute beast.

The 2990WX should be almost double the speed compared to the 2950X.


edit: I can totally recommend the Noctua NH-U14S with two fans. Even after several dozen hours of rendering the CPU stays at max boost and at around 60°C.

Hi guys,

Thanks for the replies.
Yeah, the more cores you throw at it the better it should be.
But, I came across this review which involved the 2950x qnd 2990wx being benchmarked in keyshot (that is pretty rare).
I surprised me and leaves me doubting.
The speed increase from a 2990wx compared to the 2950x is not double...which the tester describes as being a potential software issue.

Thank you for sharing the 2990WX review. The discrepancy between product and interior mode is quite interesting. We will investigate.

looks like something related to the memory bandwith each core can use (same numbers of memory channels (4) per cpu (16c, 32c), means same bandwith, means doubling the core numbers, each core only has half the memory bandwith)

and in addition the special method memory is connected to the cores of threadripper 2:
not every core has direct access to memory.

If interior mode needs a far higher memory bandwith per core, one may see this huge differences.

Just have a look at this review: https://www.anandtech.com/show/13124/the-amd-threadripper-2990wx-and-2950x-review

If not all cores / processes needs the same memory bandwith, there may be coming a solution called "Dynamic Local Mode" at October 29th which automatically pushes the most demanding processes to the cores with the fastest memory access (shortest way)
see https://community.amd.com/community/gaming/blog/2018/10/05/previewing-dynamic-local-mode-for-the-amd-ryzen-threadripper-wx-series-processors

Using TR 2990x and it's very nice, coming from a TR 1800x. Like 420 fps I think.

Problem is temperature, with 360 watercooling it's directly 67 degrees when entering Keyshot and Rendering.
Sometimes the screen just got black and PC is shut down. Have to turn off PSU then and restart PC.
It's rendering like 32 cores with 3,4 GHz but heat or something else is a real problem on our configuration. I think shutdowns coming from too hot VRM on die MSI X399... Still trying to find out, changed case now with better airflow.

But regarding MQ and his 60 degrees after hours of rendering, I think our watercooling has a problem like too small for the big TR4 cpu...

Typically 70 degrees indicates one of the following:
- Poor contact with the CPU  (i.e. bracket isn't holding the thermal block correctly)
- Poor thermal grease distribution
- Fans fighting each other (i.e. all of them sucking in air but nowhere for hot air to go).  Usually internal case temps jump though.
- Pump on water cooling not working right

Thank you Gordon. I think the base of the cooling plate is just too small. It's tr4 compatible, but does not cover the cpu completely...  X72 and other astek coolers aren't good for tr4 it seems...

You need to cover ALL of the TR4 cpu. That is your problem. You must not be into computers [H]ard Core. Who runs any cpu with out covering the whole cpu? lol
Head on over to https://hardforum.com/ look around. We are a group of nerds.

I use the following setup:

Case:
-Phanteks Enthoo Pro with removed HDD bay
Fans:
-200mm in the front, blowing in
-140mm in the rear and top blowing out
Cooler:
Noctua NH-U14S with two fans

I'm rendering lots of 4K animations which takes several days, and CPU temp never rises above max. 61-62°C at about 22°C room temp.

Considering it's a ~3000$ machine I'm super impressed, especially compared to the Dual Xeon 6148 build for 3x the price tag.

See the attached screenshot for my temperatures. It's just 15 minutes, but the temperature doesn't raise much more, even after hours. Main reason for using air cooling instead of liquid cooling was reliability and safety.

Hi

Thanks for the many replies.

The test where I refer to also shows Keyshot having trouble scaling linearly. Something it is advertised to do.
However what we see is the 2990wx  having double the cores to the 2950x but barely double the speed.

Is this something in this something in Keyshot or the processor? Or should we wait till 'dynamic local mode' to see better cpu core usage?

Cheers

Are there any workstation solutions out there that can run two 2990WX's? If so, would Keyshot be able to utilize both processors??

Thanks,

No. That is what epic is for. It would also cut into sales.

amd epycs are server class cpus, and therefore are geared towards more durability and less raw speed. While they look like they would be quite the animal, I have yet to hear of anyone building a system with them for rendering. I would guess that the MB's and compnents are quite a bit more expensive than just building another 2990wx box. Only thing there would be the added expense of a NR license.

Yea that would be wild but like above said, only the Epyc allows that, it is a server processor. 

I'm about to pull the trigger on my new build and would appreciate any and all input on the components:

1.   AMD - Threadripper 2990WX 3GHz 32-Core Processor

2.   ASUS X399 Zenith Extreme TR4 E-ATX motherboard

3.   Noctua - NH-U14S TR4-SP3 140.2 CFM CPU Cooler

4.   Kingston - HyperX Fury 16GB (2 x 8GB) DDR4-2666 Memory

5.   Samsung - 970 Pro 1.0TB M.2-2280 Solid State Drive

6.   Western Digital - BLACK SERIES 2TB 3.5" 7200RPM Internal HD

7.   NVIDIA NVS 510 Graphics Card 0B47077

8.   Phanteks - Enthoo Pro ATX Full Tower Case

9.   Corsair - HX Platinum 850W 80+ Fully-Modular ATX Power Supply

10.   Samsung - SH-224GB/BSBE DVD/CD Writer

11.   Microsoft - Windows 10 Pro OEM 64-bit

THANKS!

As someone who has only 16GB of Ram, and wanted to buy another 16GB the other day, but the price doubled on the exact sticks I currently have. I would invest in more RAM now, you're going to want it eventually.

Otherwise, looks like a beast in the making, would love to know your final cost at the end! I am thinking about investing in a similar build.

I'd bump the RAM to 32. 16 will be riding the edge, depending on what other apps you might use. Otherwise looks like a solid build. I'm still running SSD's in my workstation, haven't made the jump the the M2 drives yet.

You might want to mirror that spinning drive, or figure a way to get a larger drive and use as a backup of the main m2 and the spinning drive.

Here's the PC parts picker build for this one I knocked up real quick. The 510 card wasn't on there, so went with the 1060 at about $80 more. But could drop to the 1050 if needed/. Total as it sits there is $3234.78   

As others said M.2 drives will really speed up using large textures and such. I am grateful I've got a couple of them on my mobo. Your mobo should have slots for them.

I have the 1950x (16-core, 32-thread) and it's currently been rendering an animation for 3 days now on all cores and the temp is at 41C... I use the enermax liquitech AIO... while I know air-cooled is possible, I'd push you toward liquid. Easy to build/install and is the best at keeping that CPU cool as far as I know. Well worth the money.

Guys,

Thank you very much for all the valuable input!

Hmm, that is pretty damn cold, Will.
My 1950x with the Noctua U14S runs at around 60C on full load. Quite a difference. I'm enticed to switch to a water cooler now. Didn't know the difference would be that big.

Hmm, I would be surprised if the temperature difference between air and aio water cooling is 20 degrees for the same workload. ???

I have a coolmaster watercooler on my i7 6700k, under load averages around 60C. In the winter, if I open my windows here in Chicago, I can get it down to 40C but really it pisses off my wife. =)

Technology (PC) related cooling is still reliant on ambient temperature, we humans can adapt  :P and machines  force majeure  :-\

plus 1 for this comment ...

Hi guys,

Running now for a month or so our new 2990wx based workstations with keyshot.
Renders incredible fast now. Working in the viewport with large models is now a delight.

Highly recommend this type of build for anyone. We spend around 3.5K/eur/exVAT on it.
So well worth the investment.

Cheers

Just letting people know if they have a 2970WX or a 2990WX and run into issues with performance not scaling properly, you can try enabling DLM from AMD or CorePrio for thread adjustment in Windows. We haven't tested KeyShot 8.0 due to some bugs we were having with it, but under 7.3 we saw a dramatic increase in performance with CorePrio enabled.

I don't want to spam our site, so we'll just leave the link to the updated look at Threadripper here, and a related thread in this forum:
https://techgage.com/article/threadripper-2990wx-performance-coreprio/

We see people coming to our site (Techgage) from these forums because of our render benchmarks with our workstation testing, so we're just keeping you apprised to some additional testing that should help people if they've run into performance issues with the two top-end Threadrippers. Be aware that CorePrio doesn't work all the time, it's still a bit fussy, and may require you to start and stop a render a couple of times for the thread manager to kick in properly.

We also added some optimizations in the upcoming 8.2 release of KeyShot that significantly improves performance of interior mode (the bathroom scene) on the threadripper.

Good to know with 8.2, should save having to flick options on and off with these extra tools.

Came across this

That is interesting. I hope this all gets sorted when I move over to a TR. 7nm 3rd gen with the IPC gains and rumors going to 40-48 cores my god people the future is looking great.

What are you db levels like , I know the Noctua are very quiet, but you didn't mention the rest of your cooling setup?

Many thanks for testing!

simply wow.

but maybe also newer KS version (8.1->8.2) may also ad a part of this  positive progress..
Or do you use still the same version?

I'm on the latest version. Maybe it ads to the speed too. Who knows - ask the devs ;)

Attached is my benchmark with the Threadripper 2990wx on the latest version of Windows 10.  Getting a solid 525 FPS. 

Specs: 

• AMD Ryzen Threadripper 2990WX 32-Core 3.00 Ghz
• ASRock X399 Phantom Gaming 6
• NVIDIA GeForce RTX 2080
• 64GB RAM
• NVMe M.2 SSD

I tested Bitsum's Coreprio utility, and with Dynamic Local Mode on I was getting 460 FPS, with NUMA Disassociator I was getting 520 FPS, and with Dynamic Local Mode and NUMA Disassocator about 460 FPS.  I'll stick with AMD's built-in Dynamic Local Mode.
