The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids
by Ian Cutress on August 10, 2017 9:00 AM ESTCPU Rendering Tests
Rendering tests are a long-time favorite of reviewers and benchmarkers, as the code used by rendering packages is usually highly optimized to squeeze every little bit of performance out. Sometimes rendering programs end up being heavily memory dependent as well - when you have that many threads flying about with a ton of data, having low latency memory can be key to everything. Here we take a few of the usual rendering packages under Windows 10, as well as a few new interesting benchmarks.
All of our benchmark results can also be found in our benchmark engine, Bench.
Corona 1.3: link
Corona is a standalone package designed to assist software like 3ds Max and Maya with photorealism via ray tracing. It's simple - shoot rays, get pixels. OK, it's more complicated than that, but the benchmark renders a fixed scene six times and offers results in terms of time and rays per second. The official benchmark tables list user submitted results in terms of time, however I feel rays per second is a better metric (in general, scores where higher is better seem to be easier to explain anyway). Corona likes to pile on the threads, so the results end up being very staggered based on thread count.
Corona loves threads.
Blender 2.78: link
For a render that has been around for what seems like ages, Blender is still a highly popular tool. We managed to wrap up a standard workload into the February 5 nightly build of Blender and measure the time it takes to render the first frame of the scene. Being one of the bigger open source tools out there, it means both AMD and Intel work actively to help improve the codebase, for better or for worse on their own/each other's microarchitecture.
Blender loves threads and memory bandwidth.
LuxMark v3.1: Link
As a synthetic, LuxMark might come across as somewhat arbitrary as a renderer, given that it's mainly used to test GPUs, but it does offer both an OpenCL and a standard C++ mode. In this instance, aside from seeing the comparison in each coding mode for cores and IPC, we also get to see the difference in performance moving from a C++ based code-stack to an OpenCL one with a CPU as the main host.
Like Blender, LuxMark is all about the thread count. Ray tracing is very nearly a textbook case for easy multi-threaded scaling. Though it's interesting just how close the 10-core Core i9-7900X gets in the CPU (C++) test despite a significant core count disadvantage, likely due to a combination of higher IPC and clockspeeds.
POV-Ray 3.7.1b4: link
Another regular benchmark in most suites, POV-Ray is another ray-tracer but has been around for many years. It just so happens that during the run up to AMD's Ryzen launch, the code base started to get active again with developers making changes to the code and pushing out updates. Our version and benchmarking started just before that was happening, but given time we will see where the POV-Ray code ends up and adjust in due course.
Similar to LuxMark, POV-Ray also wins on account of threads.
Cinebench R15: link
The latest version of CineBench has also become one of those 'used everywhere' benchmarks, particularly as an indicator of single thread performance. High IPC and high frequency gives performance in ST, whereas having good scaling and many cores is where the MT test wins out.
Intel recently announced that its new 18-core chip scores 3200 on Cinebench R15. That would be an extra 6.7% performance over the Threadripper 1950X for 2x the cost.

Thanks for your reply. Hopefully the test suite can be expanded as Intel's CPUs probably also move to higher core count and IO ranges in future.and i completely understand the frustration trying to get a 3rd party to change their defaults. Cheers

It's clear to me . . . Ian is playing both sides and making out like a bandit! /sFreckledTrout - Thursday, August 10, 2017 - link
Ian can we get an updated comments section so we can +/- people and after x number of minuses they wont show by default. I'm saying this because some of these comments(the one in this chain included) are not meaningful responces. The comments section is by far the weakest link on Anantech.Nice review btw.

toms has that, indeed it's kinda handy for blanking out the trolls. Whether it's any useful indicator of "valid" opinion though, well, that kinda varies. :D (there's nowt to stop the trolls from voting everything under the sun, though one option would be to auto-suspend someone's ability to vote if their own posts get hidden from down voting too often, a hands-off way of slapping the trolls)Given the choice, I'd much rather just be able to *edit* what I've posted than up/down-vote what others have written. I still smile recalling a guy who posted a followup to apologise for the typos in his o.p., but the followup had typos aswell, after which he posted aaaaagh. :D
Ian.

Ian thanks for at least responding, I appreciate it. Please compare your review to sites like PCPer and many others. They have no problem to also point out the weak points of TR, yet clearly understand for what TR was mostly designed and focus properly on it and even though they did not test the 64 PCI lanes as an example, mention that they are planning a follow-up to do it, since it is an important point. You do mention these as well, but could have said more than just mention it by the way.Look at your review, most of it is about games. Are you serious?
I have to give you credit to at least mention the problems with Sysmark.
Let me give you an example of slanted journalism, When you do the rendering benchmarks, where AMD is known to shine, you only mention at each benchmark what they do etc, and fail to mention that AMD clearly beats Intel, even though other sites focus more ons these benchmarks. In the one benchmark where Intel get a descent score, you take time to mention that:
"Though it's interesting just how close the 10-core Core i9-7900X gets in the CPU (C++) test despite a significant core count disadvantage, likely due to a combination of higher IPC and clockspeeds."
Not in one of the rendering benchmarks do you give credit to AMD, yet you found it fitting to end the section of with:
"Intel recently announced that its new 18-core chip scores 3200 on Cinebench R15. That would be an extra 6.7% performance over the Threadripper 1950X for 2x the cost."
Not slanted journalism? At least you mention "2x the cost," but for most this will not defer them in buying the monopoly.
After focussing so much time on game performance, I am not sure you understand TR at all. AMD still has a long way to go in many areas. Why? Because corrupt Intel basically drove them to bankruptcy, but that is a discussion for another day. I lived through those days and experienced it myself.
Maybe I missed it, but where did you discuss the issue of memory speed? You mention in the beginning of memory overclock. Did you test the system running at 3200 or 2666? It is important to note. If you ran at 2666, then you are missing a very important point. Ryzen is known to gain a huge amount with memory speed. You should not regard 3200 as an overclock, since that is what that memory is made for, even if 2666 is standard spec. Most other sites I checked, used it like that. If you did use 3200, don't you think you should mention it?
Why is it that your review ends up meh about TR and leave you rather wanting an i9 an almost all respects, yet most of the other site gives admiration where deserved, even though they have criticism as well. Ian I see that you clearly are disappointed with TR, which is OK, maybe you just like playing games and that is why you are so.
It was clear how much you admire Intel in your previous article. You say that I gave no examples of slanted journalism, maybe you should read my post again. "Most Powerful, Most scalable." It is well known that people don't read the fine print. This was intentional. If not, you are a very unlucky guys for having so many unintended mishaps. Then I truly need to say I am sorry.
For once, please be a bit excited that there is some competition against the monopoly of Intel, or maybe you are also deluded that they became so without any underhanded ways.
By the way, sorry that I called you Anand. I actually wanted to type Anandtech, but left it like it. This site still carries his name and he should still take responsibility. After I posted, I realised I should have just checked the author, so sorry about that.

"Intel recently announced that its new 18-core chip scores 3200 on Cinebench R15. That would be an extra 6.7% performance over the Threadripper 1950X for 2x the cost."How do you not understand that is a dig at Intel? He's saying you have to pay twice as much for only a 6.7% improvement.
smilingcrow - Thursday, August 10, 2017 - link
The memory speed approach taken was clearly explained in the test and was stated as being consistent with how they always test.I don't take issue with testing at stock speeds at launch day as running memory out of spec for the system can be evaluated in depth later on.
Johan Steyn - Friday, August 11, 2017 - link
That is just rubbish. Threadripper has no problem with 3200 memory and other sites has no problem running it at that speed. 3200 memory is designed to run 3200, why run it at 2666? There is just no excuse except being paid by Intel.Maybe then you can accuse other sites of being unscientific?

You call Intel the monopoly and call him out for not wording the sentence to dissuade people from buying Intel. Who has the bias here? If he was actively promoting Intel over AMD or vice versa, you'd be OK with the latter, but to do neither. He's an Intel shill? Come on. That's unfair. HOW should he have wrote it so it would satisfy you?
FYI Anand is gone. He's NOT responsible for anything at Anandtech. Are you going to hold Wozniak's feet to the fire for the lack of ports on a Mac too?
