Benchmarking Performance: CPU 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.

Corona 1.3

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.

Blender 2.78

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.

LuxMark

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.

POV-Ray 3.7

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.

Cinebench R15

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.

    Find me these so-called people buying Intel HEDT CPU's (aka OG Ryzen 7's direct competition) for gaming & never for HPC uses.... Oh wait. They don't exist.
  • Haawser - Thursday, March 2, 2017 - link

    Yeah, but if you're a gamer who streams, Ryzen is waaaay better than anything Inter offer for $499. Especially if you're gaming at 4K, or going to be. Different people have different needs, even gamers.
  • Jimster480 - Thursday, March 2, 2017 - link

    Yes but no,
    Because Broadwell-E and Haswell-E HEDT platforms are in the same boat as Ryzen.

    But this is what this Ryzen 7 release is meant to do.
    Compete with the HEDT platforms, not against the "APU" chips.
    Those chips will come later, albeit with much higher clockspeeds to compete with intel.
    For now you have Intel with 10-20% clockspeed advantages in clockspeed dependent applications.
  • Meteor2 - Saturday, March 4, 2017 - link

    I hope you're right but there's no indication they will be clocked higher. AMD has access to processes which are generation behind Intel's, at least for a couple of years. We can't expect miracles.

    Lol, butt hurt? Why even bother running gaming benchmarks? You even said it yourself that ryzen wont make it to your so called grown-up workstation because if low pcie count.

    So tell me who is this $500 Ryzen chip designed for? Not grown ups running workstation, or pathetic kiddies gamers...so theyre for Wannabes?

    He literally said it is ideal to replace his aging 3770k, he gave an example of how it will be used. Try more reading and less being a turd

    Ryzen is that much more affordable that with the price difference I could have built another whole system, dedicated to running the 2 HBA adapters, thus saving on the need of 16 lanes. 40 - 16 is exactly 24, which is what ryzen has. If it was available a year ago I would have simply built two systems, offering a good 50-60% more CPU performance, double the GPU performance, with enough need to accommodate my IO needs, even if between two systems, that wouldn't have been much of an issue.

    The pci lane count is lower than intel E series chips, however it is still 50% higher than what you can get from intel outside the E series. It will actually suffice in most workstation scenarios, even if you end up running graphics at x8, which is not really a big deal.

    "you even said it yourself that ryzen wont make it to your so called grown-up workstation because if low pcie count"

    I did not say that. Not all workstations require 40 pcie lanes. Most could do with 24. I was talking about my workstation in particular, which has plenty of pcie hardware. For the vast majority of HPC scenarios that would not be necessary, furthermore as already mentioned, with the saved money you can build additional systems dedicated to specific tasks, offloading both the need of more pcie lanes and the cpu time the attached hardware consumes.

    It remains to be seen how much IO will the server zen parts have. Ryzen is not particularly a workstation grade chip, it just happens to be GOOD ENOUGH to do the job. AMD give you 50% more performance and 50% more IO at the same or better price point, and I think they will do the same for the chips they actually design for workstation.

    It looks like the 16 core workstation chip will have 64 pcie lanes, and the 32 core - a whooping 128 lanes. So intel E series looks like a sad little orphan with its modest 40 lanes... And no, xeons aren't much better, they are in fact worse, the 24 core E7-8894 v4 only has a modest 32 lanes.

    So no, while I will not be replacing my main 10 core workstation with a ryzen, because that would win me nothing, I am definitely looking forward to replacing it next year with a Naples system, and I definitely wished ryzen was available last year as I could have spent my money much better than buying intel.

    "So tell me who is this $500 Ryzen chip designed for?"

    Logic would imply it is aimed at anyone that works in an environment where they need superior multithreading performance. For instance, anyone that has bought a 6900k or 6950k, but more importantly it is for those individuals that "wanted" to buy either of Intel's multi core champs but couldn't due to ridiculous prices.

    I'd dare to make a bet there are more people that wanted to buy a 6900k than there are people that actually did. Now they can buy one and still put food on the table this month.
  • FriendlyUser - Thursday, March 2, 2017 - link

    Exactly right. I was always tempted by the 6850K, but the price of the CPU+platform was simply ridiculous. For much less I got a faster CPU and a high-end MB. I won't miss the 40PCIe lanes.
