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.

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.

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.

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.

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.

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.

    1200 with A320 + GTX 1050ti perfect family pc or sff media pc I'm very impressed. Thanks AMD for some competition Reply

    They actually are releasing their APU's at the same time, so if you want cpu+igp you can buy their new APU's. Reply

    Could you add an overclocking section? I've been seeing the 1200 overclock well, and that could definitely close the gap with the i3's Reply

    In the plans, maybe Pt 2 next week after finishing the 1300X. Reply

    Yey! Reply

    "M." You're missing an "m" at the end of your username, T1beriu. ;-) Reply

    Awesome! I think overclocking is one of Ryzen's strong points, and it doesn't seem to drive up power consumption too much, because you can hit good clocks on stock voltage Reply

    Or, maybe we could see what happens without being kneecapped by the absurd JEDEC RAM setting. Reply

    Thanks, can only second this request! Pls, pretty pls, do include the overclocked benchmarks for gaming not only with high-end cards like GTX1080 but also the RX470 that you have in there currently. Reply

    The Blender graph seems to be wrong for the 1300X, beating the 1500x by 500 seconds seems excessive. Reply
