HEDT Performance: Rendering Tests

Rendering is often a key target for processor workloads, lending itself to a professional environment. It comes in different formats as well, from 3D rendering through rasterization, such as games, or by ray tracing, and invokes the ability of the software to manage meshes, textures, collisions, aliasing, physics (in animations), and discarding unnecessary work. Most renderers offer CPU code paths, while a few use GPUs and select environments use FPGAs or dedicated ASICs. For big studios however, CPUs are still the hardware of choice.

All of our benchmark results can also be found in our benchmark engine, Bench.

Corona 1.3: Performance Render

An advanced performance based renderer for software such as 3ds Max and Cinema 4D, the Corona benchmark renders a generated scene as a standard under its 1.3 software version. Normally the GUI implementation of the benchmark shows the scene being built, and allows the user to upload the result as a ‘time to complete’.

We got in contact with the developer who gave us a command line version of the benchmark that does a direct output of results. Rather than reporting time, we report the average number of rays per second across six runs, as the performance scaling of a result per unit time is typically visually easier to understand.

The Corona benchmark website can be found at https://corona-renderer.com/benchmark

Corona 1.3 Benchmark

Corona sees improvement in line with the frequency gain, however the higher core count AMD parts win out here.

Blender 2.79b: 3D Creation Suite

A high profile rendering tool, Blender is open-source allowing for massive amounts of configurability, and is used by a number of high-profile animation studios worldwide. The organization recently released a Blender benchmark package, a couple of weeks after we had narrowed our Blender test for our new suite, however their test can take over an hour. For our results, we run one of the sub-tests in that suite through the command line - a standard ‘bmw27’ scene in CPU only mode, and measure the time to complete the render.

Similarly with Blender as to Corona: the new Intel Core i9-9980XE performs better than the previous generation 7980XE, but sits behind the higher core count AMD parts.

LuxMark v3.1: LuxRender via Different Code Paths

As stated at the top, there are many different ways to process rendering data: CPU, GPU, Accelerator, and others. On top of that, there are many frameworks and APIs in which to program, depending on how the software will be used. LuxMark, a benchmark developed using the LuxRender engine, offers several different scenes and APIs. *It has been mentioned that LuxMark, since the Spectre/Meltdown patches, is not a great representation of the LuxRender engine. We still use the test as a good example of different code path projections.

In our test, we run the simple ‘Ball’ scene on both the C++ and OpenCL code paths, but in CPU mode. This scene starts with a rough render and slowly improves the quality over two minutes, giving a final result in what is essentially an average ‘kilorays per second’.

LuxMark v3.1 C++

Our test here seems to put processors into buckets of performance. In this case, the Core i9-9980XE goes up a bucket.

POV-Ray 3.7.1: Ray Tracing

The Persistence of Vision ray tracing engine is another well-known benchmarking tool, which was in a state of relative hibernation until AMD released its Zen processors, to which suddenly both Intel and AMD were submitting code to the main branch of the open source project. For our test, we use the built-in benchmark for all-cores, called from the command line.

POV-Ray can be downloaded from http://www.povray.org/

POV-Ray 3.7.1 Benchmark

POV-Ray is as expected: a performance improvement, but behind the higher core count AMD parts.

    If something is a joke - Threadripper 2920, 2970,2990 is for sure with one exception 2950
    To have much more weak threads than IF/RAM subsystem is capable handle it's a joke.
    Intels HDET despite having less cores is stil just better solution.
    Benchmarks yet another series here on this site are best prove of that.

    Intel have been milking us for years, I am still holding to my 2500k overclocked to 5ghz (their last great CPU) and my next CPU is going to be a AMD for sure. Nvidia is doing the same lately, its outrageous.

    Oh, I forgot: GREAT REVIEW, Anandtech! Cheers. :)

    Crazy right, its almost like you needed a performance product and bought it.
  • nerd1 - Tuesday, November 13, 2018 - link

    My 9900k@5.1Ghz is almost 3X faster than yours considering IPC difference. And seriously, no one's using AMD GPU anymore, either for gaming or gpu computing.
  • benedict - Tuesday, November 13, 2018 - link

    No one cares how fast your CPU is and plenty of people who are not obscenely rich use AMD GPUs.
  • nerd1 - Tuesday, November 13, 2018 - link

    He said 2500k is intel's last great CPU and I showed him a counterexample.

    AMD is indeed good if you just need many cores for budget, but that's it.
  • Aephe - Tuesday, November 13, 2018 - link

    Actually, if, like me, you're rendering on Corona (or any CPU render engine in 3ds Max) daily, AMD has the best CPU. Period. The fact my 2990WX is also WAY cheaper than the next best thing from Intel is just an added bonus for my company.
  • Spunjji - Tuesday, November 13, 2018 - link

    He's using a different definition of "great CPU" from you. His includes price/performance ratio, yours doesn't. Insisting that your comparison is more valid than his doesn't make any more sense than him doing the same, so if you're going to mock someone's post, maybe avoid the same errors.
  • Arbie - Tuesday, November 13, 2018 - link

    How do AMD's GPUs relate to the HEDT CPU market being discussed here? And seriously, can't see any point to your remarks.
