HEDT Benchmarks: 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.

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

So this is where AMD broke our graphing engine. Because we report Corona in rays per second, having 12 million of them puts eight digits into our engine, which it then tries to interpret as a scientific number (1.2 x 10^7), which it can’t process in a graph. We had to convert this graph into millions of rays per second to get it to work.

The 2990WX hits out in front with 32 cores, with its higher frequency being the main reason it is so far ahead of the EPYC processor. The EPYC and Core i9 are close together, however the TR2950X at half the cost comes reasonably close.

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.

The additional cores on the 2990WX puts it out ahead of the EPYC and Core i9, with the 2990WX having an extra 58% throughput over the Core i9. That is very substantial indeed.

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.


Taken from the Linux Version of LuxMark

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++LuxMark v3.1 OpenCL

Intel’s Skylake-X processors seem to fail our OpenCL test for some reason, but in the C++ test the extra memory controllers on EPYC sets it ahead of both TR2 and Core i9. The 2990WX and Core i9 are almost equal here.

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

This test is another that loves the cores and frequency of the 2990WX, finishing the benchmark in almost 20 seconds. It might be time for a bigger built-in benchmark.

    "I highly highly doubt that Intel would postpone 10nm just to “shut down AMD""

    Probably right - AMD is not that big of threat in the real world - just go in to BestBuy - yes they have some game machines. a very few laptops including older generations

    That is some impressive goalpost moving that you just did *on your own claim*.

    Intel's issues have nothing to do with AMD, but they will allow a resurgent AMD to become more competitive over time. Pointing to how little of a threat AMD are *right now* and/or making up weird conspiracy theories that place Intel as the only mover and shaker in the entire industry won't change that.

    Consumer based computers is but a small portion of the market. Servers, millions of them needed every year to fill the demand needed by, well, everyone who hosts a site, government, networking farms a mile long, etc. The server market is huge and is growing almost faster than tech companies can provide. It's why I always thought Apple getting out if the server market was kind of a stupid ideal. All of the servers they ever created were sold before they were even created. I guess the margains were to small for them, greedy bastards. Why only make double the profits when you make 5x with consumer products. Seriously, an iPhone X costs less than $200 to make now, it used to be $250 but now its $200, greedy bastards. Oh, did you know it costs Apple less than $3 to go from 64GB to 128GB, ugh. Reply

    it matters what you consider as costs
    do you calculate the shipping costs,the marketing costs,the salaries of everyone involved,the making of new facilities?

    Intel isn't finished. They are still king of single thread performance. We will see if Zen 2 will surpass Intel's single thread performance. Reply

    Sadly this is true. AMD tries hard and in the most part succeeds. Intel frankly showed some kind of panic for the niche market of top end processors with that chilled fiasco of a 5 GHz CPU. This means AMD puts quite some pressure onto them Reply

    AMD have bounced back very quickly . Mostly because people are starting to accept how over priced intel have been

    I don't think branding issues is going to stop purchases of AMD chips when they are the best fit for a particular use-case, but the lack of direct access to memory for half of the cores in the 2990wx is going to keep it from being the knockout punch for HEDT that it could have been.

    Looking at these benchmark results, that has seriously gimped the performance of the 32-core TR to the point where it is slower than the 16 core in some threaded workloads.

    Sure, you can just go ahead and buy the 16-core 2950x instead, but then you're reduced back to being in 7980xe territory - albeit at a cheaper price point - but the point is, it's not the clear win that a relatively high clocked 32-core CPU probably could have been without the memory access issue.
