What is CINEBENCH R15?
CINEBENCH R15 is a systems monitoring service that uses specifically generated CG images and scenes to test the efficiency of CPUs and GPUs, whether on your own machine or render farm, or on cloud-based remote machines.
The images and scenes that CINEBENCH R15 works with are created using Maxon Cinema 4D, but, as Dr. Bernd Lutz of Maxon explained to me, “depending on how other programs handle details, e.g. scaling with more cores, task switching, memory handling, etc., the results could differ when you do similar tests with another program. Nevertheless, the test results you get from CINEBENCH R15 will be a good indicator which CPUs/GPUs are better or worse than others.”
So there will be differences in the scores (see below) if you are using Maya or Houdini or whatever, but essentially you will beable to identify the processors that best suit your ambitions.
How it works
Main Processor Performance (CPU)
The test scenario is designed to use all of your system's processing power to render a photorealistic 3D scene (the test scene is an extract from "No Keyframes", a lovely piece of animation by Aix Sponza – you can watch the whole fine work here).
The test puts up a number of render requirements calculated to drive any processor close to insane, with sharp and blurry reflections, area lights, shadows, procedural shaders, anti-aliasing, and so on.
CINEBENCH R15 use this scene because it makes use of algorithms that are sure to put stress on all the available processor cores.
Maxon tells us that “CINEBENCH R15 can measure systems with up to 256 processor threads.” Without making any attempt to count them myself, it looks accurate to say, as they do, that “the test scene contains approximately 2,000 objects, which in turn contain more than 300,000 polygons in total.” Of course, in high end production scenes there can be millions of polygons, but this is enough to test your system without wasting time.
The score results of this test are displayed on the CINEBENCH R15 UI as points (pts). Simply enough, more points means better performance.
Graphics Card Performance (OpenGL)
To test the GPU performance in OpenGL mode CINEBENCH R15 uses a car chase scene (created by renderbaron). This is a dense scene that pulls out all the stops. The graphics card has to display a huge amount of geometry (nearly 1 million polygons) and textures, as well as a variety of effects, such as motion blur, bump maps, transparency, refraction, environments, lighting and others (download the application, watch and see).
Performance depends on the GPU processor you are testing, and it also depends on the drivers used. The intention is to evaluate the performance across different disciplines and give a good average overview of the capabilities of your graphics hardware. The result is measured in frames per second refresh speed of the GPU (fps). As with the CPU test, the higher the number, the faster your graphics card.
Maxon provides specific technical information regarding both these test processes on the tech-page of CINEBENCH R15.
Why do we ask you to use it?
If you are testing your own machine, or if you are looking to upgrade your processors, CINEBENCH R15 offers an invaluable service. This applies to RebusFarm’s processors as much as anyone’s. That is why we ask you to send us your CINEBENCH R15 results. It helps us to maintain the high standards of service we have set for ourselves over the past years. Knowing the results experienced by our clients is all part of how we can make sure RebusFarm remains the outstanding cloud render service that its many clients know it to be.
Also, it would be a kindness to us as these results will help to raise our online presence and thus recruit more clients. As, we hope, our satisfied clients, we are sure you would want to help us find a wider audience for our service.
Thank you, vielen Dank
