VRAY Benchmark & CPU + GPU Scores (Updated Results)

Posted on October 24th, 2018

Chaos Groups VRAY Benchmark is an extremely popular Benchmark, as it can Benchmark you Processor as well as your Graphics Card.

It is also great for comparing GPU render speed to CPU render speed, as the underlying VRAY Render Engine can use the same Scene Data.

If you are thinking of building a Computer for 3D Modeling or would like to see what GPU does best in VRAY-RT or what CPU is best for your rendering needs, this benchmark is the way to go.

VRAY-RT Benchmark Results (GPU)

Scaling with lots of GPU is not linear anymore, as we can see here, the time with 2x, 4x, 8x 1080 Tis does not scale well.

All of these Benchmarks are tested with an i7 8700K except for the Multi GPU Benchmarks.

How to read these Scores

Lots of other Rendering Benchmarks, such as Octane or Cinebench, assign a Score to the Benchmarking Result.

VRAY though just tells you the time, that your Processor or Graphics Card took to render the Benchmark Scenes. Of course, the shorter the time it took, the better.

Because GPU Rendering Speed relies so much on various factors such as PCIE-Lanes, CPU Clock Speed and Number of Cores, it is important to note, that all of the hereĀ  listed GPU Benchmarking times were taken with an Intel i7 8700K CPU.

If you have a different CPU, it might be, that your Benchmark Score Results can be off a few seconds or even minutes, depending on your setup.

In general it’s better to get a high clocking CPU, that doesn’t necessarily need lots of Cores, to make the GPUs render at maximum possible performance.

VRAY Benchmark does not Scale well in low-time Scores

We can see this in many Benchmarks, when your hardware is just too fast and the Benchmark Result converges towards the lowest possible time one can reach, the VRAY Benchmark too does not scale well any more.

In this benchmark, I would say anything that is below 20 seconds, cannot be relied upon that well. There are things like benchmark startup time, bucket to core distribution time, and Buckets that are not split up in the end of the Benchmark, that can distort the Benchmark.

CPU vs GPU Rendering in VRAY Benchmark

Often I am asked, what is better: CPU or GPU rendering?

As always, there is no definite answer and it kind of depends on what you want to render.

The great thing about GPU Render Engines is, that you get extremely fast or even Live Feedback, and can iterate and tweak your Settings much faster and therefore more often than when rendering on the CPU. More iterations usually results in better Projects.

This though only works, if you don’t need any kind of effects that either don’t work well on the GPU or take long to prepare, like huge displacements, Motion Blur, or Meshes that are so big, they or the Scene don’t fit into your VRAM. If you have to swap to System RAM, things get slower.

There were times when GPU Render Engines were just not mature enough and lacked many of the features that CPU Render Engines offered.

But nowadays, this argument is not valid anymore. GPU Render Engines such as VRAY-RT, Octane, Redshift, Furryball and many others have reached the same level as CPU Render Engines and have even overtaken them in some instances.

VRAY Benchmark Results: Interesting Findings

There are some highly interesting findings in the Results of these Benchmarks.

CPU:

AMD Ryzen R7 1700: Take a look at how close The Ryzen 8 Core CPUs are to each other. The Ryzen R7 1700 being even faster than the superior 1700X with a higher base clock. The Same situation can be found with the Ryzen 1600 vs the 1600X with the 1600 being faster than its superior big brother.

Intel i7 8700K: This Intel 6-Core CPU scores even higher than the superior i7 8086K that is supposed to have a higher Turbo-Boost Clock up to 5GHz.

GPU:

Take a look at how the 1080 Tis Multi-GPUs scale. It seems as though the more GPUs you add, the less performance you get per GPU.

This is probably though because of how the benchmark is set up, as the Benchmark times get extremely short towards the top end of the VRAY-RT Multi-GPU Benchmark Results. If Chaos Group were to lengthen the Benchmark, I suspect the Timings would scale much better.

NVIDIA Titan V: One Titan V seems to be the same Speed as two NVIDIA 1080 Tis.

NVIDIA GTX 1070 Ti: This Graphics Card is excellent in this benchmark. It even surpasses the superior and more expensive GTX 1080.

Hi,
I have a question.
I have this set up

AMD Ryzen Threadripper 2990WX 32-Core Processor, # of logical cores: 64
GeForce RTX 2080 Ti 11264MB
Rog Zenith extreme
NVIDIA driver version: 416.34
Microsoft Windows 10 Pro
V-Ray 3.57.01

and I score 33 sec on cpu rendering time.
I don’t know why, what can it be?
Thank you very much

Omar
