Keyshot Interior Rendering – Intel 6700 K vs Dual-Intel Xeon 2699 v4

Keyshot Rendering – Intel 6700 K vs Dual-Intel Xeon 2699 v4

Hi, I am Tom, one of Render Boosts technicians.

I will be your guy for today.  And I will be walking you through how I made a comparison on the render quality between one of the popular processor that is found on our personal computers and the one that we use at Render Boost.

Firstly, on my personal PC, I have the Intel Core i7-6700K which I know most graphic artist, designers, animators make use of.

I wanted to see how this processor performs with rendering Keyshot files with the one that we are using on our render farm.

So, I will be comparing the Intel Core i7 6700K processor with Dual-Intel Xeon E5-2699 v4 we are using.

You may be wondering why I decided to use Keyshot for this test. Well, Keyshot is one of the popular rendering software you can find out there. It is easy to use and at the same comes with great features to let you design and render many architectural and industrial projects.

That said,

Picking a processor or determining which processor to use can be a tedious task. But before you cough out hundreds or thousands of dollars trying to upgrade your hardware, this comparison will show you just why should go along with a render farm and save yourself some money – perhaps some extra bucks for gas or clear off some of Uncles Sam’s payments.

Before we get into the nitty-gritty of my analysis, let me state down the benchmarks that I reviewed for this comparison;



As you can see from the above table, Intel Core i7 performed really well. Considering the fact that this processor was built in 2015, you will agree with me that this result is a plus point.

On the other hand, the image below showed how Intel Xeon E5-2699 v4 processor performed with one of the benchmarks.


Round 1 – Maximum Time

In this first test, I wanted to evaluate the best quality with the least time that it took a processor to render. And also to see how each processor will perform in Maximum Time  Keyshot quality mode.

I proceeded to Keyshot official website and got a sample scene from there, then I adjusted the scene resolution to 1000 X 1000.

I then adjusted the quality mode to the Maximum Time and shifted my test time to 5-minutes.

When I started the test, I monitored the quality rendered for the first minutes.

The left image shows you what I got from the Dual-Intel Xeon E5-2699 v4 we are using at Render Boost, and the right one is what it looks like with the Intel Core i7-6700K found in my personal system.

left image: 2699-1 Minute , Right image: 6700-1 Minute


From the pictures above, I clearly saw the difference in render quality between these two processors.

I want you to note that the pictures above show the quality I got for the first minute of testing only. So, without stopping the time, I proceeded to allow the test run for the next four minutes to complete my test time which was 5-minutes.

Analyzing these images, I judged the quality from two perspectives – firstly I notice that the first image had some degree of noise specially where lights not illuminated directly, it was also clear that the processor cloud not calculate enough samples in the period of given time to smooth out the photons of lights.

Even though I may want to accept the quality of the first picture, I also noticed that those areas with glossy reflection materials had the highest amount of noise. That being said, I considered the image unfit to be used in a project.


Round 2 – Maximum Sample

Now, moving onto my second test benchmark, I looked at how many samples could be rendered by each processor in a specified time.

Before starting this test, I adjusted the quality mode to Maximum Samples and set the samples amount to 256.

Here is what I found out. During a timeout of 5:56 sec, I noticed that my personal system could only render 32 samples (right image).

After about the same timeout time of 5:56 sec, the Render Boost processor had rendered all 256 samples with incredible output (left image).

From the pictures above, you will believe me when I say the results are the same as the ones I got when I tested these processors with Maximum Time – that is, the amount of noise and the low accuracy of the light calculation on my personal PC.


Round 3 – Advance Control

For my final analysis, I went with the Advance Control quality mode.

Firstly went to Advance Control settings and chose the same conditions for both processors and then proceeded to run my test.



For the first result, the left image shows that of Render Boost‘s Dual-Intel Xeon E5-2699 v4. This processor completed the rendering at 5:30, and on my personal system could only render 12% of the image (right image).

Before I conclude this test, I want you to know that Keyshot does not make provision to utilize an interior mode. This resulted in the graphic changes in my output image.

Now, let’s take a look at how each processor performed in the rendering.


As you will see, the Intel Core i7-6700k has 4-cores, and each core has a frequency of 4Ghz. But the thing is, none of these cores will attain such speed during a normal rendering sequence.

Now, looking at Render Boost’s processors (Dual-Intel Xeon E5-2699 v4) you will notice it comes with a frequency of 2.2 Ghz But using of Intel Turbo Boost Technology increases the frequency per core to 2.7Ghz.

So to better compare their performance in a proper rendering mode, I investigated their Maximum Time and Maximum Samples for 10 minutes.

Maximum Sample

These tests showed me the acceptable performance of my personal system. And the reason my system lagged behind is the fact that it is going against a cloud rendering farm.

A Cloud Rendering farm is a highly specialized network of computers for rendering and doing technical work. And its purpose is to increase speed, efficiency and save money as well as time.

Now imagine a situation where I had run all these tests with one processor from Render Boost with a frequency of 2.2Ghz against the 4Ghz on my personal computer.

The results I got would have been far worse than what I got with the Intel Core i7.

The fact that the results I got from Render Boost’s processors outsmarted the intel core i7 is as a result of teamwork between all four processors connected together.

Even though I picked a nearly light scene in the above tests, I still got the results I showed you.

Now imagine that I wanted to render a massive project or an animation with a personal system having the same Core i7 or even lower, it will be a tormenting experience for me.

Also, if I wanted to upgrade my hardware, it’s going to cost me a few thousand dollars a year because rendering engines are regularly updated, and this means they will demand more power over time.

To save myself from all the troubles and stress in getting new gears installed, too, I can just go along with a rendering company.

Companies such as Render Boost regularly upgrade their equipment to stay competitive because in a market like this where everything evolves in a very short time (software upgrades, hardware changes etc.) you have to keep up with the trend.

With so many years of experience and after comparing over hundreds of designs from individuals and companies, I have noticed that designers who take precious rendering time to improve textures, lighting, and building proper effects on their final design end up creating valuable works.

But here is something you probably don’t know -In a business like this, time is money; it is something I cannot afford to misuse by dwelling on a single project.

That is why companies such as Render Boost are there to help you achieve the same goals as well as stay ahead of your competitors.
