Best CPU For Rendering [2020 Guide]

Have you ever wondered what Processor (CPU) is best for rendering?

Finding the best CPU For Rendering, that is also as cheap as possible, is something you will want to do before building a new Computer for 3D Rendering, or a dedicated Rendernode/ Renderfarm.

3ds max, Maya, Cinema 4D, Blender, and many other 3D Software packages have in-built and 3rd-party CPU Render Engines that all rely on maximum CPU multi-Core Performance.

Since there are so many CPUs with all kinds of clock-speeds, core-counts, hyperthreading, and brand, it can be difficult to select the right platform to go with.

AMD Ryzen, Threadripper, Intel i5, i7, i9, XEON, Pentium, some with lots of Cores and others with high Core-Clocks.

In the end, it all comes down to raw CPU Rendering performance, that I will be measuring with Cinebench R15, the currently leading Benchmarking Software for CPU Rendering Performance.

Of course, there are lots of lists online to check cinebench points, but what is most important is how well the Performance / Dollar ($) ratio is, as spending an unnecessary amount on a CPU is something we want to avoid.

This is why I have created a Performance/Dollar ($) Table that you can sort to your liking.

This will show you the best Rendering CPU for the Money:

Now you know the best Performance / Price ratio of different CPUs.

Keep in mind, to truly find not just the best performing CPU for Rendering, but the best overall system for your rendering needs, you should also consider:

  • Power consumption: Does the CPU need lots of power and drive up your power bill?
  • Single vs Multi-Socket Systems: What is the overall system price per CPU? Many Intel Xeons, for example, are available as 2 socket systems, that might make an overall system price per CPU cheaper
  • Heat: Does the CPU get very hot? Will you need a loud and expensive Cooling Solution? Ryzen and Threadripper CPUs tend to be easily cooled
  • CPU-Cooler Price: Some CPUs such as the AMD Ryzen CPUs have a CPU Cooler included in the package already
  • Motherboard price: A cheap CPU might not be such a great deal if you need an expensive Mainboard for it
  • Number of Cores (Performance) per System: A Ryzen 5 3600 might have extremely high CPU Rendering Value but you will also need multiple of those CPUs (and therefore multiple Systems) to get to the performance of a single Threadripper 3990X

If your rendering demands are high and a single PC might not be enough, be sure to check our Guide on building your own Renderfarm.

AMD Ryzen 9 3900X vs Intel i9 9900K

I have been asked this several times as these CPUs are both extremely popular. 3900X vs 9900K. Which one is better for rendering?

So lets do a quick comparison:

  • AMD Ryzen 9 3900X: 12 Cores, Cheaper, Faster at Rendering, Included Cooler, Stays cooler – 3168 Cinebench (R15) Points
  • Intel Core-i9 9900K: 8 Cores, Slightly snappier active Working, needs extra Cooler, can get very hot – 2077 Cinebench (R15) Points

So if you put everything but performance aside it usually comes down to: Are you rendering a lot (get a 3900X), or actively work on this PC a lot (get an i9 9900K).

One of these two CPUs is usually what you would choose when building a Computer for Animation or a Computer for 3D Modeling, as they are some of the highest-clocking CPUs out there.

High Core-Counts vs high Core-Clock

Both, high core-counts and high core-clocks, will improve your rendering speeds. Having more cores is usually the best price/performance way of increasing 3D CPU Rendering Speed.

Of course, Rendering alone isn’t what you usually do on a typical Workstation. When actively working on it, be it in 3D, Photo Editing, Graphic Design or Video Editing, having high core-clocks will benefit you much more than having lots of cores.

This means it would be best to both have lots of Cores AND high core-clocks. Since CPUs usually trade off cores for clocks (because of thermal limits and power regulations) you usually have to find a middle ground between Number of cores and clock-speed, though.

Best CPU for Rendering on a Laptop

Now, all of the above are CPUs that would be built into a 3D Rendering Computer or Workstation. If you are interested in using something more mobile, say, a Laptop for Animation and would also like great CPU Rendering Speed on this, then the following List is for you:

Benchmarks vs Real World

One should be aware, that benchmarks are of course not always representative of all types of real-world workloads.

A Threadripper 3990WX (Review), for example, is extremely fast at rendering Scenes that would otherwise spend a huge amount of time in the bucket-rendering phase (The phase that is parallelized most easily).

CPU Rendering CPU Cores Buckets

When rendering Frames that don’t take very long (< 1 min), having multiple lower-end CPUs instead of one very powerful CPU is usually better. This is because you can’t perfectly parallelize the entire rendering process! 

There are lots of steps involved in Rendering:

  • Preparation time
  • Mesh exporting
  • Texture loading time
  • Cache building time
  • Ray-Tracing Tree-building time
  • Light-Cache and other GI-Caching times

.. to only name a few. These are all rendering steps that are done before the more well-known bucket rendering stage even starts.

Some of these stages might even be restricted to single Cores. And when you have 64 Cores (as in the Threadripper 3990X), 63 of those Cores will have wait idly, until these preparation phases are done.

Lots of these Benchmarks, such as Cinebench, mainly measure the Bucket Rendering Phase where a Multi-Core CPU with lots of Cores pulls ahead easily, as the underlying scenes are usually not all that complex (Read as: there is almost no “single-core” preparation time involved).

Long story short:

Make sure to analyze the type of scenes you are planning on rendering. Measure what rendering stage usually takes up the most time in one of your typical scenes. Keep an eye on your Task Manager to see if the current stage uses all Cores or only a few to find out what has to be improved.

Most CPU Render Engines nowadays show the current rendering stage somewhere in the render window like in the example below from the Cinema 4D Picture Viewer:

Hello, I have read a lot and I am not sure which one to choose ryzen 5 3600 or ryzen 7 2700x ? I will use it mainly for 3Ds Max, Photoshop, Illustrator, AutoCAD. Any suggestions would be great, thank you!

Funkyman

Would like to purchase Ryzen 3700x mainly for AE, PR, C4D. Hoped to have a better price for the CPU after zen 3 released, or at least take a 5800 for a similar price (maybe for an extra $50 – $100). But all processors have been sold after few minutes. That’s crazy!
What do you suggest? Do I have to wait for the Black Friday sale or prices will be pretty much the same or maybe zen 3 will be available?
Any chance to have a price drop on Black Friday?
Thanks!

I’m planning to start my career in Blender, Houdini, Unreal Engine 4 for Animation, VFX or green screen work.
I don’t know the terms of this field,
But can you please help for it.
I will be creating short movies where I going to create sets(Hotels/rooms), location , cars etc.. Almost everything (~90%).
I’ll use green screen for the actors.
I hope I was able to describe.

I’m planning this PC build
Ryzen 7 3700x
MSI x570a pro
Ram 32gb of 3200Mhz
256/500gb NVMe
Nvidia Rtx 2070 super
4TB Sata 7200RPM
650 Power Supply 80+ Bronze
And a decent Cabinet

I can afford to add 100 dollars only in this PC build.

Please tell me if I can go with this build for my career.
Suggestions/changes or a complete new build in the same budget would be appreciated.
Thank you so much for your help
God bless you

Bharath H S

Rspected Sir, my name is Bharath, I’m from India.I have just changed my career path to Interior Designing and planning to take up 3Ds Max with Vray and SketchUp Pro courses, I will be doing a lot of 3D designs and rendering (mostly Kitchen cabinets, wardrobes, TV units, Bedrooms and Furnitures).. I want to buy a laptop for these needs.. my budget is around 2k USD. I am confused as to which laptop to buy.. some of the options in my country are Dell G5 with AMD Ryzen7 4800H,16GB DDR4 Ram, RX5600M-6GB GDDR6 GPU and Dell G7 with i7 10750H,16Gb DDR4 Ram,Nvidia RTX2060-6GB GPU… both in my budget range… Also, I want to buy only Dell, since the after sales service is better than any other brand in my country. Please help me choose, I can’t decide whether AMD is better than Intel for softwares like 3DS Max, Sketchup Pro and Vray rendering. I also want to inform – I never play any computer games.. I cannot afford Dell workstation laptops.. Dell G5 is also a lot cheaper, it would save me lot of money..Above mentioned G5 with AMD is 1350 USD and G7 with Intel is 2200 USD. Please help. Is AMD RX5600M Graphics card better than Nvidia RTX 2060 at designing and rendering ? I am aslo confused, do these softwares use more CPU than GPU or Vise-versa ? which Laptop should I buy…… Sir your insights on these issues would help me a lot..please oblige.. Thank You.

Hello Alex – now that it is established that we need CPU based rendering, Through PC Build section of yours we got a parts list based on budget of $2,000.00, it works super.
It has suggested
AMD Ryzen 9 3950X 3.5 GHz 16 core (great)
MSI X570 Tomahawk ATX AM4 (great) &

AMD Radeon RX 5600XT-XFX Thicc Pro
Question – is it ok if we replace above with
EVGA GeForce RTX2060 KO P4-2068-KR, 6GB GDDR6, Dual Fans

Thanks / Mujeeb

Hi – I have a MacPro 2013 with a 3Ghz 8-core Intel Xeon E5. I have the opportunity to upgrade with deeply discounted 3GHz 10-core Intel Xeon E5-2690 v2 or 2.7GHz 12-core Intel Xeon E5-2697 v2.

I edit primarily with FCPX/Motion and have been building 3D multi-light/multi-sets in Motion. I also use Photoshop and Lightroom.

Is it worth the upgrade and if so, which processor should I choose?

Thanks for the help.

Hello Alex
i am on the verge of buying a PC for office.
Main objective is to get high end 3ds max ‘Lighting’ renderings done quickly for Architectural Building and Towers etc. For Lighting we use Photometrical ‘ies’ files, which tends to make the files very heavy and takes a lot of time to render (when compared to simple v ray renders).

We are thinking of the following specifications..
Intel i9 9900K Coffelake LG1151 UHD 630 in preferance to
Ryzen Threadripper 3950x ( as we think Intel will be more value for money).

RAM DDR4 32 GB PC3200 GSKILL (2x16GB) RIPJAWS x 2 nos – Total 64GB ie

500GB SSD Samsung 860 EVO +
WD 2TB SATA HDD 3.5

HP NVIDIA Quadro P5000 16GB or should it be
PNY Quadro RTX 5000 16GB (is there a major difference in price and which do you recommend)

Casing – Corsair Case 570xMirror RGB Lianli PCO 11-Dynamic Mid Tower
Power Supply – Corsair RM850x
Cooler – Thermal Take Water 3.0/360 ARGB AIO Liquid Cooler
CL-W234-PL125W-A

Of the above specs one vendor has quoted USD 3,700.00 without vat (with RTX 5000 GPU)
and 2nd Vendor USD 4,000.00 (with P5000 GPU)..

what are your recommendations ? anything which we should specifically change.
Also reading in your blog the Light Cache (that is our photometric lighting rendering) happens before bucket rendering – so does that imply more cores in our case is not a major advantage ?

Apologies for the detailed description – await keenly your reply.
Thanks so much in advance.

Hi Alex,
I am an Architect by profession,
I’m in the beginner stage of learning computational 3d software’s which has incredible meshes and poly lines and also the rendering software’s which dose hybrid rendering. In future i believe that the architecture projects with V.R coding would be a proof.
As on Average I use my pc more than 12 hours a day. I believe in durability and performance
Please suggest me a pc configuration for 2000-2500$ build or do i have to spend more on configuring pc.
thanks
