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, Workstation for After Effects, a dedicated Rendernode, a Renderfarm or even a Laptop for Animation.

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 different CPU types with different 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.

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

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

Best CPU for 3D Rendering

Performance / Dollar ($): Higher is better.

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?
  • Cooling Solution: Some CPUs such as the AMD Ryzens have a CPU Cooler included in the package already.
  • Mainboard price: A cheaper CPU might not be so cheap if you need an expensive Mainboard for it.

AMD Ryzen 2700X vs Intel i7 8700K

I have been asked this several times as these CPUs are both extremely popular. 2700X vs 8700K. Which one is better?

So I compiled a quick main feature list of both CPUs:

2700X: 8 Cores, Cheaper, Faster at Rendering, Included Cooler, Stays Cooler, Slightly less-snappy active working

i7 8700K: 6 Cores, Snappier active Working, currently very expensive, needs extra Cooler, can get very hot

So if you put everything but performance aside it usually comes down to: Are you rendering a lot (get a 2700X), or actively work on this PC a lot (get an i7 8700K).

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.

But, of course, Rendering alone isn’t what you usually do on a typical Computer. 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 and power regulations) you usually have to find a middle ground between # 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:

CPU NameCoresGHzCinebench

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 2990WX, for example, is extremely fast at rendering Scenes that are less Memory intensive but does not scale linearly when rendering memory heavy scenes.

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.

Lots of these Benchmarks, such as Cinebench, mainly measure the Bucket Rendering Phase where a max Multi-Core CPU usually pulls ahead easily, as the underlying scenes are usually not all that complex.

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.

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

Hello! my question is which is better for 3d rendering max + vray next, so I understand the table published here, would always be an amd processor? I could pay for an i9 9990k or an AMD RYZEN THREADRIPPER 2920X? or some other suggestion. Thank you! Your page has been very helpful!

Hi Alex

I am really scratching my head trying to work out the best system for my workstation

The targets I want to excel at…
I am looking at creating VFX for series and feature films

– Video editing: 4K multilayer compositing / rendering with 8K capable futureproofing
– 3D modelling, multipolygon with photorealistic target for authentic looking results. I want to create believable terrain, models, 3D architecture that will blend as seamlessly as possible with live action
, for example, creating large spacecraft the looks believable close-up as well as in the distance, that my virtual camera can approach and fly into detailed interiors
planets that can be detailed enough to be able to fly down from orbit perspective to a detailed scene.
– Human / creature modelling that looks natural and real
– 3D VR real video editing in High rez and creation of 3D environments like a photorealistic game-world that can be moved around within., scenes with believable terrain, vegetation and structures.
2D to 3D conversions
Advanced audio / music creation.

Ideally I want to be able to create VFX for 4-8K series & feature films on par with Netflix Lost in Space, Star Trek Discovery , Avatar,

My software
Adobe Premiere, AFX, audition
Maya , 3DS max
Autocad [for building cities]
Building software [For building detailed housing interiors / exteriors
Cakewalk for music creation / production

So, in a nutshell what is my best option…. Intel or AMD threadripper.?

The Intel solution I have mapped out is
– Core i9-9980XE and 3 fan liquid cooling { I imagine I will need to overclock for best results]
– Asus WS X299 SAGE motherboard with its high slots / 7.1 audio
– Corsair Vengeance 128 GB LPX Black DDR4 3200MHz [8x16GB]
– Nvidia Quadro RTX 8000 GPU Graphics card.

So whats the best AMD solution.
– AMD Ryzen Threadripper 2990WX processor?
– The best mother board for this would be? – one with plenty of expansion and memory speed 7.1 Audio and capable of 128 GB Ram
– Best 128 GB Ram for the AMD setup would be?
and will the Nvidia Quadro RTX 8000 GPU Graphics card. work in an AMD environment.

Or, considering my workflow target, are there better solutions out there.

I would really appreciate your help here, so I can invest wisely.

This would be my 1st time building AMD pc I have been in intel/nvidia for many years as a rhino modeler and vray user. do you think rx580 is good for gpu rendering? or should I stick with nvidia and take advantage of CUDA?

Hey everyone,

I’m currently looking for a laptop for my schooling and also gaming. I’m going to school for Digital Sculpting so ill be using 3Ds Max, Maya, ZBrush, Photoshop basically everything. Ive been looking for months now although I’ve learned some stuff, I still unfortunately i don’t have the best knowledge in what i should get. So i need some major help Ive been looking into a lot of brands like Razer, MSI, Please help i’m willing to spend a pretty penny on one since it is my future so no problem with that, all help is appericated. 🙂

Hello every one

I am trying to build a new PC for work in rendering using vray cpu render

I wanna know if this is a good choice to build a dual xeon E5-2650 workstation and for future upgrade

Thanks

Irvanditya

Hi Alex,currently i’m confused to choose between the R5 2600 and i5 9400f, which one do you think works best for me since i will using this pc mainly for lumion, sketchup , ps and autocad while play some game sometimes. I’m planning using rtx 2060 for the gpu.

Luke

Hi Alex, really would appreciate you help. Im 3d generalist my website http://www.lukx.com and im waiting to upgrade my workstation after the new amd 7nm threadrippers hit the market. At first i was sure to get the highest model but after reading you articles im not so sure anymore. I need the CPU for many different tasks and not only rendering(but its crucial). I do a lot of modeling, poly heavy scenes, also lot of simulation (particles, cloth) and later on rendering. Im 20 years intel user so still have mixed feelings going amd path. Whats your take on this?

Abdelkrim

Hi Alex
first wanna say thanks man
I currently have I7 6700k, Ram : 32gb Trident Z 3200mhz, 2*Gtx1080; ssd 480gb corssair and I’Am looking for an upgrade
my most main used software is After effects as a motion graphic Artist and I do some vfx stuffs
and going forward using maya and Houdini
-so what should I get for the next upgrade, confused between Threadripper or I9 series or even wait for 3rd gen Ryzen,
-for Ram should i go for high frequency ram +3200mhz or not important
-ssd thinking to get 970Evo pro for system and soft
-Gpu RTX series
what is your recommended build for my setup
ps: sorry for my English
Thank you.
