Best Desktop For 3d Rendering

Posted on  by admin

The most interesting thing you’ll come across when looking for a Computer or Workstation for 3D Modeling and Rendering is that 3D Modeling and (CPU)Renderingare two very different workloads.

Each of them uses the Hardware of your Computer in very different ways! Before we dive in, feel free to use the below button in case you prefer to skip the theory and want to know my recommendations immediately:.

CPU Rendering uses all cores of your CPU, 100% of the time while rendering. This means if you’re using your Workstation just for 3D Rendering Images and Animations, or encoding Videos for that matter, you would be looking for a Computer with a CPU, that has as many cores as possible.

Even if these cores are clocked relatively low. The Benchmark “Geekbench” shows at a glance how CPUs become progressively worse in single-core performance the higher their core count and vice-versa.

This is because the render engine assigns a so-called “bucket” to each core in your CPU. Each individual core will render its bucket and then get a new bucket once it’s finished rendering the previous one.

Because this can be easily scaled almost indefinitely, it’s a perfect workload for distributing onto CPUs with a lot of cores.

Contrary to rendering, 3D modeling is an active working process. You sit in front of your computer and interact with one of the many 3D Softwares of your choice. Actively using Software utilizes the Hardware it is running on in entirely different ways.

I am modeling a car. That Car consists of Polygons that will have modifiers and Deformers applied to it, such as Mirroring, Cloning, Bending Objects, and so on.

Your computer has to go through some heavy calculations to process all this, but the key here is that these calculations are mainly done on just a single CPU Core. Because the Scene is built according to a certain hierarchy. A CPU has to work its way through this hierarchy step by step.

It can’t skip or off-load certain steps to other cores, because most of the steps depend on each other! What does this mean? It means, quite frankly, that having lots of CPU-Cores will do nothing towards speeding up your modeling and does not usually make your Viewport faster.

What Is 3D Modeling?

Long explanation short:. For Modeling and actively working in your 3D Scene, you would need to get a CPU that has the highest Clock Speed possible. It doesn’t matter if it only has a few Cores, as most of these Cores won’t be used for modeling.

Turbo-Boost (Turbo-Core)

Take a look at this page to find the highest clocking CPUs currently available. The same is also valid for working on Animations or for running a CAD Workstation. A high-Clocking CPU will almost always outperform a high-Core-count CPU in such (inter-)active workloads.

It’s now tempting to think you should get a CPU with lots of cores AND high clock speeds. After all, then we’ll have a workstation with which we can work fast AND which can render fast, right?

Unfortunately, because of power consumption and a CPU’s thermal limits, we observe a proportional trade-off between the number of CPU cores and its clock speeds.

The more Cores a CPU has the lower its frequency. This means the more Cores the CPU has, the lower its clock and vice versa. The faster the Cores are clocked, the fewer cores there usually are on the CPU. Many Cores need lots of Power and lots of Power produces lots of heat.CPUs have thermal regulations that need to be adhered to.

The same applies to higher clocked cores that will be hotter than lower clocked cores. This is quite a bummer, but the major CPU Manufacturers wouldn’t be all that major if they hadn’t found a way to improve upon this.


AMD and Intel have thought of a nice way of compensating for some of these trade-offs. Enter Turbo-Boost. Turbo-Boost is a feature that automatically overclocks Cores until thermal and power limits are reached.

Depending on the Quality of cooling, the boost duration can vary. Say, we are currently modeling and are only really using 1-2 Cores, the rest of the CPU’s cores are idle. What Turbo boost does now is overclock these 1-2 Cores as far as specified by the manufacturer and as long as the Power Consumption and Temperature stays within the predefined limit.

As soon as these limits are reached, the Turbo-Boost will clock these two cores back down. Cores can be overclocked with available temperature and power headroom. This way, to a certain degree, we can get CPUs with more Cores (and a low base-clock), that clock higher on limited cores, when needed and not all cores are being used.

There are two popular methods of Rendering Images and Animations in a 3D Software’s Render Engine: CPU Rendering and GPU Rendering.

Are you mainly rendering on the GPU or CPU?Poll Options are limited because JavaScript is disabled in your browser. As you probably guessed, CPU Rendering utilizes the Processor(s), and GPU Rendering utilizes the Graphics Card(s).

There are some differences in GPU and CPU rendering that you want to be aware of when choosing a new Computer or Workstation for 3D Rendering and Modeling:. First of all, almost every popular 3D Software comes with an inbuilt CPU Render Engine nowadays.

Frequently Asked Questions

Only recently have GPU Render Engines such as Octane, Redshift, V-RAY RT, Arnold GPU, or FurryBall become mature enough to slowly but surely overtake CPU Render Engines in popularity.

CPU Rendering

Especially because GPU Render Engines are much faster in many cases and allow for interactive preview Renderers. Changing to a GPU Render Engine is one of the top methods in achieving faster renders – given your GPU is strong enough and has a sufficient amount of VRAM. This can improve and accelerate a 3D-Artist’s Workflow tenfold as you are able to iterate more often before completing a project.

Beginners were often told to start with 3D Rendering on the CPU and later switch to (often) costly 3rd-Party GPU Render Engines when they have learned enough to properly utilize them.

This has already changed. Just look at Blender’s in-built Cycles GPU Render Engine and Cinema 4Ds newly integrated Redshift GPU Render Engine. While Cinema 4D’s Redshift isn’t free, it shows how much Maxon is willing to bet on GPU Rendering to make it it’s #1 Renderer for the future.

As explained above, you’ll have to make a decision depending on what you will use your computer for most.

The more Cores and the higher the clock speed, the better, right?

Do you use it mainly to Model, Sculpt, Texture, Light, Animate and do you spend much more time interactingwith it, than (passively) renderingon it? Then you’ll want a CPU that is clocked as high as possible! Good choices here are:. Intel i9 12900K, 16-Cores, Clocked at 3,2 GHz Base, 5,2 GHz Boost.

If you have the budget for an AMD Ryzen 9 5950X or the Intel i9 12900K, these CPUs are in the lead for active Work such as Modeling and Animation. They also sport 16 Cores which gives you good multi-core CPU rendering performance.


Texturing 3D Models and painting or sculpting, too, need a high-clocking CPU. If you consider yourself a Graphic Designer and do less Rendering, the AMD Ryzen 9 5900X is an excellent choice. Do you use this Workstation less for active work and more to Render out your Projects?

Graphics Card

Do you spend more time on Rendering than on actually sitting in front of it? You should consider going into a high core-count direction which are the best CPUs for Rendering(Or if you want a second Computer just for Rendering on).
