The Best CPU Render Farm For CPU Rendering in 2023

What is CPU Rendering

The CPU (Central Processing Unit) rendering engine acts as the control center for the entire computer, with the core task of converting data input into information output. As the first available renderer in history, the CPU renderer is widely used and is essentially the industry standard for rendering. Let's look at some of the benefits that CPU render farm brings to the table.

1. More RAM

GPU rendering seems to be faster when rendering low complexity images, but once you add complexity to things it starts to fall apart. Now 128 GB of RAM may be enough for production rendering. But let's consider 100+ million input polygons, subdivision of input geometry into subdivision surfaces and displacements, 1TB+ textures, and render time programs. These programs can increase scene complexity exponentially as they extend the new geometry program to generate it by running subroutines during rendering, massive (smooth) curve renders for hair and grass, large particle renders for FX, clouds and explosions for OpenVDB ...... (Chan Dra) At this point, there is simply no chance of fitting all this in GPU memory, so for scenes with complex geometric, physical simulations, CPU rendering is clearly more advantageous.

2. Able to Handle Complex Tasks

For complex tasks, the CPU can outperform the GPU, which has been optimized for processing large amounts of data by performing the same operations quickly and repeatedly. This means that you can take advantage of the GPU's optimal processing power if all cores perform exactly the same operation at the same time. When processing different tasks that are not similar, it is difficult to keep everything in sync, whereas the CPU can perform without problems. The architecture of the CPU is therefore ideally suited to handling 3D scenes.

3. Stable Performance

The driver may be the problem with GPU-based rendering. If your computer crashes frequently, your graphics card is the cause of the driver problem. Unfortunately, the graphics card is one of the most unstable and highly complex parts of a computer. If a driver update comes out of nowhere, then a problem can be expected later. There is no need to worry about such issues with the CPU-based solution, which is a stable and well established renderer that rarely has problems.

4. Quality

For many 3D artists, the quality of the image is more important than the speed at which the media is processed. As it is an integrated solution, CPU Renderer offers greatly improved image quality. If you are someone who prefers accurate quality over time efficiency, then CPU Render is perfect for you.

CPU Rendering Engine

There are world-renowned CPU rendering engines that are widely used by 3D artists. The following two brands can be considered as the best rendering engines for CPU rendering.

1. Corona Renderer

Corona Renderer is a biased and unbiased renderer capable of outputting realistic visual effects. Corona Renderer is now only available for Autodesk 3ds Max , MAXON Cinema 4D.

The development of Corona Renderer started in 2009 as a student project at the Czech Technical University in Prague, Ondřej Karlík. in August 2017 the company became part of the Chaos Group and was allowed to expand and grow further. Although still young, Corona Renderer has become a production-ready renderer capable of creating high-quality results. Corona has a built-in noise reducer that removes noise from images using data from the rendering channels and 3D scenes. This means you don't have to wait for the entire rendering calculation to be completed.

2. Arnold

Arnold is an advanced ray tracing renderer built to meet the needs of long-form animation and visual effects. Arnold has a quality that makes images look as close to realistic as possible. This is partly because Arnold is an unbiased rendering engine. This means it will mimic the real world as closely as possible, without taking shortcuts. It also has to do with the algorithms it uses behind the scenes to compute images.

Arnold was acquired by Autodesk in 2016 as a CPU-based and was recently introduced in early 2019 to use GPU rendering. Arnold is now compatible with Autodesk 3Ds Max, Maya, Maxon Cinema 4D, SideFX Houdini and Katana.

Best CPU Render Farm

In addition to the advantages offered by the CPU rendering solution described above, there are obvious disadvantages of CPU rendering. Specifically, rendering a project via CPU usually takes a significant amount of time, even hours or days. If you need to speed up your rendering time, increasing the number of render nodes that render multiple frames simultaneously may be an ideal solution. However, building a powerful workstation or your own render farm with a large number of render nodes will cost you thousands of dollars. In addition to investing in a powerful machine, you will need to pay for electricity, maintenance costs, etc. to operate these render nodes.

It seems that this solution may be more time consuming and costly. Is there another way to reduce rendering time at a reasonable price? The answer is yes. Fox Renderfarm was created to solve your problem when it leverages the power of hundreds of CPU render nodes to do your job with ease.

Fox Renderfarm has a team of employees experienced in the field of computer graphics. With professional services and industry-leading innovation, they provide cloud rendering services to a variety of entertainment studios and animation studios from over 50 countries and territories. Fox Renderfarm is known as a world pioneer in cloud rendering, with examples such as Mr. Hublot and Three Robots, etc..

It can be said that Fox Renderfarm ranks among the best CPU-based render farms. Fox Renderfarm has a user-friendly UI/UX that makes it easy for customers to use. As a SaaS-based render farm, you first need to prepare your project on your local computer and then upload or download files through Raysync, a free application developed by Fox Renderfarm, which can be considered as a high-speed transfer solution. Users can upload any type of file format of any size through Raysync.

Fox Renderfarm supports the best CPU rendering, especially 3Ds Max, Maya or C4D. Some of the CPU rendering engines that can be used in this render farm are Corona, Renderman or Clarisse. Most importantly, fast support is a plus when using Fox Renderfarm services. Fox Renderfarm offers its customers 24/7 support through live chat on their website and is always ready to answer all your questions and queries. New users who sign up for Fox Renderfarm can receive a free $25 rendering coupon.

Conclusion

CPU rendering has some advantages that may pale in comparison to GPU rendering, such as image quality, stable performance, and large memory. However, rendering on the CPU is much slower than the GPU. It can even take days or weeks to render an entire project on a CPU. Therefore, considering a CPU render farm is an effective solution to reduce rendering time from hours to minutes. In the cloud rendering service market, Fox Renderfarm, as a TPN-accredited cloud rendering farm, is the most trustworthy CPU render farm in terms of price and service.
