Top 5 Best Render Farms 2021 for CPU and GPU

Why do you need a render farm?

To render a 3D project, animations and visualizations have to be calculated to define light, reflections, or shadows. For this calculation process, time and computing performance is required besides 3D applications.  

Averagely, animation with a length of 1 second consists of 30 single frames. It means that 1800 single frames are an average number calculated for a sequence with a length of 1 minute. It can take from seconds to minutes or even hours to calculate a single frame depending on the complexity of the scene. Complex scenes with complex lighting, texture calculations require much time to complete calculating frames. For instance, a local computer that can render a single frame of a complex scene within 10 minutes, needs approximately 13 days to calculate 1800 frames. The computer runs at full capacity and it is unlikely to use during this time. 

Investing in a robust workstation or render farm needs a huge amount of money and in some cases, it is quite money-wasting when not utilizing the maximum of render farm’s power. Besides purchasing powerful hardware, you need to pay for electric bills, maintenance costs, and software licenses for each node. 

Therefore, the use of a render farm is very helpful for these cases. Some obvious benefits you would get from using a render farm are Time and Cost.

Which factors have impacts on choosing a render farm?

Easy of use

A group of UI / UX platforms supports App, 3d App Plugin, Web?

A group of pipelines and workflow is good in that the usability results can be easily integrated.

A group of upload speed/ upload projects, join with FTP, sFTP, Dropbox, Google Drive, One Driver, etc.

SaaS vs IaaS

IaaS-based render farms offer full control of remote servers and allow customers to install any software as well as customize the projects if needed (Suitable for complex pipeline and large projects)

SaaS-based render farms are more simple to use, however, end-users are not able to adjust the project when there’s a problem while rendering (Suitable for straightforward workflow and smaller projects)

Compatibility with software versions and plugins

Look at supported software, plugins, render engines (more or less, speed update)


A group of price, actual expense, implicit cost, estimate cost

Rendering speed

How many nodes are being used to render your job?

Which CPU & GPU types are offered?


A group of analyzing speed and datalog (report), price & time estimation

A group of support services: Quick response, several supporting methods, with human participants or not, etc.), truly working 24/7.

The criteria of discount, promotion, regularity, trial, etc.

The criteria of security, policy, and guidelines on the protection of privacy.

The criteria of payment methods, claim and refund.
