How do render farms charge you for rendering? Here is how it really works.

In the world of computer-generated imagery (CGI), render farms have become a crucial tool for artists and studios to create high-quality, complex 3D scenes. These render farms offer a significant advantage by providing the processing power required to render these scenes in a fraction of the time it would take on a single computer. However, understanding the pricing structure of these render farms can be a challenge for many artists and studios.


Render farms often use credits as a form of payment for their services instead of real currency. There are several reasons why this is done:

1.Simplified Payment System:Render farms often have customers from all over the world, and using a single currency can be a logistical nightmare. Using credits allows customers to pay for services in a standardized currency that is accepted universally across the platform.

2.Flexible Pricing: Credits give render farms the flexibility to offer various pricing options and discounts to customers. It is easier to manage and adjust credit-based pricing models as compared to traditional currency-based pricing models.

3.Convenience: Credits offer a convenient way for customers to manage their expenses and keep track of their spending on the platform. They can be easily purchased and used for multiple transactions without having to go through the hassle of converting currencies every time.

Calculation of the costs

GPU Render Farm Costs

Render farms typically charge for their services based on the amount of processing power used per hour. For GPU rendering, most render farms use the OctaneBench points per hour (OBPPH) system. The OctaneBench is a benchmarking tool that measures the performance of a graphics card while rendering a specific scene. The tool generates a score based on the graphics card's speed, and this score is then used to calculate the price of rendering a scene on a render farm.

For example, if the price is $0.005 per OctaneBench point per hour, a GPU card with a score of 1000 points will cost $5 per hour.

You can use this information to make an estimate for your own renders. You can download Octanebench or look at this list

Most render farm have price calculator on the website where you can fill in your details and get a good estimate. Here some example websites:

CPU Render Farm Costs

For CPU rendering render farms may use the GHzh or Cinebench systems to calculate their prices.

Cinebench system is considered the more accurate system because it uses a benchmark tool that artists and studios can compare to their own workstation. This tool is build by Maxon and works the same as Octane bench. This makes it very easy to compare your own workstation and get a good estimate.

If the price is $0.0005 per Cinebench point per hour, a workstation with a score of 10000 points will cost $5.

GHzh - Let's imagine we have a computer that has only one CPU and one core, which was working at precisely 1GHz in the past. If you were to render your scene on that computer for an hour, the used "compute time" would be known as 1 GHz-hour. Although, nowadays, computers have many more cores and operate at much higher speeds than 1GHz, the idea of a GHz-hour is still applicable. We calculate the overall cost of your project by multiplying the number of cores by their clock speeds, the render time on that CPU, and the power rate you specify when submitting the job (cost per GHz-hour).

In conclusion, understanding the pricing structure of render farms is crucial for artists and studios when budgeting and planning their projects. Render farms typically charge based on the amount of processing power used per hour, with different systems used for GPU and CPU rendering.
