In my view, pricing is one of the important aspects of rendering in a farm (others being the ability to actually deliver the project, the level of support and how easy it is to use them). So let’s see how render farm pricing works.
What is a GHz-hour? What about a core-hour?
You have probably seen some online render farms that are showing a price per GHz-hour or per core-hour for their rendering time. It’s a system that can be confusing for a first-time user. They usually do this because they have servers from several generations of hardware. And with the hardware performance being uneven, they are trying to find a common denominator to build a pricing strategy. The result: these two units — GHz and core-hour — which unfortunately require some effort and attention from users to get the price right.
