A render farm created with eight Raspberry Pis!!

Really stoked about this! Carl C. has written an article about his Raspberry Pi Render farm. The article is up on Crowdrender, and is a short read, about 3 mins. If you're interested in hardware that uses arm based chips on Linux, highly recommend you check it out!

About Author


I'm a software engineer, I've worked on numerous technologies over the past 10 years. I started out working on full motion flight simulators and then worked with embedded systems. I now work on building an add-on to support rendering using multiple computers over internet/local networks. I started using blender in 2009 and have done small projects with it since then, however, crowd render, our network rendering add-on is by far the biggest adventure with Blender to date.

    That sounds fun like a fun project!
    Beyond its undeniable instructive nature, how does it compare to price-equivalent solutions from a performance perspective?

    • Not sure about that, but its a good question. Carl wrote in the article the total cost for all the parts. So you'll have the numbers for the system to compare. Performance wise, well he's also quoted the render times for some popular benchmarks so you could take that data and then compare against Blender's open data project, should give you a good idea of whether this is worth the while from a performance vs cost perspective.

        Given the render times on the page, the 8-Pi setup is slightly outperformed by an AMD Ryzen 5 running exclusively on the CPU. Looks like it could be worthwhile if the costs came down on the Pis, but maybe better to use a full system with a discrete GPU if "render power per dollar" is the primary concern.

        • Thanks man! Good to know that. One thing we've not yet looked at is power consumption too. Would be good to know the power demands of the whole Pi setup vs the PC.

          We've got a Ryzen based system here, 3950X, pulls about 90W idle and 200+ during rendering on the CPU. Hybrid rendering with a GPU is a bit more than that, ok, a lot more than that, 300-400W xD

            Thank you, to both of you.
            I had seen the data, I just could not make sense of it.
