Best Computer For OctaneRender

OctaneRender is the world’s first and fastest unbiased, spectrally correct GPU render engine, delivering quality and speed unrivaled by any production renderer on the market. If you want to build a great OctaneRender workstation, we’d love to help you out.

In this article, we’ll be talking about the components you need to build the best workstation PC for OTOY OctaneRender.

Why choose us?

Parts like CPU cooler, Power Supply Unit, and chassis are often glossed over when putting together a system like this. Surprisingly, these parts have a massive effect on the lifespan and performance optimisation of the CPU, GPU and RAM. We only use parts that guarantee excellent cooling, airflow, and power delivery.

We’ve also got a lot of experience in putting these systems together, and our cable management is flawless. This not only means dust will be a lot less of an issue, but it will be much easier to work with when you eventually need an upgrade. This will only happen several years down the line, of course. Not to mention our cases just look fantastic.

Each Modena Computers Workstation is tailored to the personal needs of the user, but the features below would make for a great starting point for your OctaneRender workstation.

CPU – Frequency

Since Octane only uses the GPU for rendering, your CPU makes very little difference in performance. Keep in mind though, that a fast CPU in your OctaneRender workstation will increase the overall responsiveness of the software, and the system in general.

CPU – Core Count

Although the Octane itself would not even make use of 4 cores, we would recommend at least a quad-core CPU. This would allow the system to run smoothly during general use. 

You should also consider any other programs you’ll be running on your OctaneRender workstation, as other software will have different hardware requirements.


Your graphics card will be the most important factor in determining the performance of Octane. Octane can also leverage multiple graphics cards and performance scales linearly with the amount of graphics power you have installed.

It’s also important to factor in the PCI-Express speed and bandwidth of the motherboard and CPU you will be using, especially when configuring a multi-GPU rendering workstation for Octane.


OTOY officially lists 8GB as the minimum amount of RAM for Octane, but they recommend 16GB or more. We would recommend going for 32GB if your budget allows since this will help the system with other tasks as well.


Storage technology has come a long way over the past decade. Solid State Drives are known to be much faster than mechanical hard drives, but they’re also seen as pretty expensive.

It was pretty common to install the OS on a 120GB SSD, and everything else on a 1TB HDD, so that you could at least start up your PC super quickly.   

Recently it’s become more viable to just use a larger SSD, from around 500GB to 1TB, and this is exactly our approach with our PCs. Having everything stored on SSDs means you’ll be able to save and load programs, and also transfer data, at incredible speeds. The SSDs we use are M.2 form factor and use the NVMe protocol, which means they take up no additional space in your case, and are even faster than standard 2.5” SATA drives.

These drives save a lot of time, and that means the PC will pay itself off a lot faster. You also still have the option of adding in some HDDs if you need to.


As we said before, each Modena Computers Vulcan Workstation is custom built to the workflow and budget requirements of its user. It’s important to consider other programs you may want to use with this workstation.

During our consultation process, you can let us know exactly which programs you want to use with your machine, and we’ll be happy to help you understand what you need. 

Keep in mind that opting for higher performance right out of the gate offers much greater value than getting exactly what you need right now. A higher performance PC won’t need downtime to upgrade any time soon, and will also allow you to complete more work in less time. It could pay itself off a lot sooner than a more affordable option.
