Best PC for Octane users

As we known that Octane is one of the most popular render engines. Besides, Octane is a GPU render engine that uses a method of calculating final produced pictures that attempts to be photo-realistic. Octane is an unbiased rendering engine leveraging GPU technology that is very close to physical accuracy. A good PC is important for a great experience with Octane.You wonder how to choose best PC for Octane users. In today’s article, iRender will give you some suggestions to help you choose the best PC for Octane users.

1. GPU (Graphics Card) Requirements

OctaneRender supports all major platforms:

  • Windows® 7 or higher (64-bit)
  • Linux® (64-bit)
  • macOS® 10.13.6 High Sierra (NOTE: 10.14 Mojave and 10.15 Catalina do not support NVIDIA CUDA)

The most recent CUDA® 10 drivers and an NVIDIA® video card that supports computing capability 3.0 or above are recommended for OctaneRender. Additionally, it needs at least 8 GB of RAM, we think you should use 16 GB or more. The more affordable Quadro® and Tesla GPUs often have slower frame rates and render times than GPUs from the GeForce® series. OctaneRender can use many NVIDIA card types simultaneously and scales flawlessly in multi-GPU configurations. The primary advantage of using the GPU for rendering is performance. GPUs are usually much faster at rendering. You can refer to GPU recommendations for Octane:

  • GeForce RTX 3090: (10496 CUDA core, 1.695 MHz, 24 GB Vram)
  • GeForce RTX 3080: (8704 CUDA core, 1.1710 MHz, 10 GB Vram)

Last but not least, VRAM is really necessary for rendering in Octane. It helps your scenes could be loaded and processed faster. You can enable OctaneRender’s Out-Of-Core capabilities if there isn’t enough VRAM.

2. CPU (Processor) Requirements

As OctaneRender does not use the CPU for rendering, a fast multi-core CPU is not required, but it does significantly improve scene-loading speeds. With Octane, clock speed has the most influence on CPU performance. The number of cores does not appear to be important at all.

CPU will impact performance on rendering in Octane. Having lots of CPU cores doesn’t help OctaneRender, but high clock speeds do. You can choose a CPU that clocks at 3.0 GHz or higher to render with Octane. You can refer total scores from OctaneBench for the 1 to 4 Titan V cards running on the Xeon W-2125 and W-2195 processors:

Here some recommendations for CPU:

  • AMD Ryzen Threadripper Pro 3955WX @ 3.90GHz (16 cores)

3. RAM (Memory) Requirements

However, depending on your specific projects, you will need a different quantity of RAM. For OctaneRender, we recommend 32GB at minimum and more. Rendering engines like Octane are not usually run all by themselves, so you need to take account for the memory requirements of the other programs you are running at the same time. Your scene’s complexity will determine how much system memory a 3D modeling program like Cinema 4D, Maya, or 3ds Max requires.

4. Storage Requirements (HDD, SSD, or NVME)

Octane is pretty fast already, so having a super-fast SSD is necessary, it will save and load extremely large files. And one important thing is it won’t cause crashes. Generally, a standard SSD (Solid State Drive) is enough for most tasks that you would do. SSDs are much faster than any traditional hard drive at enabling your system to boot, run apps, and load files. If your budget allows, it is also a very good idea to have a second SSD that can be used to store your active projects to further decrease load and save time.


The best PC is important for a great experience with Octane. iRender hopes these tips help you can choose the best PC for render. If your budget is not enough to be able to buy a powerful PC at the moment. Let’s join iRender to boost your render now, with iRender you will have your own powerful workstation just by one mouse click.
