Hardware Recommendations for Redshift with iRender

One of the top rendering engines on the market is Redshift from Maxon. Redshift stands out from the competition due to its quickness, customizability, and ability to produce stunning outputs. Redshift gives artists the power to build environments that completely match their ideas for everything from blockbuster films to AAA video games. But surely there must be a cost to all that power and a requirement for performance.

We’ve created a list of things about our hardware recommendations for Redshift that gonna help build your powerful workstation and why iRender might become an effective solution for Redshift to speed up the rendering process and bring incredible rendering results.

Processor (CPU)

As we all know, Redshift is a GPU-accelerate render engine, as well as most other GPU-based engines, the CPU does not play a direct role in the process of rendering scenes. It does slightly affect how long it takes to load a scene, but in the overall scheme of things, that is relatively negligible. However, if you are also using the same system for modeling or animation – in a program like Cinema4D, Maya, or 3ds Max – then you will want a CPU with a high clock speed in order to ensure smooth performance in those applications.

On the other hand, in the newer version of Redshift, Maxon has allowed users to render with Redshift on CPU. When users choose Redshift CPU as a default rendering setting, it means that Redshift no longer utilizes the power of GPUs. In this case, having a higher core count of CPUs will be an essential feature. 

Aside from raw performance, it is also important to consider the number of PCI-Express lanes a CPU supports. This will limit the number of video cards that may be used, which has a significant effect because video cards are the main factor in Redshift’s rendering performance.

We have come up with this selection of CPUs that not only can serve as an unreplaceable addition when you use GPU-accelerated Redshift rendering but also can be a strong option for Redshift CPU rendering.

  • AMD Ryzen 7 7700X 8 Core – This is one of the highest clock speed CPUs available, and does very well with both Redshift and modeling / animation applications. It has enough PCI-Express lanes to support dual video cards, along with other standard hardware devices (NVMe drives, etc).
  • AMD Threadripper PRO 3955WX 16 CoreAMD’s Threadripper PRO processors have far more PCI-Express lanes than more consumer-oriented models. Combined with the right motherboard, this CPU can allow up to four video cards in a single tower workstation.

At iRender, all our current servers include both CPU and GPU, suitable for both CPU & GPU-based Redshift Rendering. We provide machines using high core count CPU AMD Ryzen Threadripper Pro 3955WX 16 cores and 32 threads. Therefore, if you don’t have enough budget or waste that much money to built-up a workstation with expensive CPUs. iRender must be a highly considerable option for Redshift users.

Video Card (GPU)

The GPU is the most important component when it comes to working with Redshift. All the rendering is done on it. So the faster the better, and you can also use multiple GPUs to further speed up rendering. There’re two aspects of video cards that impact render capabilities: the raw speed of the GPU itself and the amount of memory on the card. So below are our hardware recommendations for redshift about GPU.

Redshift tries to store the scene data, such as the geometry and textures on your VRAM while it renders the scene, so if you don’t have enough VRAM, you wouldn’t be able to render complex scenes quite as fast—you might still be saved by a feature called “out of core rendering”. But that comes with a reduction in speed, so it is best to get video cards with enough RAM onboard if at all possible. 

GeForce cards tend to have good raw performance, with decent amounts of video memory, while Quadro cards come with larger amounts of VRAM but also cost more for the same level of raw performance. Here are the three best GPUs highly recommended.

  • GeForce RTX 3080 Ti 12GB – A great choice if you want just one or two video cards and don’t work with overly complex scenes. 
  • GeForce RTX 3090 24GB – Our go-to recommendation for most GPU rendering customers, the RTX 3090 provides the best performance in Redshift while also having a tremendous 24GB of memory.
  • NVIDIA RTX A5000 24GB –  The RTX A5000 is the top-end card that can be installed in a set of four in large tower chassis and still be within the limits of a 1600W power supply. 

 iRender take power from NVIDIA RTX 3090, our servers vary from GPU single card to 2/4/6/8 GPU cards, based on the need and budget, customers can choose which server they would like to use on Redshift. 

NVIDIA RTX 3090 is already a significant choice for Redshift Renderer. iRender has just released a completely new server – GPU server 4S which is equipped with the newest NVIDIA RTX 4090, promised to be much faster than RTX 3090. Let’s wait for more of our RTX 4090 servers in the near future!

Ram (Memory)

VRAM is very important for Redshift, but if you encounter a situation where you don’t have enough VRAM for Redshift to store all the data it needs to render a given scene, Redshift can use its out-of-core rendering technology to shift that data to your RAM instead. However out-of-core rendering doesn’t support all data types that might get stored in the GPU VRAM, namely sprite node textures and volume grids. 

So here are our hardware recommendations for Redshift about VRAM. While the exact amount of RAM you need is going to depend on your particular projects, we generally recommend 24-48GB.

Storage (Hard drives)

With the falling costs associated with SSDs, we almost always recommend using an SSD for the primary drive that will host your OS and the installation of Redshift and other software. The high speed of SSDs allows your system to boot, launch applications, and load files many times faster than any traditional hard drive. 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 times.
