How fast is a 2x RTX 4090 workstation for Blender rendering?

NVIDIA GeForce RTX 4090 deserves the title of the new Rendering Champion when its GPU rendering is often nearly twice as fast as the previous generation RTX 3090 or RTX 3090 Ti. Obviously, a single RTX 4090 is already very fast on its own for Blender rendering. However, do you know how much faster a 2x RTX 4090 workstation for Blender would be? Let’s find the answer in this article!

Powered by the new ultra-efficient NVIDIA Ada Lovelace and 3rd generation RTX architecture, the GeForce RTX 4090 is beyond fast, giving 3D artists a quantum leap in performance. RTX 4090 beats the RTX 3090 and RTX 3090 Ti as regards the CUDA cores, RT cores, Tensor cores, and clock speed as shown in the image below. 

We see an impressive  52% to 56% increase in CUDA core counts of NVIDIA’s new top-tier RTX 4090. While the previous-generation top-tier RTX 3090 Ti has only 10,752 CUDA cores and RTX 3090 has just 10,496 ones,  RTX 4090 features 16,384 CUDA cores. That’s a significant jump. It also comes with a newer and higher generation of RT cores and Tensor cores. All these increases help to deliver faster ray tracing and better DLSS. There is also a 35% to 48% increase in boost clock compared to RTX 3090 Ti and RTX 3090, helping in delivering the significant performance gains NVIDIA promised.

We will have to see how these increases translate to real-world performance. However, there is no doubt that RTX 4090 will be significantly faster than any other NVIDIA graphics card currently on the market.

NVIDIA showed off an absolutely fantastic graph for professional workloads.

As we can see from the graph, the improvements here are pretty substantial. In Blender, we are looking at a 60-70% uplift in render speeds. RTX 4090 was 70% faster than RTX 3080Ti, 55% faster than RTX 3090 Ti, and nearly 22% than RTX 4080. 

CG Director tested RTX 4090 performance in Blender (Optix) and below are the benchmark results.

RTX 4090’s score is twice as high as the score of RTX 3090 Ti and RTX 3090. It’s so clear that NVIDIA has been continuing its tradition of effectively doubling the GPU performance with each subsequent release (2080 Ti to 3090 to 4090). If you mainly use Blender and need all the speed you can get for Optix rendering from a single graphics card, the RTX 4090, at the moment, has absolutely no peer.

Puget Systems also joined the review. After testing a variety of GPUs on the market in Blender 3.3 (the latest version, in GPU rendering mode), they included that RTX 4090 is the Champion for Blender rendering. It once again scores nearly double the RTX 3090 Ti or RTX 3090.

There are also 48,807 openly accessible benchmarks provided by the Blender community that show the same result.

Taken as a whole, RTX 4090 is a new beast when it comes to Blender GPU rendering. In most cases, it is nearly double the best 30-series graphics cards.

When a single RTX 4090 is twice as fast as the RTX 3090 Ti and RTX 3090, do you think that a 2x RTX 4090 workstation will be four times as fast as the 30-series GPUs? Well, it can be even faster or slower depending on each project. 

Let’s take a look at iRender’s latest GPU Server 4S with dual RTX 4090 to find the answer.

Being built with 2 GPUs RTX 4090, a strong AMD Ryzen Threadripper Pro 3955WX processor, 256GB RAM capacity, and 2T NVMe SSD storage, this is an ideal machine for Blender GPU rendering. It has been the most sought-after machine since it was launched on the iRender’s system. 

Let’s see how a 2x RTX 4090 workstation for Blender is going to prove to be an absolute screamer:
