Top reasons why Octane and Redshift will be the future of render engines

GPU is developing faster than ever, pushing the rendering engine and technology to catch up with its pace. Before we could only see the CPU as the main hardware to perform rendering, but right now this is the GPU’s job. With the appearance of many GPU-based render engines, and many CPU-based renderers having to support a version of GPU-based, we can see that GPU is taking over. Of course CPU is still important, but in terms of rendering, it will soon have to leave the stage for GPU. In this article, we will help you understand the top reasons why Octane and Redshift will be the future of render engines, because of their development attached tightly to that of GPU.

Top reasons why Octane and Redshift will be the future of render engines

Fast speed

We all know that GPU rendering is often faster than CPU rendering. At the beginning, CPU is used for finished rendering, while GPU is for handling the real-time rendering on screen to provide a visual interaction. As time goes by, GPUs are more and more powerful, people start to notice its potential in finished rendering. That’s how GPU-based renderers like Octane and Redshift come to the market, and slowly become two of the most used renderers for individual and 3D studios.

When you use GPU to render with Octane or Redshift, you take advantage of GPU speed. Because of its massive amount of cores and parallelism, GPU based renderers like Octane and Redshift are excellent in creating extremely fast graphics.

Octane could use a maximum of 20 GPUs, while Redshift can use up to 8 GPUs at the same time. Both are likely to speed up linearly if you put more GPUs and upgrade to a more powerful GPU, therefore it ensures you the speed when you upgrade your system.

Empowering 3D artists

When you want to work fast or render fast with CPU, you will need a render farm or large scale networked CPU solution. It’s often accessible for big studios or companies. Although one individual can still use a cloud render farm, it’s hard to access high-end hardware and configuration infrastructure like big studios.

GPU on the other hand, could solve this problem. With one GPU, it could outperform 10 CPUs. Individual 3D artists can buy one GPU and still enjoy studio-quality outputs without having to pay for a cloud render farm.

Lower cost of hardware/software installation

With the CPU rendering engine, if you want to speed up, you must have more computers, and more licenses to come with those computers. This will increase the cost of hardware you need to buy, the installation time, the cost for space, electricity efficiency, etc. It also increases the license cost.

But it’s a different story with GPU render engines like Octane or Redshift. With one computer, one CPU, you can stack many GPUs. And Octane and Redshift only need one license to run on all those GPUs. Therefore, you save money for the hardware (you only need to buy the GPU), for the license cost, for the space consumption, etc.

Potential for growth in scale

When you want to scale up your studios or a render farm of CPU rendering, it means that you need to buy more computers. Like above, the cost for space and electricity efficiency  is high. And because the CPU is developing at a slower pace than the GPU, you may not be able to see the difference in render result between the old and new one, in both quality or render time.

If you use GPU rendering engines like Octane and Redshift, it’s easier to set up the GPUs together and consumes less resources. GPU is developing fast, but the old graphics cards still have their chance to shine if you use them correctly. You can choose to upgrade to a newer card, or put more cards in your system, both work with GPU-based render engines like Octane or Redshift, and you will see the results change instantly.

Technology of the future

The growth speed of a GPU is like 1-2 years, it’s the time you may have a new graphics card. Compared to that, the growth speed of CPUs is much slower, you might have to wait 5-10 years for a big leap in CPU technology.

I personally think that’s the reason why CPU is slowly not a choice for rendering, and 3D artists, as well as studios are shifting to GPU rendering. When you have a new graphics card, it’s often 2x more powerful than the old one, the rendering is faster, the process time is faster, it’s so attractive that you can hardly ignore it.

Take an example of RTX3090 and RTX4090 from Nvidia, rendering with Octane and Redshift. When the new card RTX4090 is out, everyone talks about it, tests it, comments on it. And the results could satisfy almost everyone, with the speed being about 1.7-2 times faster than RTX3090.

Let’s see how does RTX4090 speed up your rendering.

Conclusion

Redshift and Octane will have their development going along with the development of GPU. They are slowly taking up the rendering future, where we will need more power from the GPU. CPU is still there to be the manager who makes decisions for others, but GPU will be the part responsible for graphics related.

With the power of the new GPU RTX4090 from Nvidia, now you can render Redshift and Octane at a speed faster than RTX3090 from 1.7-2 times. iRender, HPC provider with the latest and most powerful configuration in the market, offers you a variety of RTX3090 and RTX4090 server packages. From 1/2/4/6 to 8 x RTX3090s/RTX4090s, you can always find a fast and reasonable package for your project.

You just need to install your software and rendering engine, add your own license and then render by yourself on our remote machine. It’s easy as you use your second PC.

Let’s take a look at some of our tests with Octane and Redshift on RTX4090:
