Cinema 4D and V-Ray GPU Performance Scaling With iRender Cloud Rendering

Chaos Group has two different versions of their rendering engine: (1) V-Ray Next CPU and (2) V-Ray Next GPU (previously V-Ray Adv and V-Ray RT, respectively). The first is a CPU-based rendering engine that benefits greatly from having a high number of CPU cores. In fact, it scales almost perfectly with more cores which makes a high core count CPU – and even configurations with multiple physical CPUs – excellent for performance. For that version, we strongly recommend a dual CPU configuration.

On the other hand, V-Ray Next GPU (V-Ray RT) uses GPUs – as the name indicates – to perform the rendering calculations. In October 2020, V-Ray 5 for Cinema 4D was released. In the article today, we will focus on the advancement of the new technology century, V-ray Next GPU to find out the best solution bringing quality and high-speed to your rendering with Cinema4D and V-Ray.

Starting in V-Ray 3.6 the CPU can be used alongside the GPUs to further boost rendering speed. Chaos Group calls this Hybrid Rendering, so if you are using 3.6 or higher the CPU should still be a factor that affects your render process.

At first glance, this makes sense because the CPU does help speed up some parts of the rendering process, such as scene preparation (load files) but not many 3D artists know this fact. Technically, there are two factors that you should consider when choosing CPU:

• You should go for a max-core-clock CPU. For example, the AMD Ryzen Threadripper Pro 3955WX that clocks at 3.9 GHz (4.2 Ghz Turbo) or the AMD Ryzen Threadripper Pro 5975WX that clocks at 3.6 Ghz (4,5 Ghz Turbo).
• Besides, another important factor is the PCIe-Lanes because GPUs are connected to the CPU via PCIe-Lanes on the motherboard. Different CPUs support a different number of PCIe-Lanes. Top-tier GPUs usually need 16x PCIe 3.0 Lanes to run at full performance without bandwidth throttling.

In the table above, we found that both of them offer 128 PCle lanes and meet the requirements of Top-tier GPUs for Vray and Cinema4D, with a slight advantage of 5975WX.

V-Ray does have the option to utilize OpenCL which means that you can use AMD cards for rendering. However, we typically recommend using NVIDIA-based cards due to two reasons.

• First, we have found them to be more reliable overall – especially for consistently heavy tasks like rendering.
• Second, OpenGL mode only exists in some versions for use with AMD graphics cards, but the main focus is on the CUDA mode for NVIDIA cards. For example, the new Hybrid Rendering mode (CPU + GPUs) in V-Ray 3.6 only works with CUDA mode, which requires NVIDIA graphics cards. Users using AMD will not get the embree acceleration because that’s an NVIDIA bonus

When the engine is set to V-Ray GPU with RTX enabled, V-Ray GPU uses the RT Cores in NVIDIA RTX GPUs. Render speed is primarily determined by the number of CUDA cores (the more the better) and the GPU’s clock speed.

With up to 18X faster rendering than CPU-based solutions and enhanced performance with NVIDIA NVLink™, V-Ray Next GPU with RTX support provides incredible performance improvements for your rendering workloads. 

Here is the chart showing the performance of some NVIDIA GPUs:

One of the tests from Wccftech.com points out the speed of RTX4090 for V-Ray Next. Chaos has their own benchmark utility and the result shows that one RTX4090 could be nearly 2.3 times faster than one RTX3090, and nearly 2.2 times faster than RTX3090 Ti. RTX 4090 is still a very stable graphics card with good performance.

The GPU-accelerated version of V-Ray is able to utilize multiple GPUs and does so very effectively. It will not be a perfect “4 GPUs is 4x faster”, but you can expect significant performance improvements with every card you add. However, since V-Ray is using the cards for compute purposes they do not need to be in SLI mode.

As Puget Systems tests with a variety of graphics cards, V-Ray 5 scales very well with RTX 4090 and adding multiple GPU. RTX4090 without doubt is the fastest with one card now can score 5738, doubles the score of RTX3090 and nearly doubles that of RTX3090 Ti.

When you combine two RTX 4090s, they also outperform two RTX 3090s with slightly 2 times faster in speed. Moreover, two RTX 4090s score 1.9 times higher than one RTX 4090, so it nearly perfectly linear when you scale more GPU in your system.

That’s the reason we recommend using at least 2 GPUs for V-ray and Cinema4D to get the best performance.

iRender is a Professional GPU-Acceleration Cloud Rendering Service provider in PC optimization for rendering tasks, CGI, VFX with over 50.000 customers and being appreciated in many global rankings (e.g. CGDirector, Lumion Official, Radarrender, InspirationTuts CAD, All3DP, VFXRendering). Based on the above analysis, we provide a specific server for Vray: Processor AMD Ryzen Threadripper Pro 3955WX or 5975WX with a high clock speed of 3.9 GHz– 4.2GHz or 3.6GHz to 4.5GHz. Combining with 2TB SSD to load your scene fast, these servers come with 1/2/4x  NVIDIA RTX 4090 and a VRAM capacity up to 24GB.

Why you should choose iRender for Multi-GPU Cinema 4D and V-Ray Next?

A multi-GPU workstation, especially the RTX 40 Series, draws more power under load than its predecessors. They do require a larger chassis, a strong power supply, and plenty of airflow from the case fans.

Your local computers can overheat or shut down during the rendering process. However, this will never happen if you choose iRender render farm as we officially upgrade the Data Center to Tier III international standard. (a globally recognized standard for data center reliability and overall performance)

Investing $3000 for a graphics card, >10.000 USD for using Multi-GPU, not to mention the costs of compatible factors  to build a computer, is also very expensive. This is such a big investment for single individuals or freelancers or even small studios. 

At iRender, you can start at 8.2 USD to use the beast RTX 4090. You can rest assured that our pricing schemes are the cheapest you have ever found, with rates three times lower than that of other solutions. Besides our hard-to-beat prices, we also offer generous volume discounts, which provide you with credit bonuses depending on how much you top up. Moreover, you can always save up to 10% with our rental plan. 

Normally, most render farms use Farm Manager – the supplier’s farm management tool. However, rendering can also be canceled just due to a lack of material warning. This problem happens because the automatic system could not understand the settings of V-ray files.

Unlike other render farms , iRender provides you a powerful machine with up-to-date NVIDIA GPUs, then users will remotely connect and take full control of it. Using our remote PC  is no different from your local PC. You can install any plugin you want.

Users can access our web-based online platform and use multiple nodes to render at the same time. Hence, with us, it does not matter where you are present – as long as you are connected to the internet, you can access and enjoy the 24/7 rendering services that we provide, and if you meet any issue, our real human support team is always ready to support you from 6:00 to 24:00 (GMT +7).

iRender is one of a few render farms providing a unique transfer file tool, without having to access a third party for transferring data. With this tool called iRender GPU, you can upload your data even when the remote server is turned off and it will automatically sync to the remote servers and vice versa.
