Is Multiple GPUs Worth It For Rendering?

If you have looked at the GPU reviews and benchmark tests available on the internet, you would have realized that the new GPUs from Nvidia actually scales really well, the performance improvement is almost linear when more GPUs are added.

As GPU prices are finally coming back down, it is about time to increase your productivity with more GPUs. H3 Platform proudly introduces Falcon GPU Expansion Solution for those who wish to add multiple GPUs to your system whether for graphical workloads or for AI and HPC applications.

Here is a rendering benchmark test done by Mediaman Studio Services using multiple GeForce RTX 3090.

The first comparison is between GPU direct-attachment and externality using one RTX3090 GPU to render The Junk Shop scene. The result for direct-attached RTX3090 was 42 seconds while the results for externally attached RTX3090 through Falcon GPU system was also 42 seconds. It suggests that the performance drop due to externality of Falcon 4205 GPU expansion system is insignificant.

The second comparison is the rendering performance using different number of RTX3090. The BMW scene rendering results were 20 seconds, 12 seconds, and 6 seconds for one RTX3090, two RTX3090 and four RTX3090 respectively. The Classroom scene rendering results were 65 seconds, 29 seconds, and 17 seconds for one RTX3090, two RTX3090, and four RTX3090 respectively. The results suggest almost linear scalability in rendering performance when the number of GPU increases.

For those who has heavy graphical workloads to deal with, it is totally worth it to invest in GPUs, and Falcon GPU solution is able to save you lots of time and effort in terms of hardware configuration.

There are different models of Falcon GPU Expansion Chassis for your choice. The 4-GPU model is suitable for smaller scale systems such as workstations, whereas the 8-GPU model is suitable for larger scale systems. Also, there are different series designed for different GPUs. The Falcon 42 series serves any graphics cards like RTX 3090 and RTX A6000 that are over 300W in TDP. On the other hand, if the GPU model you have is less than 300W in TPD, the Falcon 40 series would be a great choice for you. Last but not least, the Falcon 41 series is designed to accommodate single-width GPUs like Nvidia RTX A4000 and A10.

The Falcon GPU Expansion Chassis allows multiple GPU to be connected externally to your current system through PCIe 4.0 interface, without performance dropping, while coming with sufficient power and cooling for multiple GPUs to work at peak performance. The set-up of this disaggregated GPU solution is also quite simple. By placing a PCIe x16 HBA card in the existing machine, users are able to connect the GPU chassis to with external PCIe cables. As a result, users wouldn’t have to worry about anything on the existing system, GPUs can be plug and play just like any other external devices. In addition, the solution comes with a web-based management software for users easily monitor the status of the GPUs and manage them all from the graphical user interface.
