At 4K, with AA set to medium, the RTX 4000 was the only GPU to give what we would describe as a fluent experience, only a touch below the ideal minimum of 24 FPS. However, when AA was set to ultra high, even the RTX 4000 struggled, and the model was quite choppy in the viewport. In these types of automotive styling workflows, where visual quality is of paramount importance, you’d traditionally need to look at a multi GPU solution, although we wonder whether the Quadro RTX 6000 could deliver this on its own. In preparation for the emerging VirtualLink standard, Turing GPUs have implemented hardware support according to the “VirtualLink Advance Overview.” To learn more about VirtualLink, please see https://www.virtuallink.org. Support for large-scale, ultra-high resolution visualization using the NVIDIA ® SVS platform which includes NVIDIA ® Mosaic, NVIDIA ® Sync and NVIDIA ® Warp/Blend technologies
It was only when we set AA to ultra-high that the RTX 4000 struggled, going down from 9 FPS to 3 FPS. GPU memory possibly had an influence here as both individual processes – rendering in SolidWorks Visualize and real time viz in Autodesk VRED would have pushed GPU memory usage to well over 8GB.
GPU rendering
NVIDIA ® Quadro ® RTX™ 4000 combines the NVIDIA Turing GPU architecture with the latest memory and display technologies, to deliver the best performance and features in a single-slot PCI-e form factor. Enjoy greater fluidity with photorealistic rendering, experience faster performance with AI-enabled applications and create detailed, lifelike VR experiences more cost-effectively and across a broader range of workstation chassis configurations. Visit our booth to experience a real-time, immersive walkthrough powered by the Quadro RTX 4000. By deploying the Enscape3D plug-in and strapping on an HMD, you’ll step inside a full-scale Autodesk Revit model and make changes in real time. Support for the following audio modes: - Dolby Digital (AC3), DTS 5.1, Multi-channel (7.1) LPCM, Dolby Digital Plus (DD+), and MPEG-2/MPEG-4 AAC However, CAD applications are changing and, in the future, should be able to make much better use of the plentiful power of higher-end GPUs like the RTX A4000 and A5000. Both Autodesk with its new One Graphics System and Dassault Systèmes are currently working on new graphics engines that use more modern graphics APIs like Vulkan. This should not only improve general 3D performance but will make real-time ray tracing available directly in the viewport. So, while the RTX A4000 / A5000 might not give notable performance benefits in CAD right now, they could certainly do so in the future. This week at Autodesk University, NVIDIA is in booth C1201 demonstrating the powerful new capabilities of Quadro RTX GPUs. Designers, engineers and artists can interact in real time with their complex designs and visual effects in ray-traced photo-realistic detail and realize increased throughput with their rendering workloads for significant time and cost savings.
The Quadro RTX 4000 (8GB GDDR6), RTX 5000 (16GB GDDR6) and RTX 6000 (24GB GDDR6) are essentially replacements for the Pascal-based Quadro P4000 (8GB GDDR5), P5000 (16GB GDDR5X) and P6000 (24GB GDDR5X). There’s also a new ultra high-end model, the Quadro RTX 8000 (48GB GDDR6), which is essentially the RTX 6000 with double the memory. It’s designed specifically to overcome the challenges of using the GPU for really high-end rendering where the datasets can be incredibly complex.

While we often see models / scenes that surpass 8 GB (the capacity of the previous generation Quadro RTX 4000) scenes that are 16 GB and above are certainly less common, and more the preserve of viz specialists than most architects or product designers who use standard materials and assets. Like most CAD tools, the most popular way to view models in Solidworks is in shaded with edges mode. Using the SPECapc for SolidWorks 2021 benchmark we saw a small improvement, generation on generation with this display style. The Nvidia RTX A4000 was 1.10 times faster than the Quadro RTX 4000 and 1.44 times faster than the ‘Pascal’ Quadro P4000.
In short, the RTX 4000 should be more than adequate for any CAD or BIM application. If that application is CPU limited, then you almost certainly won’t find any GPU that will give you better performance. On the other hand, if it isn’t CPU limited, then it should be able to handle anything you throw at it. GPU rendering Improved performance of VR applications — new and enhanced technologies include Variable Rate Shading, Multi-View Rendering and VRWorks Audio. Of course, the boundaries between real-time 3D and ray tracing continue to blur. In fact, out of the list above only Lumion and Twinmotion are yet to support RTX, although it should be coming to Twinmotion soon. With 50 passes it was faster than the older GPUs and that lead got bigger with 200 passes, but we never found it delivered the same percentage performance advantage over the other GPUs as it did when denoising was off.
Technical specs
Nvidia has launched four Quadro RTX GPUs, from the mid-range to the high-end. We imagine Nvidia will launch lower-end Quadro RTX GPUs later this year but we don’t know this for sure.
In short, it looks like the RTX 4000 should be able to handle multi-tasking workflows with relative ease. V-Ray / Radeon ProRender With many firms re-evaluating office space and working from home policies, we asked Adam Jull of IMSCAD about the role that virtual workstations can play
GPU memory
In addition, it is important to note that both GPUs will be certified for a wide range of pro CAD / BIM applications, which is important for some firms. This is especially true for enterprises that buy 100s or 1,000s of workstations from large OEMs like HP, Dell and Lenovo and want assurance that the GPUs will be stable and that they will be properly supported by the software developer. The Nvidia RTX A5000 supports all the same features as the Nvidia RTX A4000 but differs in two main areas.
