About this deal

Hardware support for VirtualLink — new open industry standard meets the power, display and bandwidth demands of next-generation VR headsets through a single USB-C connector 1. Turing SM Architecture (streaming multi-processor design that delivers greater processing efficiency) It even managed to beat the AMD Radeon Pro WX 8200 in the DX 12-based Cyan Room, a test that AMD usually does well in because AMD’s Vega architecture is designed to perform well with low-level APIs like DirectX 12 and Vulkan. 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.

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. GPU rendering is nothing new; we’ve been writing about it in this magazine for ten years now. But 2019 could be the year that it really comes of age. While most of the renderers built into CAD applications still rely on the CPU, there are a growing number of impressive GPU renderers. These include SolidWorks Visualize, V-Ray NEXT GPU, Siemens Lightworks, Lumiscaphe, Catia Live Rendering or any renderer that uses Nvidia Iray. Even Luxion KeyShot, a die hard CPU renderer and one that is particuarly popular with product designers, was recently demonstrated running on Nvidia GPUs. Nvidia Quadro RTX 4000 – SolidWorks Visualize

While most CAD applications won’t benefit from any GPU more powerful that the Nvidia Quadro P1000 or P2200, Solidworks 2021 is an exception. By using OpenGL 4.5, a more modern version of the popular graphics API, more algorithms can be pushed onto the GPU so there is a benefit to higher performance GPUs. For our tests we focused predominantly on SolidWorks Visualize. The name of this GPU-accelerated physically-based renderer is a bit misleading as it works with many more applications than the CAD application of the same name. It can import Creo, Solid Edge, Catia and Inventor, as well as several neutral formats. Nvidia has published some preliminary benchmark figures, comparing the results from Quadro RTX 4000 (with RTX acceleration in SolidWorks Visualize 2020) and a Quadro M4000 (in SolidWorks Vizualize 2019). What it hasn’t given is a direct comparison between the Quadro RTX 4000 in Visualize 2019 and Visualize 2020. 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

Turing Tensor Cores for 57 teraflops of deep learning performance — accelerate neural network training and inference, which are critical to powering AI-enhanced rendering, products and services. Enscape provided two real world datasets for our tests – a large residential building and a colossal commercial development. The GPU memory requirements for these models are quite substantial. The residential building uses 2.8GB @ FHD and 4.5GB @ 4K, while the commercial development uses 5.5GB @ FHD and 6.9GB @ 4K. This was fine for our tests, as all five GPUs feature 8GB or more. Quadro T2000, Quadro T1000, Quadro P5200, Quadro P5000, Quadro P4200, Quadro P3200, Quadro P4000, Quadro P3000, Quadro P2000, Quadro P1000, Quadro P600, Quadro P520, Quadro P500, Quadro M2200, Quadro M1200, Quadro M620, Quadro M520, Quadro M5500, Quadro M5000M, Quadro M4000M, Quadro M3000M, Quadro M2000M, Quadro M1000M, Quadro M600M, Quadro M500M, Quadro K2200M, Quadro K620M higher performance for both deep learning inference and High-Performance Computing (HPC) applications. NVIDIA ® CUDA ® Parallel Computing PlatformIn 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 HDR support over DisplayPort 1.4 (SMPTE 2084/2086, BT. 2020) (4K @ 60Hz 10b/12b HEVC Decode, 4K @ 60Hz 10b HEVC Encode)

Pro driver feature dramatically increases 3D performance by dynamically reducing viewport resolutionWhile GPU rendering is a major play for the Nvidia RTX A4000 and Nvidia RTX A5000, real-time 3D using OpenGL, DirectX and (in the future) Vulkan continues to be a very important part of architectural visualisation, with applications including TwinMotion, Lumion, Enscape, Unreal Engine, LumenRT and others. As we wait for AMD to deliver a Pro version of its ‘Big Navi’ Radeon RX 6000 series GPUs with hardware ray tracing, Nvidia’s biggest competitor in pro graphics is currently itself. 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.

Assimilate Scratch]: The application may crash due to a kernel exception in the NVIDIA OpenGL driver. To find out, we set a render going in SolidWorks Visualize, then loaded up the colossal MaunaKea Spectroscopic Explorer telescope assembly in SolidWorks 2019 using the new OpenGL 4.5 beta graphics engine. When panning, zooming and rotating, everything felt really responsive, which wasn’t always the case with the Quadro P4000. Viewport performance did drop – from 41 FPS to 25 FPS but this didn’t impact our experience in any way. We upped the ante with Autodesk VRED, which demands even more from the GPU, but again everything felt fine. With AA set to ‘off’ it dropped from 35 FPS to 22 FPS and with medium AA from 21 FPS down to 14 FPS. To get an idea of what this might be, we first replicated Nvidia’s render test on our own machine, obtained very similar render time, then adjusted the figures slightly.For Nvidia GPUs we used the 416.78 driver, so it could be compared directly to existing results. For the AMD Radeon Pro WX 8200 we used the 18.Q4 driver.
