HDR support over DisplayPort 1.4 (SMPTE 2084/2086, BT. 2020) (4K @ 60Hz 10b/12b HEVC Decode, 4K @ 60Hz 10b HEVC Encode) 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.

Overall, Nvidia has done an excellent job with its next generation pro GPU. Even without the future promise of RTX acceleration, it’s hugely impressive for the price and firmly cements the role of the GPU as a multi-functional processor and not just a graphics card for interactive 3D. It looks like it will still take Nvidia some time to truly deliver on its real time ray tracing vision, but it’s certainly on the right path.

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 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.

Nvidia’s new Ampere-based pro GPUs, the Nvidia RTX A4000 and RTX A5000, offer a big step up from the Turing-based Quadro RTX family. With more memory and significantly enhanced processing, they promise to make light work of demanding real-time ray tracing, GPU rendering and VR workflows. Even so, the application is still CPU limited to some extent, so the performance benefit the new cards give you isn’t as big as you’d get from a dedicated real-time viz tool. 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.

Two, it supports Nvidia RTX vWS (virtual workstation software) so it can deliver multiple high-performance virtual workstation instances that enable remote users to share resources. In the Lenovo ThinkStation P620, for example, you could get a very high density of CAD/BIM users who only need high-end RTX performance from time to time. The new 12 GB ‘consumer’ GeForce RTX 3080 Ti, for example, might have half the memory of the Nvidia RTX A5000, but offers more performance on paper for half the price. Nvidia even has a GeForce Studio driver for applications including Enscape, Unreal Engine and V-Ray. Its lead in SolidWorks Visualize was quite outstanding, delivering rendering output nearly twice as a fast as the Quadro P5000. And things only look set to get faster. With our estimated additional 35% performance boost when its RT cores are put to work in SolidWorks Visualize 2020, this represent more than a significant boost to rendering workflows. The results were impressive. In the CUDA test, the Nvidia RTX A4000 was 1.62 times faster than the previous generation Nvidia Quadro RTX 4000 and in the RTX test 1.70 times faster. The lead over the Pascal-based Quadro P4000 was nothing short of colossal – 3.53 times faster in the CUDA test. As the P4000 does not have dedicated RT cores, it could not run the RTX test.
