The ability for real-time ray tracing is driving the greatest advancement in computer graphics in almost two decades. The amazing horsepower of Z by HP Workstations combined with the new capabilities of one or more Quadro RTX 4000 GPUs means millions of creatives, engineers and other professionals can create their best work ever.” Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

Pro driver feature dramatically increases 3D performance by dynamically reducing viewport resolution Assimilate Scratch]: The application may crash due to a kernel exception in the NVIDIA OpenGL driver. Nvidia RTX is being used to massively accelerate classic viz focused ray trace renderers like V-Ray, KeyShot and Solidworks Visualize, which we test below. However, some of the more exciting developments are coming from the AEC sector in tools like Enscape, Chaos Vantage and Unreal Engine, which really make ray tracing ‘real-time’. Vantage, for example, is built from the ground up for real-time ray tracing so can maximise the usage of RT cores within the new GPUs.

At this point it’s important to note the relevance of Frames Per Seconds (FPS). Generally speaking, for interactive design visualisation you want more than 24 FPS for a fluid experience. While all the GPUs achieved this at FHD resolution, only the RTX 4000 came close at 4K. 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. Decode acceleration for MPEG-2, MPEG-4 Part 2 Advanced Simple Profile, H.264, HEVC, MVC, VC1, DivX (version 3.11 and The board features four DisplayPort 1.4a ports and can drive up to four displays at 5K resolution. It is cooled by a single ‘blower’ type fan, which draws in cool air from the top and bottom of the card, pushes it through a radiator and then directly out of the rear of the workstation chassis. This is in contrast to most consumer GeForce GPUs which use axial fans that recirculate air inside the machine.

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. 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. GPUDirect for Video speeds communication between the GPU and video I/O devices by avoiding unnecessary system memory Four DisplayPort 1.4 outputs (supporting resolutions such as 3840 x 2160 @ 120 Hz, 5120x2880 @ 60Hz and 7680 x 4320 @ 60Hz)

Graphics Features

The Quadro RTX 4000 is complete overkill for most 3D CAD applications including SolidWorks, which tend to be CPU limited and often work just as well with an entry-level or mid-range GPU like the Quadro P1000 or P2000.
