PNY NVIDIA Quadro RTX 4000 - The World’S First Ray Tracing GPU

Product Information

The embedded OpenCL Just-In-Time compiler will offer an opt-in version utilizing CLANG 7.0 and NVVM 7.0 components, providing support for 16-bit floating point and 128-bit integer data types. 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. Turing SM Architecture (streaming multi-processor design that delivers greater processing efficiency) RT Cores — enable real-time ray tracing of objects and environments with physically accurate shadows, reflections, refractions and global illumination.

NVIDIA today introduced the Quadro RTX 4000 graphics card — the company’s first midrange professional GPU powered by the NVIDIA Turing architecture and the NVIDIA RTX platform.Producing a single ray traced quality photoreal image used to take seconds or even minutes, but this was now being done in a fraction of a second on a desktop workstation, albeit one with two very powerful GPUs. Nvidia had shown it could make photorealistic visualisation completely interactive and while there was almost certainly some smoke and mirrors, it was a massive advancement. But the Nvidia Quadro RTX 4000 isn’t flawless. It doesn’t maintain such a commanding lead when AI denoising is enabled, especially when rendering with few passes. And in some cases it’s even slower. Considering the RTX 4000 is all about deep learning, we found this very surprising. As far as AI denoising is concerned we can only presume the GPU will come into its own when the Tensor cores are put to full use in RTX optimised software. It’s certainly too early to judge it on this. It’s important to note that the Quadro RTX GPUs are more power hungry than the Pascal Quadros they replace. The max power consumption for the RTX 4000, for example is 160W, compared to the 105W of the Quadro P4000. The top-end RTX 8000 can go all the way up to 295W.

There are no hard and fast rules here as to what the RTX 4000 will be able to handle in SolidWorks Visualize, but if you’re currently pushing the limits of other 8GB GPUs, such as the Quadro M4000 or P4000, then you’ll probably need to look at the 16GB Quadro RTX 5000 or even higher. Alternatively, get smarter about how you optimise your scene. Multitasking – Nvidia Quadro RTX 4000Both viewing styles are more GPU-intensive, so performance is less limited by the frequency of the CPU. In our tests, we saw a bigger benefit over older GPUs. With RealView, Shadows and Ambient Occlusion enabled the Nvidia RTX A4000 was 1.16 times faster than the Quadro RTX 4000 and 1.57 times faster than the Quadro P4000.

The board also features four DisplayPort 1.4a ports and is cooled by a single ‘blower’ type fan, but only draws in cool air from one side of the card. Nvidia Quadro RTX still has thousands of CUDA cores, so it can do all the things that Pascal and Maxwell could do (albeit faster) but it also features two additional sets of cores — RT Cores, which are optimised for ray tracing, and Tensor Cores, which are optimised for deep learning. The 20 FPS it delivered was impressive but, at times, the model stuttered, particularly when transitioning from the interior to the exterior of the commercial development. However, as with most applications, you can dial down the visual quality in Enscape to increase performance. For example, when set to draft, which still gives very good visual results, we achieved 36 FPS and everything was silky smooth.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. Redshift - support for Redshift RT, a real time rendering feature that allows 3D artists to visualize scenes in real time, omitting unnecessary wait times for renders to finalize 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. 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.
