Which RTX PRO Blackwell GPU for CAD: SOLIDWORKS, Siemens NX and Revit workstations

The card for a CAD seat, in brief

For most SOLIDWORKS, Siemens NX and Revit seats an NVIDIA RTX PRO 2000 or RTX PRO 4000 Blackwell is enough; the RTX PRO 4500 and 5000 earn their place with very large assemblies on 4K screens, GPU rendering, simulation or a local AI model beside CAD. What matters before the tier is that the workstation model, the card and the driver appear together on the CAD vendor's certification list, because SOLIDWORKS, Siemens and Dassault Systèmes certify whole machines.

This guide is for engineering and architecture firms that equip physical CAD workstations. Virtual CAD desktops on GPU servers with vGPU are a different design, covered in our guide to GPU servers for engineering firms.

What the CAD vendors certify

Each vendor publishes its own list, and they work differently. We read all four on 24 October 2026.

SOLIDWORKS hardware certification and system requirements pages, Siemens support article PL8520247 (revision 2, 11 November 2020) and its certification section, Dassault Systèmes "April 2026 - Certified Workstations", Autodesk Revit 2027 product details; all read 24 October 2026.

SOLIDWORKS. The hardware certification search lists SOLIDWORKS 2026 as the current release and 865 configurations in its results, filtered by workstation maker, model and graphics card, each row with a recommended driver; its card filter offers the RTX PRO 2000, 4000, 4500, 5000 and 6000 Blackwell. RealView and Enhanced Graphics Performance depend on SOLIDWORKS recognising the professional card, and Puget Systems notes that a workstation card is "the only way to get official support for features like Realview and Ambient Occlusion". For SOLIDWORKS 2020 and later the page offers a graphics support patch for a professional card that is "not recognized for RealView and Enhanced Graphics Performance". The system requirements page points to "Certified cards and drivers" for graphics, asks for 16 GB of RAM with 32 GB recommended, and recommends SSDs.

Siemens NX. Siemens' support article on running NX on Windows states that "only certified machines, and never individual hardware components, are certified" and points to the NX graphics certification table, whose matrix shows the machine and adapter per Windows version. It tells users to download the latest certified driver from NVIDIA themselves, because machines do not arrive with it, and to install "the driver for the workstation class graphics adapter and not the gaming adapter". The article dates from 2020, and we could not open the table itself, so ask Siemens or your reseller for the current matrix.

Dassault Systèmes' monthly list. The list of workstations certified in April 2026 separates certified configurations from derived ones; the page names no product or release and does not define "derived".

Dassault Systèmes, "April 2026 - Certified Workstations", read 24 October 2026. The page lists no driver versions.

Autodesk Revit. The Revit 2027 product page gives requirements by video memory rather than a list of cards: a DirectX 11 card with Shader Model 5 and "minimum of 4GB of video memory recommended" for the entry configuration, 6 GB for its value configuration and 8 GB for its performance configuration, and for accelerated graphics "8GB or more of video memory recommended. OpenGL 4.5 or higher required". The processor should have the "highest single core base clock speed" available, and memory runs from 16 GB to 64 GB or more.

In practice this means a firm that standardises on one workstation model from the lists, with one card and one driver, stays inside every vendor's support. A workstation built to order with the same card and driver does not appear by model on these lists. If your CAD support contract requires a certified machine, choose a listed model. We supply the RTX PRO cards for those towers and build the other seats to order; ask us with the workstation model and CAD release, and we check the card against the vendor's list.

Which RTX PRO tier for which assembly

Puget Systems, which builds CAD workstations, publishes a card table for SOLIDWORKS by assembly size and screen resolution, with the goal of "smooth frame rates (>30fps) under most circumstances".

Puget Systems, SOLIDWORKS hardware recommendations, modified 29 April 2026, read 24 October 2026. Puget notes the table is "based on SOLIDWORKS 2019 with "Enhanced graphics performance" enabled".

For Revit, Puget recommends "a mid-range professional card such as the NVIDIA RTX PRO 2000 or 4000 Blackwell" for most users and the 4500 or 5000 for GPU rendering inside Revit, and states that "the video card requirements for Revit are relatively low". It adds that for most Revit users a consumer card would do; for a company fleet, the reasons it gives for RTX PRO cards are "increased reliability, more VRAM, and better compatibility" with other applications. Its suggested Revit system pairs an RTX PRO 4000 Blackwell with 64 GB of memory.

Memory is rarely the limit for the CAD viewport itself. The largest amount any of these vendors asks for is 8 GB, for Revit's performance configuration and accelerated graphics, and the RTX PRO 2000 has twice that. Memory starts to matter when the same card renders, runs a simulation on the GPU or holds a language model, which is where the 32 GB RTX PRO 4500 and the 48 or 72 GB RTX PRO 5000 come in. The RTX PRO 2000 and its 70 W sibling, the RTX PRO 4000 SFF, draw their power from the slot and fit small-form-factor workstations; our comparison of the 70 W cards sets them side by side.

What the measurements show

Puget Systems' engineering roundup of 18 December 2025 tested the RTX PRO 2000, 4000, 4500, 5000, 6000 Max-Q and 6000 Workstation Edition against the Ada generation and other professional cards, in Revit 25.3, Inventor 29.0 and SOLIDWORKS 2024 SP5 with SPECapc, on one desktop workstation with NVIDIA driver 573.92.

Puget Systems, 2025 Professional GPU Engineering Roundup, 18 December 2025, read 24 October 2026; SOLIDWORKS tested at 4K with 150 per cent scaling.

Two conclusions follow. Between the RTX PRO tiers the CAD viewport hardly changes: an RTX PRO 6000 does not make Revit or Inventor graphics faster than an RTX PRO 4000. And a firm replacing Ada cards gains most in SOLIDWORKS with the midrange cards. Puget also found AMD's professional cards ahead in several AEC tests and wrote that NVIDIA's Blackwell cards "struggled to differentiate themselves from their last-gen, Ada-based counterparts" there; for rendering, by contrast, the same publisher measured the RTX PRO 4000 Blackwell 83 per cent ahead of the RTX 4000 Ada in V-Ray GPU and 40 per cent in Blender, as our RTX PRO 4000 comparison records.

We supply the RTX PRO 2000, 4000, 4000 SFF, 4500 and 5000 for CAD workstations across the EU; send us the applications, the largest assembly and the screens per seat, and our team replies with the card and driver we would standardise on.

The processor and memory matter as much

CAD modelling is bound by the processor's clock more than by its core count. Puget writes that SOLIDWORKS modelling "is not able to utilize more than a handful of cores" and runs fastest on "a CPU that has a high operating frequency", while simulation and rendering gain from more cores. For Revit it recommends "a high frequency CPU – regardless of the core count", and Autodesk asks for the highest single-core base clock. Spend on the processor before moving a CAD seat from an RTX PRO 4000 to a 4500.

Drivers for a CAD fleet

NVIDIA's RTX Enterprise driver page states that NVIDIA works with software and hardware partners "to tune, test, and certify our drivers" for professional applications, and that each driver goes through "hundreds of rigorous test plans". The CAD vendors name the driver that belongs to a certified configuration: SOLIDWORKS lists a recommended driver per row, Siemens asks for the latest certified one. For a fleet that means one driver version, chosen from the CAD vendor's list for the release you run, rolled out to every seat at once and changed only when you move to a new CAD release.

NVIDIA's Enterprise Management Toolkit (NVWMI) lets IT administrators configure GPU settings across the network, and RTX Desktop Manager handles single and multi-display desktops. Every card in this guide has four DisplayPort 2.1b outputs, full-size or Mini, so two or three screens per seat are within reach of each tier.

When a larger card pays off

• GPU rendering on the desk. Rendering scales with cores and memory, unlike the viewport; for GPU-based rendering inside Revit, Puget recommends the RTX PRO 4500 or 5000.
• Large assemblies on 4K screens. Puget's table moves to the RTX PRO 5000 for assemblies over 10 million triangles at 4K.
• Simulation on the GPU. Solvers that run on the GPU need memory for the mesh; Ansys' guidance on this is in our engineering firms guide.
• A local AI model beside CAD. A 14B model in FP8 needs about 16 GB for its weights alone, so it shares a 24 GB card badly with a CAD session; our guide to the best workstation GPU for AI covers that choice.

For a team that renders, simulates or runs models together, one shared machine can replace several large cards at the desks; our comparison of a GPU server or workstations for a team works through that decision.

Power and form factor for many seats

The RTX PRO 2000 draws at most 70 W through the PCIe slot and needs no power cable, which suits compact workstations under every desk. The RTX PRO 4000 draws 145 W through one 16-pin connector in a single slot, the 4500 200 W and the 5000 300 W in two slots. For twenty seats the cards alone come to 1.4 kW with the RTX PRO 2000 and 2.9 kW with the RTX PRO 4000, by our arithmetic from NVIDIA's board power, spread over the office rather than in one room. Our pages to buy an RTX PRO 4000 workstation and to buy an RTX PRO 4500 workstation cover multi-card towers for rendering and AI.

What we supply for CAD workstations

We supply the RTX PRO 2000, 4000, 4000 SFF, 4500 and 5000 Blackwell on one EU contract and invoice with manufacturer warranty, for the certified workstation models your firm runs, and build workstations to order where a certified model is not required. Quantities and lead time are confirmed in writing with the quote. For a fleet, tell us the CAD applications and releases, the number of seats and the workstation model, and we quote the cards for every seat in one offer.
