Buy the NVIDIA RTX PRO 4000 Blackwell 24 GB: single-slot card, price by written quote

RTX PRO 4000 Blackwell price and supply in the EU

The NVIDIA RTX PRO 4000 Blackwell is a single-slot workstation graphics card with 24 GB of GDDR7 memory, 8,960 CUDA cores and 145 W of total board power. We supply it to companies across the EU. This page prints no price: you receive it as a written quote within one business day, and the quote names the price, the lead time and the warranty terms for the quantity you ask for.

The page is about the card on its own, for IT departments, system builders and integrators who fit it into machines they run or build. A complete tower with two to four of these cards is a different order, and our page to buy an RTX PRO 4000 workstation covers it. The full list of figures is in our RTX PRO 4000 Blackwell specs.

Card, SFF Edition and laptop GPU share the name RTX PRO 4000 Blackwell

A request that says only "RTX PRO 4000" can mean any of the three parts in this table, and one cannot stand in for another.

NVIDIA datasheets 5323450 (June 2026) and 4016700 (August 2025), NVIDIA's quick start guide for RTX PRO Blackwell cards and NVIDIA's "Compare Professional Laptop GPUs" page, as read on 10 November 2026.

The SFF Edition has the same 8,960 CUDA cores and the same 24 GB, but a PCIe 5.0 x8 link, Mini DisplayPort outputs and a lower memory bandwidth. It is the version for half-height slots, and our comparison of the SFF Edition with the other 70 W cards deals with it. The laptop GPU, which NVIDIA calls RTX PRO 4000 Blackwell Generation, has 16 GB and 7,680 CUDA cores; it is a component of mobile workstations and no PCIe card. NVIDIA's Linux driver lists also name an RTX PRO 4000 Blackwell Embedded GPU, which is not the card of this page either. NVIDIA lists neither a Server Edition nor a Max-Q version of the RTX PRO 4000.

The name alone does not settle which part is meant. Put the board power or the format into your request, 145 W single slot or 70 W SFF, and the quote is for the right part. We supply the RTX PRO 4000 Blackwell across the EU; send us the quantity and the systems it goes into and we reply with a written quote within one business day.

The card in the rows a buyer checks

NVIDIA datasheet 5323450 (June 2026); adapter from NVIDIA's quick start guide for RTX PRO Blackwell cards; encode rows from NVIDIA's Video Encode and Decode GPU Support Matrix of 16 October 2026; MIG User Guide (4 November 2026), vGPU supported-GPU list (2 October 2026), RTX PRO Sync Solutions page (15 October 2026) and RTX Enterprise release notes 621.14 (4 November 2026).

Two compute figures are missing from the table on purpose, because NVIDIA's own documents disagree on them. NVIDIA's datasheet (June 2026) gives 1,178 AI TOPS and 37 TFLOPS, its product page 1,290 and 40. AI TOPS is a theoretical FP4 figure with sparsity and no measured rate, so neither number should decide an order. The connector is the one NVIDIA calls PCIe CEM5 16-pin. In inches the card is 4.4 by 9.5; converted, that is about 112 by 241 mm, and NVIDIA publishes no millimetre figure and no weight.

Which orders this card fits

Single slot sets the card apart. On NVIDIA's desktop line-up page of 8 September 2026 it is the only RTX PRO Blackwell card listed as single slot, so four of them occupy four adjacent slots where dual-slot cards need eight slot widths. System builders use that for towers with several separate GPUs, as on our page about four RTX PRO 4000 in one workstation; how the card compares with other one-slot boards is the subject of our single-slot NVIDIA RTX cards comparison.

For CAD and visualisation seats the card brings 24 GB and four outputs that drive four displays at 3840 × 2160 and 165 Hz. Dassault's SOLIDWORKS 2026 certification list, read 10 November 2026, has rows with desktop workstations and the RTX PRO 4000 Blackwell. A row certifies one computer model with one card and one driver, so the check is made per workstation model; our guide to NVIDIA cards for SOLIDWORKS explains how to read the list.

Two further reasons apply to video and display work. The card carries two encoders and two decoders, and NVIDIA's support matrix of 16 October 2026 lists AV1 and 4:2:2 encoding for it with an unrestricted number of sessions. Integrators of display walls and simulators find the card on NVIDIA's RTX PRO Sync page and in the sync table of the 621.14 release notes; NVIDIA's RTX PRO Sync user guide gives the rule as "4000-class and above".

A developer seat for local AI is the fourth case. By our sizing rule the card has a budget of 18.5 GiB for model weights plus KV cache: 0.9 times the memory the driver reports, less 3 GiB. We scale the reported memory from the 95.6 GiB the driver shows on the 96 GB card, which is an assumption, and the driver on the delivered card decides. By file size on Hugging Face, read 10 November 2026, gpt-oss-20b in MXFP4 (12.82 GiB) and Ministral 3 14B Instruct in FP8 (14.65 GiB) lie inside that budget, and Gemma 4 12B-it in BF16 (22.28 GiB) does not. Our article on local LLMs on the RTX PRO 4000 Blackwell goes through the models.

The card is the wrong order where one GPU has to be divided into instances or virtual GPUs. NVIDIA's MIG guide of 4 November 2026 and its vGPU list of 2 October 2026 do not include the RTX PRO 4000.

What the workstation has to provide

• Slot. One full-height slot of single width with room for a 9.5 in card. NVIDIA's quick start guide asks for a PCI Express x16 slot.
• Power. One free 8-pin PCIe lead for the adapter in the box. NVIDIA publishes no power-supply wattage for the card, so add 145 W per card to the load the system already has and compare the sum with the rating its maker gives.
• System memory. The quick start guide asks for at least as much system memory as GPU memory and recommends twice as much, which is 24 GB and 48 GB per card.
• Operating system. NVIDIA's current release notes name Windows 11 from 22H2 to 25H2 and Windows 10 22H2, with Release 620 as the last branch for Windows 10. On Linux they name, among others, Ubuntu 26.04, 24.04 and 22.04 LTS, RHEL and Rocky 10.x, 9.y and 8.y, SLES 16 and 15 SP7, and Debian 13 and 12.
• Driver. The card runs on the NVIDIA RTX Enterprise Production Branch driver. The current Windows releases 621.14 (R620, 4 November 2026), 597.30 (R595, 22 October 2026) and 582.99 (R580, 21 October 2026) all list it. A frozen Linux image needs a look at its driver version: by our reading of NVIDIA's product lists, the first Linux releases that name the card are 570.169, 575.64 and 580.65.06 in their branches.

If the card goes into machines you already run, tell us the workstation models and how many cards each should take, and the written quote names the matching version of the card.

What the written quote contains and what the price depends on

The quote is a written document, sent within one business day of your request. It states the price for the quantity you named, the lead time and the warranty terms; quantities and lead time are confirmed in writing with the quote. The card is available to order.

The price depends on the quantity, the delivery address and the date of the order. For that reason we print no list price and no MSRP figure here, and a budget should rest on a quote for your own quantity and date. A card built into a workstation is a separate line in a quote for the whole system, which our workstations and servers built to order page describes.

A request that can be quoted without a second round contains four things: the number of cards (tell us how many you need), the version (145 W single slot or 70 W SFF), the systems the cards go into, and the delivery address with the company that receives the invoice. The same points for other NVIDIA cards and servers, and what NVIDIA itself publishes, are set out in our guide to requesting NVIDIA GPU quotes in Europe.

Contract, delivery, warranty and larger quantities

An order runs on one European contract, and the invoice comes from Austria. We deliver anywhere in the EU; other destinations go through our logistics partner. The manufacturer warranty is handled through us, and a card that arrives dead is replaced. The first consultation is free of charge, which helps when the choice between this card and one of its neighbours is still open.

IT departments that equip a fleet of CAD seats and system builders who fit the card into their own towers need larger quantities, and we supply those as well. Name the total and the systems; the quote then covers the whole quantity with its lead time. Our page on NVIDIA RTX cards in volume for system builders describes that kind of order.

The cards above and below it

Three cards we supply are the usual alternatives: the NVIDIA RTX PRO 2000 Blackwell one step below, the NVIDIA RTX PRO 4500 Blackwell Workstation Edition one step above, and the NVIDIA RTX 4500 Ada Generation with the same 24 GB.

NVIDIA datasheets 5322351 (June 2026), 5323450 (June 2026), 5108623 (April 2026) and 2895216 (October 2023).

The RTX PRO 2000 Blackwell draws its 70 W without a power cable and is 2.7 in high. Its details are on our page to buy the RTX PRO 2000 Blackwell and in its specs; the direct comparison is RTX PRO 2000 vs RTX PRO 4000 Blackwell.

The RTX PRO 4500 Workstation Edition takes two slot widths for its 32 GB and comes with an adapter from two 8-pin PCIe cables. See the page to buy the RTX PRO 4500 Blackwell, its 32 GB spec page and RTX PRO 4000 vs RTX PRO 4500 Blackwell.

The RTX 4500 Ada has its 24 GB on GDDR6. Against it the RTX PRO 4000 has the higher memory bandwidth, the lower board power, one slot instead of two, PCIe 5.0 and DisplayPort 2.1b instead of PCIe 4.0 and DisplayPort 1.4a, and 4:2:2 encoding, which NVIDIA's matrix does not list for Ada cards. The Ada card remains a sound order for companies that have validated their software and images on it: buy the RTX 4500 Ada, RTX 4500 Ada specs. Owners of the older single-slot RTX 4000 Ada find the generation step in our RTX PRO 4000 Blackwell vs RTX 4000 Ada comparison. If you are undecided between two of these cards, describe the application and the chassis and we quote the one that fits, or both.
