Blackwell 4000 SFF Edition
The RTX PRO 4000 Blackwell SFF is a professional graphics card by NVIDIA, launched on August 11th, 2025. Built on the 5 nm process, and based on the GB203 graphics processor, the card supports DirectX 12 Ultimate. The GB203 graphics processor is a large chip with a die area of 378 mm² and 45,600 million transistors.
Unlike the fully unlocked GeForce RTX 5080, which uses the same GPU but has all 10752 shaders enabled, NVIDIA has disabled some shading units on the RTX PRO 4000 Blackwell SFF to reach the product’s target shader count. It features 8960 shading units, 280 texture mapping units, and 96 ROPs.
Also included are 280 tensor cores which help improve the speed of machine learning applications. The card also has 70 raytracing acceleration cores. NVIDIA has paired 24 GB GDDR7 memory with the RTX PRO 4000 Blackwell SFF, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 577 MHz, which can be boosted up to 1432 MHz, memory is running at 1125 MHz (18 Gbps effective).
Being a dual-slot card, the NVIDIA RTX PRO 4000 Blackwell SFF does not require any additional power connector, its power draw is rated at 70 W maximum. Display outputs include: 4x mini-DisplayPort 2.1b. RTX PRO 4000 Blackwell SFF is connected to the rest of the system using a PCI-Express 5.0 x8 interface. The card’s dimensions are 167 mm x 69 mm x 40 mm, and it features a dual-slot cooling solution.
