Launched in March of 2023, the NVIDIA RTX 4000 SFF Ada Generation GPU is the mini version of the single-width NVIDIA RTX 4000 Ada generation GPU. It offers the same 20GB of GDDR6 memory as the larger version but can be installed in a smaller chassis or you can stick with a full-scale chassis too. The only difference between the SFF version and the full size single-width RTX 4000 Ada is the memory bandwidth.
With 4x mini-DisplayPort 1.4a, the NVIDIA RTX 4000 SFF Ada Generation can power 4x 4K monitors at 120Hz, 4x 5K monitors at 60Hz, or 2x 8K monitors at 60Hz. The GPU is VR ready for real-time rendering and features ISV certification for a number of complex software applications.
This card features 20GB of GDDR6 ECC memory. Memory bandwidth for the NVIDIA RTX 4000 SFF Ada Generation is listed at 280GB/s with a 160-bit memory interface. For the larger NVIDIA RTX 4000 Ada, the memory interface is still 160-bit but memory bandwidth is at 360GB/s, 80GB/s faster than on the SFF version. Single-precision performance is listed at 19.2 TFLOPS, RT Cores performance at 44.3 TFLOPS, and Tensor Core performance at 306.8 TFLOPS, just slightly less than the full-sized version.
The NVIDIA 4000 SFF Ada has active cooling with an integrated fan. A 70W power draw is provided directly to the card through the PCIe 4.0 x8 slot on the system board and requires no additional power cables. A minimal host power supply unit of 250W is recommended.
