Compact dual-slot half-height card with four Mini DisplayPort outputs

NVIDIA

NVIDIA RTX 4000 SFF Ada 20GB graphics card

SKU CH-921W-WQQCJ

Compact half-height GPU with 20 GB GDDR6 ECC, 6144 CUDA cores, 48 RT cores, 192 Tensor cores and four Mini DP outputs at 70 W

  • Chipset ManufacturerNVIDIA
  • 20GB GDDR6 ECC memory with 280GB/s bandwidth ensures data integrity for critical workloads
  • 6144 CUDA cores deliver 19.2 TFLOPS single-precision performance for demanding compute tasks
  • 192 fourth-generation Tensor cores provide 306.8 TFLOPS Tensor performance with FP8 acceleration
  • PCIe 4.0 x16 interface enables high-speed data transfer for data-intensive applications
  • Dual-slot half-height design at 70W powers four 5K@60Hz displays via Mini DP ports

Built for compact workstations

The RTX 4000 SFF Ada 20GB fits dual-slot half-height chassis while delivering 6144 CUDA cores and 20GB GDDR6 ECC memory. It targets professionals who need certified stability for CAD, simulation and AI inference in space-constrained systems.

Sustained load behaviour

A 70W power envelope keeps thermals manageable during long renders or batch inference jobs. The 160-bit bus and 280GB/s bandwidth feed the 192 Tensor cores and 48 RT cores without throttling, while ECC protects data integrity across extended runs.

Check your setup first

Verify the motherboard offers a PCIe 4.0 x16 slot and that the power supply can spare 70W for the card. Ensure the case accepts a dual-slot half-height form factor and that your monitors can connect via the four Mini DP outputs driving up to 5K at 60Hz.

Questions sur cet article

How much heat does the 70W RTX 4000 SFF Ada 20GB add to a workstation running all day?

The card draws 70W, so it adds roughly that much heat to the case; a dual-slot half-height cooler exhausts most of it out the rear bracket.

Does the PCIe 4.0 x16 RTX 4000 SFF Ada 20GB need an external power cable?

No, the 70W limit is satisfied entirely from the PCIe slot, so no auxiliary connector is required.

Will the 4 Mini DP outputs on the RTX 4000 SFF Ada 20GB drive my existing DisplayPort monitors?

Each Mini DP port supports 5K at 60Hz; adapters let you connect standard DisplayPort or HDMI displays without signal loss.
