PNY Technologies, Inc. VCNRTX4000ADALP-SB RTX 4000 SFF Ada 20GB workstation graphics card

Compact workstation GPU for professional

The PNY RTX 4000 SFF Ada packs 6144 CUDA cores and 20GB GDDR6 memory into a small-form-factor design. It targets engineers and creators who need certified application performance inside space-constrained workstations. The 70W maximum power draw keeps thermal demands modest for dense builds.

Single-slot PCI-E 4.0 installation with 70W envelope

The card plugs into a standard PCI-E 4.0 x16 slot and draws all power from the slot itself, so no external connectors are required. Builders must verify that the chassis can accommodate a full-height, single-slot card and that the motherboard firmware supports PCI-E 4.0 signalling. Airflow restrictions in tight enclosures are the most common cause of thermal throttling.

280 GB/s bandwidth caps sustained compute throughput

The 280 GB/s memory interface feeds 192 Tensor Cores and 48 RT cores, but bandwidth becomes the limiting factor for large dataset streaming. Workloads that exceed the 20GB frame buffer will spill to system memory across the PCI-E 4.0 bus, adding latency. Buyers needing more VRAM or multi-GPU scaling should consider larger form-factor alternatives.
