About the NVIDIA RTX A400 4GB GDDR6 PCIe Gen4
The NVIDIA RTX A400 features 4GB GDDR6 memory with 112 GB/s bandwidth, delivering professional-grade graphics acceleration in a compact, power-efficient form factor. Built on NVIDIA's Ampere architecture, this PCIe Gen4 x8 GPU combines 768 CUDA cores, 24 second-generation RT cores, and 96 third-generation Tensor cores to accelerate workloads across design, visualization, and AI inference tasks. With zero external power requirements and a 50W TDP, the RTX A400 (part number 900-1G123-2500-000) integrates seamlessly into space-constrained enterprise environments without demanding additional PSU capacity.
The RTX A400 excels in professional visualization and compute-intensive applications certified for Autodesk AutoCAD, Revit, and similar industry-standard software. Its low-profile half-height form factor fits single-slot configurations, making it ideal for dense server deployments where IT procurement teams and design infrastructure specialists need reliable GPU acceleration without chassis redesigns. Four Mini DisplayPort 1.4 outputs support up to 8K resolution at 60Hz across four simultaneous displays, enabling multi-monitor professional workflows. NVIDIA's comprehensive API support—including CUDA 11, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3—ensures broad application compatibility across Windows and Linux environments. Active cooling via a single integrated fan maintains optimal thermal performance in continuous-duty scenarios.
