NVIDIA RTX A400 Professional Graphics Board

The NVIDIA RTX A400 is a compact, powerhouse workstation graphics card built on the NVIDIA Ampere architecture to deliver unrivaled performance for design, engineering, and creative workflows. Engineered for professionals who require precision, speed, and reliability in a small-form-factor, this card brings real-time ray tracing, AI-accelerated tasks, and rock-solid enterprise stability into tight workstations, compact towers, or compact render nodes. With 768 CUDA cores, 6 second-generation RT Cores, and 24 third-generation Tensor Cores, the RTX A400 accelerates CAD, 3D rendering, virtual prototyping, and data-driven visualization so you can iterate faster, render more accurately, and deliver results with confidence.

• Compact, small-form-factor design: The RTX A400 is purpose-built for dense workstations and space-constrained builds. Its compact footprint frees up room for additional PCIe devices while still delivering robust GPU performance. This makes it ideal for professional studios, labs, and engineering offices where space is at a premium, yet deadlines remain tight. The small form factor does not compromise core capabilities, ensuring you don’t have to sacrifice speed for size.
• High-performance CUDA, RT, and Tensor cores: At the heart of the RTX A400 are 768 CUDA cores that deliver parallel compute power for viewport rendering, simulations, and compute-heavy tasks. Six second-generation RT Cores enable accelerated real-time ray tracing for physically accurate lighting and reflections in design reviews and product visualizations. The 24 third-generation Tensor Cores accelerate AI workloads, denoising, and upscaling, enabling intelligent workflows such as up-resing renders, AI-assisted denoising, and predictive analytics that streamline creative pipelines and engineering analyses.
• AI acceleration and professional-grade rendering: Leverage AI-driven features to speed up complex tasks—from denoising noisy renders to accelerating upscaling and optimization in design previews. The RTX A400 empowers engineers and designers to explore more iterations in less time, improving decision-making and accelerating time-to-market. Whether you’re working on architectural visualization, automotive design, or product prototyping, AI-enabled tools embedded in professional software can dramatically shorten cycle times while preserving fidelity.
• Enterprise reliability and software-forward support: Built for continuous operation in demanding environments, the RTX A400 is designed to deliver consistent performance across prolonged workloads. Enterprise-grade drivers, validated certifications with major CAD and DCC applications, and long-term support help minimize downtime, reduce IT overhead, and ensure smooth collaboration across teams. This reliability is crucial for studios and organizations that must maintain tight release schedules and predictable performance over many quarters.
• Efficiency, cooling, and quiet operation for dense workstations: The RTX A400 is engineered to balance performance and thermals, enabling sustained workloads without excessive noise or heat in constrained rigs. Efficient power management and thoughtful cooling design help protect component longevity while keeping the workstation comfortable for daily, all-day use. In environments where noise discipline matters—presentation spaces, shared studios, or open offices—the RTX A400 helps maintain focus and productivity while delivering peak GPU acceleration.

How to install NVIDIA RTX A400

Installing the RTX A400 is straightforward for most modern workstations. Before you begin, verify you have a compatible PCIe slot and a power supply adequate for your entire system. Power down the workstation, unplug from the wall, and open the chassis. If you are upgrading from an older GPU, remove the existing card and any associated brackets or shrouds to free the PCIe slot. Align the RTX A400 with the PCIe x16 slot and firmly seat it until it is fully plugged in. Secure the card with the appropriate screw on the bracket to prevent movement during operation. If your workstation requires PCIe power connectors for this card, connect the appropriate 6- or 8-pin power cables from the power supply as specified in your system’s manual. Replace the side panel, reconnect the cables, and boot the system. Once the system starts, install the latest NVIDIA drivers from the official NVIDIA drivers page for professional GPUs, selecting the RTX A400 and your operating system. After installation, reboot if prompted and launch a professional application or a GPU diagnostic tool to verify that the card is properly recognized and functioning. To maximize stability and performance, keep the driver software updated and run a CUDA toolkit-enabled test in your primary workflow to ensure the accelerator is recognized by your software stack. If you encounter any base configuration prompts, refer to your motherboard and system documentation to confirm PCIe lane assignments and power delivery requirements. Regular driver updates from NVIDIA help maintain compatibility with the latest professional software optimizations and security updates.
