Entry‑Level RTX‑Powered Workstation GPU
The NVIDIA RTX A400 4GB GDDR6 is a compact, low‑power professional graphics card designed for entry‑level and small‑business workstations running CAD, BIM, AEC, 2D/3D visualization, and light media editing. Built on NVIDIA’s Ampere GPU architecture, it combines 768 CUDA cores, 24 third‑gen Tensor Cores, 6 second‑gen RT Cores, and 4 GB of GDDR6 memory to deliver smooth viewport performance and AI‑accelerated workflows in applications such as AutoCAD, Revit, SketchUp, SolidWorks, and basic video editing. The card fits in space‑constrained and compact towers while still offering RTX‑class features such as real‑time ray tracing and AI acceleration for visualization.
4 GB GDDR6 & Entry‑Level Professional Workloads
The RTX A400 4GB uses 4 GB GDDR6 over a 64‑bit bus, providing ~96 GB/s memory bandwidth. This is enough for modest 3D models, 2D drafting, light rendering, and basic media timelines, but not heavy, high‑poly‑scene workloads or 8K‑resolution editing. The 4 GB VRAM suits tasks like CAD schematics, architectural plans, and 2D/1080p‑1440p visualizations, where assets are not extremely complex. For heavy 4K/8K media or dense 3D scenes, users should look to higher‑tier workstation GPUs, but the A400 serves as a cost‑effective entry for small offices and first‑time RTX adopters.

4 × Mini DisplayPort & Multi‑Monitor Use
The RTX A400 features 4 × Mini DisplayPort 1.4a outputs, supporting up to 4 × 5120 × 2880 (5K) @ 60 Hz or 4 × 4096 × 2160 (QHD) @ 120 Hz. This makes it ideal for multi‑monitor professional setups such as CAD/BIM desks, trading stations, and control‑room displays. The card also supports 4K 60 Hz HDR and AV1 decode, plus HDCP 2.2 for secure playback. The NVIDIA Mosaic multi‑display technology enables seamless spanning across multiple monitors, while RTX Desktop Manager helps manage layouts and virtual desktops.
RTX, AI, and Media Engine Features
Thanks to Ampere, the RTX A400 supports second‑gen RT Cores for basic ray‑traced views and third‑gen Tensor Cores for AI‑driven denoising, upscaling, and acceleration in compatible pro‑apps. The card includes 1 × NVENC encoder and 1 × NVDEC decoder with AV1 decode support, enabling smooth playback and light streaming‑ready workflows. The NVIDIA RTX IO technology helps speed up asset loading in supported applications, and the RTX Experience / RTX Desktop Manager stack provides professional‑oriented controls and monitoring.
Power, Form Factor & Compatibility
The RTX A400 4GB runs on PCI Express 4.0 x8, drawing up to 50 W total board power without requiring any external power connector. The single‑slot, low‑profile form factor (about 2.7″ H × 6.4″ L) fits in many compact and OEM‑style workstations, including Dell, Lenovo, and HP systems. The active single‑fan cooler keeps thermals under control under light‑to‑moderate loads, though it can become noticeable under sustained GPU‑compute or viewport‑rendering work. The card is optimized for Windows 10/11 64‑bit and NVIDIA RTX/Quadro workstation drivers, certified for stability with CAD, BIM, and AEC software.
