NVIDIA RTX A400 4GB GDDR6 workstation Black
The Ampere-based RTX A400 delivers hardware-accelerated ray tracing and 768 CUDA cores in a compact, single-slot, 163mm design with a 50W TDP that requires no external power. Its low-profile, blower-cooled form factor and four Mini DisplayPort 1.4a outputs make it a practical choice for driving multi-display digital signage or financial trading setups. This card is best for entry-level workstation users needing certified drivers for basic 3D modeling and CAD, not for gaming or heavy content creation.
