Lenovo NVIDIA RTX A400 4 GB GDDR6 | Compact Professional Graphics Solution

The Lenovo NVIDIA RTX A400 4 GB GDDR6 is a compact, single-fan graphics card built for creative professionals and technical users who need reliable 4K performance without excessive power draw. Based on NVIDIA’s Ampere architecture, it delivers hardware-accelerated ray tracing and AI features in a half-length, full-height form factor.

Specification Overview

Compact Design for Tight Builds

The RTX A400’s half-length, full-height form factor makes it ideal for small-form-factor workstations and rack-mounted systems where space is limited. At just 250 g and with a single active fan, it balances cooling performance with low noise output. The card’s 50 W typical power consumption means it can run from a PCIe slot without requiring external power in many setups, though a 16-pin supplementary connector is included for added stability.

Professional-Grade Display Connectivity

With four Mini DisplayPort 1.4a outputs, this card can drive up to four 4K displays simultaneously at 60 Hz, or a single 8K display at 60 Hz. This makes it well-suited for financial traders, content creators, and technical professionals who need expansive screen real estate. The 7680 x 4320 maximum resolution ensures crisp detail whether you’re editing 4K video or monitoring multiple data feeds.

Ray Tracing and AI Acceleration

Built on NVIDIA’s Ampere architecture, the RTX A400 includes dedicated RT cores for hardware-accelerated ray tracing and Tensor cores for AI processing. These features enable faster rendering in compatible applications, smoother real-time previews, and accelerated workflows in software that leverages NVIDIA’s CUDA parallel computing platform. The 768 CUDA cores provide ample processing power for professional applications without the cost of higher-end workstation cards.

Windows Compatibility and Reliability

The card supports Windows 10, Windows 11, and even Windows 7, making it compatible with both modern and legacy professional systems. Active cooling with a single fan maintains optimal temperatures during extended workloads, while the full-height bracket ensures secure mounting in standard ATX cases. ECC memory protection helps prevent data corruption in critical applications.
