HP Inc 6Q3U4AA AMD Radeon RX 6400 4GB Dp+hdmi GFX

HP Inc 6Q3U4AA AMD Radeon RX 6400 4GB Graphics Card

Overview

The HP Inc 6Q3U4AA is a low-profile discrete graphics card built around AMD's Radeon RX 6400 GPU with 4GB of dedicated video memory. It ships with both a DisplayPort and an HDMI output, giving you two independent display connections from a single card — a practical fit for compact workstations or systems where slot count is limited. This is a factory-new, genuine HP Inc component sourced through commercial distribution channels.

The 4GB frame buffer handles standard-resolution display workloads without demanding additional system resources. The dual-output configuration — DisplayPort paired with HDMI — means you can connect a primary monitor on DP and a secondary or presentation display on HDMI simultaneously, without a dock or adapter chain in between.

Key Features

• 4GB Dedicated Video Memory: Provides a dedicated frame buffer separate from system RAM, reducing contention on CPU-integrated graphics and allowing stable dual-display operation without memory pressure on the host system.
• DisplayPort + HDMI Outputs: Two independent outputs let you drive two monitors natively — DP for a primary workstation display, HDMI for a secondary screen or presentation panel — without requiring an MST hub or adapter.
• Compact Form Factor: At 152mm card length, the 6Q3U4AA fits in small-form-factor and micro-tower chassis where full-length cards are excluded, broadening deployment options in space-constrained environments.
• AMD Radeon RX 6400 GPU: Built on AMD's RDNA 2 architecture, the RX 6400 supports hardware-accelerated decoding workloads and modern display standards appropriate for office and light commercial workstation use.

The HP Inc 6Q3U4AA is a compact Radeon RX 6400 card with 4GB of dedicated VRAM — the detail that matters most here is the 152mm card length, which is what determines whether this card physically fits your target chassis before you ever think about GPU performance.

Technical Highlights:

• 4GB VRAM: Dedicated frame buffer keeps display workloads off system memory — relevant in workstations running multiple applications alongside dual displays.
• Dual Display Outputs (DP + HDMI): Native two-output configuration eliminates the need for adapters or MST hubs in standard dual-monitor deployments.
• 152mm Card Length: Short enough for SFF and micro-tower systems where standard-length cards are physically excluded — verify your chassis clearance spec before ordering.

Deployment Considerations:

• Confirm your target chassis supports the card's physical slot type and power connector requirements — the distribution record does not specify PCIe version or auxiliary power needs, so cross-reference HP's product documentation before procurement.
• The RX 6400 is positioned for light display workloads; if your deployment involves GPU-accelerated compute, video analytics, or high-resolution multi-stream decode at scale, a higher-tier card in the Radeon or equivalent lineup will be needed.

Best fit for compact commercial workstations or SFF deployments requiring a discrete dual-output display upgrade where a sub-152mm card length is a hard chassis constraint.
