Low-Profile Dual-Slot PCIe 4.0 GPU Add-in Card for Dense Edge and VDI Endpoints with the GV-R64D6-4GL

The GV-R64D6-4GL is a low-profile, dual-slot GPU add-in card designed for space-constrained enterprise systems that still require reliable graphics acceleration and modern display connectivity. Built on AMD RDNA2 in the RX 6000 Series, it targets 1U/2U short-depth servers, compact workstations, and SFF endpoints where power headroom and airflow are limited, while maintaining a consistent driver model for managed fleets.

Architecturally, the GV-R64D6-4GL pairs a PCIe 4.0 x16 mechanical interface with an x4 electrical link, aligning well with platforms where lanes are reserved for NVMe backplanes or high-speed networking. Its 4GB GDDR6 memory on a 64-bit interface provides predictable frame-buffer capacity for entry-level VDI graphics, multi-display desktops, and light media pipelines. With HDMI 2.1 and DisplayPort 1.4a, the card supports dual outputs up to 8K UHD, enabling signage or control-room nodes without adding external adapters. A 53W board power profile and no auxiliary PCIe power connector simplify deployment in OEM chassis and reduce PSU and cabling constraints.

Why Choose the GV-R64D6-4GL?

The GV-R64D6-4GL delivers a practical density-to-performance balance for enterprises standardising on low-profile expansion across edge and branch locations. Its low-power design supports stable operation in thermally restricted enclosures, while PCIe 4.0 compatibility preserves forward alignment with current server generations and scalable I/O topologies.

Gigabyte engineering focuses on board-level reliability, validated thermals, and controlled component selection to support continuous operation in modern data centre and edge environments. The design is optimised for predictable integration, consistent mechanical fit, and operational stability under managed change control.

Key Applications:

• Entry-level VDI and remote desktop graphics
• Digital signage and multi-display kiosks
• Edge compute visualization nodes
• Light media transcode and content review
• Compact workstation graphics acceleration
