21330-01-20G

High-Performance PCIe 4.0 Workstation GPU Add-in Card for RDNA 3 Visualization and Compute with the 21330-01-20G

The 21330-01-20G is a Sapphire full-height PCIe 4.0 x16 graphics add-in card built around the AMD Radeon RX 7800 XT (RDNA 3, 5 nm) architecture to support dense workstation visualization and GPU-accelerated development. With 3840 stream processors and a 16GB GDDR6 memory subsystem on a 256-bit bus, the 21330-01-20G is engineered for predictable throughput in content creation pipelines and interactive 3D workloads while retaining strong FP32 and FP16 performance for compute-oriented toolchains.

Architecturally, the 21330-01-20G balances memory bandwidth (624 GB/s) with host-side scalability through PCIe 4.0, enabling efficient asset streaming and reduced CPU-GPU synchronization overhead in modern engines and GPU APIs. The 2.5-slot mechanical envelope in a full-height form factor aligns with enterprise tower and rack workstations where airflow planning is critical, while dual-fan air cooling targets sustained clocks under continuous loads. For multi-display production environments, the 21330-01-20G provides 1x HDMI 2.1 and 3x DisplayPort 2.1 to drive up to 4 monitors, supporting high-resolution output up to 7680 x 4320 with HDCP 2.3 compliance.

Why Choose the 21330-01-20G?

The 21330-01-20G delivers a practical density-to-performance profile for teams standardizing on PCIe 4.0 workstations that need reliable graphics acceleration and compute capability without moving to datacenter-class platforms. Its 16GB VRAM capacity, modern API support (DirectX 12 Ultimate, Vulkan 1.3, OpenCL 2.2), and predictable power design (263W with 2x 8-pin PCIe) simplify deployment planning across mixed visualization and development estates.

Sapphire focuses on robust board engineering, validated component selection, and thermal design discipline to align with enterprise reliability expectations and contemporary data center and workstation standards for serviceability, stability, and long duty-cycle operation.

Key Applications:

Multi-monitor desktop visualization
3D content creation and rendering
CAD and design workflows
