ASUS ROG-ASTRAL-RTX5080-O16G-GAMING graphics card

ROG Astral RTX 5080 16GB Overview

The ASUS ROG Astral GeForce RTX 5080 is a high-end graphics card built on the Blackwell architecture. It targets enthusiasts and professionals who need maximum frame rates at 4K resolution and headroom for emerging AI workloads. The 16GB GDDR7 frame buffer connects via a 256-bit bus running at 30 Gbps. A factory overclock pushes the 10752 CUDA cores beyond reference specifications.

16GB GDDR7 Capacity and Headroom

Sixteen gigabytes of GDDR7 memory provides comfortable capacity for current 4K gaming with high-resolution texture packs and for local AI inference models that fit within the frame buffer. The 256-bit interface and 30 Gbps data rate deliver ample bandwidth for rasterisation and ray-tracing workloads. Memory becomes the limiting factor only when datasets or texture sets exceed the 16GB pool, forcing texture streaming or offloading to system RAM.

Quad-Fan Cooling and Display Connectivity

A patented vapor chamber, dense heatsink fins and a phase-change GPU thermal pad work with four axial fans to move heat away from the overclocked core. The thermal solution keeps boost clocks stable during extended sessions without excessive acoustic output. Three DisplayPort 2.1a and two HDMI 2.1b outputs support four simultaneous displays at high refresh rates, enabling multi-monitor productivity or surround gaming from a single card.
