ASUS ROG Astral RTX 5080 16GB GDDR7 OC

The ASUS ROG Astral GeForce RTX 5080 is a factory-overclocked graphics card built on the Blackwell architecture. It delivers 10752 CUDA cores and 16GB of GDDR7 memory across a 256-Bit interface running at 30 Gbps. The card connects via PCI Express 5.0 x16 and supports DirectX 12 Ultimate and OpenGL 4.6. It targets enthusiasts seeking maximum frame rates at 4K resolution.

Suits 4K high-refresh gaming not compact builds

This card suits builders who prioritise 4K high-refresh gaming and can accommodate a quad-fan cooler with a patented vapor chamber. It fits systems with robust power delivery and enough case length for a large triple-slot design. Builders working in small-form-factor cases or with limited power headroom should look at smaller dual-slot models instead.

16GB 256-Bit GDDR7 at 30 Gbps decides fit

The single specification that decides fit is the 16GB 256-Bit GDDR7 memory subsystem running at 30 Gbps. This combination sets the bandwidth ceiling for 4K texture workloads and high-resolution frame buffers. If your workflow or target resolution demands more memory capacity or a wider bus, this model will not meet that requirement.

Questions about this item

Will the phase-change GPU thermal pad need replacing after heavy use?

The phase-change thermal pad is designed to last the card's lifespan under normal operation and does not have a user-serviceable replacement interval.

What limits sustained performance first on the 16GB GDDR7 memory?

The 256-bit memory interface running at 30 Gbps sets the bandwidth ceiling before the 16GB capacity fills in typical gaming workloads.

How loud does the quad-fan cooler get during all-day rendering?

The four fans and patented vapor chamber keep thermals controlled, allowing lower RPMs than triple-fan designs at equivalent loads.
