ROG Astral RTX 5080 16GB GDDR7

The ASUS ROG Astral GeForce RTX 5080 is a graphics card built on the NVIDIA Blackwell architecture. It delivers 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit interface running at 30 Gbps. The card connects via PCI Express 5.0 x16 and supports DirectX 12 Ultimate with DLSS 4.0 for AI-enhanced rendering.

4K creators and high-refresh competitive players

This card suits users who need 16GB of high-bandwidth memory for 4K gaming, 3D rendering or video editing workloads. The four-display output configuration with HDMI 2.1b and DisplayPort 2.1a handles multi-monitor setups at 7680 x 4320 resolution. Buyers targeting 8K gaming or compute tasks requiring more than 16GB VRAM should consider higher-capacity alternatives.

16GB GDDR7 on 256-bit bus

The 16GB GDDR7 frame buffer paired with a 256-bit memory bus determines whether this model fits your workload. At 30 Gbps effective clock the memory subsystem delivers the bandwidth needed for 4K textures and high frame rates. If your applications consistently exceed 16GB VRAM allocation you will need a card with a larger memory buffer.

Questions about this item

What PCI Express slot width does the ROG-ASTRAL-RTX5080-O16G-DHAHAB-CORE require?

The card uses a PCI Express 5.0 x16 slot, so a full-length x16 lane is needed on the motherboard.

Which power connectors must be attached before the first boot?

Connect all required 12VHPWR or 8-pin PCIe cables to the card's power inputs; missing a connector will prevent the GPU from posting.

How often should the thermal paste and pads be inspected on this RTX 5080 model?

Plan to check the thermal interface material every two to three years, or sooner if temperatures rise under load.
