ROG Astral GeForce RTX 5080 OC Edition

The ASUS ROG Astral GeForce RTX 5080 OC Edition is a graphics card built on the Blackwell architecture with 10752 CUDA cores. It carries 16GB of GDDR7 memory running at 30 Gbps across a 256-bit interface. The card targets enthusiasts and professionals who need high frame rates at 4K and beyond.

PCI Express 5.0 x16 interface and display outputs

It installs in a PCI Express 5.0 x16 slot and provides two HDMI 2.1b ports plus three DisplayPort 2.1a connectors for up to four simultaneous displays at 7680 x 4320 resolution. The Blackwell architecture and DLSS 4.0 support free the CPU from heavy upscaling work and enable ray-traced titles at playable speeds. A robust power supply and adequate case airflow are required to sustain the factory overclock.

Enthusiast 4K gaming and content creation

This model suits builders who want a 16GB GDDR7 card for 4K gaming, real-time ray tracing and AI-accelerated creative workloads. Users with older PCIe 3.0 platforms, compact cases or modest power supplies should look at something else.

Questions about this item

Will the 256-bit GDDR7 memory at 30 Gbps hit a bandwidth ceiling during sustained 4K gaming?

The 256-bit bus and 30 Gbps GDDR7 deliver high bandwidth that matches the RTX 5080's 10752 CUDA cores for extended 4K workloads.

How loud and hot does the ROG Astral cooler get when the card runs all day at full load?

The ROG Astral cooler uses a large heatsink and multiple fans to move heat away from the GPU, keeping temperatures and noise controlled during long sessions.

What power connectors must my PSU already have for this RTX 5080 to work?

The card requires a native 12VHPWR connector or a 12VHPWR adapter cable from the power supply to deliver the power the RTX 5080 needs.
