ASUS ROG Astral GeForce RTX 5080 16GB graphics card

16GB GDDR7 graphics card for 4K gaming

The ASUS ROG Astral GeForce RTX 5080 delivers 16GB of GDDR7 memory on a 256-bit bus with an effective clock of 30 Gbps. It runs on the Blackwell architecture with 10752 CUDA cores and boost clocks of 2640 MHz in default mode or 2670 MHz in OC mode. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern titles.

Check PCIe 5.0 slot and 2.1b display cables

Verify your motherboard provides a PCI Express 5.0 x16 slot for full bandwidth. Ensure your power supply meets the card’s requirements and that your chassis has enough length clearance. For 4K high-refresh displays use the two HDMI 2.1b or three DisplayPort 2.1b outputs with certified cables.

Suits 4K creators and high-refresh gamers

This model suits enthusiasts targeting 4K gaming at high frame rates and content creators who need 16GB VRAM for rendering workloads. Users with PCIe 4.0 platforms or modest power supplies should consider a lower-tier card. Builders needing more than four displays or different output mixes should look elsewhere.
