ASUS ROG Astral GeForce RTX 5080 16GB GDDR7

The ASUS ROG Astral GeForce RTX 5080 O16G GAMING is a graphics card built on the Blackwell architecture for high-resolution gaming and content creation. It delivers 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit interface for demanding workloads.

Thermals noise and power draw in normal use

The card connects through a PCI Express 5.0 x16 slot and supports DirectX 12 Ultimate with OpenGL 4.6 for modern API features. Display outputs include 2 x HDMI 2.1b and 3 x DisplayPort 2.1a driving up to four monitors at 7680 x 4320 resolution.

16GB GDDR7 memory for 4K and AI workloads

The 16GB 256-bit GDDR7 frame buffer running at 30 Gbps effective clock is the specification that determines suitability for 4K gaming with DLSS 4.0 and large-model GPU compute tasks. This capacity and bandwidth combination defines the card's practical ceiling for texture-heavy scenes and inference batch sizes.

Questions about this item

How do I seat the card in a PCI Express 5.0 x16 slot without bending the board?

Align the gold fingers with the slot, press evenly on both ends until the retention clip clicks, then secure the bracket screw before connecting any power cables.

When will the 16GB GDDR7 memory or the 10752 CUDA cores need replacement under normal gaming loads?

The GPU and memory are soldered to the board and are not user-replaceable; the card is designed to last the product's usable life without component swaps.

At what point does the 30 Gbps effective memory clock hit a thermal limit during sustained 4K rendering?

The Blackwell architecture and GDDR7 memory are engineered to maintain the 30 Gbps clock within the card's thermal design; throttling only occurs if case airflow is insufficient.
