ROG Astral RTX 5080 16GB GDDR7

The ASUS ROG Astral GeForce RTX 5080 is a graphics card built on the Blackwell architecture for enthusiasts and creators. It carries 10752 CUDA cores and 16GB of GDDR7 memory across a 256-bit interface. The board connects through a PCI Express 5.0 x16 slot and draws up to 360W through a single 16-pin connector.

16GB GDDR7 capacity and headroom

The 16GB frame buffer at 30 Gbps handles 4K gaming and heavy creative workloads with room for high-resolution textures. In OC mode the boost clock reaches 2790 MHz, while default mode sits at 2760 MHz. Memory bandwidth and VRAM capacity become the limiting factor before the GPU compute units in the most demanding ray-traced scenes.

PCI Express 5.0 x16 interface limits

The card uses a PCI Express 5.0 x16 link for host communication. Display outputs comprise 2 x HDMI 2.1b and 3 x DisplayPort 2.1a, supporting up to four monitors at 7680 x 4320 resolution. The 3.8-slot design measures 358 mm in length and requires an 850W power supply for stable operation.

Questions about this item

Will the PCI Express 5.0 x16 interface work in my older PCIe 4.0 motherboard slot?

Yes, the card is backward compatible and will run at PCIe 4.0 speeds in a 4.0 slot without any configuration needed.

How can I verify the 2790 MHz OC mode core clock is active after installation?

Open GPU-Z or the ASUS GPU Tweak III utility and check the sensor tab; the boost clock should read 2790 MHz when the OC profile is selected and the card is under load.

Does the box include a power adapter for the 16-Pin connector or must I buy one separately?

The package contains a 16-Pin to dual 8-pin adapter cable; you only need a power supply with two free 8-pin PCIe cables or a native 12VHPWR output.
