What the card is

The ASUS PRIME GeForce RTX 5080 16GB GDDR7 is a graphics card built on the NVIDIA Blackwell architecture. It carries 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit bus running at 30 Gbps. The board connects through a PCI Express 5.0 x16 slot and drives up to four displays via one HDMI 2.1b and three DisplayPort 2.1a outputs. Maximum digital resolution reaches 7680 x 4320.

What to verify before ordering

Confirm that your motherboard provides a PCI Express 5.0 x16 slot and that your power supply can meet the card’s requirements with the correct connectors. Ensure the chassis has enough length and height clearance for a dual-slot design. Check that your monitor cables match HDMI 2.1b or DisplayPort 2.1a to use the full feature set. Verify the operating system supports DirectX 12 Ultimate and the latest NVIDIA drivers.

Who this suits and who should look elsewhere

This model suits 4K gamers and content creators who want 16GB of high-speed GDDR7 memory and DLSS 4.0 support for modern titles and GPU-accelerated workloads. Users building compact small-form-factor systems or running older power supplies with limited wattage should consider a lower-power alternative. Buyers needing more than four simultaneous displays or specialised workstation certifications should evaluate professional-series cards instead.

Questions about this item

What comes in the box with the ASUS PRIME GeForce RTX 5080 and do I need to buy any cables or adapters separately?

The card includes one HDMI 2.1b port and three DisplayPort 2.1a outputs for up to four monitors. Use your existing cables or purchase the specific HDMI or DisplayPort cables you need for your displays.

Which version of the ASUS PRIME RTX 5080 should I choose for 4K gaming and heavy workloads?

This model provides 16GB of GDDR7 memory on a 256-bit bus with an effective 30 Gbps clock. That single configuration is built for high-resolution gaming and compute tasks that benefit from the 10752 CUDA cores.

What does the 30 Gbps memory speed on the RTX 5080 actually deliver inside my PC?

The 30 Gbps effective clock on the 256-bit GDDR7 interface moves data to the 10752 CUDA cores over the PCI Express 5.0 x16 link, supporting the 7680 x 4320 maximum resolution and DLSS 4.0 features.
