ASUS NOCTUA RTX 5080 16GB GDDR7

This graphics card pairs the NVIDIA GeForce RTX 5080 GPU with a Noctua cooling collaboration. It delivers 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit bus running at 30 Gbps. The board connects via PCI Express 5.0 x16 and supports DirectX 12 Ultimate and OpenGL 4.6.

4K gamers and creators needing DLSS 4.0

The card suits enthusiasts targeting 7680 x 4320 resolution across up to four displays using two HDMI 2.1b and three DisplayPort 2.1a outputs. DLSS 4.0 and the Blackwell architecture accelerate modern titles and creative workloads. Users requiring more than 16GB of frame buffer or multi-GPU scaling should consider alternative models.

16GB GDDR7 frame buffer decides fit

The 16GB GDDR7 memory capacity is the single specification that determines whether this model matches a workload. It provides high bandwidth at 30 Gbps for 4K gaming and many content-creation tasks. Projects that regularly exceed this VRAM limit will need a card with a larger memory allocation.

Questions about this item

How many expansion slots does the ASUS NOCTUA RTX 5080 occupy in a chassis?

The card uses a dual-slot design that fits standard ATX cases with two free rear brackets and a PCI Express 5.0 x16 motherboard slot.

Which power connectors must be attached during installation, and which step do builders often skip?

Connect the single 12V-2x6 cable fully until it clicks; the common mistake is leaving it partially seated, which causes instability under load.

How should the Noctua fans and heatsink be cleaned to maintain cooling performance over time?

Use compressed air to blow dust from the fin stack and fan blades every few months; avoid liquids and do not disassemble the cooler.
