What the card is and who it serves

The ASUS ROG ASTRAL MIKU C GeForce RTX 5080 is a graphics card built on the Blackwell architecture with 10752 CUDA cores. It carries 16GB of GDDR7 memory on a 256-bit bus running at 30 Gbps. The PCI Express 5.0 x16 interface delivers full bandwidth to modern platforms. It targets creators and enthusiasts who need high frame rates at 4K and 8K resolutions.

Connectors and day-to-day use

Two HDMI 2.1b ports and three DisplayPort 2.1a outputs drive up to four displays simultaneously at 7680 x 4320. The mix lets you attach high-refresh monitors, VR headsets or a TV without adapters. DLSS 4.0 upscaling is supported in compatible titles. DirectX 12 Ultimate and OpenGL 4.6 cover current rendering workloads.

Upgrade context and when it matters

Moving from a card with less VRAM or an older memory type gains headroom for 4K textures and large creative projects. The 16GB GDDR7 buffer and 256-bit bus reduce bottlenecks in memory-heavy scenes. If your current GPU limits resolution, refresh rate or multi-monitor layouts, this step up removes those constraints.

Questions sur cet article

What bandwidth ceiling does the PCI Express 5.0 x16 interface impose on this card?

The PCI Express 5.0 x16 link provides the electrical pathway for the RTX 5080 GPU and its 16GB GDDR7 memory running at 30 Gbps across a 256-Bit bus.

What physical space and power connectors does the ROG ASTRAL MIKU C need inside the case?

The card occupies a triple-slot footprint and draws auxiliary power through a 12VHPWR connector; verify case clearance and PSU cable reach before ordering.

Which driver step do builders often skip when installing this RTX 5080?

After seating the card and attaching the 12VHPWR cable, install the latest NVIDIA Game Ready driver before launching any title so DLSS 4.0 and the 10752 CUDA cores are recognised.
