ASUS Prime GeForce RTX 5080 OC 16GB Graphics Card: features and specs

The ASUS Prime GeForce RTX 5080 OC Edition is a graphics card built around NVIDIA's Blackwell architecture, with 16GB of GDDR7 memory. ASUS markets it as "SFF-Ready", meaning it is designed to fit smaller cases than many cards in this class. Here is what its main specifications mean.

The GPU and memory

The card uses the GeForce RTX 5080 graphics processor from NVIDIA's Blackwell generation and supports DLSS 4, NVIDIA's AI-based upscaling and frame-generation technology. DLSS renders a game at a lower internal resolution and uses AI to reconstruct the image, which can raise frame rates in supported titles.

The card carries 16GB of GDDR7 memory. Video memory holds textures and frame data, so a larger amount typically helps at high resolutions and with high-detail textures. "OC Edition" means ASUS has factory-overclocked the card compared with NVIDIA's reference clock speeds; the exact clocks aren't given in the listing.

PCIe 5.0 and display outputs

The card connects through PCIe 5.0, the latest generation of the slot standard. It is backward compatible, so it works in PCIe 4.0 and 3.0 slots, although the available bandwidth is then lower. Outputs include HDMI 2.1 and DisplayPort 2.1, which are the connections needed for high-resolution, high-refresh-rate monitors and modern televisions.

Cooling design

ASUS describes three Axial-tech fans, each with a smaller hub that allows longer blades, plus a barrier ring that increases downward air pressure. The shroud, heatsink and heat pipes are arranged so the fans can draw on air from the side-panel ventilation of the case. A vapor chamber, a flat sealed plate that spreads heat quickly, sits against the GPU, and a phase-change thermal pad is used between the chip and the cooler. ASUS says the pad provides better thermal conductivity than a conventional pad and helps with long-term reliability. The card also has a Dual BIOS switch.

Built for compact cases

At 2.5 slots, 12.0 x 5.0 x 2.0 inches (about 30.5 x 12.7 x 5.1 cm) and 2.9 lb (about 1.3 kg), the card is relatively compact for its class. That helps in small-form-factor systems, though it still needs space for length, thickness and airflow.

Who it suits

It suits PC builders who want a high-end GeForce card in a smaller case, and gamers who play at high resolutions or want DLSS 4 support. It also suits creators who use GPU-accelerated applications. It is more than most office or basic gaming PCs require.

What to check before you buy

• Case clearance: check the length (about 12 inches), the 2.5-slot thickness and the room around it in your case.
• Power supply: high-end cards need a capable power supply and the correct power connector. Check NVIDIA's and ASUS's published requirements for this model.
• Airflow: vented side panels and good fan placement help the cooler work as designed.
• Motherboard slot: it works in older PCIe slots, but confirm you have a free x16 slot.
• Monitor ports: make sure your display uses HDMI or DisplayPort.
• Weight and support: consider a support bracket if your case is mounted upright or moved often.
