Highlights

• Quad-Fan Cooling: First ROG card with a quad-fan design — three 105mm Axial-tech fans on the front and a dedicated rear fan — delivering up to 20% more airflow and pressure for sustained peak performance
• Factory Overclocked to 2760 MHz (2790 MHz OC Mode): Significantly higher boost clocks than the reference RTX 5080 (2550 MHz), with a dual-BIOS switch for Performance and Quiet modes
• NVIDIA Blackwell Architecture: Powered by the GB203 chip with 10,752 CUDA Cores, 5th-Gen Tensor Cores, 4th-Gen Ray Tracing Cores, and DLSS 4 support for next-level AI-accelerated gaming
• Advanced Thermal Engineering: Patented vapor chamber with milled pathways, MaxContact mirror-finished heat spreader, phase-change GPU thermal pad, and ultra-dense fin stack for exceptional heat dissipation
• Premium Power & Build Quality: 50-amp MOSFETs provide 25% more power headroom, a protective PCB coating guards against moisture and dust, and an ultra-rigid die-cast frame ensures long-term durability

Description

The ROG Astral GeForce RTX™ 5080 16GB GDDR7 OC Edition is ASUS's flagship RTX 5080 graphics card, built for enthusiasts who demand the absolute best. Based on NVIDIA's Blackwell GB203 silicon, it features 10,752 CUDA Cores and 16GB of high-speed GDDR7 memory on a 256-bit bus, delivering 960 GB/s of memory bandwidth. Factory overclocked to 2760 MHz in default mode and up to 2790 MHz in OC mode, it significantly surpasses reference clock speeds. The first ROG card to feature a quad-fan cooling design, combined with a vapour chamber, MaxContact heat spreader, and phase-change thermal pad, it maintains stable thermals even under the most demanding workloads. With DLSS 4 support, PCIe 5.0 connectivity, and ROG's renowned build quality including 50-amp MOSFETs and a protective PCB coating, the ROG Astral RTX 5080 OC Edition is the definitive high-performance GPU for 4K gaming and content creation.
