ASUS Astral GeForce ROG RTX 5080 16GB GDDR7 256-Bit Gaming Graphics Card

ASUS ROG Astral RTX™ 5080 OC 16GB GDDR7: Space-Age Power, Silence, and Style

The ROG Astral RTX 5080 OC redefines high-end graphics cards with cutting-edge design, elite performance, and whisper-quiet operation wrapped in a futuristic chassis. Built for gamers, content creators, streamers, 3D artists, and productivity pros, this GPU delivers flagship-level visuals and responsiveness without the bulk, perfect for next-gen setups and SFF builds alike.

Next-Level Overclocking Meets High-Efficiency Airflow

ASUS equips the Astral with its highest factory overclock: boost clocks reaching up to 2760 MHz, far above the standard 2617 MHz reference. That translates to blistering performance in both 1440p and 4K gaming environments. TechPowerUp and TweakTown confirm double-digit FPS gains over other RTX 5080 cards, especially in 4K scenarios.

Thermally, it’s a marvel. The Quad-Fan Force setup, three front fans plus a rear-mounted pull fan, boosts airflow and static pressure by up to 20%, keeping cooling fans ultra-quiet even under sustained load. A patented vapor chamber further enhances heat dissipation, and massive all-metal shrouding and coating safeguard against dust and moisture. 

Flagship Power: 16GB GDDR7 + 10752 CUDA Cores

This GPU’s 16 GB of GDDR7 memory (30 Gbps, 256‑bit) supports ultra-detailed textures and 4K editing workflows, backed by a powerhouse of 10752 CUDA cores with Blackwell architecture, featuring 4th-gen RT and 5th-gen Tensor cores for cinematic ray tracing, DLSS 4, Reflex 2, and AI-driven workloads.

Silence Meets Strength: Quiet and Rigid

Despite its raw performance, the Astral remains surprisingly silent. Best Buy reviewers note fans remain inactive until temperatures exceed 50 °C and barely whisper even then. Overclock3D explains that the rear fan pulls air through the heatsink, boosting thermal efficiency while reducing noise. Temperatures remain around 62 °C under stress with room for user-defined overclocking.

Immersive Multi-Display Brilliance

You get three DisplayPort 2.1b and two HDMI 2.1b outputs, supporting up to four high-resolution monitors with NVIDIA G‑SYNC for tear-free visuals, ideal for streamers, multi-window professionals, gamers, or traders.

Compact Yet Commanding

Despite being one of the largest and heaviest GPUs available, it's intelligently engineered to control airflow and maintain quiet operation. It uses a single 16‑pin PCIe 5.0 connector, supports PCIe 5.0 buses, and draws 360 W, requiring a robust 750 W PSU.

The ASUS ROG Astral RTX 5080 OC is a statement piece, combining exceptional performance, whisper-quiet cooling, immersive display support, and a sleek outer shell, all at the cost of exclusivity. If your priority is top-tier 4K gaming, heavy creative workloads, and noise-free productivity, and you’ve got the build space and budget, the Astral delivers like nothing else.
