This article covers ASUS TUF-RTX5080 16GB GDDR7 ゲーム向けグラフィック.

Overview

The ASUS TUF-RTX5080-O16G-GAMING is a custom-designed graphics card built around NVIDIA's Blackwell GeForce RTX 5080 GPU. With 16GB of GDDR7 memory and a PCI Express 5.0 interface, it delivers the horsepower needed for high-refresh-rate 4K gaming and creative workloads. ASUS leverages its MaxContact design to increase GPU heat-spreader surface area by 5%, combined with a large vapor chamber and three Axial-tech fans (dual ball bearings) that push 23% more airflow than standard fans. The phase-change GPU thermal pad melts under load to fill micro-gaps, ensuring consistent thermal transfer over years of use. This card can handle a 360W TDP without thermal throttling — a solid choice for those who value stability. In the GPU market, the TUF-RTX5080 sits in the upper mid-range to high-end tier. It competes directly with MSI and Gigabyte variants, but ASUS differentiates itself with military-grade durability and an emphasis on long-term reliability.

Compatibility Guide

PCI Express 5.0 x16 slot required for full bandwidth, though PCIe 4.0/3.0 slots work with minor performance loss. Ports include 2× HDMI 2.1b and 3× DisplayPort 2.1b, supporting up to four simultaneous displays at 8K resolution. Recommended PSU: 850W or higher (360W TDP + transient spikes). Requires a 12V-2x6 (12VHPWR) connector — ensure your PSU includes one or use the included adapter. Physical dimensions: 348×146×72mm (3.6 slots). Verify your case's maximum GPU length and slot clearance before purchase. * The GPU packs 10,752 CUDA cores (84 SMs), 84 RT cores, and 336 Tensor cores. Full Blackwell feature set, including DLSS 4 frame generation.

Product Info

Released on January 30, 2025, the ASUS TUF-RTX5080 is widely available through official retailers and authorized distributors. Market positioning: upper mid-range to high-end. It targets gamers and creators who want robust cooling and all-around durability without crossing into flagship RTX 5090 territory. GPU Clock: Boost up to 2730 MHz (factory OC) Memory: 16GB GDDR7, 256-bit bus, 960 GB/s bandwidth TDP: 360W Warranty: 3 years (requires product registration) * Slot occupancy 3.6 slots

Best Use Cases

Enthusiasts targeting 4K 144 Hz gaming — The RTX 5080 delivers 56.28 TFLOPS FP32, enough for maxed-out settings in most titles at 4K. The TUF cooling ensures sustained performance during long sessions. However, if you mainly play at 1440p, the RTX 5070 Ti offers better value. Video editors and 3D artists requiring 16GB VRAM — DaVinci Resolve, Blender, and Premiere Pro benefit from the 16GB GDDR7 buffer for 4K timelines and moderate 3D scenes. Not ideal for 8K workflows or large VFX. * Users who prioritize reliability over silence — The TUF's aggressive fan curve keeps temperatures low, but it's not silent under load. If absolute quiet is needed, consider a water-cooled card like the ASUS ROG Strix LC. ## Alternatives
Direct competitors include the MSI GeForce RTX 5080 GAMING TRIO and the GIGABYTE GeForce RTX 5080 GAMING OC. The MSI offers comparable cooling with Torx fans, while Gigabyte slightly undercuts on size but has fewer premium thermal features. ASUS stands out with its military-grade build, phase-change pad, and generally better after-sales support. All three share the same GPU core and 16GB GDDR7 — choice often comes down to cooling philosophy, fit in your case, and price.

Things to Consider

The TUF-RTX5080's size is the biggest hurdle — at 348mm length and 3.6 slots, it will not fit in many mATX or ITX cases. Measure your case's GPU clearance first. The 12V-2x6 power connector requires an ATX 3.0/3.1 PSU; if your existing PSU is older, factor in a PSU upgrade. 360W TDP means substantial heat output. Your case needs good airflow — at least two intake fans and one exhaust. If your build is focused on low power consumption or small form factor, this card is overkill. Consider the RTX 4070 Ti SUPER for 1440p gaming with much lower power draw. ## FAQ Q: How does this compare to the RTX 4080 SUPER? A: The RTX 5080 delivers roughly 30-40% higher performance in ray-traced scenarios thanks to Blackwell's architectural improvements and faster GDDR7 memory. Raw raster gains are ~20% on average. Q: Can it handle VR? A: Yes, with DisplayPort 2.1b it can drive high-resolution headsets like the Pimax Crystal at native resolution. No adapters needed for most modern VR systems. Q: Do I need to register for the 3-year warranty? A: Yes, register within 60 days of purchase on ASUS's site. Without registration, the default warranty is 1 year.
