Paired with the NVIDIA GeForce RTX 5070 Ti GPU, featuring 12GB GDDR7 and NVIDIA’s latest Ada Lovelace architecture, it supports DLSS 4, ray tracing, and high frame rates, ensuring smooth performance in titles like Black Myth: Wukong, Cyberpunk 2077, and Starfield.
Benchmark highlights include:
- Geekbench 6: The Ultra 9 275HX delivers top-tier multi-core scores, surpassing previous-gen Intel i9-13980HX, ideal for multitasking and AI-accelerated tasks.
- 3DMark Time Spy: The RTX 5070 Ti performs comparably to the RTX 4090 in efficiency, achieving 80+ FPS at 2.5K in most AAA games with DLSS enabled.

Gaming Performance
The 240Hz 2.5K Mini LED display with G-SYNC ensures ultra-smooth visuals, eliminating tearing in fast-paced games like Valorant (150+ FPS at 2.5K) and DOOM Eternal (100+ FPS at ultra settings). The MUX Switch with Advanced Optimus boosts performance by 5–10% by routing frames directly from the GPU, optimizing both power efficiency and frame rates. While the native 2.5K resolution is stunning, the laptop’s Thunderbolt 5 (120Gbps) and HDMI 2.1 FRL ports make it a powerhouse for 4K external displays, perfect for immersive gaming setups.
Multitasking and Productivity
With 32GB DDR5-5600MHz RAM, the Scar 18 handles multitasking effortlessly, supporting game streaming, video editing in Adobe Premiere, and 3D modeling in Blender. The 1TB PCIe Gen 4 SSD offers lightning-fast load times (up to 7,000MB/s), and the second M.2 slot allows for easy upgrades to 4TB, ideal for large game libraries and creative projects. The Intel AI Boost NPU enhances AI-driven tasks, such as real-time video upscaling or AI content creation, making it a versatile choice for creators.
Display: Stunning Visuals, Not Native 4K
The 18” ROG Nebula HDR display is a highlight, featuring Mini LED technology with over 2,000 dimming zones, 1200 nits peak brightness, and 100% DCI-P3 color coverage. The 240Hz refresh rate and 3ms response time deliver fluid visuals, while dual ACR layers reduce reflections and boost contrast by 4.5x, ensuring vibrant colors even in bright environments. The 16:10 aspect ratio provides extra vertical space, ideal for gaming and productivity.
However, the display is 2.5K (2560 x 1600), not native 4K, which may disappoint users expecting ultra-high resolution on the laptop itself. For 4K gaming, an external monitor is required, but the laptop’s robust ports make this seamless. Compared to OLED panels, the Mini LED offers superior brightness and HDR performance, though some reviews note minor blooming in high-contrast scenes. For gamers prioritizing refresh rate and color accuracy, this display is among the best for gaming laptops in 2025.
Cooling: Best-in-Class Thermal Performance
The ASUS ROG Strix Scar 18 excels in thermal management, making it a top choice for the best cooling gaming laptop in 2025. The ROG Intelligent Cooling system includes:
- End-to-end vapor chamber for efficient heat dissipation.
- Tri-Fan technology with 84-blade fans for maximum airflow.
- Conductonaut Extreme liquid metal on CPU and GPU, reducing temperatures by up to 15°C compared to traditional thermal paste.
- Full-surround vents and dust filters to maintain long-term performance.
During stress tests, the CPU stays below 90°C and the GPU below 80°C, even in Turbo Mode (55W CPU, 140W GPU). The fans, while audible, remain quieter than competitors like the MSI Raider 18 HX, and the keyboard deck stays comfortable during extended sessions. This cooling prowess ensures sustained performance without throttling, critical for marathon gaming or rendering tasks.
Design and Build Quality
Weighing 6.83 lbs and measuring 30.9mm thick, the Scar 18 is hefty but justified by its 18” display and high-end components. The matte black chassis feels premium, replacing the translucent plastic of older models for a sleek, professional look. The per-key RGB keyboard offers customizable lighting, and the AniMe Vision lid displays animations or text for personalization. The tool-less bottom panel simplifies upgrades for RAM, SSD, and fans, a rare feature in gaming laptops.
The sturdy hinge and MIL-STD-810H durability ensure reliability, though the size may not suit frequent travelers. The trackpad is responsive but average for productivity, and the 720p webcam and microphone are underwhelming for streaming or calls, requiring external peripherals for content creators.
Connectivity and Ports
The Scar 18 is future-proofed with:
- 2x Thunderbolt 5 (120Gbps, DisplayPort, power delivery, G-SYNC)
- 1x HDMI 2.1 FRL
- 3x USB 3.2 Gen 2 Type-A (10Gbps)
- 1x 2.5G LAN port
- 1x 3.5mm combo audio jack
- Wi-Fi 7 and Bluetooth 5.4 for ultra-fast wireless connectivity
The Wi-Fi 7 ensures low-latency online gaming, and Thunderbolt 5 supports high-speed peripherals and external GPUs, making it ideal for advanced setups. The side-loaded ports, while not as tidy as rear-mounted ones, are well-placed for accessibility.
Battery Life
The 90Wh battery provides up to 6 hours of light use (web browsing, streaming at 150 nits), but gaming reduces this to 1–2 hours due to the power-hungry RTX 5070 Ti. Thunderbolt 5 power delivery (up to 100W) offers charging flexibility, but the 280W AC adapter is recommended for peak performance. Battery life is typical for high-end gaming laptops, prioritizing power over longevity.
