Performance Review
CPU Power & AI Optimization
The Core Ultra 9 275HX is Intel’s most advanced mobile processor to date, delivering desktop-class performance with 24 cores and 32 threads.
It dynamically distributes workloads between Performance (P) and Efficiency (E) cores while the AI Boost NPU intelligently allocates power for gaming, rendering, and streaming simultaneously.
In real-world tests, it achieves over 35,000 multi-core points in Cinebench R23, outperforming nearly all other 2025 laptops while maintaining impressive thermal consistency.
For creators, it accelerates AI tools like Adobe Firefly and DaVinci Resolve neural filters for real-time rendering and AI-enhanced workflows.
GPU & Gaming Performance
Armed with NVIDIA’s RTX 5080, the SCAR 18 delivers unmatched graphics performance for 4K and QHD+ gaming.
The Ada Lovelace architecture, paired with DLSS 3.5 Frame Generation and Ray Reconstruction, produces incredible fidelity and smoothness.
Performance examples at QHD+ (2560×1600):
- Cyberpunk 2077 (Overdrive Mode + DLSS 3.5) → 135–150 FPS
- Call of Duty Warzone 2 → 180 FPS Ultra
- Valorant / CS2 → 350 FPS+ Competitive Settings
- Alan Wake 2 / Starfield (QHD Ultra) → 110–120 FPS
Even at native 2.5K resolution, the RTX 5080 handles every modern title with ease, making this a true desktop-replacement for gamers and creators alike.
Display & Visual Experience
The ROG Nebula HDR 18-inch panel is a visual masterpiece. With 2,000+ local dimming zones, 1100 nits peak brightness, and Dolby Vision HDR, it produces deep contrasts and vibrant colors.
The 240 Hz refresh rate and 3 ms response time ensure buttery-smooth motion for competitive play, while Adaptive Sync eliminates tearing.
Whether you’re gaming, editing HDR footage, or streaming cinematic content, this display stands among the best ever fitted in a laptop.
Thermals & Cooling
ASUS’s ROG Intelligent Cooling combines liquid metal on the CPU and GPU, a large vapor chamber, and a tri-fan system with custom heatsinks.
The result: under sustained gaming, CPU temps remain around 80 °C and GPU temps near 75 °C — with minimal fan noise (~45 dB).
AI-driven thermal management dynamically adjusts airflow and power limits for silent operation when you’re not gaming.
Memory & Storage
With 32 GB DDR5-5600 MHz RAM, the SCAR 18 handles heavy multitasking, 4K video editing, and virtual machines flawlessly.
The 2 TB PCIe Gen 4 SSD delivers blazing speeds (over 7,000 MB/s read) for instant boot and near-zero load times in AAA titles.
Both RAM and storage are upgradeable — a rare bonus at this level of performance.

The SCAR 18’s aesthetic is pure ROG — bold, premium, and engineered for performance.
Its off-black metal chassis, translucent keyboard deck, and wraparound RGB light bar create a striking look under any lighting.
Despite its size, the laptop feels surprisingly solid yet manageable at 6.8 lbs, thanks to optimized weight distribution and durable materials.
The per-key RGB keyboard with deep key travel (2 mm) offers desktop-level responsiveness for competitive gaming.

The quad-speaker array with Dolby Atmos and Smart Amp technology produces rich, spatial sound for both gaming and media playback.
Connectivity options include:
- 2 × Thunderbolt 4 (USB-C with PD + DisplayPort)
