Release year	2025	2024
Processor	Intel Core Ultra 9 285H; 16 cores, 16 threads; 2.9 GHz base, up to 5.4 GHz; 24 MB cache The processor’s Intel AI Boost NPU delivers up to 13 TOPS of AI processing; some Windows AI features use this unit instead of the graphics card. ASUS	Intel Core i9-14900HX: 24 cores, 32 threads, 2.2 GHz base, up to 5.8 GHz, 36 MB cache ASUS
Graphics	NVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; ROG Boost 1647 MHz; 120 W (100 W + 20 W Dynamic Boost) 120 W is the upper power limit including Dynamic Boost: the extra 20 W is shifted to the GPU when the processor load is low and is not always available. The RTX 5070 Ti version of the same chassis is limited to 115 W, and the RTX 5060 and 5070 versions to 105 W. ASUS	NVIDIA GeForce RTX 4070 Laptop GPU, 8 GB GDDR6; ROG Boost 2225 MHz at 140 W (115 W + 25 W Dynamic Boost) 140 W is the top of NVIDIA’s allowed power range for the RTX 4070 Laptop GPU; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered to the board. ASUS
Graphics switching	MUX Switch and NVIDIA Advanced Optimus Advanced Optimus switches the internal display between the processor’s integrated graphics and the RTX 5090 without a restart. The MUX switch connects the display directly to the RTX 5090, removing the integrated graphics from the path in games. ASUS	—
Display	16-inch 2.5K (2560 × 1600) OLED, 16:10, 240 Hz; 100% DCI-P3; G-Sync; Pantone Validated 240 Hz shows up to 240 frames per second in games; G-Sync matches the display refresh rate to the graphics card’s frame rate to prevent tearing. Pantone Validated means the display colours are verified against Pantone reference colours. ASUS does not give brightness or response time on this page. ASUS	18-inch ROG Nebula, 2560 × 1600 (16:10), IPS-level, 240 Hz, 3 ms; 100% DCI-P3; G-Sync; Pantone Validated; anti-glare 240 Hz shows motion more smoothly and with less blur in fast games; G-Sync matches the refresh to the frame rate to reduce tearing.
