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, up to 5.8 GHz, 36 MB cache The HX series is Intel’s high-power family that brings near-desktop core counts to laptops. 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 4080 Laptop GPU, 12 GB GDDR6; ROG Boost 2330 MHz at 175 W (150 W + 25 W Dynamic Boost) ASUS adds a 50 MHz overclock to the 2280 MHz boost clock. Dynamic Boost shifts 25 W from the CPU to the GPU depending on load. The GPU is soldered and cannot be replaced. 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	—
