ProcessorIntel 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 Ultra 9 275HX; 24 cores (8 P + 16 E), 24 threads, up to 5.4 GHz, 36 MB cache

Intel lists 55 W base and 160 W maximum turbo power for this chip; actual power in the laptop depends on HP's tuning and cooling.

HP
GraphicsNVIDIA 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 5080 Laptop GPU; 16 GB GDDR7; Advanced Optimus

This is the laptop RTX 5080, not the desktop card. HP's product sheet does not give the GPU power limit (TGP) for this SKU. Advanced Optimus switches the display between integrated and discrete GPU without a reboot.

HP
Graphics switchingMUX 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.

Display16-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		16-inch WQXGA 2560 × 1600, 16:10, IPS, anti-glare; 60–240 Hz, 3 ms

Games need high frame rates to benefit from 240 Hz; the panel follows variable frame rates with G-SYNC.
