Mini LED backlighting dims and lights zones behind the LCD so dark areas look deeper in HDR. 240 Hz means motion at up to 240 frames per second in suitable games; G-Sync matches refresh to frame rate to reduce tearing. 100% DCI-P3 covers the cinema colour space.

Graphics8-core GPU; 10-core GPU option; hardware ray tracing

The 10-core GPU is a configure-to-order option; the base model has 8 cores.

Apple		NVIDIA GeForce RTX 4090 Laptop GPU, 16 GB GDDR6; 2090 MHz ROG Boost at 175 W (2040 MHz boost + 50 MHz OC; 150 W + 25 W Dynamic Boost)

175 W is the maximum GPU power when Dynamic Boost borrows budget from the CPU; the base sits at the top of NVIDIA’s 80–150 W range for this GPU. The laptop GPU is not the same product as the desktop RTX 4090.

ASUS
Memory16 GB; 24 / 32 GB options
