ASUS ROG Zephyrus G16 (2025) GU605CX / ASUS ROG Zephyrus G16 (2024) GU605MI-QR194X

ASUS ROG Zephyrus G16 (2025) GU605CX: GU605CX: the RTX 5090 Laptop GPU version; the GU605CX-QR111W and GU605CX-XS98 listed by ASUS come with 64 GB of memory and a 2 TB SSD. In the US, the GU605CX-G16.U9X5090 sold by Best Buy is listed with 32 GB. The same chassis is also sold with the RTX 5060/5070/5070 Ti/5080.

ASUS ROG Zephyrus G16 (2024) GU605MI-QR194X: GU605MI-QR194X: Core Ultra 9 185H, RTX 4070 Laptop GPU 8 GB (105 W = 85 W + 20 W Dynamic Boost), 32 GB LPDDR5X, 2 TB SSD, 240 Hz OLED, Windows 11 Pro; Platinum White in ASUS’s image. The GU605 series spans SKUs from the RTX 4050 to the 4090 and from the Core Ultra 7 155H to the Core Ultra 9 185H; not every GU605MI SKU has the same memory or display.

Release year20252024
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 185H: 16 cores, 22 threads, 2.3 GHz base, up to 5.1 GHz, 24 MB cache; Intel AI Boost NPU (up to 11 TOPS)

The NPU runs constant AI tasks such as background blur and noise suppression at low power instead of the CPU/GPU.

ASUS
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 4070 Laptop GPU, 8 GB GDDR6; ROG Boost 1655 MHz at 105 W (85 W + 20 W Dynamic Boost)

Dynamic Boost shifts a 20 W share of power to the GPU when CPU load is low, so 105 W is a conditional ceiling rather than a constant level. In the same series RTX 4060 SKUs are listed at 100 W and RTX 4080/4090 SKUs at 115 W. The GPU is soldered and cannot be upgraded.

ASUS
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 ROG Nebula OLED, 2560 × 1600 (16:10), 240 Hz, 0.2 ms; 100% DCI-P3; G-Sync; Pantone Validated; anti-glare low-reflection (AGLR) coating

G-Sync matches the refresh to the game’s frame rate to reduce tearing. It is not a touchscreen. Some SKUs in the same series use an IPS-level panel.

ASUS
Display surfaceAnti-glare, low-reflection coating (AGLR)

The coating is used to reduce reflections from lamps and windows in bright rooms.
