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 i7-13650HX; 14 cores (6 P + 8 E), 20 threads, up to 4.9 GHz

HX processors are high-power mobile chips; sustained power and fan noise depend on Lenovo’s power modes.

Lenovo
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 4060 Laptop GPU; 8 GB GDDR6; 115 W TGP with the 230 W adapter, 105 W with the 170 W adapter

TGP is the sustained power limit given to the GPU; on the same GPU a higher TGP usually means higher gaming performance. Lenovo ties TGP on this platform to the wattage of the bundled adapter.

Lenovo
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		15.6-inch FHD (1920 × 1080) IPS, 144 Hz, 300 nits, 100% sRGB, anti-glare; NVIDIA G-SYNC

144 Hz shows smooth motion up to 144 frames per second in games; G-SYNC matches the refresh to the GPU’s frame rate to reduce tearing.

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

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

ASUS		—
Memory64 GB LPDDR5X-7467, soldered on board, dual channel; no memory slot

Memory cannot be upgraded later; the capacity chosen at purchase is permanent.

ASUS		24 GB DDR5-4800 (2 × 12 GB SODIMM); two slots, up to 32 GB

Memory is not soldered; both slots come filled, so an upgrade means replacing both modules. The 32 GB limit is Lenovo’s platform statement.

Lenovo
Storage2 TB M.2 NVMe PCIe 4.0 SSD; 2 × M.2 PCIe slots in total

The second M.2 slot allows an extra SSD. ASUS gives no separate PCIe generation for the free slot.

ASUS		1 TB M.2 2242 PCIe 4.0 NVMe QLC SSD; two M.2 PCIe 4.0 x4 slots

The second M.2 slot allows an extra SSD. QLC flash can slow down sooner than TLC during long, large writes.

Lenovo
Ports1 × Thunderbolt 4 (40 Gbps, DisplayPort, power input); 1 × USB-C 10 Gbps (DisplayPort, power input, G-SYNC); 2 × USB-A 10 Gbps; HDMI 2.1 FRL; UHS-II SD card reader (312 MB/s); 3.5 mm audio

Both USB-C ports support an external display and charging; the 10 Gbps USB-C port also carries G-SYNC to an external display. ASUS does not state the USB-C charging power.

ASUS		1 × USB-C 10 Gbps (USB PD 65–100 W input, DisplayPort 1.4); 3 × USB-A 5 Gbps; HDMI 2.1; RJ-45 gigabit Ethernet; 3.5 mm headphone/mic

Charging over USB-C works, but 140 W input needs Lenovo’s own adapter; the slim-tip port remains the main power input for gaming. There is no Thunderbolt or USB4.

ASUS’s Middle East page also lists a 100 W USB-C adapter in the box and notes that the adapter can vary by region and model.

ASUS		60 Wh lithium-ion; up to 50% in 30 minutes with Rapid Charge Pro; 170 W or 230 W slim-tip adapter

Lenovo rates it at 4.1 hours in MobileMark 25 and 5.6 hours of local 1080p video at 150 nits.

Lenovo
