Release year20252024
ProcessorIntel Core Ultra 7 255HX; 20 cores (8 performance + 12 efficiency), 20 threads, up to 5.2 GHz, 30 MB Intel Smart Cache

The Intel AI Boost NPU, rated at up to 13 TOPS, is built into the processor.

Lenovo
Intel Core i9-14900HX: 24 cores (8 P + 16 E), 32 threads, 2.2 GHz, up to 5.8 GHz, 36 MB cache

P-cores handle games and single-threaded loads, E-cores take background and multi-core work.

ASUS
GraphicsNVIDIA GeForce RTX 5050 Laptop GPU, 8 GB GDDR7; 2662 MHz boost, 115 W TGP, 440 AI TOPS

115 W TGP is among the higher power limits used for this GPU in laptops; the same RTX 5050 runs at lower power in thinner chassis. The graphics chip is soldered. Lenovo also offers the RTX 5060 and 5070 Laptop GPU in this chassis at 115 W.

Lenovo
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
Display15.1-inch WQXGA (2560 × 1600) OLED; 165 Hz, 500 nits typical / 1000 nits peak, 100% DCI-P3, glossy surface, DisplayHDR True Black 600, Dolby Vision

DisplayHDR True Black 600 is the VESA tier verifying 600-nit peak brightness and very low black level on OLED panels. The panel is factory colour-calibrated and TÜV-certified for low blue light and flicker-free operation; it is not a touchscreen. The platform sheet does not list G-SYNC for this panel.

Lenovo
18-inch ROG Nebula HDR, 2560 × 1600 (16:10) Mini LED; 240 Hz, 3 ms; 100% DCI-P3; anti-glare; G-Sync; Pantone Validated

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.

ASUS
Memory16 GB (1 × 16 GB) DDR5-5600 SO-DIMM; 2 slots, dual-channel capable

With one module fitted at the factory, memory runs in single channel; adding a matching module to the free slot enables dual channel. The highest capacity Lenovo has tested is 32 GB.

Lenovo
2 × 32 GB DDR5-5600 SO-DIMM (64 GB), dual channel; up to 64 GB

Both slots are populated; the modules are not soldered. ASUS notes memory speed can vary with the CPU.

ASUS
Storage1 TB M.2 2242 PCIe 4.0 x4 NVMe SSD; 2 × M.2 2280 PCIe 4.0 x4 slots

A second SSD can be fitted in the free M.2 slot.

Lenovo
2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD (RAID 0); two M.2 PCIe slots (both used)

RAID 0 joins the two SSDs into one drive for speed and capacity; if one SSD fails, all data in the array can be lost. ASUS says only single-sided SSDs are supported because of components near the M.2 slot.

ASUS
Ports1 × Thunderbolt 4 / USB4 40 Gbps USB-C (DisplayPort 2.1), 1 × USB-C 10 Gbps (USB PD 95–100 W, DisplayPort 2.1), 3 × USB-A 5 Gbps (one always on), 1 × HDMI 2.1 (up to 8K 60 Hz), 1 × RJ-45 gigabit Ethernet, 3.5 mm headset jack, slim-tip power input

USB-C charging works only through the 10 Gbps port; the Thunderbolt 4 port does not accept power. Up to 3 external displays are supported alongside the built-in panel: HDMI up to 8K 60 Hz, USB-C up to 5K 60 Hz. There is no SD card reader.

Lenovo
1 × Thunderbolt 4 (40 Gbit/s, DisplayPort / G-SYNC), 1 × USB 3.2 Gen 2 Type-C (10 Gbit/s, DisplayPort / power delivery / G-SYNC), 2 × USB 3.2 Gen 2 Type-A (10 Gbit/s), 1 × HDMI 2.1 FRL, 1 × 2.5G LAN, 3.5 mm audio

Thunderbolt 4 can also connect an external GPU enclosure or dock. The RJ45 port does not support Power over Ethernet, only data.

ASUS
WirelessWi-Fi 7 (802.11be) 2 × 2, Bluetooth 5.4 LenovoWi-Fi 6E (802.11ax) triple band 2×2, Bluetooth 5.2

Wi-Fi 6E can use the less congested 6 GHz band with a suitable router; ASUS notes the band may be unavailable in some countries.

ASUS
Battery and power80 Wh lithium-ion; 245 W slim-tip adapter, Super Rapid Charge

Lenovo rates battery life at 4.4 hours in MobileMark 30 and 10.8 hours in local 1080p video playback. Super Rapid Charge goes from 0 to 30% in 10 minutes and to 70% in 30 minutes; the battery must be at least 10 °C while charging.

Lenovo
90 Wh, 4-cell lithium-ion; 330 W AC adapter (20 V, 16.5 A, ø6.0 mm) and 100 W USB-C adapter

Full performance needs the 330 W adapter; the 100 W USB-C adapter is for light use and charging on the go. ASUS says the battery can reach 50% in 30 minutes with the proper adapter while the laptop is shut down. Bundled adapters can vary by country.
