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
AMD Ryzen 9 8945HS (8 cores / 16 threads, 4.0 GHz, up to 5.2 GHz, 24 MB cache, 16 TOPS XDNA NPU)

24 MB is 8 MB of L2 plus 16 MB of L3 cache. The processor’s integrated Radeon 780M graphics handles light work when Advanced Optimus is active.

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 4070 Laptop GPU; 8 GB GDDR6; ROG Boost 1655 MHz; 90 W (65 W TGP + 25 W Dynamic Boost)

1655 MHz is the 1605 MHz boost clock plus a 50 MHz ASUS overclock. The 90 W ceiling is lower than RTX 4070 configurations in large 16–18-inch laptops and was chosen for the thin chassis. The GPU cannot be upgraded.

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
14-inch 3K OLED; 2880 × 1800 (16:10); 120 Hz; 0.2 ms; 100% DCI-P3; G-Sync and Adaptive-Sync; anti-glare low-reflection (AGLR) surface; Pantone Validated

Each OLED pixel makes its own light, so blacks are fully dark; leaving static images on screen for long periods raises the risk of image retention.

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
32 GB LPDDR5X-6400 on board; not expandable

Memory cannot be increased later, so the amount should be chosen at purchase.

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
1 TB PCIe 4.0 NVMe M.2 SSD; 1 × M.2 slot

There is a single M.2 slot, so more capacity means replacing the existing SSD with a larger one.

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 × USB4 Type-C (DisplayPort, Power Delivery, 40 Gb/s); 1 × USB 3.2 Gen 2 Type-C (DisplayPort); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; microSD (UHS-II) card reader; 3.5 mm combo audio jack

There is no wired Ethernet port; independent testing listed this and the lack of Wi-Fi 7 as drawbacks.

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
73 Wh 4-cell lithium-ion battery; 180 W adapter; plus a 100 W USB-C adapter

On battery the GPU runs at a lower limit; full performance needs the 180 W adapter.

This model has no IR camera or fingerprint reader, so Windows Hello biometric sign-in is not supported.
