Release year20242023
ProcessorIntel Core i9-14900HX: 24 cores (8 P + 16 E), 32 threads; P-core 2.2/5.8 GHz, E-core 1.6/4.1 GHz; 36 MB Intel Smart Cache; Intel HM770 chipset LenovoAMD Ryzen 9 7940HS; 8 cores / 16 threads; up to 5.2 GHz; 16 MB L3 cache

The chip also includes Radeon 780M integrated graphics.

ASUS
GraphicsNVIDIA GeForce RTX 4080 Laptop GPU, 12 GB GDDR6; 2280 MHz boost clock, 175 W TGP, 542 AI TOPS

175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

Lenovo		NVIDIA GeForce RTX 4060 Laptop GPU; 8 GB GDDR6; ROG Boost 2300 MHz; 125 W (100 W + 25 W Dynamic Boost)

2300 MHz is the 2250 MHz boost clock plus a 50 MHz ASUS overclock; ASUS says it measured this with FurMark in a 25 °C lab. The graphics chip is soldered and cannot be upgraded.

ASUS
Display16-inch WQXGA (2560 × 1600) IPS, non-touch, 500 nits, anti-glare, 16:10, 1200:1, 100% DCI-P3, 240 Hz; DisplayHDR 400, Dolby Vision, G-SYNC, X-Rite factory calibration

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

Lenovo		14-inch QHD+ (2560 × 1600, 16:10); IPS-level, anti-glare; 165 Hz; 3 ms; DCI-P3 100%; Pantone Validated

DCI-P3 100% covers the cinema colour space; Pantone Validated means colour accuracy was checked at the factory. This SKU does not have the mini LED Nebula HDR display.

ASUS
Memory1 × 16 GB DDR5-5600 SO-DIMM; two slots, dual-channel capable; up to 32 GB in Lenovo’s offering

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

Lenovo		16 GB DDR5 (soldered on board); 1 × DDR5 SO-DIMM slot; up to 32 GB

Memory can be increased by fitting a module in the SO-DIMM slot alongside the soldered memory.

ASUS
Storage2 × 1 TB M.2 2280 PCIe 4.0 x4 NVMe SSD; two M.2 2280 PCIe 4.0 x4 slots (both used)

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

Lenovo		512 GB PCIe 4.0 NVMe M.2 SSD; 1 × M.2 slot

With a single M.2 slot, capacity is increased by replacing the SSD with a larger one.

ASUS
Ports1 × Thunderbolt 4 / USB4 40 Gbit/s (DisplayPort 1.4), 1 × USB-C 10 Gbit/s (Lenovo PD 140 W, DisplayPort 1.4), 4 × USB-A 5 Gbit/s (one Always On), 1 × HDMI 2.1 (up to 8K/60 Hz), 1 × RJ45 Gigabit Ethernet, 3.5 mm audio

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

Lenovo		1 × USB4 Type-C (DisplayPort, power delivery, 40 Gbit/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); 3.5 mm audio jack

There is no Ethernet port.

CoolingHybrid cooling: air cooling + liquid-metal thermal interface

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.

Battery and power99.9 Wh lithium-ion, Super Rapid Charge; 330 W slim-tip GaN adapter

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.

Lenovo		76 Wh, 4-cell lithium-ion; 240 W adapter (ø6.0 mm)

It can also charge over USB-C through the USB4 port; full performance needs the 240 W adapter.
