Release year20242024
ProcessorIntel Core i9-14900HX; 24 cores (8 performance + 16 efficiency), 32 threads, up to 5.8 GHz, 36 MB cache

Intel lists 55 W base and 157 W maximum turbo power for this processor; the laptop’s actual limit is set by ASUS’s operating mode.

ASUS
Intel 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 Lenovo
GraphicsNVIDIA GeForce RTX 4080 Laptop GPU, 12 GB GDDR6; ROG Boost 2330 MHz at 175 W (150 W + 25 W Dynamic Boost)

NVIDIA gives a 60–150 W subsystem power range for this GPU; the 175 W figure includes the 25 W added by Dynamic Boost when CPU load is low. The graphics chip is soldered to the motherboard and cannot be replaced.

ASUS
NVIDIA 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
Display16-inch ROG Nebula HDR Mini LED; 2560 × 1600 (16:10), 240 Hz, 3 ms; DCI-P3 100%, anti-glare surface, G-SYNC, Pantone Validated

The Mini LED backlight dims in zones; Notebookcheck counted 2,048 dimming zones on its test unit. The display supports Dolby Vision HDR.

ASUS
16-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
Graphics switchingMUX Switch + NVIDIA Advanced Optimus

The MUX switch connects the internal display directly to the NVIDIA GPU to reduce latency in games; Advanced Optimus can make this switch without a restart.

Memory64 GB (2 × 32 GB) DDR5-5600 SO-DIMM; 2 slots, up to 64 GB

Both slots come filled in this configuration; upgrading memory means replacing the modules.

ASUS
1 × 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
Storage2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD (RAID 0); 2 × M.2 slots

RAID 0 combines the two drives into one volume; speed goes up, but if one drive fails all data can be lost.

ASUS
2 × 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
Ports1 × Thunderbolt 4 (DisplayPort, G-SYNC, 40 Gbps), 1 × USB 3.2 Gen 2 Type-C (DisplayPort, power delivery, G-SYNC), 2 × USB 3.2 Gen 2 Type-A, 1 × HDMI 2.1 FRL, 1 × 2.5G LAN, 1 × 3.5 mm audio jack

According to Notebookcheck the Thunderbolt 4 port does not accept charging; USB-C charging goes through the other Type-C port at up to 100 W. The LAN port does not support PoE, and there is no SD card reader.

ASUS
1 × 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.

Battery and power90 Wh, 4S1P, 4-cell lithium-ion; 330 W adapter (ø6.0 mm) and 100 W Type-C adapter

According to ASUS the battery reaches 50% in 30 minutes with fast charging. Full GPU power needs the 330 W adapter; the 100 W USB-C adapter is for light use and charging on the go.

ASUS
99.9 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.
