GraphicsNVIDIA GeForce RTX 4070 Laptop GPU, 8 GB GDDR6; ROG Boost 2225 MHz at 140 W (115 W + 25 W Dynamic Boost)

140 W is the top of NVIDIA’s allowed power range for the RTX 4070 Laptop GPU; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered to the board.

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
Display18-inch ROG Nebula, 2560 × 1600 (16:10), IPS-level, 240 Hz, 3 ms; 100% DCI-P3; G-Sync; Pantone Validated; anti-glare

240 Hz shows motion more smoothly and with less blur in fast games; G-Sync matches the refresh to the frame rate to reduce tearing.

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.

MUX and graphics switchingMUX Switch + NVIDIA Advanced Optimus

The MUX switch connects the display directly to the NVIDIA GPU; Advanced Optimus switches without a restart.

Memory32 GB (2 × 16 GB DDR5-5600 SO-DIMM); 2 SO-DIMM slots, dual channel

Because both slots are filled, upgrading means replacing the installed modules; memory speed depends on the processor’s support.

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 PCIe 4.0 NVMe M.2 SSD; 2 M.2 PCIe slots in total (including the one in use) ASUS2 × 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 (40 Gb/s, DisplayPort); 1 × USB 3.2 Gen 2 Type-C (DisplayPort, charging, G-SYNC); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; RJ45 LAN; 3.5 mm combo audio

USB-C charging is supported only on the USB 3.2 Gen 2 port; the Thunderbolt 4 port does not take charge. 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, 4-cell lithium-ion; 280 W adapter with round (ø6.0) plug; a 100 W USB-C adapter is also listed

Which adapter is in the box varies by country. Performance is limited when charging over USB-C.

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.
