ProcessorIntel Core i9-14900HX: 24 cores, 32 threads, 2.2 GHz base, up to 5.8 GHz, 36 MB cache ASUSIntel Core i7-13650HX; 14 cores (6 P + 8 E), 20 threads, up to 4.9 GHz

HX processors are high-power mobile chips; sustained power and fan noise depend on Lenovo’s power modes.

Lenovo
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 4060 Laptop GPU; 8 GB GDDR6; 115 W TGP with the 230 W adapter, 105 W with the 170 W adapter

TGP is the sustained power limit given to the GPU; on the same GPU a higher TGP usually means higher gaming performance. Lenovo ties TGP on this platform to the wattage of the bundled adapter.

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		15.6-inch FHD (1920 × 1080) IPS, 144 Hz, 300 nits, 100% sRGB, anti-glare; NVIDIA G-SYNC

144 Hz shows smooth motion up to 144 frames per second in games; G-SYNC matches the refresh to the GPU’s frame rate to reduce tearing.

Lenovo
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.

ASUS		—
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		24 GB DDR5-4800 (2 × 12 GB SODIMM); two slots, up to 32 GB

Memory is not soldered; both slots come filled, so an upgrade means replacing both modules. The 32 GB limit is Lenovo’s platform statement.

Lenovo
Storage2 TB PCIe 4.0 NVMe M.2 SSD; 2 M.2 PCIe slots in total (including the one in use) ASUS1 TB M.2 2242 PCIe 4.0 NVMe QLC SSD; two M.2 PCIe 4.0 x4 slots

The second M.2 slot allows an extra SSD. QLC flash can slow down sooner than TLC during long, large writes.

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 × USB-C 10 Gbps (USB PD 65–100 W input, DisplayPort 1.4); 3 × USB-A 5 Gbps; HDMI 2.1; RJ-45 gigabit Ethernet; 3.5 mm headphone/mic

Charging over USB-C works, but 140 W input needs Lenovo’s own adapter; the slim-tip port remains the main power input for gaming. There is no Thunderbolt or USB4.
