Release year20242024
ProcessorIntel Core i9-14900HX; 24 cores, 32 threads, 2.2 GHz, up to 5.8 GHz, 36 MB cache

The HX series is Intel’s high-power family that brings near-desktop core counts to laptops.

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

ASUS adds a 50 MHz overclock to the 2280 MHz boost clock. Dynamic Boost shifts 25 W from the CPU to the GPU depending on load. The GPU is soldered and cannot be replaced.

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 2.5K (2560 × 1600, WQXGA) 16:10 Mini LED; 240 Hz, 3 ms, DCI-P3 100%, G-Sync, anti-glare; ROG Nebula HDR Display, Pantone Validated

Mini LED backlighting dims thousands of small LEDs in zones for higher brightness and contrast in HDR; slight halos may be visible around bright objects. ASUS states the display works with a MUX switch and NVIDIA Advanced Optimus.

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
Memory32 GB DDR5-5600 SO-DIMM (2 × 16 GB); 2 slots, up to 64 GB, dual channel

Both slots come filled; upgrading means replacing the modules. ASUS notes memory speed can vary by CPU.

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
Storage1 TB PCIe 4.0 NVMe M.2 SSD; 2 × M.2 PCIe slots

The second M.2 slot allows an additional SSD.

ASUS		1 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 (DisplayPort, G-SYNC, 40 Gbps), 1 × USB 3.2 Gen 2 Type-C (DisplayPort, power delivery, G-SYNC, 10 Gbps), 2 × USB 3.2 Gen 2 Type-A (10 Gbps), 1 × HDMI 2.1 FRL, 1 × 2.5G LAN, 1 × 3.5 mm audio

No card reader is listed. ASUS notes the LAN port does not support Power over Ethernet (PoE).

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.

Lenovo
WirelessWi‑Fi 6E (802.11ax, tri-band) 2 × 2; Bluetooth 5.2

Wi‑Fi 6E can use the less crowded 6 GHz band with compatible routers.

ASUS		Wi-Fi 6 (802.11ax) 2x2; Bluetooth 5.2 Lenovo
Battery and power90 Wh, 4-cell lithium-ion; 330 W adapter (ø6.0 mm, 20 V 16.5 A)

ASUS notes that whether the adapter is included varies by country and model. The adapter must be connected for full GPU power.
