Release year20242024
ProcessorIntel Core i9-14900HX: 24 cores (8 P + 16 E), 32 threads, 2.2 GHz, up to 5.8 GHz, 36 MB cache

P-cores handle games and single-threaded loads, E-cores take background and multi-core work.

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 4090 Laptop GPU, 16 GB GDDR6; 2090 MHz ROG Boost at 175 W (2040 MHz boost + 50 MHz OC; 150 W + 25 W Dynamic Boost)

175 W is the maximum GPU power when Dynamic Boost borrows budget from the CPU; the base sits at the top of NVIDIA’s 80–150 W range for this GPU. The laptop GPU is not the same product as the desktop RTX 4090.

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

Mini LED backlighting dims and lights zones behind the LCD so dark areas look deeper in HDR. 240 Hz means motion at up to 240 frames per second in suitable games; G-Sync matches refresh to frame rate to reduce tearing. 100% DCI-P3 covers the cinema colour space.

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
Graphics switchingMUX Switch + NVIDIA Advanced Optimus

The MUX connects the display directly to the RTX GPU to cut latency in games; Advanced Optimus can switch without a restart.

ASUS		—
Memory2 × 32 GB DDR5-5600 SO-DIMM (64 GB), dual channel; up to 64 GB

Both slots are populated; the modules are not soldered. ASUS notes memory speed can vary with the 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
Storage2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD (RAID 0); two M.2 PCIe slots (both used)

RAID 0 joins the two SSDs into one drive for speed and capacity; if one SSD fails, all data in the array can be lost. ASUS says only single-sided SSDs are supported because of components near the M.2 slot.

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

Thunderbolt 4 can also connect an external GPU enclosure or dock. The RJ45 port does not support Power over Ethernet, only data.

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) triple band 2×2, Bluetooth 5.2

Wi-Fi 6E can use the less congested 6 GHz band with a suitable router; ASUS notes the band may be unavailable in some countries.

Battery and power90 Wh, 4-cell lithium-ion; 330 W AC adapter (20 V, 16.5 A, ø6.0 mm) and 100 W USB-C adapter

Full performance needs the 330 W adapter; the 100 W USB-C adapter is for light use and charging on the go. ASUS says the battery can reach 50% in 30 minutes with the proper adapter while the laptop is shut down. Bundled adapters can vary by country.
