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 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 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 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 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		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 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		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); 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		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 (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 × 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.

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.

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.
