Specification	ASUS ROG Strix SCAR 18 (2025) G835LX	Lenovo Legion Pro 7 16IRX9H (83DE0005US)
Release year	2025	2024
Processor	Intel Core Ultra 9 275HX (24 cores / 24 threads, up to 5.4 GHz, 36 MB cache, 13 TOPS NPU) The cores are a mix of performance and efficiency cores; there is no Hyper-Threading, so core and thread counts are equal. 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
Graphics	NVIDIA GeForce RTX 5090 Laptop GPU; 24 GB GDDR7; ROG Boost 1647 MHz; 175 W (150 W TGP + 25 W Dynamic Boost) 1647 MHz is the 1597 MHz boost clock plus a 50 MHz ASUS overclock. 175 W is the highest total graphics power; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered and cannot be upgraded. 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
GPU switching	MUX Switch and NVIDIA Advanced Optimus The MUX switch connects the internal display directly to the NVIDIA GPU to reduce latency in games; Advanced Optimus does this switch without a restart. ASUS	—
Display	18-inch ROG Nebula HDR Mini LED; 2560 × 1600 (16:10); 240 Hz; 100% DCI-P3; G-Sync; anti-glare low-reflection (AGLR) surface; Pantone Validated The Mini LED backlight dims in many small zones independently, which keeps dark areas dark in HDR content; it is not as precise as pixel-level OLED control. 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
Memory	64 GB (2 × 32 GB) DDR5-5600 SO-DIMM; 2 slots; up to 64 GB Both slots are filled in this variant and ASUS’s stated maximum is already reached; an upgrade means replacing the modules. 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
Storage	2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD, RAID 0; 2 × M.2 slots RAID 0 combines the two drives into one fast volume; if either drive fails all data can be lost, so regular backups matter. ASUS states that only single-sided SSDs are supported. 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
Ports	2 × Thunderbolt 5 (USB-C; DisplayPort, Power Delivery, G-SYNC); 3 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; 2.5G LAN; 3.5 mm combo audio jack Thunderbolt 5 can offer up to 120 Gb/s in one direction, useful for fast external storage and high-resolution monitors. Independent testing criticised the lack of rear ports. 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
Wireless	Wi-Fi 7 (802.11be, tri-band, 2 × 2); Bluetooth 5.4 A compatible router is needed to benefit from Wi-Fi 7 speeds. ASUS	Intel Killer Wi-Fi 6E AX1675i, 802.11ax 2×2 + Bluetooth 5.3 Lenovo
Keyboard and camera	Per-key RGB keyboard with numeric keypad and Copilot key; 1080p IR camera (Windows Hello) ASUS	—
Audio	4 speakers; Dolby Atmos; Hi-Res audio; AI noise cancelation ASUS	—
Battery and power	90 Wh 4-cell lithium-ion battery; 380 W adapter; plus a 100 W USB-C adapter The 380 W adapter is needed for gaming performance; the 100 W USB-C adapter is for light use and charging on the go. ASUS notes that box contents can vary by region. 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. Lenovo
Operating system	Windows 11 Pro ASUS	Windows 11 Home Lenovo
Lighting	AniMe Vision dot-matrix display on the lid; Aura Sync light bar ASUS	—
Size and weight	39.9 × 29.8 × 2.35–3.20 cm; 3.30 kg The carried weight rises noticeably with the adapters. ASUS	—
In the box	ROG backpack, ROG Fusion II 300 headset, ROG Gladius III Mouse P514 ASUS notes that accessories can vary by region. ASUS	—
Keyboard and touchpad	—	6-row with numeric keypad, 1.5 mm key travel; per-key RGB backlight; 75 × 120 mm buttonless Mylar surface, Precision TouchPad Lenovo
Audio and camera	—	HARMAN stereo speakers (2 W × 2, super linear), Nahimic Audio, smart amplifier; dual microphones; FHD 1080p camera with electronic shutter (E-shutter) Lenovo
Cooling	—	Hybrid cooling: air cooling + liquid-metal thermal interface Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate. Lenovo
Security	—	Firmware TPM 2.0, BIOS passwords, self-healing BIOS, camera E-shutter; no fingerprint reader Lenovo
Chassis, size and weight	—	Aluminium top and bottom, anodised, Eclipse Black; 363.5 × 262.1 × 21.95–25.9 mm; about 2.62 kg Lenovo
