SpecificationLenovo Legion 7i Gen 10 (16IAX10, 83KY000TCF)ASUS ROG Strix SCAR 16 (2025) G635LX
Release year20252025
ProcessorIntel Core Ultra 7 255HX; 20 cores (8 performance + 12 efficiency), 20 threads, up to 5.2 GHz, 30 MB Intel Smart Cache

This configuration also includes the Intel AI Boost NPU rated at up to 13 TOPS; the NPU is designed to run AI tasks at lower power than the graphics card.

Lenovo
Intel Core Ultra 9 275HX; 24 cores (8 P + 16 E), 24 threads, up to 5.4 GHz, 36 MB cache

Intel rates the chip at 55 W base and 160 W maximum turbo power. In this laptop ASUS allocates 55 W to the CPU in Turbo mode and an extra 25 W in Manual mode; its graphic shows up to 80 W for the CPU.

ASUS
GraphicsNVIDIA GeForce RTX 5060 Laptop GPU, 8 GB GDDR7; 2497 MHz boost, 115 W TGP, 572 AI TOPS

TGP is the power limit the graphics chip can use in this laptop; the same GPU runs slower in lower-powered chassis. The graphics chip is soldered and cannot be replaced. Lenovo also offers the RTX 5070 Laptop GPU in this chassis at 115 W.

Lenovo
NVIDIA GeForce RTX 5090 Laptop GPU; ROG Boost 1647 MHz at 175 W (150 W + 25 W Dynamic Boost); 24 GB GDDR7

175 W is the ceiling including 25 W Dynamic Boost shifted to the GPU when the CPU is lightly loaded; it is not a constant draw in every game. The RTX 5090 Laptop GPU is not the desktop RTX 5090. Graphics memory is soldered.

ASUS
Display16-inch WQXGA (2560 × 1600) OLED, 16:10; 165 Hz, 500 nits typical / 1100 nits HDR peak, 100% DCI-P3, 1,000,000:1 contrast, glossy surface, DisplayHDR True Black 1000, Dolby Vision, G-SYNC

165 Hz means the panel can show up to 165 frames per second; G-SYNC matches the refresh to the GPU’s frame rate to reduce tearing. 1100 nits is a peak value for small areas in HDR content; everyday SDR brightness is 500 nits. The panel is factory-calibrated with X-Rite and is not a touchscreen.

Lenovo
16-inch 2560×1600 (16:10) ROG Nebula HDR Mini LED; 240 Hz, 3 ms, 100% DCI-P3, anti-glare

ASUS quotes more than 2,000 local dimming zones and 1,200 nits peak; the peak applies to small HDR highlights, not sustained full-screen brightness. The panel is Pantone Validated.

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

Memory is not soldered. The highest capacity Lenovo has tested for this platform is 32 GB; both slots are filled from the factory, so an upgrade means replacing the modules.

Lenovo
DDR5-5600 SO-DIMM, two slots, dual channel; 1×32 GB or 2×16 GB; up to 64 GB

SO-DIMM modules are not soldered and can be swapped under the bottom cover. The single 32 GB module configuration runs single-channel until the second slot is filled. The product page mentions DDR5-6400 elsewhere; the spec sheet value of 5600 is used here.

ASUS
Storage1 TB M.2 2242 PCIe 4.0 x4 NVMe SSD; 2 × M.2 2280 PCIe 4.0 x4 slots

The slots are 2280-length, so a second SSD can be added. PCIe 4.0 x4 offers a theoretical 8 GB/s of bandwidth; actual speed depends on the installed SSD.

Lenovo
1 TB or 2 TB PCIe 4.0 NVMe M.2 SSD; two M.2 slots

SSDs are held by tool-less Q-Latch clips. The ASUS product page calls the slots “PCIe Gen 5 ready”, but the spec sheet says PCIe 4.0 and one independent test reported no 5.0 support. Because of nearby components, only single-sided SSDs are supported.

ASUS
Ports1 × Thunderbolt 4 / USB4 40 Gbps USB-C (USB PD 95–100 W, DisplayPort 2.1), 1 × USB-C 10 Gbps (USB PD 95–100 W, DisplayPort 2.1), 2 × USB-A 5 Gbps (one always on), 1 × HDMI 2.1 (up to 8K 60 Hz), SD card reader, 3.5 mm headset jack, slim-tip power input

Up to 3 external displays are supported alongside the built-in panel: HDMI up to 8K 60 Hz, USB-C up to 4K 60 Hz. Both USB-C ports accept 95–100 W USB-PD charging; Lenovo’s 140 W USB-C protocol works only with its own adapter. There is no wired Ethernet.

Lenovo
2× Thunderbolt 5 (120 Gbit/s; DisplayPort, power delivery, G-SYNC); 3× USB 3.2 Gen 2 Type-A (10 Gbit/s); HDMI; 2.5G LAN; 3.5 mm audio

120 Gbit/s is the Thunderbolt 5 one-way Bandwidth Boost rate; the normal bidirectional bandwidth is 80 Gbit/s. There is no card reader. The HDMI version is not stated on the spec sheet.

ASUS
WirelessWi-Fi 7 (802.11be) 2 × 2, Bluetooth 5.4; M.2 card

The wireless card sits in an M.2 slot and is not soldered.

Lenovo
Wi-Fi 7 (802.11be) tri-band 2×2; Bluetooth 5.4 ASUS
Battery and power84 Wh lithium-ion; 245 W slim-tip adapter (3-pin), Rapid Charge Pro

Lenovo rates battery life at 3.98 hours in MobileMark 30 and 7.18 hours in local 1080p video playback. Rapid Charge Pro charges to about 50% in 30 minutes.

Model and configuration—G635LX · Intel Core Ultra 9 275HX · RTX 5090 Laptop GPU

ASUS's US spec page shows two G635LX configurations: Windows 11 Home, 1×32 GB, 1 TB, and Windows 11 Pro, 2×16 GB, 2 TB. The G635LW with the RTX 5080 Laptop GPU is a separate model.

ASUS
NPU—Intel AI Boost, up to 13 TOPS

TOPS is trillions of operations per second the neural accelerator can perform (Int8). 13 TOPS is below the 40 TOPS Microsoft asks for Copilot+ PCs.

ASUS
GPU switching—NVIDIA Advanced Optimus and Dynamic Boost (Max-Q technologies)

Advanced Optimus can route the panel straight to the discrete GPU when a game starts without a reboot, and fall back to integrated graphics on the desktop to save battery.

ASUS
Variable refresh and HDR—NVIDIA G-SYNC; Dolby Vision

G-SYNC matches the panel refresh to the GPU frame rate to reduce tearing. The spec sheet also lists G-SYNC for external displays connected over Thunderbolt 5.

ASUS
Panel coating—Dual ACR (anti-reflection) layer

ASUS says the layer reduces reflections and improves contrast by 4.5x; this is a manufacturer claim.

ASUS
Cooling—End-to-end vapor chamber, sandwiched heatsink, three fans; liquid metal on CPU and GPU

The third auxiliary fan moves heat from the GPU and VRAM to the heatsinks. The up-to-15 °C drop ASUS quotes for liquid metal comes from its internal test against the previous-generation compound.

ASUS
Power modes—Turbo: CPU 55 W + GPU 175 W (230 W total); Manual: CPU 80 W + GPU 175 W (255 W total)

These are the manufacturer ceilings under simultaneous full load; in Silent mode the GPU runs at a far lower limit.

ASUS
Service access—Tool-less bottom cover: access to two SO-DIMM slots, two M.2 slots and fans

ASUS says the mainboard frame comes off with a few screws. An independent test reported that the Wi-Fi module is soldered.

ASUS
Keyboard—Per-key RGB chiclet keyboard, ROG Overstroke; NumberPad on the touchpad; Copilot key

Overstroke registers a press earlier in the key travel. ASUS rates the switches for 20 million presses and lists n-key rollover.

ASUS
Lighting—AniMe Vision lid display (810 LEDs), wraparound light bar, AURA Sync logo

All lighting can be switched off.

ASUS
Camera and audio—1080p FHD IR camera (Windows Hello); four speakers, Smart Amp, Dolby Atmos; array microphone

The camera has no mechanical shutter.

ASUS
Battery and adapter—90 Wh, 4-cell lithium-ion; 380 W adapter (20 V/19 A)

The Thunderbolt 5 ports accept power delivery; with a lower-power USB-C charger the battery can still drain under gaming load.

ASUS
Security—Firmware TPM, BIOS password ASUS
