ASUS ROG Strix SCAR 16 (2025) G635LX / Lenovo Legion Pro 5i Gen 10 (RTX 5070 Ti, OLED)

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.

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.

The platform also offers the Core Ultra 7 251HX; this entry covers the Core Ultra 9 275HX configuration. The chipset is Intel HM870.

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.

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.

TGP is the maximum power the graphics card can draw in this laptop; the same GPU at a lower TGP is slower in games. The GPU is soldered to the board and cannot be replaced.

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 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.

Some configurations of the same platform use a 240 Hz OLED panel; this MTM has the 165 Hz panel.

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

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.

Memory is replaceable, but Lenovo does not support more than 32 GB on this platform.

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.

Two slots allow a second SSD; PCIe 4.0 x4 offers a theoretical 8 GB/s of bandwidth.

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.

USB-C charging is limited to 100 W; 140 W needs a Lenovo-specific adapter. HDMI 2.1 outputs up to 8K 60 Hz, and the 10 Gbps USB-A port charges devices while the laptop is off.

The wireless card sits in an M.2 slot.

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.

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

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

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

All lighting can be switched off.

The camera has no mechanical shutter.

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

Adapter weight not included.

Advanced Optimus connects the display directly to the discrete GPU in games and switches to integrated graphics for desktop work to save battery.

The panel is factory calibrated with X-Rite and carries TUV Rheinland low blue light and flicker-free certifications.

Lenovo quotes about 3.6 hours in MobileMark 30 (250 nits) and about 8.4 hours of 1080p video playback at 150 nits.

Lenovo notes that some configurations may ship without an adapter.
