ASUS ROG Strix SCAR 16 (2025) G635LX / Lenovo Legion Pro 7 16IRX9H (83DE0005US)

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.

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.

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.

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.

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.

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.

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.

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.

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

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.

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.

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.

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.

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.

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.
