ASUS ROG Strix SCAR 16 (2025) G635LX / ASUS ROG Strix SCAR 18 (2025) G835LX

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 cores are a mix of performance and efficiency cores; there is no Hyper-Threading, so core and thread counts are equal.

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.

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.

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.

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 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.

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.

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.

Both slots are filled in this variant and ASUS’s stated maximum is already reached; an upgrade means replacing the modules.

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.

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.

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.

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.

A compatible router is needed to benefit from Wi-Fi 7 speeds.

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.

The carried weight rises noticeably with the adapters.

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.
