ASUS ROG Strix SCAR 16 (2025) G635LX / MSI Titan 18 HX AI A2XWJG-070

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.

MSI says OverBoost Ultra can allocate up to 270 W combined to the CPU and GPU; the actual figure depends on the application.

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.

The laptop version does not share the desktop RTX 5090’s configuration or power, so its performance is not the same either.

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.

MSI lists VESA DisplayHDR 1000 certification and about 100% DCI-P3 colour coverage. Mini LED splits the backlight into zones, deepening blacks in dark scenes, though a faint halo can appear around bright objects.

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 at MSI’s stated maximum; both slots are filled, so memory cannot be added, only swapped.

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.

MSI lists four M.2 slots: one PCIe 5.0 x4 and three PCIe 4.0 x4. This SKU ships with three drives; MSI mentions Super RAID 5 support.

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.

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.

A vapor chamber spreads heat over a wide surface, helping the CPU and GPU sustain high power for longer.

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.

Dynamic Boost shifts spare power to the GPU when the processor draws less; 175 W is the upper limit for this laptop GPU.

USB-C charging is capped at 140 W; MSI recommends a 65–140 W USB-PD adapter. Full performance needs the included 400 W adapter.

It gives vibration feedback instead of a physical click; the surface is merged into the palm rest.

The IR sensor enables Windows Hello face sign-in.

The global spec table lists up to 96 GB of DDR5-6400 for this chassis; actual memory speed can vary with the module and processor combination.
