ASUS ROG Strix SCAR 16 (2025) G635LX / GIGABYTE AORUS MASTER 16 AM6H (BYHC5USE64SH)

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 includes the share Dynamic Boost shifts to the GPU when CPU load is low; GIGABYTE notes the figure may vary by scenario. The desktop RTX 5080 is a different card.

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.

240 Hz shows motion more clearly in fast games and puts the RTX 5080’s high frame rates on screen; 500 nits is an HDR peak, not sustained full-screen brightness.

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 not soldered. The BYHC5USE64SH ships with 2 × 16 GB, so both slots are filled and upgrading means swapping 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.

A second SSD can be added. The Gen5 slot gives higher sequential speeds with a compatible Gen5 SSD; which slot the factory SSD uses can vary by configuration.

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.

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.

N-key rollover means every simultaneously pressed key is registered, avoiding missed inputs in games. Lighting is set in three zones, not per key.

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.

99 Wh is close to the upper limit for laptop batteries allowed on planes. Full GPU power needs the 330 W adapter; USB-C charging via Power Delivery 3.0 is possible but performance is reduced.

Adapter weight not included.

Advanced Optimus switches the display between integrated graphics and the RTX GPU without a reboot: a direct GPU path in games, battery savings in light work.

True Black 500 certifies HDR peak brightness of 500 nits together with OLED’s deep blacks; ClearMR 10000 is a motion-clarity tier.

The Thunderbolt 5 port suits high-bandwidth external SSDs, docks and DisplayPort 2.1 monitors; HDMI 2.1 supports high-refresh TVs and monitors.

The two USB-C ports differ in speed and display version; for a high-resolution external display the left Thunderbolt 5 port is the better choice.
