Operating systemWindows 11 Home or Windows 11 Pro (depending on configuration) ASUS—
ProcessorIntel Core Ultra 9 275HX; 24 cores (8 P + 16 E), 24 threads, up to 5.4 GHz, 36 MB cache

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.

ASUS
Intel Core i9-14900HX: 24 cores, 32 threads, 2.2 GHz base, up to 5.8 GHz, 36 MB cache ASUS
NPUIntel AI Boost, up to 13 TOPS

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.

GraphicsNVIDIA GeForce RTX 5090 Laptop GPU; ROG Boost 1647 MHz at 175 W (150 W + 25 W Dynamic Boost); 24 GB GDDR7

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.

ASUS
NVIDIA GeForce RTX 4070 Laptop GPU, 8 GB GDDR6; ROG Boost 2225 MHz at 140 W (115 W + 25 W Dynamic Boost)

140 W is the top of NVIDIA’s allowed power range for the RTX 4070 Laptop GPU; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered to the board.

ASUS
GPU switchingNVIDIA Advanced Optimus and Dynamic Boost (Max-Q technologies)

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.

Display16-inch 2560×1600 (16:10) ROG Nebula HDR Mini LED; 240 Hz, 3 ms, 100% DCI-P3, anti-glare

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.

ASUS
18-inch ROG Nebula, 2560 × 1600 (16:10), IPS-level, 240 Hz, 3 ms; 100% DCI-P3; G-Sync; Pantone Validated; anti-glare

240 Hz shows motion more smoothly and with less blur in fast games; G-Sync matches the refresh to the frame rate to reduce tearing.

ASUS
Variable refresh and HDRNVIDIA G-SYNC; Dolby Vision

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.

Panel coatingDual ACR (anti-reflection) layer

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

MemoryDDR5-5600 SO-DIMM, two slots, dual channel; 1×32 GB or 2×16 GB; up to 64 GB

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.

ASUS
32 GB (2 × 16 GB DDR5-5600 SO-DIMM); 2 SO-DIMM slots, dual channel

Because both slots are filled, upgrading means replacing the installed modules; memory speed depends on the processor’s support.

ASUS
Storage1 TB or 2 TB PCIe 4.0 NVMe M.2 SSD; two M.2 slots

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.

ASUS
2 TB PCIe 4.0 NVMe M.2 SSD; 2 M.2 PCIe slots in total (including the one in use) ASUS
Ports2× Thunderbolt 5 (120 Gbit/s; DisplayPort, power delivery, G-SYNC); 3× USB 3.2 Gen 2 Type-A (10 Gbit/s); HDMI; 2.5G LAN; 3.5 mm audio

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.

ASUS
1 × Thunderbolt 4 (40 Gb/s, DisplayPort); 1 × USB 3.2 Gen 2 Type-C (DisplayPort, charging, G-SYNC); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; RJ45 LAN; 3.5 mm combo audio

USB-C charging is supported only on the USB 3.2 Gen 2 port; the Thunderbolt 4 port does not take charge. There is no SD card reader.

WirelessWi-Fi 7 (802.11be) tri-band 2×2; Bluetooth 5.4 ASUSWi‑Fi 6E (802.11ax, tri-band) 2×2 ASUS
CoolingEnd-to-end vapor chamber, sandwiched heatsink, three fans; liquid metal on CPU and GPU

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.

Power modesTurbo: CPU 55 W + GPU 175 W (230 W total); Manual: CPU 80 W + GPU 175 W (255 W total)

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

Service accessTool-less bottom cover: access to two SO-DIMM slots, two M.2 slots and fans

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

KeyboardPer-key RGB chiclet keyboard, ROG Overstroke; NumberPad on the touchpad; Copilot key

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