Release year20252025
ProcessorIntel Core Ultra 9 275HX (24 cores / 24 threads, up to 5.4 GHz, 36 MB cache, 13 TOPS NPU)

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

ASUS		AMD Ryzen AI 9 HX 370 (12 cores / 24 threads, 2.0–5.1 GHz, 36 MB cache); 50 TOPS XDNA NPU ASUS
GraphicsNVIDIA GeForce RTX 5090 Laptop GPU; 24 GB GDDR7; ROG Boost 1647 MHz; 175 W (150 W TGP + 25 W Dynamic Boost)

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.

ASUS		NVIDIA GeForce RTX 5070 Ti Laptop GPU; 12 GB GDDR7; 1812 MHz at 110 W in Turbo mode (85 W + 25 W Dynamic Boost)

110 W is the ceiling reached only in the Turbo profile when CPU load allows. The GA403UP version with the RTX 5070 Laptop in the same chassis is limited to 90 W and 8 GB.

ASUS
GPU switchingMUX Switch and NVIDIA Advanced Optimus

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.

Display18-inch ROG Nebula HDR Mini LED; 2560 × 1600 (16:10); 240 Hz; 100% DCI-P3; G-Sync; anti-glare low-reflection (AGLR) surface; 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.

ASUS		14-inch 3K (2880 × 1800) OLED, 16:10; 120 Hz; 100% DCI-P3; Pantone Validated

Pantone Validated means the screen reproduces Pantone colours with factory-measured accuracy, reducing colour shifts in photo and video editing.

ASUS
Memory64 GB (2 × 32 GB) DDR5-5600 SO-DIMM; 2 slots; up to 64 GB

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

ASUS		32 GB LPDDR5X 8000 soldered; no expansion slot ASUS
Storage2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD, RAID 0; 2 × M.2 slots

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.

ASUS		1 TB PCIe 4.0 NVMe M.2 SSD; one M.2 slot in total

With the only slot occupied, adding capacity means replacing the drive.

ASUS
Ports2 × Thunderbolt 5 (USB-C; DisplayPort, Power Delivery, G-SYNC); 3 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; 2.5G LAN; 3.5 mm combo audio jack

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.

ASUS		1 × USB4 Type-C (40 Gbit/s, DisplayPort, power delivery); 1 × USB 3.2 Gen 2 Type-C (DisplayPort, power delivery, G-Sync); 2 × USB 3.2 Gen 2 Type-A; UHS-II microSD; 3.5 mm; XG Mobile GC34 support

ASUS documents G-Sync for external displays only on the USB 3.2 Type-C output. XG Mobile is ASUS’s external graphics enclosure.

ASUS
WirelessWi-Fi 7 (802.11be, tri-band, 2 × 2); Bluetooth 5.4

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

Battery and power90 Wh 4-cell lithium-ion battery; 380 W adapter; plus a 100 W USB-C adapter

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.
