ProcessorIntel Core Ultra 9 290HX Plus ASUSIntel 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.

GraphicsGeForce RTX 5080 Laptop GPU; distinct from the desktop RTX 5080 ASUSNVIDIA 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.

Display18-inch Mini LED; 2560 × 1600, 16:10 ASUS18-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.

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.

Ports—2 × 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
Wireless—Wi-Fi 7 (802.11be, tri-band, 2 × 2); Bluetooth 5.4

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