Release year20252024
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		Intel Core i9-14900HX; 24 cores, 32 threads, 2.2 GHz, up to 5.8 GHz, 36 MB cache

The HX series is Intel’s high-power family that brings near-desktop core counts to laptops.

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 4080 Laptop GPU, 12 GB GDDR6; ROG Boost 2330 MHz at 175 W (150 W + 25 W Dynamic Boost)

ASUS adds a 50 MHz overclock to the 2280 MHz boost clock. Dynamic Boost shifts 25 W from the CPU to the GPU depending on load. The GPU is soldered and cannot be replaced.

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		18-inch 2.5K (2560 × 1600, WQXGA) 16:10 Mini LED; 240 Hz, 3 ms, DCI-P3 100%, G-Sync, anti-glare; ROG Nebula HDR Display, Pantone Validated

Mini LED backlighting dims thousands of small LEDs in zones for higher brightness and contrast in HDR; slight halos may be visible around bright objects. ASUS states the display works with a MUX switch and NVIDIA Advanced Optimus.

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 DDR5-5600 SO-DIMM (2 × 16 GB); 2 slots, up to 64 GB, dual channel

Both slots come filled; upgrading means replacing the modules. ASUS notes memory speed can vary by CPU.

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; 2 × M.2 PCIe slots

The second M.2 slot allows an additional SSD.

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 × Thunderbolt 4 (DisplayPort, G-SYNC, 40 Gbps), 1 × USB 3.2 Gen 2 Type-C (DisplayPort, power delivery, G-SYNC, 10 Gbps), 2 × USB 3.2 Gen 2 Type-A (10 Gbps), 1 × HDMI 2.1 FRL, 1 × 2.5G LAN, 1 × 3.5 mm audio

No card reader is listed. ASUS notes the LAN port does not support Power over Ethernet (PoE).

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.

ASUS		Wi‑Fi 6E (802.11ax, tri-band) 2 × 2; Bluetooth 5.2

Wi‑Fi 6E can use the less crowded 6 GHz band with compatible routers.
