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 Ultra 9 185H; 16 cores, 22 threads, 2.3 GHz base, up to 5.1 GHz, 24 MB cache; Intel AI Boost NPU (up to 11 TOPS)

The NPU is a separate unit for running AI tasks at low power. Intel lists 45 W base and 115 W maximum turbo power for this processor.

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 4060 Laptop GPU, 8 GB GDDR6; ROG Boost 1940 MHz at 100 W (85 W + 15 W Dynamic Boost)

Because of the thin chassis, the power limit is lower than in thicker gaming laptops that run the same GPU at up to 140 W, which can mean lower frame rates under load. The GPU is soldered.

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		ROG Nebula: 16-inch 2.5K (2560 × 1600) 16:10, IPS-level, anti-glare low-reflection (AGLR); 240 Hz, 3 ms, 100% DCI-P3, G-Sync, Pantone Validated

This QP version uses an IPS-level panel; the QR-coded versions have a 0.2 ms OLED panel.

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-7467 soldered on board; not upgradeable

ASUS states there is no memory slot in this configuration; capacity must be chosen at purchase.

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		2 TB PCIe 4.0 NVMe M.2 SSD; 2 × M.2 PCIe slots

The second M.2 slot is for 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, power delivery, 40 Gbps), 1 × USB 3.2 Gen 2 Type-C (DisplayPort, power delivery, 10 Gbps), 2 × USB 3.2 Gen 2 Type-A, 1 × HDMI 2.1 FRL, SD card reader (UHS-II, 312 MB/s), 3.5 mm audio jack; XG Mobile GC34 support

Both USB‑C ports accept charging. There is no wired network (RJ45) port. XG Mobile GC34 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.

ASUS		90 Wh, 4-cell lithium-ion; 200 W adapter with rectangular connector; ASUS also lists a 100 W USB‑C adapter

USB‑C charging works, but full performance needs the 200 W adapter. ASUS says included adapters vary by country and model.
