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 9 270; 8 cores, 16 threads, 4.0–5.2 GHz, 24 MB cache; AMD XDNA NPU up to 16 TOPS

The NPU is a separate block for AI tasks; TOPS means trillions of operations per second. See the glossary page for details on the Zen 4 architecture.

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 Laptop GPU; 8 GB GDDR7; 1595 MHz (1545 MHz boost clock + 50 MHz OC); 100 W + 15 W Dynamic Boost

Dynamic Boost shifts 15 W to the GPU when the CPU needs less, for 115 W in total. ASUS quotes the clock speed at a 55 W condition.

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		16-inch FHD+ 16:10 (1920 × 1200), IPS-level, anti-glare; 100% sRGB; 165 Hz, 3 ms; G-Sync; MUX Switch + Advanced Optimus

Advanced Optimus switches between integrated and discrete GPUs without a restart, saving battery on the desktop and using a direct NVIDIA path in games.

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		2 × 16 GB DDR5-5600 SO-DIMM (32 GB); 2 slots, max 64 GB

The SO-DIMM modules are replaceable; 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 adding storage without removing the existing 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 × USB4 Type-C (DisplayPort, 40 Gbit/s); 1 × USB-C 3.2 Gen 2 (DisplayPort, power delivery, G-Sync); 2 × USB-A 3.2 Gen 2; 1 × USB-A 2.0; HDMI 2.1 FRL; RJ45; 3.5 mm audio jack

The USB4 port provides 40 Gbit/s data and display output; G-Sync is listed only on the USB-C 3.2 port wired to the NVIDIA GPU.

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.
