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
Intel Core Ultra 9 275HX; 24 cores (8 P + 16 E), up to 5.4 GHz on P-cores; 36 MB cache

The platform also offers the Core Ultra 7 251HX; this entry covers the Core Ultra 9 275HX configuration. The chipset is Intel HM870.

Lenovo
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; 140 W TGP; 2220 MHz boost

TGP is the maximum power the graphics card can draw in this laptop; the same GPU at a lower TGP is slower in games. The GPU is soldered to the board and cannot be replaced.

Lenovo
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 WQXGA (2560 × 1600) OLED, glossy, 165 Hz; non-touch

Some configurations of the same platform use a 240 Hz OLED panel; this MTM has the 165 Hz panel.

Lenovo
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; 2 SO-DIMM slots, DDR5-5600 or DDR5-6400, up to 32 GB

Memory is replaceable, but Lenovo does not support more than 32 GB on this platform.

Lenovo
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 × M.2 2280 PCIe 4.0 x4 slots; up to 1 TB per drive

Two slots allow a second SSD; PCIe 4.0 x4 offers a theoretical 8 GB/s of bandwidth.

Lenovo
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 / USB4 (40 Gbps, DisplayPort 2.1); 1 × USB-C 10 Gbps (65–100 W PD, DisplayPort 2.1); 1 × USB-A 10 Gbps; 2 × USB-A 5 Gbps; HDMI 2.1; Gigabit Ethernet; 3.5 mm audio

USB-C charging is limited to 100 W; 140 W needs a Lenovo-specific adapter. HDMI 2.1 outputs up to 8K 60 Hz, and the 10 Gbps USB-A port charges devices while the laptop is off.

Lenovo
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 7 (2×2) with Bluetooth 5.4, or Wi-Fi 6 with Bluetooth 5.2 (by configuration)

The wireless card sits in an M.2 slot.
