Release year20252024
ProcessorIntel Core Ultra 9 275HX; 2.1–5.4 GHz

Arrow Lake-HX generation 24-core processor (8 performance, 16 efficiency) on the Intel HM870 chipset. There is no Hyper-Threading, so each core runs one thread.

MSI		Intel Core i9-14900HX: 24 cores, 32 threads, 2.2 GHz base, up to 5.8 GHz, 36 MB cache ASUS
GraphicsNVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; 150 W maximum graphics power with Dynamic Boost; up to 1875 MHz boost

The laptop RTX 5090 is not the same card as the desktop RTX 5090. 150 W is the ceiling MSI sets for this thin chassis, so slightly lower GPU performance than thicker 175 W models is expected. MSI quotes 1824 AI TOPS.

MSI		NVIDIA GeForce RTX 4070 Laptop GPU, 8 GB GDDR6; ROG Boost 2225 MHz at 140 W (115 W + 25 W Dynamic Boost)

140 W is the top of NVIDIA’s allowed power range for the RTX 4070 Laptop GPU; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered to the board.

ASUS
Display18-inch UHD+ 3840 × 2400, 120 Hz, Mini LED, HDR 1000, 100% DCI-P3; matte surface

The 16:10 panel is an LCD lit from behind by many small LED zones; local dimming gives high brightness and contrast in HDR content, though halos can appear around bright objects in dark scenes. MSI’s family page describes the panel as "IPS-Level".

MSI		18-inch ROG Nebula, 2560 × 1600 (16:10), IPS-level, 240 Hz, 3 ms; 100% DCI-P3; G-Sync; Pantone Validated; anti-glare

240 Hz shows motion more smoothly and with less blur in fast games; G-Sync matches the refresh to the frame rate to reduce tearing.

ASUS
Memory64 GB (2 × 32 GB) DDR5-5600; 2 SO-DIMM slots, up to 96 GB

Both slots come populated, so an upgrade means replacing the modules. MSI lists support up to DDR5-6400; the actual speed depends on the memory combination and the CPU.

MSI		32 GB (2 × 16 GB DDR5-5600 SO-DIMM); 2 SO-DIMM slots, dual channel

Because both slots are filled, upgrading means replacing the installed modules; memory speed depends on the processor’s support.

ASUS
Storage2 TB NVMe PCIe Gen4 x4 SSD; 1 M.2 slot

There is no second SSD slot; MSI advises consulting a service centre before upgrading the SSD.

MSI		2 TB PCIe 4.0 NVMe M.2 SSD; 2 M.2 PCIe slots in total (including the one in use) ASUS
Ports2 × Thunderbolt 4 (DisplayPort / Power Delivery 3.1); 2 × USB 3.2 Gen 2 Type-A; 1 × HDMI 2.1 (8K 60 Hz / 4K 120 Hz); 1 × RJ45; 1 × headset combo jack

Thunderbolt 4 carries 40 Gbit/s data and video over the USB-C shaped port. This model has no Thunderbolt 5.

MSI		1 × Thunderbolt 4 (40 Gb/s, DisplayPort); 1 × USB 3.2 Gen 2 Type-C (DisplayPort, charging, G-SYNC); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; RJ45 LAN; 3.5 mm combo audio

USB-C charging is supported only on the USB 3.2 Gen 2 port; the Thunderbolt 4 port does not take charge. There is no SD card reader.

ASUS
Card reader1 × SD Express card reader

SD Express uses a PCIe/NVMe interface for much faster transfers with compatible cards; ordinary SD cards are still read.
