Release year	2025	2024
Processor	Intel 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, 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
Graphics	NVIDIA 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 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
Display	18-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 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
Memory	64 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 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
Storage	2 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	1 TB PCIe 4.0 NVMe M.2 SSD; 2 × M.2 PCIe slots The second M.2 slot allows an additional SSD. ASUS
