Performance scores
MSI Stealth 18 HX AI — perfect 100s on CPU, gaming and photo
The Stealth 18 HX AI at $1,440 posts the batch's most decorated scorecard: CPU score 100 — the maximum, shared with one other machine — plus gaming 100 and photo design 100, with performance at 95.11 in the top band. The platform is a Core Ultra 7 255HX with a GeForce RTX 5070 (8 GB) and 128 GB of RAM; the flagged strength is that doubled memory, and the flagged weakness is weight at 2.89 kg (+20.4%, heavy band).
Where it holds up
Six of eight axes read top: performance 95.11, office 98.45, gaming 100, modeling 99, engineering CAD 99, photo design 100 — tied with the Katana 15 (2025) for the most top-band axes in this batch, and the only machine here with three perfect 100 readings. The 128 GB memory ceiling doubles the class median, reliability posts 86 (+62.3%), and the platform clears the recommended bar for Overwatch, Grand Theft Auto V and Rainbow Six Siege plus the recommended bar for Visual Studio Code and minimum bars for Premiere Pro and Photoshop. Value reads 72.4 (high).
Where it falls short
Weight is the flagged weakness (2.89 kg) and portability reads 0 — the absolute floor, the standard cost of the 18-inch flagship format. The perfect gaming score sits on a "Stealth" badge that is nominal rather than literal; this is a performance flagship, not a traveler.
Price and depreciation
No depreciation anchor is recorded (base $0); no curve or projection applies. The 2025 cohort rate is 20% per year — the steep band that a first-year flagship purchase accepts.
Alternatives to consider
The Crosshair 18 HX AI (2025) at the same $1,440 shares the perfect CPU score with a reliability emphasis and a 96 GB ceiling; the Vector A16 HX (2025) pairs the RTX 5070 Ti with better portability. The Katana 15 (2025) matches the six-top-axis sweep in a smaller, cheaper frame.
Bottom line
Fairly priced for the class, value agreeing in the high band. The scorecard flagship of the batch: three perfect 100s and six top-band axes — buy it as a desk-bound performance machine and never for the Stealth name.
