ROG Strix G18 (2026) G815: the desktop replacement at the edge of the scale
The ROG Strix G18 (2026) G815 is ASUS's current-year 18-inch flagship shell: the same Core Ultra 9 290HX Plus and RTX 5060 platform as the G16, stretched onto the biggest body in the batch. It posts the wave's top performance reading — and the catalog's floor carry numbers, portability itself reading zero.
Where it holds up
Graphics is the flagged strength: 87.97 against a whole-catalog median of 32.85, a 168 percent edge, enthusiast band and top quarter of the field. Performance reads 87.97, top band — the highest compute reading of this batch's 2026 wave. Reliability reads 100, the top of the scale, and the office index reaches 95 top band. The enthusiast engine, the perfect years reading and the 18-inch canvas make the desk-bound brief explicit: this machine is built to stay plugged in.
Where it falls short
The flagged weakness is mobility: 1 against a whole-catalog median of 48, 98 percent below the field middle — and portability reads 0, the catalog's floor. These are not flaws so much as the design's physics stated as data. Gaming's composite of 60 is mid-band despite the enthusiast engine — the 50-series receipts-pending pattern again, with no flags recorded to close the gap — and modeling 38 and CAD 38 sit mid-band with the same caution.
Price and depreciation
No listing price is recorded for this configuration, and no depreciation curve is modeled — so there is no resale math to quote and no dollar projection to weigh.
Alternatives to consider
The ROG Strix G16 (2026) G615 in this batch is the same platform in the saner body — portability 17.2 against 0, graphics 84.49 against 87.97 — the rational seat unless the 18-inch canvas is the point. The Legion 5 17" (2021) offers the used benchmark — top-band gaming 87 — if a proven sheet matters more than platform youth.
Bottom line
Fairly priced for the class, the ROG Strix G18 (2026) G815 is the wave's extremity: top-band performance and top-of-scale reliability on an 18-inch desk chassis — with mobility 1 and portability 0 recorded as the honest price of the form.
