Performance scores
A 2025 desk-replacement that reads top-of-scale on almost every axis
The ROG Strix G18 (2025) G815 asks $1,440 on the used shelf and backs the ticket with the strongest CPU reading in the gaming class: 100 points, roughly 54% above the class median of 65. Around it, the task axes pile up — performance 94, office 98.8, gaming 100, modeling 100, CAD 100, photo design 96, all in the top band. The one axis left behind is portability at 0, the floor of the scale, and that number is the honest summary of what a 3.42 kg, 18-inch chassis costs. The configuration pairs an Intel Core Ultra 9 275HX with an RTX 5050 Laptop 8GB and 64GB of RAM.
Reliability and compute lead the sheet
The reliability index reads 94 against a class median of 53 — 77% above, in the top quartile. The CPU score of 100 is the top of the scale, and the six green capability flags (Overwatch, GTA V and Rainbow Six Siege at recommended level, plus Premiere Pro minimum, Photoshop recommended and VS Code recommended) turn the raw placing into usable claims. For compute-heavy work — compiling, encoding, multi-tab creative suites — this is among the better-evidenced 2025 tickets in the aisle.
The trade is the chassis, not the silicon
Weight is 3.42 kg, about 42% above the class median of 2.4 kg, and the portability index sits at 0 — bottom of the scale. This machine moves by plan: between desk and socket, not in a backpack. Buyers wanting the same silicon in a carryable body pay the same money elsewhere and give up the 18-inch screen; the catalog's verdict names weight as the watch-out, and nothing in the data argues with it.
No depreciation anchor
The listing carries no launch-price anchor, so no per-machine depreciation curve can be computed — the class rate of 20% per year is the only guide. A one-year-old machine at $1,440 with that class rate implies meaningful further drift; the purchase case rests on capability today, not on residual value.
Where it sits against the shelf
$1,440 is the shelf's favorite number this season — several 2025 ASUS gaming machines share it, including the SCAR 16 G635 and SCAR 18 G835 in this batch. Against those, the G815 differentiates on the 18-inch format and its top-of-scale CPU reading rather than on graphics tier, where the 5050 sits a rung below the 5070 Ti of the G635. Buyers choosing inside the $1,440 row are effectively choosing a GPU tier and a diagonal, not a quality gap.
Bottom line
For a buyer who games and computes at a desk, this is one of the most complete 2025 sheets available at $1,440: top-band readings on seven of eight task axes, a perfect CPU score, 64GB of RAM and a full set of green flags. The portability index of 0 is the price of the format, named plainly. Anyone who needs to carry the machine daily should step down a diagonal; everyone else gets capability that the shelf rarely evidences this completely at the price.
