Performance scores
The G15 sibling with the bigger card
The 2021 ROG Zephyrus G15 GA503 answers the G14 with a 15-inch body, a 3050 Ti instead of the 1650, and 48 GB of RAM at the same $590. The mobility index of 42 still runs half above the class median; the 90 Wh huge-tier battery anchors endurance. The flagged weakness is the 48 GB memory against the shelf's 64.
The absolute levels show what the bigger card buys: gaming 80 high against the G14's 66, general performance 74.95 high, photo and design 83 high, office 85.13 top, value 84.1 high. Portability reads 43 mid — the diagonal's cost against the G14's 65.3 high. Choosing between the siblings chooses frames versus carry, with the same green sheet underneath.
Flags green at the tier
Overwatch, Grand Theft Auto V, and Rainbow Six Siege clear recommended; Photoshop and Visual Studio Code clear minimums. Both siblings hold full green sheets; the silicon tier sets the difference.
Depreciation math
The anchor reads 13.44% yearly with no base price attached. Five years in at $590, the value index of 84.1 — high band — matches the G14: same curve, same family.
Who should buy it
The buyer who read the G14's sheet and wants the stronger GPU tier, accepting the portability drop from high band to mid. The 90 Wh cell is the upgrade the bigger body carries for free.
Bottom line: gaming 80 high, photo and design 83 high, office 85.13 top, performance 74.95 high, value 84.1 high — the G15's sheet improves on its sibling exactly where the bigger card works, and the 90 Wh huge-tier cell anchors the endurance. The portability index at 43 mid prices the diagonal against the G14's 65.3 high; the 48 GB memory flag repeats the family note. Five green flags and a 13.44% curve fully absorbed at $590 — choosing between the siblings chooses frames versus carry, with capability guaranteed either way.
