The ASUS ROG Zephyrus G15 is ASUS's ultraslim 15.6-inch all-AMD gaming line, and this page covers three distinct generations sold under the same name: the 2019–2020 GA502 (Ryzen 3000/4000-series with GTX 1660 Ti or RTX 2060), the 2021 GA503 (Ryzen 5000-series "Zen 3" with RTX 30-series and a QHD 165Hz panel), and the 2022 GA503 (Ryzen 6000-series with RTX 30-series and a QHD 240Hz panel plus MUX switch). Because the chassis name stayed the same while the internals changed dramatically year to year, your exact processor and graphics card determine both which generation you own and your final resale price. Use the selectors above to match your CPU and GPU, then view an instant cash offer for your precise machine.
Identify your Zephyrus G15 generation
The fastest way to tell these apart is the model number on the underside (begins with GA502 or GA503) combined with your graphics card. Your GPU maps cleanly to one generation:
2019–2020 — GA502
- GPU: GTX 1660 Ti or RTX 2060 (Max-Q)
- CPU: Ryzen 7 3750H, Ryzen 7 4800HS, or Ryzen 9 4900HS
- Display: FHD (1920 × 1080), 60/120/144/240Hz
2021 — GA503 (Zen 3)
- GPU: RTX 3060 / 3070 / 3080 (100W class)
- CPU: Ryzen 7 5800HS or Ryzen 9 5900HS
- Display: QHD (2560 × 1440), 165Hz
2022 — GA503R
- GPU: RTX 3060 / 3070 Ti / 3080 (120W class)
- CPU: Ryzen 9 6900HS
- Display: QHD (2560 × 1440), 240Hz + MUX switch
The selector above lists CPU as Ryzen 7 / Ryzen 9 and GPU from GTX 1660 Ti up to RTX 3080 — pick the GPU first, since it pins down your generation. Need help locating the model number? See our guide to finding your laptop's model number.

Battery, build & more
Battery & charging
The 2021 and 2022 GA503 carry a large 90Wh battery and dual charging: a 200W or 240W barrel adapter (by GPU tier) plus 100W USB-C Power Delivery. The 2019–2020 GA502 uses a smaller battery with a barrel adapter and Type-C charging support.
Camera
The 2022 GA503R adds a 720p HD IR webcam with Windows Hello. Earlier GA502 and 2021 GA503 models shipped without a built-in webcam.
