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.

Frequently asked questions

01 How do I tell which ROG Zephyrus G15 generation I have?
Flip the laptop over and read the model number on the bottom label. GA502 is the 2019–2020 generation (GTX 1660 Ti or RTX 2060, FHD screen); GA503Q is the 2021 model (Ryzen 5000, RTX 30-series, QHD 165Hz); and GA503R is the 2022 model (Ryzen 9 6900HS, QHD 240Hz, MUX switch). The quickest tell is your graphics card: a GTX 1660 Ti or RTX 2060 means the 2019–2020 GA502, while any RTX 3060/3070/3070 Ti/3080 means a 2021 or 2022 GA503. See our guide to finding your laptop's model number for help reading the label or checking it in Windows.
02 Can I trade in a Zephyrus G15 with wear or hardware issues?
Yes. We buy these in a wide range of conditions — flawless units, machines with worn or swollen batteries, loud or failing fans, dead pixels or a cracked screen, sticky keys, or power problems. Set your cosmetic and functional condition accurately in the tool above (including any boxes under "Check issues that apply") and your offer adjusts to match.
03 Should I remove or wipe my SSD before shipping?
Back up your games and personal files to an external drive or the cloud, then sign out of Windows and your accounts before boxing the laptop. You don't need to unscrew or pull the M.2 NVMe drives yourself — our team runs certified, multi-pass data sanitation on every incoming machine. You can review the full process on our data erasure protocols page.
04 Which configurations raise my G15 trade-in value the most?
Generation and GPU drive value most. A newer 2022 GA503R with a Ryzen 9 6900HS and RTX 3080 (or 3070 Ti) and the QHD 240Hz panel sits at the top of the range, followed by the 2021 GA503 with an RTX 3080. The 2019–2020 GA502 with a GTX 1660 Ti is the entry tier. Within any generation, more storage (1TB), more RAM (32GB), and the higher GPU all lift your offer. For broader tips, see our computer trade-in value guide.
05 What is the turnaround process for my cash payout?
After you accept your offer, we email a free, fully insured shipping label. Once your Zephyrus G15 arrives and our intake team finishes functional and cosmetic testing, payment is approved within two business days. We pay via PayPal, Venmo, Zelle, CashApp, or ACH transfer, with a mailed paper check also available. Your offer stays valid for 30 days from checkout.
