The ASUS ROG Zephyrus G16 (GU605) is ASUS's slim, premium 16-inch gaming and creator laptop, sold across two closely related Intel-based generations that share the same model number and near-identical CNC aluminum chassis with the diagonal "Slash Lighting" LED bar on the lid. The 2024 model (released early 2024) runs on Intel Core Ultra "Meteor Lake" processors with NVIDIA GeForce RTX 40-series graphics, while the 2025 model (released early 2025) steps up to Intel Core Ultra 200-series "Arrow Lake" processors with NVIDIA GeForce RTX 50-series graphics. Because these two years look almost the same on the outside but carry very different internals, your exact configuration and generation determine your final cash offer. Many owners use our gaming laptop trade-in service to sell theirs online for cash without listing it themselves. Select your components using our tool above to view an instant offer for your exact device.

First, confirm which Zephyrus G16 you have

Both generations carry the base model number GU605. The reliable way to tell them apart is the letter directly after "GU605" in the full model code (found on the sticker on the bottom of the laptop) combined with the processor name. Not tech-savvy? On Windows, press the Windows key, type msinfo32, press Enter, and read the "System Model" and "Processor" lines — that tells you everything below.

✅ This is the 2024 model

  • Model code begins GU605M (e.g. GU605MI, GU605MV, GU605MZ, GU605MY, GU605MU)
  • Processor reads Intel Core Ultra 7 155H or Intel Core Ultra 9 185H ("Meteor Lake")
  • Graphics: NVIDIA GeForce RTX 4050 / 4060 / 4070 / 4080 / 4090

✅ This is the 2025 model

  • Model code begins GU605C (e.g. GU605CR, GU605CW, GU605CX, GU605CP)
  • Processor reads Intel Core Ultra 9 285H ("Arrow Lake")
  • Graphics: NVIDIA GeForce RTX 5070 / 5070 Ti / 5080 / 5090

❌ Not this page if…

  • GA605 (with an "A") — that's the AMD Ryzen Zephyrus G16, a different machine
  • GU603 — that's the older 2023 Zephyrus G16
  • GU606 — that's the newer 2026 Zephyrus G16 (Intel Panther Lake)
  • A 14-inch GA403 / GA402 — that's the smaller Zephyrus G14

Need help finding the model code?

The full code is laser-printed on the label on the underside of the laptop, and also appears in msinfo32 as described above. Our step-by-step ASUS model number guide walks you through it with pictures.

Core hardware by generation

Processor (CPU)

  • 2024 (GU605M): Intel Core Ultra 7 155H (16 cores, 22 threads, up to 4.8 GHz) or Intel Core Ultra 9 185H (16 cores, 22 threads, up to 5.1 GHz) — both "Meteor Lake" with Intel AI Boost NPU
  • 2025 (GU605C): Intel Core Ultra 9 285H (16 cores, 16 threads, up to 5.4 GHz) — "Arrow Lake" with a 13 TOPS NPU

Graphics (GPU)

  • 2024: NVIDIA GeForce RTX 4050, 4060, 4070, 4080, or 4090 Laptop GPU (up to 8GB / 12GB / 16GB GDDR6 depending on tier)
  • 2025: NVIDIA GeForce RTX 5070, 5070 Ti, 5080, or 5090 Laptop GPU (up to 24GB GDDR6 on the 5090), with DLSS 4 Multi Frame Generation
  • All configurations feature a MUX Switch + NVIDIA Advanced Optimus for direct GPU output

Memory (RAM)

  • Soldered LPDDR5X — not upgradable. The RAM is fixed to the motherboard on both generations, so the capacity your laptop shipped with is permanent
  • 2024: 16GB or 32GB LPDDR5X-7467 (max 32GB)
  • 2025: 16GB, 32GB, or 64GB LPDDR5X-8000 depending on config (max 64GB)

Storage

  • M.2 PCIe 4.0 NVMe SSD (user-replaceable)
  • 2024: 512GB / 1TB / 2TB — two M.2 2280 slots
  • 2025: 1TB / 2TB — single M.2 2280 slot on most configs

Display & audio

Display

Both generations use the same headline ROG Nebula 16-inch panel: 2.5K (2560 × 1600, WQXGA), 16:10 aspect ratio, OLED, 240Hz refresh, 0.2ms response, G-SYNC, 100% DCI-P3, Pantone Validated, and Dolby Vision HDR. A small number of entry 2024 units shipped with a 2.5K IPS panel instead of OLED — check yours if you're unsure, since the OLED panel is worth more.

Audio

Six-speaker system (two force-canceling woofers plus tweeters) with Dolby Atmos and Smart Amp technology, tuned for the thin chassis with surprisingly strong output for its size.

Ports & connectivity

The G16's port layout is largely shared between the two years, split across both sides of the slim chassis.

Left Side
  • 1× Power adapter input (DC-in, barrel connector)
  • 1× HDMI 2.1 (FRL)
  • 1× USB-C Thunderbolt 4 (2024) / Thunderbolt / USB4 40 Gbps (2025) — both support DisplayPort and USB Power Delivery charging
  • 1× 3.5mm headphone/microphone combo jack
Right Side
  • 1× USB-C 3.2 Gen 2 (with DisplayPort + Power Delivery)
  • 2× USB-A 3.2 Gen 2
  • 1× microSD card reader (UHS-II) — note this is a microSD reader, not a full-size SD slot

Wi-Fi 6E (2024) Wi-Fi 7 (2025) Bluetooth 5.3 / 5.4 1080p IR webcam (Windows Hello)

Battery, build & more

Battery & charging

90Wh battery on both generations. Charging is handled by a compact USB-C adapter on lower-tier GPUs (100W–140W) or a larger barrel-plug adapter on higher-tier RTX configs (200W on 2024 top models, up to 240W on 2025 top models). Including the correct original charger meaningfully helps your offer.

Keyboard & touchpad

Full-size backlit chiclet keyboard (single-zone RGB) with 1.7mm travel and a large glass ClickPad. The 2025 model swaps the right Ctrl key for a dedicated Copilot key — a quick way to spot a 2025 unit.

Cooling

Tri-fan or dual-fan design (varies by GPU tier) with a vapor chamber on higher-end models, liquid-metal thermal compound on the CPU, and ROG's Armoury Crate control software.

Weight & dimensions

≈ 1.85–2.0 kg (4.1–4.4 lb) depending on config. Roughly 354 × 246 × 15–17 mm — a genuinely thin-and-light 16-inch gaming laptop with a CNC aluminum unibody.

Frequently asked questions

01 How do I confirm I have the ASUS ROG Zephyrus G16 (GU605), and which year?
Flip the laptop over and read the label on the bottom cover — you're looking for a code starting with GU605. The letter right after it tells you the year: GU605M… is the 2024 model (Intel Core Ultra 7 155H or Core Ultra 9 185H) and GU605C… is the 2025 model (Intel Core Ultra 9 285H). If the sticker is worn off, press the Windows key, type msinfo32, hit Enter, and check the "System Model" and "Processor" lines. Our ASUS model number guide shows exactly where to look.
02 My laptop just says "Zephyrus G16" — how do I know it's not a different model?
ASUS has sold several look-alike machines under similar names, so the exact model code matters for an accurate quote. This page is only for the Intel GU605 (2024 and 2025). It is not for the GA605 — that "A" means the AMD Ryzen version, which is a separate machine. It's also not the GU603 (the 2023 G16), the GU606 (the 2026 G16), or the smaller 14-inch Zephyrus G14 GU405. If your code doesn't start with GU605, use the search bar on our homepage to find the right page — quoting the wrong model can result in a revised offer after inspection.
03 Can I sell a Zephyrus G16 that has wear, a cracked screen, or won't turn on?
Yes. We buy these laptops in every condition — flawless, cosmetically scuffed, dented, cracked OLED screen, swollen or dead battery, keyboard faults, or fully non-booting. Just describe the condition honestly in the tool above, and your offer adjusts accordingly. Even a machine that won't power on retains value because its GPU, SSD, and other components are still worth money. One OLED-specific note: if the screen has permanent image retention or "burn-in," mention it, as it affects grading.
04 Which configurations raise my G16 trade-in value the most — and what is a trade-in, exactly?
The graphics chip is the single biggest factor: a 2025 RTX 5080 or 5090 or a 2024 RTX 4090 pays dramatically more than an RTX 4060 or 5070 tier. After that, a Core Ultra 9 processor, more RAM (32GB or 64GB — remember it's soldered, so it can't be added later), a larger SSD, and the OLED panel all lift your final payout. Many people don't realize a trade-in here simply means selling your laptop to us directly for cash — no auction listings, no buyer haggling, no shipping risk. You get a locked online quote, ship it to us with a free, insured UPS label, and get paid. If you'd like to weigh a trade-in against selling privately, our guide on whether to trade in, resell, or donate a laptop. Because gaming laptops devalue somewhat quickly, selling sooner generally means more cash.
05 How do I wipe my data, and how do I get paid?
Before shipping, back up anything you want to keep to the cloud or an external drive, then sign out of your accounts — Microsoft, plus game launchers like Steam, Epic, EA App, Xbox, and Battle.net — and run a Windows factory reset. You don't need to remove the SSD yourself; our technicians perform a certified, multi-pass wipe on every incoming drive as standard. Full details are on our data erasure protocols page. Once your laptop arrives and passes functional testing, payment is approved within about two business days via PayPal, Venmo, Zelle, CashApp, or a mailed check. The prepaid shipping label is free and fully insured.
