The Lenovo Legion 9 is Lenovo's flagship gaming laptop line, spanning three generations from 2023 through 2026. It was built for players and creators who wanted desktop-class graphics in a chassis engineered around a liquid-metal cooling loop, not a compromise. Depending on the model year you'll find it as the Legion 9 16IRX8, Legion 9 16IRX9, or the newer 18-inch Legion 9 18IAX10. These machines carried a premium price at launch and they hold value well on the resale market, since the combination of high-end NVIDIA graphics and a Mini-LED display is still hard to find elsewhere. Pick your processor, graphics card, and condition above for an instant cash offer. If you want the mechanics of the process first, you can see how the process works, and if this isn't your only machine to move, take a look at how to sell your gaming laptop with us.

Confirm you have the Legion 9

The fastest way to confirm your exact model is through Windows itself. Press the Windows key + R, type "dxdiag," and press Enter to see the system model and installed graphics card. You can also open Lenovo Vantage, which reports the model name and serial number directly. The model number is also printed on a sticker on the underside of the chassis, though on some units this wears off with handling.

Legion 9 16IRX8 (83AG)

  • 2023 model year
  • 16-inch chassis
  • Intel Core i9 13th Gen processor
  • NVIDIA RTX 4090 graphics

Legion 9 16IRX9 (83G0)

  • 2024 model year
  • 16-inch chassis
  • Intel Core i9 14th Gen processor
  • NVIDIA RTX 4080 or RTX 4090 graphics

Legion 9 18IAX10 (83EY)

  • 2026 model year
  • 18-inch chassis, larger than earlier Legion 9 models
  • Intel Core Ultra 9 Series 2 processor
  • NVIDIA RTX 5080 or RTX 5090 graphics

Prefer a visual check? The 18IAX10 is noticeably larger and heavier than the two 16-inch models that came before it, so a side-by-side with a ruler settles that question fast. All three generations share the same signature look: a full-width vent across the rear hinge and a Legion "L" logo on the lid. If you're still unsure, our model finder and our Lenovo model number guide walk through it step by step.

Core hardware configurations

Processor

  • Intel Core i9 13th Gen (16IRX8)
  • Intel Core i9 14th Gen (16IRX9)
  • Intel Core Ultra 9 Series 2 (18IAX10)

Graphics

  • NVIDIA RTX 4080
  • NVIDIA RTX 4090
  • NVIDIA RTX 5080
  • NVIDIA RTX 5090

The graphics tier moves resale value more than any other spec on this laptop. An RTX 5090 or RTX 4090 configuration commands a materially stronger offer than the entry-level card in the same generation.

Memory

  • LPDDR5X, soldered to the motherboard
  • Not user-upgradable after purchase

Storage

  • PCIe Gen4 M.2 2280 solid-state storage
  • Dual M.2 slots on most configurations, user-accessible

Display & audio

Display

Legion 9 models use a Mini-LED panel with a high refresh rate, tuned for both fast-motion gaming and color-accurate creative work. Panel size follows the chassis: 16 inches on the 16IRX8 and 16IRX9, 18 inches on the 18IAX10.

Audio

Harman Kardon-tuned speakers ship across the line, positioned to fire upward from the deck for clearer sound during gaming sessions.

Security

A fingerprint reader built into the power button and an IR camera for Windows Hello facial login are standard across the Legion 9 lineup.

Ports & connectivity

The Legion 9 keeps a full-size port selection despite its thin-for-the-hardware chassis, which matters if you're pairing it with external monitors or wired peripherals.

Battery, build & more

Battery

A large battery is standard across the line, but like most high-wattage gaming laptops, unplugged runtime under gaming load is short. Plan on running it tethered to power for demanding sessions.

Build

The chassis is built around Legion's liquid-metal thermal system, which lets the CPU and GPU run at higher sustained power than a typical vapor-chamber design of the same thickness.

Software

Ships with Windows and Lenovo Vantage preinstalled, which handles driver updates, fan curve profiles, and battery conservation settings.

Known issues

Soldered memory means the RAM tier you buy is the RAM tier you keep, so check that spec carefully before buying used. The 18-inch 18IAX10 is also noticeably heavier than earlier generations, which matters if portability is part of your decision.

Frequently asked questions

01 How do I find the model number / exact configuration?
Run dxdiag from the Run dialog (Windows key + R) or open Lenovo Vantage, both of which show the exact model and installed graphics card. The model number is also printed on the underside sticker, though it can wear off on older units. If neither is legible, our model finder walks through alternate ways to confirm what you have, including checking the original box or purchase receipt if you still have it.
02 How do I tell it apart from the Legion 7i?
The Legion 9 is Lenovo's flagship tier, distinguished by its liquid-metal cooling system and Mini-LED display, features the Legion 7i does not carry. The Legion 7i uses a more conventional vapor-chamber cooling setup and a standard IPS or OLED panel depending on year. If dxdiag or Lenovo Vantage reports "Legion 9" in the system model name, you have the flagship version covered on this page.
03 Can I sell it with damage (cracked screen, weak battery, won't turn on)?
Yes. Select the condition that matches the laptop above and the quote adjusts accordingly, whether the issue is a cracked display, a battery that no longer holds charge, or a unit that won't power on at all. Before shipping, remove any Microsoft account link and suspend BitLocker encryption if it's enabled, since a locked drive can't be tested or wiped by our team.
04 What raises the trade-in value the most?
The graphics card tier matters most, since an RTX 5090 or RTX 4090 configuration is worth meaningfully more than the entry-level card in the same generation. Beyond that, having the original charger and box helps, along with a display free of dead pixels or Mini-LED blooming issues and a chassis free of dents from the liquid-cooling vents on the rear hinge. Since memory is soldered, you can't add RAM to raise the offer, but a clean, fully functional unit in its original condition brings the strongest number.
05 How do I erase it and remove my accounts, and how do I get paid?
Go to Settings → System → Recovery → Reset this PC and choose "Remove everything" to wipe the drive. Before that, sign out of and remove the laptop from your Microsoft account under Settings → Accounts, and if BitLocker is on, suspend or disable it so the drive isn't locked when we test it. Once the reset finishes, package the laptop with its charger if you have it. Shipping is free and insured, and payment goes out after testing by PayPal, Venmo, Zelle, CashApp, or check. Full steps, including how to handle edge cases, are in our data erasure protocols.
