The Dell XPS 16 9640, released in early 2024, is Dell's flagship 16-inch premium laptop and the largest member of its redesigned XPS family — effectively the successor to the older XPS 15 and XPS 17. Built around Intel's Meteor Lake Core Ultra processors (Core Ultra Series 1) with a dedicated NPU for Copilot+ AI features, it pairs an all-aluminum CNC chassis in Platinum Silver or Graphite with a striking edge-to-edge “zero-lattice” keyboard, a capacitive touch function row, and a seamless haptic touchpad. Because the XPS 16 9640 was sold in a wide range of processor, graphics, memory, storage, and display combinations — including an optional 4K OLED touchscreen — your exact configuration decides its final resale price. If you're looking to sell your XPS 16, our Dell XPS trade-in page gives you a real cash offer — just pick your components using the tool above to see an instant quote for your exact device.

  • Intel Core Ultra 9 185H — 16 cores, 22 threads, up to 5.1 GHz

Memory (RAM)

  • LPDDR5x memory, offered in 16GB, 32GB, or 64GB
  • Soldered to the mainboard (onboard) and not upgradable — the capacity your laptop shipped with is permanent, so there's no way to add more later

Make sure you have the XPS 16 9640 (and not another XPS size)

Dell's redesigned XPS laptops all share the same look, so a quick 30-second check keeps you from picking the wrong product. The two cards below cover the model you're on this page for and the ones it's most often confused with.

This model — XPS 16 9640

The service label reads “XPS 16 9640” and the regulatory model is P123F. It has a 16.3-inch screen and is the only redesigned XPS offered with NVIDIA RTX graphics. If you see “9640” and a 16-inch display, you're in the right place.

Not this one — the smaller siblings & the rename

The XPS 13 9340 (13.4-inch) and XPS 14 9440 (14.5-inch) look nearly identical but are smaller. The older XPS 15 9530 and XPS 17 9730 are the previous generation this model replaced. And in 2025 Dell retired the XPS name, so a newer “Dell 16 Plus” or “Dell 16 Premium” is a different, later machine. Pick the matching model when you request a quote so your offer is accurate.

Where to find it: the model number and regulatory code are printed on the label on the bottom cover of the laptop. You can also type “System Information” into the Windows Start menu and read the System Model line, or check your Dell Service Tag on the same bottom label. Our guide to finding your Dell laptop model number walks through it step by step with pictures.

Display & audio

Display

A 16.3-inch InfinityEdge panel offered in two tiers. Most units ship with an FHD+ (1920 × 1200) non-touch IPS panel at up to 240Hz, 500 nits, 100% sRGB. Premium units carry a stunning 4K+ (3840 × 2400) OLED touchscreen at 400 nits with 100% DCI-P3 color and Dolby Vision — the OLED configuration typically fetches a higher trade-in value, so it's worth noting which one you have.

Audio

Quad-speaker system (dual woofers plus dual tweeters) tuned for a rich sound stage, with a 3.5mm combo jack featuring Waves Nx 3D audio with head tracking and dual-array microphones.

Ports & connectivity

A minimalist, all-USB-C port layout. Importantly, the XPS 16 has no built-in USB-A port and no built-in HDMI port — Dell includes a small USB-C-to-USB-A and USB-C-to-HDMI adapter in the box. The laptop charges over USB-C using the included adapter (up to 130 W).

Left Side
  • 2× Thunderbolt 4 (USB-C, 40 Gbps) (with DisplayPort and Power Delivery; used for charging)
Right Side
  • 1× USB-C (Thunderbolt 4 on Arc / RTX 4050 / RTX 4060 units; USB-C 3.2 Gen 2 on RTX 4070 units)
  • 1× microSD card reader
  • 1× 3.5mm headphone/microphone combo jack

Wi-Fi 6E or Wi-Fi 7 Bluetooth 5.4

Frequently asked questions

01 How do I confirm I have the Dell XPS 16 9640?
Flip the laptop over and read the label on the bottom cover: you're looking for “XPS 16 9640” and/or the regulatory model P123F, along with your Dell Service Tag. You can also type “System Information” into the Windows Start menu and check the System Model line. The easiest in-person tell is the 16.3-inch screen combined with the touch-sensitive function row above the keyboard and the borderless glass touchpad. If your label shows 9340 (XPS 13) or 9440 (XPS 14), see the next question. Our Dell model-number guide shows exactly where to look.
02 Is this the same as the XPS 14, the older XPS 15/17, or the newer Dell 16 Plus?
No, and it's an easy mix-up because they share a design language. The XPS 14 9440 (14.5-inch) and XPS 13 9340 (13.4-inch) are smaller members of the same 2024 family — check the screen size and the four-digit number. The XPS 15 9530 and XPS 17 9730 are the previous-generation models this one replaced. And in 2025 Dell retired the XPS branding entirely, so if your machine is labeled “Dell 16 Plus” or “Dell 16 Premium” rather than XPS, it's a newer product. As long as your label clearly reads XPS 16 9640, you're in the right place; if it says anything else, pick the matching model when you request your quote so your offer is accurate.
03 Can I sell an XPS 16 with wear, a cracked screen, or a worn battery?
Yes. We buy these in all working conditions. Whether yours is like-new, has scuffs on the aluminum, a battery that no longer holds much charge, keyboard or touch-row issues, or a cracked or unresponsive screen, just set the matching condition options above and your offer updates to a firm cash value. If you have the OLED touchscreen version, it helps to note whether the touch input still works — that lets us give you the most accurate quote.
04 How does the trade-in process work, and did you know this is an option?
Many people don't realize they can sell a premium laptop like this directly for cash instead of letting it sit in a drawer or dealing with buyers on a marketplace. Here's how it works with us: pick your configuration and condition above to get an instant quote, accept it, and we email you a free, fully insured prepaid shipping label. Box up your XPS 16, drop it off, and once it arrives and our team confirms the configuration and condition, your payment is approved — typically within about two business days. You can get paid by PayPal, Venmo, Zelle, or CashApp, or by a mailed physical check. If you'd like to read more first, our step-by-step guide to selling a used laptop online and our post on Dell laptop resale value walk through it. You can also browse other Dell laptops we buy or all PC laptops.
05 Should I wipe my data or remove the SSD before shipping?
We recommend backing up anything you want to keep to an external drive or the cloud, then signing out of your Microsoft account and doing a factory reset (Windows Settings → System → Recovery → Reset this PC) before you ship. You do not need to open the laptop or pull the M.2 SSD yourself — our team runs certified, multi-pass data sanitization on every drive we receive. You can read exactly how we handle it on our data erasure protocols page.
