Five Dell laptops are compared here: the XPS 14 Premium, the Inspiron 14 7440 2-in-1, the Latitude 7450, the Precision 3490, and the Dell Pro 16 PC16250. Amazon lists Thunderbolt 4 on each one, and gives a port count for only two: three on the XPS and two on the Precision. The Inspiron text reads “Thunderbolt 4 / USB Type-C.”
Amazon says the seller resealed the Latitude, the Precision, and the Dell Pro 16 to upgrade memory or the SSD, so those sizes describe the seller’s configuration, not Dell’s. Every detail below comes from the Amazon listings.

Dell Laptops With Thunderbolt 4 Compared
The table compares the best fit, screen, Thunderbolt 4 port count, Ethernet, and memory and SSD for each laptop. A Thunderbolt port starts a connection, and the dock, cable, and monitors need their own compatibility check.

Buying Guide
Pick the screen and size first
The XPS 14 has the sharpest screen listed here. Amazon lists 3200 x 2000 on its 14.5-inch OLED touchscreen, against 1920 x 1200 on the Inspiron, Latitude, and Dell Pro 16 and 1920 x 1080 on the Precision.
The Dell Pro 16 has the largest screen. Amazon lists a 16-inch anti-glare panel, while the Latitude and Precision list 14 inches. The Inspiron lists a touchscreen with a 360-degree hinge, and the XPS listing mentions no hinge.
Read the Thunderbolt 4 text for each laptop
Only two listings give a port count. Amazon lists three Thunderbolt 4 ports on the XPS 14 and two on the Precision 3490. The Latitude and Dell Pro 16 list Thunderbolt 4 with no count, and the Inspiron reads “Thunderbolt 4 / USB Type-C.”
A port label starts the connection check. Displays also depend on the dock, cable, monitor inputs, resolution, and refresh rate. Amazon lists up to three external monitors at 4K and 60Hz without a dock for the Latitude, Precision, and Dell Pro 16, so confirm the full connection path before counting on that figure.
Check Ethernet and the other built-in ports
Ethernet is listed on two laptops. Amazon lists it on the Precision 3490 and Dell Pro 16, and lists none for the XPS, Inspiron, or Latitude. If wired networking is a daily need, a built-in port can replace an adapter or a dock.
HDMI is listed on four. Amazon lists HDMI on the Inspiron, Latitude, Precision, and Dell Pro 16, and none on the XPS. The Inspiron also lists an SD card reader, which no other listing mentions.
Separate the seller’s upgrades from Dell’s configuration
Three listings say the seller resealed the laptop. The Latitude’s SSD, the Precision’s memory and SSD, and the Dell Pro 16’s memory and SSD are seller upgrades, so their sizes are not Dell’s. The XPS and Inspiron listings do not mention an upgrade.
The warranty differs by listing. The Latitude has a three-year seller warranty on the SSD and a one-year Dell warranty on the rest. The Precision has a three-year seller warranty on its upgraded parts and Dell support until March 2027, and the Dell Pro 16 has a one-year seller warranty. Check the return terms before ordering.
FAQ
Which Dell lists the most Thunderbolt 4 ports?
The XPS 14 Premium, with three. Amazon lists two on the Precision 3490, and the Inspiron, Latitude, and Dell Pro 16 listings give no count.
Three ports do not remove other compatibility checks. Confirm the devices, dock, cable types, and displays that will share those connections before treating the count as a full desk plan.
Is the Inspiron or the Latitude better for work?
Choose the Inspiron for a touchscreen with a 360-degree hinge and an SD card reader, or the Latitude for a 14-inch anti-glare screen, Wi-Fi 7, and a QHD infrared camera. Amazon lists Windows 11 Home on the Inspiron and Windows 11 Pro on the Latitude.
Neither listing includes Ethernet. The Latitude’s SSD is a seller upgrade, so compare the SSD size and warranty before you order.
Does the Precision 3490 work as a dock laptop?
Amazon lists two Thunderbolt 4 ports, Ethernet, and HDMI on the Precision 3490. The Ethernet and HDMI ports connect to a wired network and a monitor without an adapter.
Amazon’s multi-monitor statement is not a dock certification. Check the software you run, the dock, the monitors, and the cables before you build a desk around it.
Are seller-upgraded Dell laptops a problem?
Not necessarily, but the seller’s disclosure changes how the sizes should be read. Amazon says the Latitude, the Precision, and the Dell Pro 16 were resealed to upgrade the SSD or memory.
Read the warranty and return terms as closely as the port list. A larger SSD or memory total helps only if the seller’s coverage meets your needs.
Can these Dell laptops run several monitors?
Amazon lists up to three external monitors at 4K and 60Hz without a dock for the Latitude, Precision, and Dell Pro 16, through HDMI and Thunderbolt 4 or USB-C. It states no monitor count for the XPS or the Inspiron.
The usable setup depends on all the connected equipment. Check monitor resolution, refresh rate, cable, and dock support before you expect the listed figure.
Bottom Line
Choose XPS 14 Premium for three listed Thunderbolt 4 ports and an OLED touchscreen, Latitude 7450 for a 14-inch anti-glare business screen, or Precision 3490 for a mobile workstation with Ethernet. With a seller-upgraded laptop, confirm the memory, SSD, warranty, and return terms before buying.
The configuration you order, not the model name, is the buying decision.
