Built for mobile professionals
The Dell Latitude 5550 is a 15.6-inch laptop powered by an Intel Core Ultra 7 155U processor with 12 cores and 14 threads. It ships with 32GB of DDR5 memory and a 256GB PCIe NVMe SSD. Windows 11 Pro is pre-installed for immediate deployment in managed environments.
Gray chassis with Thunderbolt 4 and RJ-45
The IPS display runs at 1920 x 1080 resolution and 60Hz without touch input. Two Thunderbolt 4 ports handle charging, video and data through a single connector. A full-size HDMI port, two USB 3.0 Type-A ports, an SD card reader and a wired RJ-45 jack cover legacy peripherals. Wi-Fi 6E AX211 and Bluetooth 5.3 provide wireless connectivity.
Replaces older 15-inch fleet devices
The jump is worth it when teams need DDR5 bandwidth and Thunderbolt 4 dock simplicity in a 14.09 x 9.19 x 0.90 inch form factor. Integrated Intel Graphics limits the machine to productivity workloads and light media. Buyers who need discrete GPU performance or a larger storage allocation should look elsewhere.

Questions about this item
What practical limits does the Thunderbolt 4 interface on this Latitude 5550 apply?
The two Thunderbolt 4 ports handle data, video output and power delivery through USB-C connectors.
What physical space does the 2230 form-factor SSD require inside the chassis?
The 256 GB drive uses the shorter 2230 M.2 length, so the slot must accept that size.
How is the DDR5 memory installed and what step is often missed?
The 32 GB DDR5 SO-DIMMs seat in the internal slots; the clips must click fully home on both sides.
