Dell Precision 3551 Touch delivers true workstation muscle in a slim 15-inch chassis, topped with a Full HD touch display for intuitive pinch-zoom, swipe, and on-screen annotation. A power-efficient 10ᵗʰ-generation Intel® Core™ or Xeon® processor, fast DDR4 (or ECC) memory, and NVMe solid-state storage slice through CAD models, data sets, and multitasking, while NVIDIA® Quadro® professional graphics keep 2D/3D workloads smooth and ISV-certified.

The MIL-STD-tested aluminum body travels easily yet hosts every pro-level port—Thunderbolt 3/USB-C, USB 3.2, HDMI, RJ-45, SD card reader, audio jack, plus an optional LTE SIM tray—so you can dock, present, and stay connected without dongles. ExpressCharge™ tops the long-life battery to about 80 % in an hour, and built-in safeguards—TPM 2.0, optional fingerprint reader, IR camera, SmartCard slot, and Dell SafeBIOS—lock down sensitive data. For engineers, designers, and analysts who need touch interaction, certified graphics power, and full-day endurance in a portable package, Precision 3551 Touch is a dependable, performance-driven companion.
