Dell Precision 5520 is a slim 15.6-inch mobile workstation combining sleek design with pro-grade performance. Its near-borderless InfinityEdge Full HD or optional UHD display delivers immersive, color-accurate visuals, while 7ᵗʰ/8ᵗʰ-generation Intel® Core™ i5/i7 or Xeon® processors, up to 32 GB DDR4 RAM, and fast PCIe NVMe SSD storage power through CAD, 3D rendering, and multitasking with ease. A spill-resistant backlit keyboard, precision touchpad, and a versatile port selection—including dual Thunderbolt 3/USB-C, a USB-A port, HDMI (via adapter), and an SD card reader—keep you connected without bulk.

Engineered in a CNC-machined aluminum and carbon-fiber chassis just under 1.8 kg, the Precision 5520 meets enterprise durability standards and offers optional NVIDIA® Quadro® graphics for ISV-certified acceleration. Enterprise-grade security—TPM 2.0, optional fingerprint reader, Smart Card slot, and Dell SafeBIOS—safeguards sensitive data, while ExpressCharge™ refuels the battery to 80 % in about an hour. With its combination of portability, workstation-class power, and long battery life, the Precision 5520 is an ideal companion for engineers, designers, and power users on the move.
