DELL Precision 3551 laptop i7-10750H 32GB 1TB Quadro P620 15.6" HD

Precision 3551 mobile workstation

The Dell Precision 3551 is a 15.6-inch mobile workstation built around a six-core Intel Core i7-10750H processor that reaches 5.0 GHz turbo frequency. It ships with 32 GB of memory and a 1 TB SSD running Windows 10 Pro. A dedicated NVIDIA Quadro P620 graphics card with 2 GB memory drives the 1366 x 768 HD non-touch display. The carbon-fibre chassis weighs 1.89 kg and measures 359.10 mm wide by 236.25 mm deep.

Stepping up from integrated graphics

The Quadro P620 replaces integrated graphics for professionals who need certified drivers and stable viewport performance in CAD, DCC and GIS applications. The six-core CPU and 32 GB RAM combination removes the memory bottleneck common on 8 GB or 16 GB ultraportables when handling large assemblies or point-cloud data. Buyers staying with 1366 x 768 panels or requiring ISV certification for legacy workflows gain the most; users needing higher-resolution colour-critical screens or modern GPU compute features should look elsewhere.

Desk-ready connectivity

A single USB-C port with Thunderbolt supports docks and external GPUs, while HDMI and RJ-45 handle monitors and wired networks directly. USB 3.2 Gen 1 ports, one with PowerShare, and a full-size SD card reader cover peripherals and media offload without dongles. The wedge lock slot secures the device in shared spaces. An optional SIM slot enables mobile broadband for field work. Thunderbolt bandwidth and the 1 TB SSD free users from carrying external storage for active projects.
