Mobile workstation for technical workflows

The Dell Precision 3551 is a 15.6 inch mobile workstation built around an Intel Core i7-10750H six-core processor with a 5.0 GHz turbo frequency. It ships with 8 GB of memory, a 256 GB SSD and a dedicated NVIDIA Quadro P620 graphics card with 2 GB of video memory. Windows 10 Pro comes pre-installed on the carbon fibre chassis.

Six-core CPU with 5.0 GHz turbo under load

The i7-10750H runs at a 2.6 GHz base frequency and can reach 5.0 GHz with Turbo Boost when thermal headroom allows. The Quadro P620 provides certified drivers for professional 3D and CAD applications rather than consumer gaming workloads. Sustained performance will depend on the cooling solution inside the wedge-profile chassis.

Carbon fibre build with Thunderbolt and wired LAN

The carbon fibre lid and base keep weight to 1.89 kg while maintaining rigidity for daily transport. Connectivity includes HDMI, RJ-45, a headphone jack, a memory card reader, USB 3.2 Gen 1 ports with PowerShare, a USB-C port with Thunderbolt and a wedge-shaped lock slot. The 1366 x 768 non-touch display offers basic HD clarity.

Questions about this item

How loud and hot does the i7-10750H six-core processor get during sustained workloads?

The 2.6 GHz base clock and 5.0 GHz turbo on the six-core i7-10750H will generate noticeable heat and fan noise under continuous load; the 0.88-inch front and 0.98-inch rear chassis heights limit airflow compared to thicker workstations.

Which peripherals or docks must I already own to use the USB-C Thunderbolt and HDMI ports?

You need Thunderbolt-compatible docks or devices for the USB-C port and an HDMI cable for external displays; the laptop also provides USB 3.2 Gen 1 Type-A ports for legacy accessories.

Will the Quadro P620 2GB GPU drive my older 1366 x 768 external monitor without scaling issues?

Yes, the Quadro P620 supports the native 1366 x 768 resolution over HDMI, so an older monitor at that resolution will display pixel-for-pixel without scaling artefacts.
