Mobile workstation with six-core processor

The Dell Precision 3551 is a 15.6-inch mobile workstation built around an Intel Core i7-10750H six-core processor reaching 5.0 GHz turbo frequency. It ships with 64GB of memory and a 1TB SSD running Windows 10 Pro. The NVIDIA Quadro P620 dedicated graphics card with 2GB memory drives the 1366 x 768 HD non-touch display. A carbon fibre chassis keeps weight to 1.89 kg.

Connectivity and expansion for desk or field

Two USB 3.2 Gen 1 ports and one USB-C port with Thunderbolt handle peripherals and external displays. HDMI and RJ-45 ports add wired video and network links. A memory card reader and optional SIM slot support removable media and mobile broadband. The wedge-shaped lock slot secures the device physically. PowerShare on one USB port charges accessories while the system sleeps.

Suited for CAD and ISV workflows on the move

Engineers and analysts who need certified Quadro drivers and large memory capacity for 3D modelling or simulation will find the configuration ready. Buyers who require a higher resolution panel, touch input or an integrated webcam should consider other models. The HD screen and 2GB GPU frame buffer limit detailed visual work and multi-monitor scaling. Users needing Thunderbolt 4 or newer CPU architectures should look elsewhere.

Questions about this item

How long will the i7-10750H sustain its 5.0 GHz turbo before thermal limits throttle it?

The six-core i7-10750H runs at 2.6 GHz base and can hit 5.0 GHz turbo, but the 15.6" chassis with .88" front height limits sustained turbo duration under heavy load.

What are the fan noise and surface temperatures when the Quadro P620 and CPU run flat-out for hours?

With a 4.16 lb weight and .98" rear profile, the cooling system manages the 620 GPU and 45 W processor, yet extended all-day loads will raise keyboard deck temperatures and spin fans audibly.

Which dock or adapter do I need to drive two external monitors from the single HDMI and USB-C Thunderbolt ports?

The HDMI and USB-C Thunderbolt outputs each support one external display, so a Thunderbolt dock or USB-C MST hub is required for dual-monitor setups.
