DELL Precision 3551 laptop i7-10850H 16GB 500GB HDD Quadro P620 15.6" HD

Mobile workstation for CAD and ISV apps

The Dell Precision 3551 is a 15.6-inch mobile workstation built around a six-core Intel Core i7-10850H processor with a 5.10 GHz turbo frequency. It pairs 16 GB of memory with a 500 GB hard drive and a dedicated NVIDIA Quadro P620 graphics card carrying 2 GB of video memory. The 1366 x 768 HD non-touch display targets engineers and analysts who need certified driver stability for professional 3D applications.

Serviceable internals with limited storage speed

A bottom cover secured by captive screws gives direct access to the two SODIMM slots and the single 2.5-inch drive bay, so memory upgrades or a switch to a solid-state drive require only a Phillips screwdriver. The mechanical hard drive is the main bottleneck; cloning it to an SSD is straightforward but the laptop lacks an M.2 slot, so the 2.5-inch form factor remains the only internal storage option.

Sustained clocks held by dual-fan cooling

Under continuous multi-threaded load the i7-10850H maintains its 2.7 GHz base frequency while the dual-fan thermal solution keeps surface temperatures below throttle points. The Quadro P620 runs at full boost indefinitely for viewport rendering, though its 2 GB frame buffer limits scene complexity. Battery runtime drops sharply during heavy compute, so mains power is essential for long sessions.
