DELL Precision 3550 laptop i5-10310U 8GB 256GB 15.6" HD

Mobile workstation for professionals

The Dell Precision 3550 is a 15.6 inch mobile workstation running Windows 10 Pro. It targets engineers and analysts who need a portable system for CAD, simulation or data workloads. The carbon-fibre chassis keeps weight to 1.86 kg while meeting MIL-STD durability standards. Buyers who want a thin-and-light ultrabook or a dedicated gaming GPU should look elsewhere.

Quad-core CPU with 4.40 GHz turbo

The Intel Core i5-10310U provides four cores and a maximum turbo frequency of 4.40 GHz. That clock speed is the single figure that determines whether the laptop can finish your compile or render jobs within an acceptable time window. The 8 GB of memory and 256 GB SSD are soldered or limited to one slot, so capacity cannot be expanded later.

Sustained performance under load

Under continuous multi-threaded load the processor settles near its 1.7 GHz base frequency while the integrated graphics share system memory. Thermal throttling appears after several minutes of full utilisation, so long batch jobs run slower than the peak turbo figure suggests. The 1366 x 768 HD panel draws little power, helping battery life during lighter tasks.
