The Dell Precision 3520 offers strong performance and long-lasting battery life, but suffers from a dim screen and a flexy keyboard.

Dell Precision 3520 (i7-7820HQ, M620M) Workstation Review

good complement of physical ports ; pretty good Full HD IPS display ; chassis designed for every-day use ; good input devices ; run times are decent even with the small battery ; good performance

Dell Precision 3520 Review and Ratings


It's not cheap (though it's cheaper than other mobile workstations aimed at crunching huge datasets or complex 3D rendering projects), but Dell's Precision 3520 is a solid choice for illustrators, computer-aided design (CAD) professionals, and others...

Good value ; Excellent battery life ; No-nonsense design

After fully recharging the laptop, we set up the machine in power-save mode (as opposed to balanced or high-performance mode) and make a few other battery-conserving tweaks in preparation for our unplugged video rundown test. In this test, we loop a...
