Mobile workstation for precision tasks

The Dell Precision 5520 combines an Intel Core i7-7820HQ processor at 2.9GHz with 16GB DDR4 memory and a 512GB SSD. A 15.6-inch 3840 x 2160 display and NVIDIA Quadro M1200 graphics target engineers, designers and analysts who need colour-accurate visuals and certified driver stability in a portable chassis. Windows 10 Pro is pre-installed.

Connectivity and expansion in a compact frame

Four USB ports and one HDMI output handle peripherals and external monitors without a dock. Integrated 802.11ac Wi-Fi and Bluetooth support wireless accessories and network access. The 512GB SSD leaves the 2.5-inch bay free for a second drive if additional local storage is required. No optical drive is fitted.

Thermals, acoustics and power in daily use

The Quadro M1200 discrete GPU shares the cooling solution with the quad-core CPU, so sustained loads raise fan speed noticeably but remain within typical mobile-workstation limits. Light office work keeps the system near silent. The included AC adapter supplies enough power for full performance and battery charging simultaneously.

Questions about this item

How long can the i7-7820HQ sustain its 2.9GHz speed before thermal throttling reduces performance?

The quad-core processor runs at 2.9GHz base frequency; sustained loads will trigger thermal management that lowers clocks to keep temperatures within the 5520 chassis limits.

What are the fan noise and surface temperatures like when the Quadro M1200 and CPU run at full load for hours?

Under continuous load the cooling system ramps fan speed to dissipate heat from both the i7-7820HQ and M1200 GPU, producing audible airflow and warm palm-rest areas typical for a 15.6" mobile workstation.

Which peripherals or docks must I already own to connect external displays to the HDMI port and four USB ports?

The laptop provides one HDMI output and four USB ports, so any monitor with HDMI input and standard USB peripherals will work without additional adapters.
