Precision 5520 mobile workstation

The Dell Precision 5520 is a 15.4-inch mobile workstation built around an Intel Core i7-6820HQ quad-core processor running at 2.70 GHz. It ships with 32 GB of memory and a 512 GB NVMe drive. Windows 10 Pro 64-bit is pre-installed. The unit includes an AC power cord and battery.

Sustained workload behaviour

The quad-core CPU maintains its 2.70 GHz base frequency across extended render, compile or simulation tasks. With 32 GB of RAM, large datasets stay in memory without paging to the 512 GB NVMe volume. Thermal management in the 15.4-inch chassis is designed for continuous professional loads rather than short bursts.

Compatibility checks

Verify that your existing docking station or port replicator matches the Precision 5520 connector layout. Confirm that any external displays use interfaces supported by the laptop's native outputs. Ensure your software licences are transferable to a Windows 10 Pro 64-bit environment.

Questions about this item

How loud and hot does the i7-6820HQ get when the Precision 5520 runs all day?

The quad-core i7-6820HQ will spin the fans up under sustained load; expect noticeable but not extreme noise and warm surfaces during long sessions.

What must I already own to use the 512 GB NVMe drive and 32 GB of memory in this Precision 5520?

The laptop ships with the 512 GB NVMe drive and 32 GB of RAM already installed, plus an AC power cord and battery, so no extra parts are required to start working.

Will my older USB-A peripherals and external monitors work with the 15.4" Precision 5520?

The 5520 includes standard USB-A ports and video outputs, so existing keyboards, mice, drives and monitors connect directly without adapters.
