How this Mobile Workstation performs in practical terms
Thunderbolt 3 ports provide high-speed data and power delivery
The Precision 5520 includes Thunderbolt 3, which allows you to connect high-speed peripherals and external displays using a single cable.
Because Thunderbolt 3 supports Power Delivery, you can charge the laptop and transmit data simultaneously over the same port. This reduces cable clutter when you need to connect multiple high-bandwidth devices to your luggable workstation.
32 GB of memory supports heavy multitasking and professional apps
The Precision 5520 supports a maximum of 32 GB of memory, which provides the overhead needed for heavy multitasking and running demanding professional applications. This amount of memory allows you to keep multiple large projects open at once without the system slowing down as you switch between tasks.
For users who find 32 GB insufficient for specific workflows like large-scale 3D rendering or running multiple virtual machines, the system may hit a hardware limit. If your workflow requires more than 32 GB, you should verify your specific software requirements before choosing this model.
Infinity Edge display maximizes workspace on a 15.6-inch screen
The 15.6-inch Infinity Edge display minimizes the borders around the screen to maximize the visible workspace. This design allows for a larger viewing area within a smaller chassis footprint, which is beneficial when you need to see more of your timeline or CAD layout on a portable device.
The Infinity Edge design helps keep the overall chassis size at 14 inches, improving the portability of the luggable workstation. This trade-off between screen size and physical dimensions allows you to maintain a large display while keeping the device manageable for travel.
Where the Precision 5520 Sits Among the Alternatives
The Precision 5520 provides a 15.6-inch Infinity Edge display, which removes the traditional bezel border to maximize the visible screen area for a mobile workstation.
