Next-level computing capabilities

The new Intel Core Ultra processor, combined with Intel vPro, delivers a secure hardware platform with extreme performance and optimized energy efficiency, ready for next-generation AI workloads and the versatile manageability capabilities businesses need to stay ahead.

Designed for efficiency

The new Intel Core Ultra processor is a next-generation hybrid architecture that delivers ultra-high-performance computing and durability with a three-level multiprocessing unit. Business users can manage complex workloads by sending the right tasks to the right engine at the right time with a CPU for lightweight, low-latency AI workloads, a GPU for media rendering and visual AI, and a dedicated AI engine, the NPU, for resilient AI offloading.

Saving time

The Copilot key on your device makes it easy to jumpstart your workflow, saving you time with quick access to the tools you need to start your workday.

Intelligent Collaboration

Users enjoy smoother collaboration with AI-accelerated features that make Windows Studio Effects even better, with features like smart cropping and noise reduction that don't impact overall system performance.

Exceptional battery life

The Latitude 5550 with an Intel Core Ultra processor delivers an average of 32% longer battery life than the previous generation.

Always ready to work with the camera

Look your best on conference calls with High Dynamic Range (HDR) multi-exposure capture. HDR captures multiple images simultaneously and blends them to accurately capture image detail in challenging lighting conditions, such as offices with windows and conference rooms.

Multi-level protection

The industry's most secure commercial PCs, featuring Dell SafeID, Dell SafeBIOS, fingerprint readers, a TPM chip, and a lock slot. The Latitude 5550 also features built-in security features like smart card readers, Control Vault 3+, privacy shutters, Windows Hello/IR camera, and intelligent security.

Innovations in Sustainable Development

  • The design uses a variety of sustainable materials, including post-consumer recycled plastic, ocean plastic, bio-based plastic and reclaimed carbon fibre.
  • The packaging is made from 100% recycled, renewable and recyclable materials, and the reusable packaging reduces waste.
  • EPEAT Gold and Climate+ registered.
