Features & Design

AI performance at your fingertips

A new way of computing: The new Intel Core Ultra processor delivers the next generation of hybrid architecture for supercharged computing with a battery that lasts. Thanks to a three tier multi-processing unit, business users can manage complex workloads by sending the right task to the right engine at the right time. A CPU manages lightweight low-latency AI tasks, a GPU manages media and visual AI rendering, and an NPU, a dedicated AI engine, manages sustained AI and AI offload.

AI-accelerated apps: An NPU helps apps run fast and smooth for efficient:

• Collaboration: Use up to 38% less power when utilizing AI-enhanced collaboration tools during Zoom calls.
• Creativity: 132% faster performance when running on-device AI photo editing on Adobe.
• Security: Detect malware with less than 1% CPU utilization using CrowdStrike.

Copilot Hardware Key: Effortlessly jumpstart your workflow with the Copilot Hardware Key on your device, saving you time by providing quick access to the tools you need to start your workday.

Exceptional battery life: The Latitude 5550 with Intel Core Ultra offers battery life up to 32% longer on average than the previous generation.

Intelligent collaboration: Users enjoy smoother collaboration with AI-boosts that make Windows Studio Effects even better, with features like smart framing and noise suppression that don’t impact overall system performance.

Always camera ready

Look your best on conference calls thanks to simultaneous multi-exposure High Dynamic Range (HDR). Available on configurations with an FHD or FHD IR camera, HDR technology takes several pictures simultaneously and blends them to accurately capture image detail in challenging lighting conditions, such as windowed offices and conference rooms.

Ultimate security to work from everywhere

Layered security: The industry's most secure commercial PCs offering Dell SafeID, Dell SafeBIOS, fingerprint readers, TPM chip and lock slot options. Latitude 5550 also features built-in security options such as contacted/contactless smart card readers, Control Vault 3+, privacy shutters, Windows Hello/IR camera and intelligent privacy.

Peace of mind: Intelligent privacy features from Dell Optimizer help keep sensitive data private. Onlooker Detection notifies you when someone is peering at your screen and will texturize your screen, and Look Away Dim knows when your focus is elsewhere and dims to further protect privacy and save battery life.

Be secure from first boot: Rigorous supply chain controls and optional Dell SafeSupply Chain solutions reduce the risk of product tampering. Verify the integrity of the device with Dell-unique Secured Component Verification. Additional supply chain assurance available with tamper-evident packaging and hard drive wipes.

Scalable productivity

Stay connected all day: Outstanding battery life and choice of long cycle life batteries up to 54WHr with ExpressCharge.

Visually stunning: Display options including FHD Touch as well as a battery saving and ComfortView Plus option to maximize performance and keep your eyes comfortable.

Fast response time: Improved performance with DDR5 upgradeable memory up to 64GB.

Crystal clear audio: Intelligent audio removes background noise on both ends of the call, while Dynamic Volume adjusts your PC speaker volume so you can hear your call clearly over unexpected noises.

Experience uncompromised connectivity

High-speed connections: Available Wi-Fi 6E and 4G/LTE ensure you’re always connected at the industry’s fastest speeds.

Productivity anywhere: Network Optimization joins the best available network, prioritizes conferencing apps and delivers fast data and video downloads with the world's first simultaneous multi-network connection.

Convenient connectivity: Quickly connect to peripherals with a broad range of ports including Thunderbolt 4.0 USB-C, HDMI 2.1 and USB-A.
