Dell Latitude 7455 14"

Manufacturer: Dell

The Dell Latitude 7455 14″ is a productivity-oriented laptop built around a 14-inch IPS touchscreen running at 2560 x 1600 resolution with a pixel density of 215 ppi and 400 nits of typical brightness. It supports up to three external displays and includes 3D facial recognition alongside a backlit keyboard, stereo speakers, a 3.5 mm audio jack, and a front camera capable of 720p video at 30 fps.

Under the hood, the machine runs on a 12-core processor clocked at 3.4 GHz with a turbo frequency of 4 GHz, paired with 16GB of DDR5 RAM across eight memory channels delivering up to 135 GB/s of bandwidth, with support for up to 64GB. Storage is handled by a 1TB NVMe SSD over PCIe 4.0. The Adreno X1 integrated GPU features 1536 shading units and a boost clock of 1200 MHz. Connectivity includes two USB 4 40Gbps ports, one USB-A 3.2 Gen 1 port, Bluetooth 5.4, Wi-Fi 7, and optional 5G and LTE support, all powered by a 54 Wh battery.

Pros
  • Supports USB 4 at 40Gbps on two ports, enabling fast data transfer and versatile peripheral connectivity
  • Wi-Fi 7 support ensures access to the latest wireless speeds, with backward compatibility down to Wi-Fi 4
  • 3D facial recognition provides a convenient and secure biometric login method without relying on a fingerprint scanner
  • The 2560 x 1600 IPS touchscreen delivers a sharp 215 ppi image with touch input support across a 14-inch panel
  • Integrated 5G and LTE connectivity allows mobile internet access without relying on external adapters
  • Memory bandwidth reaches 135 GB/s across eight channels, supporting demanding multitasking workloads with up to 64GB of DDR5 RAM
Cons
  • No HDMI, DisplayPort, or any wired video output ports are available, limiting direct display connections without adapters
  • The display lacks an anti-reflection coating, which may cause visibility issues in bright or outdoor environments
  • Refresh rate is limited to 60Hz, which restricts smooth rendering for fast-moving content
  • A single microphone is included, which may be insufficient for clear audio capture in noisy environments
  • The 54 Wh battery capacity is modest for a productivity laptop used throughout the day
  • No RJ45 port is present, making wired ethernet connections dependent on an external adapter
Who is this for?

This laptop is well-suited to business professionals and enterprise users who require a capable, portable workstation for everyday productivity tasks. The 12-core processor with DDR5 RAM, an NVMe SSD, and a sharp 2560 x 1600 touchscreen make it a practical fit for users handling document-heavy workflows, multitasking, and data-intensive applications. Built-in 5G and LTE support make it a strong choice for workers who are frequently on the move and need reliable connectivity without depending on fixed networks. The inclusion of 3D facial recognition, TrustZone, and NX bit support also makes it appropriate for environments with strict security and authentication requirements.

Who is this NOT for?

Users looking for a laptop suited to gaming or GPU-intensive creative work will find this machine lacking, as the integrated Adreno X1 graphics do not support ray tracing or DLSS, and the display is capped at a 60Hz refresh rate, which is unsuitable for smooth fast-paced visuals. The absence of any wired video output — including HDMI and DisplayPort — makes it a poor fit for users who need to connect directly to external monitors or projectors without carrying adapters. Additionally, with a single microphone and 720p front camera, it is not well-matched for professionals whose work revolves around high-quality video conferencing or content recording.
