Dell Latitude 5420 Models and Configurations

One reason enterprises love Latitudes is the breadth of customization available. The Latitude 5420 models offer numerous combinations of components to spec the perfect laptop.


The latest 11th generation Intel Core power the 5420 series:

  • Core i5-1135G7 – up to 4.2GHz, 4 cores, 8MB cache
  • Core i5-1145G7 – up to 4.4GHz, 4 cores, 8MB cache
  • Core i7-1185G7 – up to 4.8GHz, 4 cores, 12MB cache

The Core i5 offers a good balance of performance for everyday tasks. The Core i7 boosts speed for demanding applications or multitasking. All support Intel vPro for enterprise management.


Available RAM configurations:

  • 8GB DDR4-3200
  • 16GB DDR4-3200
  • 32GB DDR4-3200
  • 64GB DDR4-3200

Maxing out RAM helps for heavy workloads. Up to 64GB lets you juggle dozens of apps and browser tabs without slowdowns.


Fast PCIe NVMe solid state drives deliver quick boot times and data access:

  • 128GB SSD
  • 256GB SSD
  • 512GB SSD
  • 1TB SSD
  • 2TB SSD

Larger drives up to 2TB provide ample space for files, media, virtual machines, and more.


Three display options are offered:

  • 14-inch 1920×1080 IPS, anti-glare
  • 14-inch 1920×1080 IPS, 400 nit outdoor viewable
  • 14-inch 1920×1080 IPS Touchscreen

The standard display suits most indoor use. Choose the ultra-bright 400 nit panel for outdoor visibility. Or get the touchscreen for tablet-like interaction.

This variety of component choices spans from affordable base configs to high-end spec‘d out workstations. Enterprises can customize 5420s tailored to each employee‘s needs.

Design – Durability Meets Portability

Despite its 14-inch screen size, the Latitude 5420 weighs just 3.03 pounds and measures 0.78 inches thick. It strikes a nice balance of screen real estate vs. compact portability.

The smooth, squared-off chassis is all business. The lid, base, and interior sport a durable dark gray magnesium alloy construction with carbon fiber accents. Black rubber trims along the edges absorb impacts from drops.

Dell subjected the 5420 to 19 MIL-STD-810H durability tests including shocks, vibrations, exposure to extreme temperatures and humidity, and environmental factors like sand and dust. Short of hazardous work sites, it‘s built to survive everyday business use abuse.

Carbon fiber and magnesium alloy chassis provide durability

But most importantly, the Latitude 5420 retains the enterprise-friendly serviceability of previous generations. Just one screw allows removing the bottom plate to access components for upgrades and repairs. Critical for minimizing downtime when issues arise.

The functional, business-like aesthetic may not have the wow factor of a premium ultrabook. But form follows function, and the 5420 delivers where it matters most – with reliable construction.

Display Analysis

One of the few nitpicks reviewers had on the 5420 was its display. While good, it‘s not groundbreaking compared to consumer laptops. Let‘s analyze the key display metrics:


  • Up to 400 nits / Up to 250 nits standard


  • 1920 x 1080 (166 PPI)

Aspect Ratio

  • 16:9


  • IPS LCD, anti-glare

Color Gamut

  • 45% NTSC

Contrast Ratio

  • 700:1

The 400 nit max brightness and 1080p resolution ensure good outdoor and indoor visibility. Contract ratio could be higher but color accuracy tested well. The anti-glare IPS screen reduces eye fatigue.

Still, while it handles documents and media fine, creative pros may want higher color gamuts and a 4K resolution. Compared to OLED displays on premium flagships, the 5420 screen looks average. But it gets the job done for most business use.

Top-Notch Productivity Performance

Performance is where the Latitude 5420 truly excels compared to consumer notebooks. The potent 11th Gen Intel Core processors, generous RAM allotments, and fast NVMe SSD storage make short work of intensive business workloads.

CPU benchmarks show the Latitude 5420 competes with top-tier ultrabooks:

CPU Benchmarks

Processor Cinebench R20 Single core Cinebench R20 Multi core
Core i5-1135G7 572 3314
Core i5-1145G7 591 3335
Core i7-1185G7 604 4447

With performance rivalling premium ultrabooks, the 5420 blazes through tasks like financial modeling, statistical analysis, data visualization, CAD software, video conferencing, and more. The generous DDR4-3200 RAM lets you juggle dozens of apps without slowdown.

Storage speeds are snappy thanks to PCIe NVMe solid state drives:

SSD Read/Write Speeds

SSD Read Speed Write Speed
128GB SSD 2.1 GB/s 1.3 GB/s
256GB SSD 2.2 GB/s 1.9 GB/s
512GB SSD 3.1 GB/s 2.2 GB/s
1TB SSD 3.3 GB/s 3.0 GB/s
2TB SSD 3.5 GB/s 3.3 GB/s

As a bonus, chipset-based Intel AES-NI encryption ensures your sensitive corporate data is secure.

For intensive number crunching, data analysis, financial work, engineering programs, video production, and other demanding business uses, the Latitude 5420 delivers workstation-class power in a portable package.

Ample Ports for Desktop-Like Connectivity

The Latitude 5420 packs an impressive range of ports into its slim frame. Let‘s look at what‘s included:

Left Side

  • 2x Thunderbolt 4
  • 1x USB 3.2 Gen 1
  • 1x microSD card reader
  • 1x HDMI 2.0
  • 1x 3.5mm headphone jack

Right Side

  • 1x USB 3.2 Gen 1

  • 68Whr

Battery Life (measured with FHD screen)

  • Up to 12 hours light use
  • Up to 21 hours idle use

Recharge Time

  • ExpressCharge can reach 80% in an hour

With nearly 21 hours of runtime on a charge, you can make it through marathon workdays away from an outlet. The quick recharge support lets you top up during short breaks.

Battery life does take a hit with intensive workloads, dropping to 5-6 hours for heavy productivity use. Overall though, the 5420 provides enough portable endurance for most business travel needs.

Built for Enterprise IT Needs

What really differentiates the Latitude line are the enterprise-specific features like:

  • Intel vPro – Enables remote management capabilities like hardware-level authentication and WLAN/LAN control.
