Dell‘s Latitude 5420: A Trusted Ally for Today‘s Mobile Professional

As someone constantly on the move juggling responsibilities across locations, you need technology designed for non-stop productivity that keeps business flowing smoothly regardless of circumstances. For over 20 years, Dell‘s Latitude laptops have armed professionals across enterprises and industries with precisely that through a formula combining performance, durability, and flexibility tailored for life away from a desk.

The latest Latitude 5420 packs the series‘ most potent combination of processing muscle, resilient construction, and practical features yet into a highly portable 14-inch form starting around 3 lbs. This guide provides a comprehensive look at exactly how the 5420 stands ready to become your most trusted on-the-go ally.

Built On Two Decades of Commercial Laptop Experience

Before diving into the specifics around the Latitude 5420 itself, it helps to understand the lineage that led to its creation. Back in early 2008, Dell launched the very first Latitude notebook after noticing traditional consumer oriented laptops struggled with the unique demands of commercial use – things like logging endless highway mileage or operating non-stop every weekday.

Companies needed more durable and stable platforms purpose built to thrive under such intense real-world circumstances. The Latitude brand was born out of that need for true enterprise-class hardware.

Fast forward over 20 generations and many workhorse small business laptop releases later, these principles of durability, flexibility, security and productivity still guide Latitude development today. The 5420 represents the culmination of leveraging direct customer feedback to constantly refine the blueprint.

Latitude 5420 Overview and Key Specifications

The 5420 launched in early 2021 as a successor to the Latitude 5400 series originally introduced in 2019. Situated as a mainstream corporate laptop, it‘s neither the cheapest nor most premium offering from Dell. Let‘s examine how the vital statistics measure up:

Next we‘ll break down all the flexible configuration options and key hardware components enabling the 5420 to stay resilient across locations.

Customizable Components – Configure to Your Exact Scenario

While employees at large companies typically use standard builds mandated by IT, small businesses often require more tailored setups aligning budget to unique needs. Dell understands no two professionals identical hardware preferences.

That‘s why the Latitude 5420 grants extensive component selection spanning various performance profiles and price points.

Processing Power

Let‘s start with the brains – processors based on Intel‘s 11th generation Core architecture. Shoppers choose between two models:

  • Core i5-1135G7 – quad core, 8 threads up to 4.2 GHz speeds
  • Core i7-1145G7 – same core/thread layout at higher 4.4 GHz clocks

For perspective, this compares reasonably well against competitor flagship ultraportables like the Lenovo ThinkPad X1 Carbon Gen 9:

|| Dell Latitude 5420 | Lenovo ThinkPad X1 Carbon Gen 9|
| CPU | Core i7-1145G7 | Core i7-1185G7 |
| Cores/Threads | 4/8 | 4/8 |
| Cache | 8MB | 12MB |
| Base Clock | 2.4GHz | 1.8GHz |
| Max Turbo Clock | 4.4GHz | 4.8GHz |

The Latitude trails slightly in cache capacity and turbo velocity. But its aggressive boost clock at lower base speeds actually provides snappier response during short bursts of activity compared to the ThinkPad. Both handle office productivity without issue. For more intensive tasks, the ThinkPad‘s extra thermal headroom helps longer workloads. But overall processing grunt should satisfy most mobile professionals.

Memory and Responsiveness

While original specifications included up to 32GB of RAM, newer configurations support 64GB using two SODIMM DDR4 slots clocked at 3200 MHz. This allows effortless juggling of statistical programs, 40+ Chrome tabs, video calls, virtualized environments and other demanding workflows. Integrated Thunderbolt 4 enables seamless experience docking with external accessories too.

HHD bottlenecks don‘t hamper the experience either thanks to speedy solid state drives communicating over PCIe lanes. The M.2 slot supports capacities up to 2TB, providing substantial local storage. Self-encrypting models enable instant safe data wiping as well – crucial for client privacy. During real world use, applications launch swiftly with barely any perceivable lag navigating the Windows UI.

Graphics and Media

You‘ll have to look towards mobile workstations for dedicated graphics. But the integrated Intel Iris Xe solution here actually drives up to 4K displays and light gaming reasonably well. Benchmarks show the chip scoring over 200 frames per second in Rocket League at 1080p low settings, and around 30 fps in modern titles at high detail.

So media professionals on the move can smoothly edit high resolution footage from drones, perform 3D walkthroughs of real estate listings, or review architectural plans. Of course, concentrated 3D/CAD applications still benefit from NVIDIA‘s specialized drivers and additional compute resources.

Designed for Life Beyond the Office

Let‘s address the elephant in the room – those memories of traditional business-oriented laptops built like bricks. Fantastic for durability, but a nightmare lugging around while fighting gate changes and racing towards connections. Fortunately Latitude engineers understand road life, significantly trimming thickness and weight over the years without substantially impacting resilience.

Materials and Construction

Consider the exterior – a lightweight magnesium alloy lid and bottom cover surrounded by rigid plastic absorbing drops and bumps. It‘s not the tank-like indestructibility of earlier Latitude models, but a prudent balance limiting bulk while still easily meeting MIL-STD-810H durability criteria. Dell relies on a unique process of elastic shaping injection molding to reinforce structural stability points prone to cracking while retaining flexibility elsewhere.

So in practice, the 5420 withstands short drops onto carpet or being knocked off tables onto flooring without issue. The strongly anchored hinges open and shut smoothly even after thousands of cycles. And the spill resistant coating shrugs off up to 60cc of water exposure over interfaces, giving you time to save work. through these little touches add up to a reassuringly sturdy laptop that holds up reliably.

Input Experience

Expect a similarly understated but purposeful focus enhancing interaction through backlit, worldwide accessible keyboard sporting 19mm key spacing and 1.5mm travel depth cushioning presses. It forgoes flashy thin keys for comfortable all day typing.

You‘ll also appreciate the roomy precision touchpad providing a smooth glide recognizing taps and multi-touch gestures consistently. It makes manipulating detailed spreadsheets or graphic editing substantially easier. And dedicated volume controls eliminate fumbling to find adjustments mid-meeting.


The Latitude 5420 thankfully retains legacy interfaces still essential in the business world, like an RJ-45 ethernet jack delivering wired speeds up to gigabit when WiFi proves unreliable. You also get an HDMI 2.0 port supporting external 4K displays, and a microSD slot supplementing the onboard M.2 storage.

Wireless connectivity handles the latest standards as well with WiFi 6 compatibility enabling better performance in congested environments compared to older generations. Low energy Bluetooth 5.2 suits accessories like headsets and smartphones. Some configs even ship with LTE support through microSIM slots if you truly need connectivity anywhere.

Visual Collaboration from Anywhere

Video calls represent a substantial chunk of daily grind for modern professionals. The Latitude 5420 ensures you appear crisp clear through premium collaboration hardware. Let‘s explore why it excels for remote meetings.


It all starts with the 14-inch 1920 x 1080 IPS based panel sharp enough for split screening research and documents alongside live video. 400 nits max brightness proves sufficient fighting average ambient glare, and anti-reflective finish further cuts distracting reflections under bright lighting. Dell also shifted to low voltage signaling for reduced power draw while maintaining image quality.

You can angle the screen nearly 180 degrees to accommodate impromptu group review sessions too. Just keep realistic expectations – this remains a mainstream corporate display prioritizing well-rounded experience over vibrance. But it brings out the intended contrast and shades accurately across applications.


Of course crisp imagery requires more than the display alone, which is why Dell opts for a higher quality 1080p webcam rather than the typical grainy 720p shooters most competitors integrate. And it makes a substantial difference capturing accurate facial tones without excessive noise.

Coupled with beamforming mics that hone in on speech, the Latitude 5420 presents you loud and clear without echoes. Background noise cancellation tech eliminates distracting interference as well. The privacy shutter conveniently shuts off video when not in use, sliding open easily when meetings start.

Audio Quality

You‘ll actually enjoy surprisingly decent audio output from the bottom firing speakers as well thanks to Waves MaxxAudio Pro software tuning and smart amps preventing distortion at higher volumes. Sound projects loudly enough to fill smaller conference rooms. Just don‘t expect heavy bass or surround effects. But for clearer conversations, no complaints.

Balancing Performance, Portability and Battery Life

Latitudes emphasize responsiveness across common tasks over outright benchmark dominance or extreme portability. The 5420 reviewed here keeps power draw at reasonable levels for sustained operation off its 63Wh battery without throttling speeds too aggressively. Standby time stretches past two weeks on a full charge.

You can expect around 12 hours of continuous use depending on workload based on PCMark testing. Video playback at medium brightness lands over 15 hours. In real world mixed use alternating between web browsing, Office docs, quick photo editing sessions, and the occasional compilation job pushes 6-7 hours.

That roughly matches competitors like the Lenovo ThinkPad X1 Carbon and HP Elite Dragonfly. Lighter notebooks eke out an hour or two longer runtimes by further limiting horsepower. But combined with the 5420‘s petite 65W USB Type-C charger fully refreshing in just over an hour, you stay productive on the move no matter how hectic things get.
