When it comes to selecting a business laptop, reliability, performance, and build quality are paramount. The Dell Latitude series has long been a favorite among professionals, thanks to its reputation for solid construction and dependable performance. Two well-regarded models in the Latitude line—albeit from different generations—are the Dell Latitude E6420 and the Dell Latitude E7490. Despite both carrying the Latitude name, these laptops cater to slightly different use cases and possess distinct hardware configurations that can influence your selection depending on your needs.
This article offers an in-depth comparison of the Dell Latitude E6420 and E7490, examining aspects such as design, performance, features, and overall value. By the end, you will have a clear understanding of which laptop better suits your needs—whether you favor legacy reliability or modern capabilities.
Design and Build Quality
Dell Latitude E6420: Released in 2011, the E6420 boasts a tough and professional design. It features Dell’s Tri-Metal chassis construction, which includes a brushed aluminum lid and a magnesium alloy base. Built to withstand drops, shocks, and other physical stresses, the E6420 is designed with field usage in mind. However, this rugged build comes at a cost—it is both thick and heavy by today’s standards, weighing around 4.5 to 5 pounds depending on configuration.
Dell Latitude E7490: In stark contrast, the E7490, released in 2018, represents a new generation of Dell’s enterprise laptops with a focus on mobility. The system sports a slim profile, updated aesthetics, and a significantly lighter footprint, weighing only about 2.9 pounds. The chassis is composed primarily of carbon fiber and magnesium alloy, giving it a sleek yet sturdy design suitable for modern office environments.
Display and Visual Experience
E6420: The E6420 features a 14-inch anti-glare LED-backlit display, typically offering a resolution of 1366×768 pixels, although a 1600×900 option was available for some configurations. While adequate for basic office tasks, the screen lacks modern sharpness and color accuracy, making it less ideal for visually intensive work such as graphic design or media consumption.
E7490: The E7490 steps up significantly in display quality. It also has a 14-inch screen but comes with much higher resolution options, including Full HD (1920×1080). The display supports In-Plane Switching (IPS) technology, which enhances color reproduction and allows for wider viewing angles. Some configurations even offer touch support, adding an element of interactivity absent in the older model.
Performance and Hardware
Latitude E6420: At the heart of the E6420 is a 2nd generation Intel Core i5 or i7 processor. While reliable for basic multitasking, office software, and light data processing, this CPU is severely dated by today’s standards. Additionally, the standard hard drive speeds (5400 RPM or 7200 RPM) and DDR3 RAM limit performance, especially for users accustomed to more responsive systems.
Latitude E7490: The E7490 is a powerhouse in comparison. Equipped with 8th generation Intel Core i5 or i7 CPUs, solid-state drives (SSD) as standard, and DDR4 RAM, this laptop is designed for multitasking and performance-heavy workloads. Boot times are near-instant, and software runs much more smoothly compared to the legacy E6420. Its integrated Intel UHD 620 graphics also offers substantially better media handling.
Ports and Connectivity
E6420: Surprisingly, the E6420 holds its own in this category. It offers a mix of older and still-useful ports including VGA, HDMI, Ethernet, USB 2.0 and USB 3.0 ports, an ExpressCard slot, and even an optical drive. This makes it ideal for environments where legacy ports are still required.
E7490: The E7490 offers a more modern port selection, with USB 3.1 ports, HDMI, a USB-C port with DisplayPort capability, and an optional Thunderbolt 3 port. However, it lacks legacy options like VGA or optical drive, which could be a limitation in some scenarios. That said, its wireless capabilities are significantly better with support for newer Wi-Fi standards (including Wi-Fi 6 in some configurations) and Bluetooth 5.0.
Keyboard and Input
E6420: The E6420 features a traditional keyboard layout with deep key travel, which many users find satisfying for typing. It includes a pointing stick along with the touchpad and has physical mouse buttons, appealing to users who deal heavily in precise pointer navigation.
E7490: The E7490 opts for a chiclet-style keyboard with backlighting and a more modern design. While offering comfortable typing, the reduced key travel may not satisfy all traditionalists. The glass-precision touchpad, however, offers smoother navigation and gesture support, which will likely appeal to modern users who rely on multitouch for workplace productivity.
Battery Life and Efficiency
E6420: Due to its older architecture and less efficient components, the E6420 generally delivers around 4 to 6 hours of battery life under normal usage, depending on the battery size and workload. While this may suffice for stationary office use, it poses limitations for modern mobile professionals.
E7490: Battery efficiency is one of the major strengths of the E7490. Thanks to a newer chipset, better power management, and SSDs, this model regularly achieves 8–12 hours of uptime on a single charge. This makes it ideal for frequent travelers and remote workers who require full-day performance without being tethered to an outlet.
Software Support and Security Features
The technological gap between the E6420 and the E7490 also affects software compatibility and security.
- E6420: Designed for Windows 7, this laptop does support Windows 10, but performance is limited. Security features are dated, with TPM 1.2 and older BIOS configurations. Many modern enterprise security standards are unsupported or require manual configuration.
- E7490: Built with Windows 10 in mind, this system also qualifies for Windows 11 in some configurations. It features TPM 2.0, SecureBoot, and optional hardware-level security modules like fingerprint readers and smart card readers—made for today’s security-conscious workplace.
Pricing and Availability
E6420: This older model is quite affordable on the used market, with refurbished units often available for under $200. However, the low price can be offset by increasing maintenance or upgradation costs (such as replacing the HDD with an SSD for a performance boost).
E7490: As a more modern device, the E7490 holds a higher resale and used-market value, typically between $300–$600 depending on the condition and configuration. While the upfront investment is greater, the long-term value proposition is more favorable due to better performance and longevity.
Conclusion: Which One Should You Choose?
The decision between the Dell Latitude E6420 and E7490 boils down to your specific use case:
- Choose the E6420 if you need a rugged, legacy-compatible machine, perhaps for industrial environments or applications that rely on older ports or pre-Windows 10 compatibility. It’s also an excellent budget choice for those with very basic computing needs.
- Choose the E7490 if mobility, performance, and modern software compatibility are essential to your workflow. It’s far better suited to today’s multitasking world and provides a better long-term return on investment.
In a rapidly evolving tech landscape, the E7490 stands out as the more future-proof option, while the E6420 remains a reliable, albeit dated, workhorse for niche requirements.
