This extended support means the 5420 will remain compatible with the latest software features and security patches for more years.
• Physical Durability: Both models are built with business-grade durability in mind. The Latitude 5420 features a carbon fiber and magnesium reinforced chassis, while the Latitude 7490 utilizes a magnesium alloy chassis, often with an optional carbon-fiber lid. Both are designed to withstand daily professional use, with the 7490 having passed MIL-STD A10G tests in some configurations, indicating a high level of resilience.
• Repairability and Upgradability: Both laptops offer good repairability, allowing for relatively easy access to internal components like RAM and storage. The Latitude 5420 has two RAM slots and an M.2 slot for SSDs, making upgrades straightforward. Similarly, the Latitude 7490 is noted for being easy to service, with accessible RAM and SSD slots, contributing to its practical lifespan.

The performance capabilities of these two Latitude models reflect their respective generations, with the newer 5420 offering more contemporary processing power and efficiency. Both provide solid foundations for business and general computing tasks.

• Processing Power: The Latitude 5420 is equipped with 11th Generation Intel Core processors, which deliver enhanced processing power and improved efficiency for demanding applications and multitasking. The Latitude 7490, featuring 8th Generation Intel Core processors, provides reliable performance for everyday office tasks and moderate workloads.
• Memory and Storage: The Latitude 5420 supports up to 64 GB of DDR4 RAM at 3200 MHz, offering greater capacity and speed for intensive multitasking. The Latitude 7490 typically supports up to 32 GB of DDR4 RAM at 2400 MHz. Both models utilize fast M.2 PCIe NVMe SSD storage options, ensuring quick boot times and responsive application loading.
• Graphics Performance: The Latitude 5420 benefits from integrated Intel Iris Xe Graphics in many configurations, providing a notable improvement in graphical performance over the Intel UHD Graphics 620 found in the Latitude 7490. This makes the 5420 better suited for tasks involving light photo editing or more graphically intensive applications.

The visual experience on these laptops is designed for productivity, with both offering Full HD displays, though the newer model introduces some advancements in display technology.

• Display Technology and Resolution: Both the Latitude 5420 and 7490 typically feature 14-inch Full HD (1920 x 1080) IPS anti-glare displays, which are suitable for extended work sessions by reducing reflections. The 5420 consistently offers an IPS panel, while some earlier 7490 configurations might have included lower-resolution TN panels.
• Brightness and Color Reproduction: The Latitude 5420 generally offers brightness levels around 250-311 nits, with color coverage around 53% of the sRGB gamut. The Latitude 7490's display typically ranges from 277-300 nits, with sRGB coverage varying from 77% to 124% depending on the specific panel. Both displays are generally considered adequate for office work and indoor use, though neither is designed for professional color-critical tasks.
• Refresh Rate and Viewing Experience: Both models feature a standard 60 Hz refresh rate, which is typical for business laptops and provides a smooth experience for general computing. The IPS technology in both ensures wide viewing angles, making them suitable for collaborative work or presentations. Neither display uses Pulse-Width Modulation (PWM) for brightness control, which can be beneficial for users sensitive to screen flickering.

For communication and media consumption, both Latitude laptops include essential audio and visual components, with the 5420 offering some minor enhancements.

• Camera System: Both the Latitude 5420 and 7490 are equipped with a 720p HD webcam, suitable for video conferencing and online meetings. The Latitude 5420 often includes an integrated webcam shutter for privacy and some configurations offer an IR camera for facial recognition via Windows Hello. The 7490 also had optional IR camera configurations.
• Microphone Quality: The Latitude 5420 features dual-array microphones with Realtek Waves MaxxAudio Pro, designed to provide clear audio capture and noise cancellation for calls. The Latitude 7490 also includes dual microphones, offering a similar experience for voice communication.
• Speaker Output: Both laptops come with stereo speakers (2W x 2), often enhanced with Realtek Waves MaxxAudio Pro for improved sound quality. User feedback for both models suggests that while the speakers are adequate for general media consumption and video calls, they may not offer a rich audio experience, with some users noting the 7490's speakers can be underwhelming.
