Dell Latitude 7480 vs 7490: Is the 8th Gen Upgrade Worth It?

TL;DR: The Dell Latitude 7490 is a worthwhile upgrade over the Latitude 7480 if you need better multitasking performance, particularly when comparing its 8th Gen Intel Core i5-8250U or i5-8350U processor with the 7480's 7th Gen dual-core processors. Both laptops offer a durable business-oriented design, upgradeable RAM, SSD storage, and practical connectivity. However, the 7490 is not automatically faster in every configuration, and its performance advantage depends on the processor, cooling condition, and overall hardware. For everyday browsing, office work, online classes, and basic productivity, the 7480 can still be a sensible budget choice. If you are buying a refurbished laptop for longer-term use, the 7490 is generally the better option, provided its condition and price justify the upgrade.

Dell Latitude 7480 vs 7490: Specifications Compared

The Dell Latitude 7480 and 7490 are 14-inch business laptops designed for professional use. They share a similar appearance, practical port selection, and upgrade-friendly hardware. The Latitude 7480 belongs to the 2017 generation, while the Latitude 7490 followed in 2018 with updated processor options.

The biggest difference is the processor. The Latitude 7480 was primarily offered with 6th and 7th Gen Intel Core processors, depending on configuration, while the Latitude 7490 introduced 8th Gen quad-core options alongside certain 7th Gen configurations. This distinction matters because the model number alone does not tell you how much performance a particular refurbished unit can deliver.

Other specifications vary by configuration, including display resolution, touchscreen support, storage, battery capacity, wireless connectivity, and security features. The following table provides a general comparison rather than suggesting that every unit has identical hardware.

Performance: How Much Faster Is The Latitude 7490?

8th Gen Quad-Core vs 7th Gen Dual-Core

The processor upgrade is the main reason to consider the Latitude 7490. A common Latitude 7480 configuration uses the Intel Core i5-7300U, a 7th Gen processor with two cores and four threads. The Latitude 7490 can be configured with the Core i5-8250U or i5-8350U, both of which have four cores and eight threads.

This additional processing capacity can make a noticeable difference when running several applications simultaneously. For example, keeping multiple browser tabs open while working in Excel, attending a video meeting, and switching between office applications is generally more comfortable on the quad-core configuration. Workloads that can use multiple processor cores also benefit from the extra capacity.

The performance improvement is workload-dependent, however. A faster processor does not automatically make every task twice as fast, and the 7490's cooling system, power settings, and condition affect its sustained performance. An independent review of the Latitude 7490 also noted thermal throttling under demanding workloads, so buyers should not assume that its processor can maintain peak performance indefinitely.

Everyday Productivity And Multitasking

For everyday work, both laptops can handle web browsing, word processing, spreadsheets, email, presentations, and online classes. With an SSD and sufficient RAM, even the older Latitude 7480 can feel responsive when running ordinary productivity applications.

The difference becomes more apparent when workloads grow heavier. Large spreadsheets, multiple browser windows, frequent application switching, and background tasks can put greater pressure on a dual-core processor. An 8th Gen quad-core Latitude 7490 generally has more room to handle these situations without becoming as easily overwhelmed.

Neither model is designed as a modern gaming laptop or a workstation for demanding 3D rendering. Their integrated graphics are suitable for everyday visuals, video playback, and basic graphics work, but they are not a substitute for a dedicated GPU. For most buyers, the 7490's stronger processor is the meaningful upgrade, not a dramatic improvement in graphics performance.

Design, Display, And Build Quality

Similar Business-Oriented Design

Dell kept the Latitude 7490's design relatively close to that of the 7480. Both have a professional appearance, a practical keyboard layout, and a chassis designed for everyday business use. Their similar designs make sense for refurbished buyers who prioritize usability and value over having the latest-looking laptop.

Both models are suitable for carrying between home, college, and the office, although the precise weight depends on the installed battery, display, and configuration. Their business-focused construction is a useful advantage when compared with inexpensive consumer laptops, but age and previous handling matter more than the original design when buying a used unit.

Check the hinges, keyboard, touchpad, screen, and chassis carefully before purchasing either model. A well-maintained Latitude 7480 can be a better buy than a heavily used 7490 with damaged hinges, a weak battery, or an unreliable charging port.

Display Quality And Connectivity

Both laptops were available with different 14-inch display configurations, including HD and Full HD options. A Full HD display with a resolution of 1920 x 1080 is generally preferable for office work because it provides more workspace for documents, spreadsheets, and browser windows. However, do not assume that every Latitude 7490 has a better screen than every 7480.

Connectivity is another area where the models are similar, but there is a practical difference. The Latitude 7480 has three USB-A ports, whereas the Latitude 7490 has two. Both can offer USB-C connectivity with DisplayPort, and Thunderbolt 3 is optional rather than guaranteed on every unit.

Before buying, confirm the exact ports and display specifications of the laptop being advertised. If you regularly connect a mouse, external drive, keyboard, and other accessories, the 7480's additional USB-A port may be more convenient. If external displays or docking stations are important, check the specific USB-C and Thunderbolt configuration.

RAM, Storage, And Upgrade Potential

Memory And SSD Options

Both the Latitude 7480 and 7490 support up to 32GB of DDR4 memory through two SO-DIMM slots, according to Dell's documentation. This is useful for buyers who want to extend a laptop's practical life without replacing the entire machine. The exact memory speed supported depends on the processor generation and configuration.

For basic productivity, 8GB of RAM may be sufficient, but 16GB is a more comfortable target for multitasking. Buyers who work with large spreadsheets, numerous browser tabs, or multiple applications may benefit from additional memory, provided their workloads and software support it.

Both models also support M.2 SSD storage, with available SATA and PCIe options depending on configuration. An SSD makes a substantial difference to everyday responsiveness compared with a traditional mechanical hard drive. Before upgrading, verify the installed drive type, available capacity, and compatibility rather than assuming every M.2 drive will offer the same performance.

Which Model Offers Better Long-Term Value?

The Latitude 7490 is generally the more attractive choice when the price difference is modest and both laptops are in similar condition. Its 8th Gen quad-core processor offers more headroom for multitasking, while the shared memory and SSD upgrade options help buyers improve performance without spending heavily on a replacement machine.

However, upgrades do not solve every limitation. Neither model has a modern dedicated graphics processor, and both come from an older hardware generation. Spending too much on RAM, storage, or repairs can make a newer refurbished laptop a better overall investment.

Compare the complete cost of ownership rather than the purchase price alone. Consider the cost of replacing the battery, upgrading the SSD, increasing RAM, or repairing a damaged component. A cheaper 7480 that needs several repairs may not offer better value than a clean, fully tested 7490.

Battery Life, Reliability, And Windows Compatibility

Battery Condition Matters More Than Original Claims

When these laptops were new, battery life depended on the display, battery capacity, processor, power settings, and workload. Today, both models are old enough that battery wear should be a major consideration when buying refurbished.

A battery that originally offered several hours of use may now provide considerably less runtime. Continuous video meetings, high screen brightness, background applications, and demanding workloads can reduce battery life further. Ask the seller about the battery's health and test the actual runtime where possible.

If you mainly use the laptop at a desk, a worn battery may be manageable if the laptop otherwise works well and the replacement cost is reasonable. For travel, college, or working away from power outlets, battery condition can be more important than the difference between the two processors.

Windows Support And Security

Windows compatibility deserves special attention when buying either model. Dell lists the Latitude 7490 among the computers tested for Windows 11, but buyers should verify the exact configuration and the requirements of the Windows version they intend to install. The Latitude 7480 is not included in Dell's published list of tested Windows 11 upgrade models.

Microsoft ended standard support for Windows 10 on October 14, 2025. This means users should not assume that a Windows 10 installation will continue receiving regular free security updates. Extended security options and their eligibility vary, so check Microsoft's current guidance before making a decision.

If long-term Windows compatibility is a priority, the Latitude 7490 is the more sensible choice of these two. However, neither laptop should be purchased solely on the assumption that its age will not matter. Check operating-system eligibility, firmware and driver availability, and the device's security configuration before committing.

Price And Buying Advice: Which Latitude Should You Choose?

When The Latitude 7480 Makes Sense

The Latitude 7480 remains worth considering if your budget is tight and your daily work consists mainly of browsing, documents, online classes, email, and basic spreadsheets. A clean unit with a healthy battery, SSD storage, and sufficient RAM can still serve as a practical everyday laptop.

It can also be attractive if you specifically need three USB-A ports or find a well-maintained unit at a substantial discount. For light workloads, the performance difference may not justify a large price premium, particularly if you do not regularly run several demanding applications at once.

Before purchasing, check the exact processor rather than relying on an i5 or i7 label alone. An older Core i7 is not automatically faster than a newer Core i5 in every workload. Also, consider the operating-system limitations and potential support costs when calculating the laptop's overall value.

When The Latitude 7490 Is The Better Buy

The Latitude 7490 is the stronger choice for buyers who want better multitasking performance and a little more processing headroom. An 8th Gen quad-core configuration is particularly appealing for office productivity, heavier spreadsheets, and running several applications simultaneously.

It is also the more practical option when Windows 11 compatibility is a priority, provided the exact unit meets the relevant requirements and has appropriate support. The model's additional processor capacity makes it a better starting point for someone who expects to use the laptop regularly rather than only for occasional light tasks.

Still, do not pay a premium for the model number alone. Confirm that the laptop actually has an 8th Gen processor, compare the installed RAM and SSD, inspect the screen, and test the keyboard, ports, webcam, Wi-Fi, charger, and battery. A refurbished laptop's actual condition can have a greater effect on value than its one-generation model difference.

Final Recommendation

The Dell Latitude 7490 is the better overall choice for most buyers comparing equivalent refurbished units, particularly when it comes with an 8th Gen Intel Core i5 quad-core processor. Its additional processing capacity makes multitasking more comfortable, and its Windows 11 compatibility prospects are better than those of the Latitude 7480. For students, office users, and professionals working with multiple applications, it offers a meaningful improvement without changing the basic business-laptop experience.

The Latitude 7480 still makes sense if it is significantly cheaper, well maintained, and intended for lighter workloads. Its SSD support, upgradeable RAM, Full HD display options, and practical connectivity remain useful. However, its older processor configurations and Windows compatibility limitations should be factored into the buying decision.

The final verdict: Choose the Latitude 7490 with an 8th Gen quad-core processor if the price difference is reasonable and the laptop passes a thorough inspection. Choose the Latitude 7480 only when the savings are substantial enough to justify its limitations. If both models are priced close to newer refurbished laptops, compare those alternatives before making a purchase.
