Dell Precision 5490 vs Precision 5690
Dell Precision 5490
Dell Precision 5690
The Dell Precision 5490 and Precision 5690 are the two members of Dell's premium thin-and-light mobile workstation family, and the split between them is mostly size and headroom. The 5490 is the 14-inch model built for engineers and creators who move constantly and want ISV-certified workstation power in an ultraportable chassis. The 5690 is the 16-inch model that trades some portability for a larger canvas, a higher GPU and thermal ceiling, and more room to expand memory and storage. Neither is the "better" workstation. The right pick comes down to display size, how heavy your workloads run, and how much time the machine spends in a bag versus on a desk. Uniqcli configures and ships both, so this page frames where each one earns its place.
Side by side
| Dell Precision 5490 | Dell Precision 5690 | |
|---|---|---|
| Positioning / tier | 14-inch premium mobile workstation. The ultraportable of the Precision 5000 line, built for maximum mobility with real ISV-certified workstation credentials. | 16-inch premium mobile workstation. The larger, higher-ceiling sibling for users who want more screen, more GPU, and more thermal headroom in the same design language. |
| Form factor & display | Compact 14-inch InfinityEdge display in a small, light chassis. Easy to carry all day and work from tight spaces like coach seats and field sites. | Roomier 16-inch InfinityEdge display with more usable canvas for timelines, CAD viewports, and multi-panel layouts. A larger, heavier footprint overall. |
| Portability | Lighter and thinner. The clear choice when the machine lives in a backpack and travels between sites, client offices, and labs. | Still thin for its class, but bigger and heavier. Better suited to a primary desk with periodic travel than to constant daily transport. |
| Graphics ceiling | Supports NVIDIA RTX Ada-generation professional laptop graphics tuned to a 14-inch thermal envelope. Strong for a machine this size, with a lower ceiling than the 16-inch. | Accommodates higher-tier NVIDIA RTX Ada professional laptop graphics. The pick when GPU-bound work like rendering, simulation, and larger 3D scenes is the bottleneck. |
| CPU & thermal headroom | Intel Core Ultra mobile processors in a compact cooling design. Excellent sustained performance for its size, with less thermal room under long full-load runs. | Same Intel Core Ultra class with a larger cooling solution, so it can hold higher sustained clocks under prolonged heavy compute and rendering. |
| Memory & storage capacity | Generous configurable memory and fast NVMe SSD options, sized for a 14-inch workstation. Ample for most engineering and creative workflows. | Higher memory and storage ceilings for very large assemblies, high-resolution media, big datasets, and local VM or container work. |
| Display options | High-quality panel choices including sharp high-resolution and touch options, scaled to 14 inches. Great for a portable color-accurate second-to-none travel display. | Larger premium panel options, including high-resolution and OLED-class choices, that give creators and CAD users more pixels and working area. |
| Battery & all-day use | Tuned for portability and long unplugged sessions, so it holds up well through travel days and meetings away from power. | Larger battery to feed a bigger display and higher-end components. Strong runtime, though heavier workloads and the 16-inch panel draw more. |
| Target user / workload | Field engineers, consultants, and creators who need certified workstation performance in the lightest possible package. | CAD, media, data science, and simulation users who want more screen and more sustained horsepower and can accept added size and weight. |

Choose Dell Precision 5490 when
Portability is the priority. If the workstation travels every day between clients, sites, and labs, the 14-inch 5490 is the one people actually carry. It delivers ISV-certified Precision performance, Intel Core Ultra processors, and RTX Ada professional graphics in an ultraportable chassis that stays comfortable in a bag and holds up through long unplugged days. Reach for it for field engineering, on-site consulting, real-time collaboration, and creative work that has to be mobile first. Most CAD, design, and analysis workflows run beautifully here, as long as you are not consistently GPU-bound or memory-bound at the top of the range. When you want the lightest true mobile workstation Dell makes without dropping to a thin-and-light that is not certified, the 5490 is the answer. Build a config at /quote.
Choose Dell Precision 5690 when
The workload sets the ceiling, not the bag. If rendering, simulation, large CAD assemblies, high-resolution video, or sizable local datasets are the bottleneck, the 16-inch 5690 gives you the higher GPU tier, more sustained thermal headroom, a larger memory and storage ceiling, and a bigger display to work on. It is the better desk-anchored machine that still travels when needed, and the roomier 16-inch canvas pays off for anyone living in multi-panel layouts or timelines all day. Pick it when the extra size and weight are a fair trade for finishing heavy jobs faster and configuring more headroom into a single system. Spec the memory, GPU, and storage that match the workload on a /bom and we will price it as configured.
Both are excellent Precision mobile workstations, and the decision is refreshingly simple. Lead with the 5490 when mobility wins: daily travel, field work, and users who value the lightest certified workstation Dell offers. Lead with the 5690 when the work is heavier and the machine spends more time at a desk: GPU-bound rendering and simulation, large assemblies, high-resolution media, and anyone who wants more screen and more headroom to configure. A useful shortcut is to qualify on three things. How often does it move, does the workload push the GPU or memory to the top of the range, and does the user want a 14-inch or 16-inch canvas? If it moves constantly and stays inside mainstream workstation needs, the 5490 fits. If it is desk-anchored or routinely maxes out compute and graphics, the 5690 is worth the size. Many fleets standardize on both, the 5490 for road warriors and the 5690 for power users. Uniqcli sells and configures either, so send the workload and we will scope the right one.

Talk to a specialistFrequently asked
What is the core difference between the Precision 5490 and 5690?
Size and headroom. The 5490 is the 14-inch ultraportable built for maximum mobility, while the 5690 is the 16-inch model with a larger display, a higher GPU and thermal ceiling, and more room to expand memory and storage. Both are ISV-certified Precision mobile workstations with Intel Core Ultra processors and NVIDIA RTX Ada professional graphics.
Can the Precision 5490 handle serious CAD and creative work?
Yes. The 5490 is a fully certified workstation and runs the large majority of CAD, design, engineering, and creative workflows well. The main reasons to step up to the 5690 are consistently GPU-bound or memory-bound jobs like heavy rendering and simulation, very large assemblies, or a preference for the 16-inch display. Send your applications to /quote and we will confirm the right fit.
Which one is better for travel?
The 5490. Its 14-inch chassis is lighter and thinner, so it is the easier machine to carry every day and work from tight spaces. The 5690 still travels, but its larger size and weight make it better suited to a primary desk with occasional trips.
Do I have to match exact specs before ordering?
No. Tell us the workload, the applications, and how the machine will be used, and we will recommend the model, GPU, memory, storage, and display. Start at /quote, or if you already know the configuration, build a line-item /bom and we will price it as configured.
Are these available for federal and public-sector buyers?
Yes. Precision mobile workstations can be configured for TAA-compliant, standards-driven procurement, and Uniqcli supports federal, state, local, and education buyers alongside commercial accounts. Reach us through /contact or send requirements to /quote and we will align the configuration and contract vehicle to your needs.
