DELL Precision 3490 Mobile Workstation (2024)

The DELL Precision 3490 Mobile Workstation (2024) is Dell's 14-inch mobile workstation, built for engineers, 2D CAD users, developers and businesses that need a compact machine to carry every day. It runs on Intel Core Ultra U-series or H-series chips with a built-in NPU for AI processing, plus an optional NVIDIA RTX 500 Ada professional graphics card. Unlike many 14-inch business laptops, it still keeps HDMI, USB-A and Ethernet ports, so you rarely need to carry an adapter. Read on for the design, display, performance and connectivity, plus the trade-offs worth weighing before you choose a configuration.

Dell Precision 3490 Design: Compact and Light for Users on the Move

The Dell Precision 3490 has a gray chassis with squared-off lines, true to a business workstation. It weighs 1.40kg and measures 321.35mm wide and 212mm deep, with a thickness of 19.06mm at the front and 21.04mm at the rear, so it fits easily in a 14-inch backpack or padded sleeve.

At this weight, you can carry it all day between the office, the job site and meeting rooms without straining your shoulder. It is slightly thicker than 14-inch ultrabooks, but in return it has full-size ports such as HDMI, USB-A and RJ45. If you need a Dell laptop for technical work that is still easy to take along, the 14-inch Precision chassis is a sensible starting point.

Dell Precision 3490 (2024) Display: 14-Inch Full HD With a Touch Option

The Dell Precision 3490 (2024) uses a 14-inch Full HD 1920 x 1080 display with a 60Hz refresh rate. Dell offers three options: a 250-nit non-touch panel, a 400-nit non-touch panel and a 300-nit touch panel. All three include an EMZA Prox presence sensor, which lets the laptop detect when you sit down or step away from your desk.

The 400-nit version is worth choosing if you often work near windows, in lobbies or on job sites, while the 250-nit version is fine for rooms with steady lighting. Of the two configurations Hung Phat Laptop currently lists, the Core Ultra 5 125H model comes with the 250-nit panel and the Core Ultra 7 155H model comes with the 400-nit panel. Full HD is sharp enough for 2D CAD drawings, code and spreadsheets; if you need a higher resolution, you can connect an external monitor via HDMI 2.1 or Thunderbolt 4.

Precision 3490 Performance With Intel Core Ultra, an AI NPU, RTX 500 Ada Graphics and DDR5 RAM

The Precision 3490 offers six Intel Core Ultra Meteor Lake chip options, all with vPro support. The power-efficient U-series includes the Core Ultra 5 125U and Core Ultra 7 155U (12 cores, 14 threads). The H-series includes the Core Ultra 5 125H, Core Ultra 5 135H (14 cores, 18 threads), Core Ultra 7 155H and Core Ultra 7 165H (16 cores, 22 threads, up to 5.0GHz max boost). The two models on sale use the Core Ultra 5 125H at up to 4.5GHz and the Core Ultra 7 155H at up to 4.8GHz.

Source: average scores from Notebookcheck. Real-world results may vary with the power mode and ambient temperature; some chips have few test samples, so differences between closely matched chips are for reference only.

Based on the table above, the H-series chips score roughly 30% to 55% higher in multi-core tests than the U-series. The Core Ultra 5 125H handles heavy office work, 2D CAD, programming and photo editing. The Core Ultra 7 155H scores about 17% higher in multi-core, making it a good fit for compiling large projects, running simulations or editing video regularly. If you mostly work with documents, spreadsheets and online meetings, the U-series runs cooler and saves more battery.

Every Core Ultra chip has an Intel AI Boost NPU, which handles some AI tasks such as camera effects or noise cancellation on video calls using less power than running them on the CPU, depending on software support. Integrated graphics are Intel Arc, and the lineup adds an optional discrete NVIDIA RTX 500 Ada 4GB GDDR6 card for engineering software. The two models on sale at Hung Phat Laptop use Intel Arc integrated graphics.

Intel Arc integrated graphics are enough for 2D CAD, photo editing and light Full HD video editing. The RTX 500 Ada scores about 67% higher in Time Spy than the 8-core Arc, making it suitable for mid-level 3D modeling and engineering software that calls for a professional card. It is still an entry-level card, so if you render heavy 3D work regularly, consider larger workstations with higher-tier RTX Ada cards.

The DELL Precision 3490 Mobile Workstation (2024) uses DDR5 5600MHz RAM with 8GB, 16GB, 32GB and 64GB options; both models on sale have 16GB, enough for office multitasking, programming and CAD. The PCIe Gen4 M.2 SSD comes in 256GB, 512GB and 1TB options, and the models on sale use 512GB. As your projects grow, you can upgrade the RAM to 32GB and swap in a larger SSD to work more comfortably.

Keyboard, Speakers and Secure IR Webcam on the Dell Precision 14 3490

The keyboard on the Dell Precision 14 3490 follows the familiar layout of Dell's business lineup, without a separate numeric keypad, and the touchpad sits centered on the palm rest. If you enter a lot of numbers, you can add an external numeric keypad via a USB-A port.

The laptop has two 2W stereo speakers, 4W in total, with Waves MaxxAudio Pro 13.0 audio processing, clear enough for online meetings and casual music listening; when you need more volume, you can use headphones or external speakers through the audio port. The FHD 1080p 30fps RGB-IR webcam comes with dual microphones and an ambient light sensor, giving clearer video calls than the common 720p webcam.

The IR camera supports facial sign-in, along with Presence Detection for fast sign-in when you sit down and Intelligent Privacy to help protect the screen when you step away. The laptop ships with Windows 11 Pro, and combined with the vPro platform on every chip option, it makes remote management easy for corporate IT departments.

Dell Precision 3490 Ports and Battery: Thunderbolt 4, HDMI 2.1, RJ45 and a 54Wh Battery

The Dell Precision 3490 has 2 Thunderbolt 4 (40 Gbps) ports with DisplayPort, USB4 and Power Delivery charging, 1 USB 3.2 Gen 1 port with PowerShare, 1 USB 3.2 Gen 1 port, 1 HDMI 2.1 port, 1 RJ45 Ethernet port and 1 universal audio port. This port selection lets you connect external monitors, projectors, mice, USB drives and a wired network without an adapter.

Wireless connectivity comes from an Intel Wi-Fi 6/6E AX211 2x2 card with speeds up to 2400 Mbps, 2.4/5/6 GHz band support and Bluetooth 5. The RJ45 port is handy in offices or factories that use wired connections, while Thunderbolt 4 lets you attach a dock to drive multiple monitors over a single cable.

The 54Wh battery is moderate for a laptop with H-series chips, so when you run heavy workloads away from an outlet, runtime will be noticeably shorter than with office work. If battery life is your priority, choose a U-series chip, turn on power-saving mode and lower the screen brightness. The laptop charges through Thunderbolt 4, so you can carry a single USB-C charger with suitable wattage to travel light.

DELL Precision 3490 Mobile Workstation (2024) Overview and Review

The DELL Precision 3490 Mobile Workstation (2024) is a 14-inch workstation weighing 1.40kg, with Intel Core Ultra chips featuring an NPU, DDR5 5600MHz RAM and the full set of ports a business environment needs. It suits engineers, 2D CAD users, developers and technical staff who need a compact, secure and easy-to-manage machine.

The points to consider are that the display is only Full HD at 60Hz and the 250-nit version is a bit dim in bright places, so choose the 400-nit version or connect an external monitor when needed. The 54Wh battery is moderate, and a U-series chip will help the laptop last longer. The RTX 500 Ada card is only entry-level for 3D graphics.
