Dell Inspiron 16 5640 (2025) 16"

Manufacturer: Dell

The Dell Inspiron 16 5640 (2025) is a 16-inch productivity laptop that covers everyday computing needs with a generous set of hardware specifications. Its 16-inch display runs at a 1920 x 1200 resolution with touch support and anti-reflection coating, making it comfortable to use across a range of lighting conditions. The machine includes a backlit keyboard, a fingerprint scanner for convenient authentication, and even ships with a stylus included, which pairs naturally with its touchscreen.

On the performance side, the Inspiron 16 5640 is equipped with 64GB of DDR5 RAM — expandable up to 96GB — alongside a 2TB NVMe SSD running on a PCIe 4 interface. The processor uses big.LITTLE architecture, with a turbo clock speed reaching 5.4 GHz across 12 threads, and achieves a Geekbench 6 multi-core score of 7404. Graphics are handled by the Intel Iris Xe G7 96EU integrated GPU with a turbo frequency of 1300 MHz, capable of driving up to four external displays. Connectivity includes Wi-Fi 6, Bluetooth 5.3, one USB 3.2 Gen 2 Type-C port, two USB 3.2 Gen 1 Type-A ports, HDMI 1.4, and an external memory card slot.

Pros
  • 64GB of DDR5 RAM with support for up to 96GB gives substantial headroom for memory-intensive workloads
  • The 2TB NVMe SSD on a PCIe 4 interface provides fast storage with plenty of space for large files and projects
  • A stylus is included in the box, making the touchscreen immediately usable for note-taking or sketching without extra accessories
  • The 16-inch display includes both touch support and an anti-reflection coating, improving usability in varied lighting conditions
  • Wi-Fi 6 support ensures faster and more reliable wireless connectivity on compatible networks
  • The fingerprint scanner offers a convenient and quick biometric login method
Cons
  • No Thunderbolt, USB 4, or DisplayPort ports limits high-speed peripheral and external display options
  • HDMI output is limited to version 1.4, which restricts maximum resolution and refresh rate on external monitors
  • Only a single microphone is built in, which may be limiting for video calls or recording in noisy environments
  • There is no RJ45 ethernet port, so wired network connections require an additional adapter
  • The integrated GPU does not support ray tracing or DLSS, narrowing its suitability for graphically demanding tasks
  • Sleep-and-charge is not available on any USB port, so connected devices cannot charge when the laptop is off or asleep
Who is this for?

This laptop suits users who need a capable productivity machine for memory-intensive and multitasking workloads, given its 64GB of DDR5 RAM expandable to 96GB and a fast 2TB NVMe SSD. The included stylus and touchscreen make it a practical fit for professionals who regularly annotate documents, sketch out ideas, or work with digital ink. Its support for up to four simultaneous displays also makes it a reasonable choice for users who rely on expanded multi-monitor setups in office or home environments. Those who appreciate biometric convenience will find the fingerprint scanner and front camera useful for daily login and video conferencing.

Who is this NOT for?

Users looking for a laptop suited to demanding graphics workloads or gaming will find this machine limiting, as the integrated Intel Iris Xe GPU lacks ray tracing and DLSS support and is not designed for rendering or GPU-intensive applications. The absence of Thunderbolt ports, USB 4, and a modern HDMI version makes it a poor fit for professionals who depend on high-bandwidth peripherals or high-resolution external displays. Those who frequently work in locations without reliable Wi-Fi and need a wired network connection will also face friction, as there is no built-in RJ45 ethernet port. Users with strict on-the-go charging habits may find the lack of sleep-and-charge ports inconvenient as well.
