Asus VivoBook S 14 (M3407) 14" specifications and in-depth review

Asus VivoBook S 14 (M3407) 14"

Manufacturer: Asus

The Asus VivoBook S 14 (M3407) is a 14-inch productivity laptop built around a slim 18mm chassis that weighs just 1,390g, making it a practical choice for everyday computing tasks. It pairs a 1920x1200 pixel display with 3D facial recognition for secure login, a backlit keyboard, stereo speakers, and a front-facing camera, rounding out a feature set oriented toward daily work and communication.

Under the hood, the VivoBook S 14 runs on an 8-core processor with a turbo clock speed reaching 5.2GHz, backed by 32GB of DDR5 memory clocked at up to 7,500MHz across dual channels. Storage is handled by a 1TB NVMe PCIe 4.0 SSD, while graphics are managed by the integrated AMD Radeon 780M with 768 shading units and a GPU turbo of 2,800MHz. Connectivity includes two USB 3.2 Gen 1 Type-C ports, two USB 3.2 Gen 1 Type-A ports, HDMI 2.1 output, Wi-Fi 6, and Bluetooth 5.3, with the 70Wh battery supporting sleep-and-charge functionality.

Pros
  • 32GB of DDR5 RAM running at up to 7,500MHz across dual channels gives the system strong memory bandwidth for multitasking and demanding productivity workloads
  • The 1TB NVMe PCIe 4.0 SSD ensures fast file access and quick application load times
  • A 70Wh battery is a generously sized cell for a 14-inch laptop, supporting extended use between charges
  • 3D facial recognition provides a convenient and secure way to log in without requiring a fingerprint scanner
  • The system supports up to 4 external displays simultaneously, making it well-suited for multi-monitor work environments
  • At 18mm thick and 1,390g, the chassis is slim and light enough for regular daily transport
Cons
  • The display is limited to a 60Hz refresh rate with no touch input and lacks an anti-reflection coating, which can be a drawback in bright environments
  • USB connectivity tops out at USB 3.2 Gen 1 speeds with no higher-bandwidth options such as USB 4 or Thunderbolt, and there is no RJ45 port for wired networking
  • Only a single memory slot is available, meaning RAM cannot be expanded beyond the 32GB already installed
  • The integrated Radeon 780M does not support ray tracing or DLSS, limiting its suitability for graphically intensive tasks
  • A single microphone and no Dolby Atmos support make the audio setup fairly basic for calls and media consumption
  • The laptop is not weather-sealed or ruggedized, offering no protection against moisture or physical stress
Who is this for?

This laptop is a strong fit for office and productivity-focused users who need reliable multitasking capability, thanks to its 32GB of DDR5 RAM, fast NVMe PCIe 4.0 storage, and an 8-core processor that turbos up to 5.2GHz. The support for up to 4 external displays makes it particularly well-suited for professionals who rely on multi-monitor setups, such as developers, analysts, or content editors working across multiple windows. Its slim 18mm build, 1,390g weight, and 70Wh battery also make it a practical choice for users who work on the move and need a portable machine that can last through a full day without frequent charging stops.

Who is this NOT for?

Users looking for a machine capable of graphically intensive work or gaming will find this laptop limiting, as the integrated Radeon 780M does not support ray tracing or DLSS and lacks the dedicated GPU headroom needed for rendering, 3D modeling, or modern gaming at higher settings. The 60Hz display with no touch support and no anti-reflection coating makes it a poor match for creative professionals who prioritize color-accurate, smooth, or touch-enabled screens. Additionally, users who require fast external data transfers or wired networking will be constrained by the absence of USB 4, Thunderbolt ports, and an RJ45 connector, making it unsuitable for workflows dependent on high-speed peripheral or network connectivity.
