If you’ve ever wanted a no-nonsense Windows laptop that feels as sleek and sharp as a MacBook Air but with a dash of futureproof AI acceleration, the Asus Vivobook S14 (M3407KA) might be exactly what you’re looking for.

I’ve been using this machine, powered by the AMD Ryzen AI 7 350, for everything from work to light gaming, and I can say with confidence: this is a seriously competent ultraportable that doesn’t just chase trends. It builds a practical, intelligent foundation for the next generation of computing.

Design and Build Quality

The Vivobook S14 might not be the flashiest device in the room, but it blends in well. The Matte Gray finish on my unit looks subdued and classy, with a CNC-engraved chrome Asus Vivobook logo that adds a bit of character without drawing too much attention. The overall design feels clean and minimal, and it does not attract fingerprints the way some glossier ZenBooks tend to.

It weighs just 1.4 kg and measures about 15.9 mm in thickness, which makes it easy to carry around in a backpack. Despite the lightweight design, the build feels solid. There is no flex in the keyboard deck, no noticeable screen wobble, and the hinge supports a full 180-degree lay-flat design. Asus also meets MIL STD 810H military-grade durability standards, which adds confidence when using the laptop in cafes or during travel assignments.

Display

The 14-inch OLED panel with thin bezels on this laptop looks excellent. Asus labels it as a Lumina OLED display, a panel technology used across several of its professional laptops. The 1920×1200 resolution, combined with a 16:10 aspect ratio, works well for productivity. Text appears sharp, colors look vibrant without appearing exaggerated, and black levels are deep, as expected from an OLED panel.

Asus claims support for 1.07 billion colors and full 100% DCI P3 color gamut coverage, making the display suitable for casual creative work such as photo editing and light color grading. Since this model is not aimed at gaming, it features a standard 60Hz refresh rate.

For eye comfort, the display supports low blue light hardware certification and DC Dimming. This avoids PWM flicker at lower brightness levels and helps reduce eye strain during extended work sessions or nighttime use.

Brightness peaks at around 300-400 nits, which is suitable for indoor use and remains usable outdoors as long as direct sunlight is avoided. The display uses a glossy finish, so reflections are visible at times, but Asus includes an anti-reflective coating to reduce glare.

To be honest, the Vivobook S14’s display is class-leading for its segment. Many competitors at similar prices offer only IPS LCDs (often lower resolution or lower color gamut), whereas Asus has made OLED more accessible. The only trade-offs to be aware of are the typical ones with OLED: potential image retention if static content is left for hours. However, Asus mitigates this with pixel shifting and a screensaver timeout.

But this is a minor issue in day-to-day use. Having such a high-quality panel on a laptop geared at students and working professionals means you get an ultra-portable device that’s excellent for watching movies, doing creative hobby work, or simply enjoying a beautiful Windows UI every day. It’s a big selling point for the Vivobook S14.

Ports and Connectivity

Asus equips the Vivobook S14 with a well-balanced selection of ports. It includes two USB-C 3.2 Gen 1 ports that support both charging and DisplayPort output, along with two USB-A ports for older peripherals, a full-size HDMI 2.1 port, and a 3.5 mm audio jack.

The laptop omits an SD or microSD card slot, which could disappoint creators and photographers, but overall, it covers the essentials without the need for extra adapters.

Wireless performance is equally solid. With Wi-Fi 6E and Bluetooth 5.3, I didn’t face any hiccups during my use, whether it was pairing devices or maintaining a stable connection across tasks.

Keyboard and Trackpad

Typing on this laptop feels comfortable and precise. The keyboard provides 1.7 mm of travel, which is impressive for a thin and light device. Each key offers a quiet yet tactile response, and the deck feels solid enough to support extended writing sessions without flex. I have typed entire articles, including this one, without needing an external keyboard. It also includes a backlight for easier use in dim environments.

The trackpad is spacious, smooth, and highly responsive. Its large surface area takes a little getting used to, and I initially experienced a few accidental palm touches, though it quickly became manageable. Palm rejection could use minor improvement, but it does not interfere with regular use. Clicks feel slightly firm near the edges, while tap-to-click functions accurately. Multi-finger gestures such as three-finger swipes, four-finger taps, and pinch to zoom are well supported and work seamlessly.

Benchmarks

Here’s how the Vivobook S14 (Ryzen AI 7 350, Radeon 860M) performed in my benchmarking suite:

• PCMark 10: 7,490 overall – Fast and fluid in day-to-day use.
• Cinebench R23: 1,957 (single) / 16,233 (multi) – Stellar single-core, strong multi-core.
• Geekbench 6: 2,856 (single) / 11,027 (multi) – Reinforces its everyday snappiness.
• 3DMark Time Spy: 1,961 overall – OK for integrated graphics.
• 3DMark Steel Nomad Light: 1,452 – Shows limitations for modern AAA gaming.
• Geekbench AI (quantized): 7,935 – Impressive for on-device AI tasks.
• CrystalDiskMark: 6,752 MB/s read / 3,683 MB/s write – Fast Gen 4 SSD, no slowdowns.

These numbers put it in solid upper-midrange territory, above budget machines and well into premium thin-and-light territory without costing flagship money.

AI and Performance

This is where the Vivobook starts to separate itself. The Ryzen AI 7 350 features an XDNA NPU capable of 50 TOPS, and that matters, especially as Windows 11 leans into AI integration. Copilot, background blur in video calls, real-time translation, and local AI summarization all run smoother and more efficiently on this chip than on older CPU or GPU-bound systems.

And it is not just theoretical. I used AI-powered features in Office apps, Windows Studio Effects, and several local applications that benefit from NPU offload, and they consistently performed without any issues. The advantage lies in the quiet and efficient operation, as AI tasks happen seamlessly in the background without draining the battery or triggering fan noise.

In terms of raw performance, the laptop never felt limited during everyday workloads. It handled heavy Chrome sessions, 1080p video editing, large WordPress dashboards, and even moderate gaming with ease.

Gaming

No, this isn’t a gaming laptop. But the Radeon 860M GPU with RDNA 3.5 architecture is surprisingly capable for an integrated chip. I tested a few titles:

• Valorant: 170-230 fps (Low settings, 1080p)
• Genshin Impact: 60 fps (Low), 20-25 fps (High)
• PUBG: ~50 fps (Lowest settings)

These aren’t groundbreaking numbers, but for an ultrabook? Very respectable. If you’re into casual gaming, this can hold its own.

Thermal and Fan Performance

Asus has done an excellent job with thermal management on this laptop. Even during benchmarks or light gaming, the fans never became noticeably loud. Most of the time, they stayed silent, especially when running in Standard or Whisper mode. When pushed in Performance mode, fan noise hovered around 38 dB, producing a low whoosh rather than a distracting sound.

Temperatures remained in the 75s °C range under load, with very little heat buildup across the chassis. After a Valorant session, the keyboard area felt only slightly warm, and the palm rest stayed cool. This efficiency comes from the dual fan cooling system that Asus adapted from its higher wattage designs, which provides more cooling headroom than the chip actually requires.

Battery Life, Sound, and Camera

Asus claims up to 23 hours of battery life, and while I did not reach that exact figure, I consistently achieved around 10 to 12 hours in real-world use. For my workflow of writing, browsing, streaming music, and light photo editing, I only needed to charge it every other day. When recharging was necessary, the 65W USB-C fast charging brought the battery back to 50% in under 40 minutes.

Audio performance is solid for a thin and light laptop. The stereo speakers deliver clear sound at high volume levels without noticeable distortion. Bass is limited, as expected, but the output remains crisp enough for calls, videos, and casual music playback. Asus’s Audio Booster tuning adds a bit of warmth and depth. For critical listening, headphones are still preferable, but the built-in speakers perform well for everyday use.

The 1080p webcam also performs well. It supports Windows Hello facial recognition through an IR sensor, enabling quick and reliable logins. Video quality is good enough under good lighting conditions, and the built-in microphone array captures voices clearly for online meetings. It may not rival dedicated webcams in sharpness, but with AI background blur and enhancements, it handles video calls effectively and without any issues.

Storage and Upgradability

The Vivobook S14 delivers impressive storage performance with its PCIe Gen 4 SSD. The review unit I tested featured a 512GB NVMe PCIe 4.0 drive, while Asus also offers a 1TB option depending on the configuration. Sequential read speeds exceeded 6,700 MB/s, and write speeds reached around 3,600 MB/s in testing. These results translate into fast app launches, smooth multitasking, and quick file access.

For memory, the laptop comes with 16GB of DDR5 RAM onboard, which is fast and efficient for daily productivity and creative workloads. Unlike many ultrabooks, Asus includes a DDR5 SO-DIMM slot for future upgrades, allowing users to expand memory beyond 16 GB if required.

The storage is also user accessible via a standard M.2 2280 PCIe 4.0×4 slot, making it possible to replace or expand the SSD later. This mix of soldered and upgradable components gives the Vivobook S14 more flexibility than most thin and light laptops in its class.

Verdict

After spending more than two weeks with the Asus Vivobook S14 (M3407), it is clear that this is one of the most balanced ultrabooks in its category. It does not aim to be a creator’s workstation or a gaming powerhouse, but it delivers strongly on the essentials: productivity, portability, battery life, and AI readiness.

The combination of Ryzen AI 7 350 processor and its integrated NPU makes it future-ready for AI-assisted tasks, while the OLED display and comfortable keyboard make daily use enjoyable and efficient.

It starts at Rs. 78,990 for this variant in India, and for students, bloggers, professionals, and anyone who values responsiveness, battery endurance, and a great screen over high-end graphics performance, this laptop is a strong fit.
