The ASUS Vivobook S14 (S3407) with Snapdragon X is a light 14-inch Copilot+ laptop with long battery life, a 45-TOPS NPU, and modern ports. Pick the OLED WUXGA for rich color or the 2.5K IPS for sharper text. It’s ideal for students and remote workers who live in Office, Chrome, and video calls. Creators who need Adobe plug-ins or niche x86 apps should double-check compatibility first.

What’s new with the Snapdragon X Vivobook S14
This is ASUS’s 14-inch Copilot+ take aimed at long battery life and fast on-device AI. The integrated NPU (up to 45 TOPS) accelerates Windows Studio Effects, Recall-class features (as they roll out), and background tasks like live captions or image cleanup. You don’t need a cloud round-trip for those, which helps both speed and privacy.
Performance expectations. In everyday work multiple Edge tabs, Docs, Slack, video calls Snapdragon X models have felt quick in early reviews of sibling Vivobook 14 units, with a big advantage in unplugged runtime versus similarly priced Intel machines. Displays vary by config, so panel choice matters more than you’d think.
Battery life. ASUS quotes up to ~30.5 hours on this family depending on workload. In practice, students and remote workers can expect “a full day plus,” especially if you keep brightness around 150–200 nits and stick to browser/Office work. Video editing or emulated x86 apps will cut that down.
Display choices: WUXGA OLED vs 2.5K IPS
WUXGA OLED (1920×1200) inky blacks, wide color (~95% DCI-P3). Great for movies and photo viewing. Text looks fine at 14-inch, but it’s not razor-sharp.
2.5K IPS (2560×1600) sharper text for coding and spreadsheets; 100% sRGB and ~400 nits. Colors are accurate, just not as punchy as OLED.
If you write, code, or read a lot, the 2.5K IPS is the safer pick. If you watch films or want richer visuals, the OLED feels special.
Ports, wireless, and upgradability
You get two USB-A, two USB4 Type-C with DisplayPort + Power Delivery, HDMI 2.1 (TMDS), and a 3.5 mm jack solid for a thin 14-inch. Wi-Fi 6E is standard. Upgrades are simple for storage, but note ASUS’s fine print: only single-sided M.2 SSDs are supported, so choose a compatible drive if you swap later. RAM is on-board (choose the capacity you need at purchase).
Who should (and shouldn’t) buy it
Buy it if you:
- Want a light 14-inch with long battery life, good keyboard, and modern USB4 connectivity.
- Live in Microsoft 365, Google Workspace, and web apps; value quieter fans and cool temps.
- Want on-device AI assists without hammering the battery.
Think twice if you:
- Depend on niche x86 plugins/drivers that may lag on ARM Windows.
- Need a high-refresh (120 Hz+) panel or dedicated GPU for gaming.
- Do heavy Adobe/DaVinci work today and can’t wait for ARM-native updates.
Alternatives to consider
- ASUS Vivobook 14 (X1407QA) still Snapdragon X, usually cheaper, but watch the LCD quality on budget configs. Good for students on a strict budget.
- Vivobook S14 (Intel Core Ultra Series 2) if your workflow uses legacy Windows apps or specific x86 drivers, this path avoids emulation. Battery won’t be as strong.
- Vivobook S14 (AMD Ryzen AI 9 HX 370) solid mixed CPU/GPU loads. Pricing and availability vary by region.
