Asus VivoBook 16 (M1607) 16" VS Asus VivoBook S 14 (M3407) 14"

Both the VivoBook 16 and the VivoBook S 14 are classed as Productivity machines, and they share several design traits: neither uses a fanless architecture, both feature a backlit keyboard, and neither offers weather-sealing or a rugged build. These shared omissions set realistic expectations — these are everyday office and study laptops, not built for harsh environments.

Where the two diverge meaningfully is in portability. The VivoBook S 14 weighs 1390 g versus the VivoBook 16's 1880 g — a difference of nearly 490 g, which is roughly the weight of a large smartphone. Over the course of a day of commuting or campus use, that gap is genuinely noticeable on the shoulder. The smaller footprint of the S 14 (315 × 223 mm vs. 357 × 250 mm) also means it slips into bags more easily and takes up less desk space. Its overall volume is about 17% smaller than the VivoBook 16's. The one counterpoint is thickness: the S 14 is fractionally thicker at 18 mm versus 17 mm for the VivoBook 16, but this 1 mm difference is imperceptible in practice.

On design, the VivoBook S 14 has a clear portability edge. It is significantly lighter and more compact without any meaningful trade-off in build style. The VivoBook 16's larger chassis is an inherent consequence of its bigger screen, not a design advantage — users who prioritize mobility should favor the S 14, while those who don't mind the extra bulk for a larger display will find the VivoBook 16 otherwise comparable in design philosophy.

Despite the size gap between them, both laptops share the same 1920 x 1200 px resolution and 60Hz refresh rate. The 1200-pixel vertical resolution (a 16:10 aspect ratio) is a practical advantage over standard 1080p panels for both machines — the extra vertical space is genuinely useful for documents, spreadsheets, and web browsing, reducing the need to scroll.

Fitting the same resolution into a smaller screen directly benefits the VivoBook S 14: its 161 ppi pixel density is noticeably sharper than the VivoBook 16's 141 ppi. In practical terms, text and fine details appear crisper on the S 14's panel, which matters for long reading or coding sessions. The flip side is that the VivoBook 16's larger 16″ canvas gives more breathing room for side-by-side windows and media consumption — it's a bigger workspace, just not a sharper one. Neither display supports touch input, and both can drive up to 4 external displays, making them equally capable as multi-monitor workstation hubs.

The most decisive differentiator here is the VivoBook 16's anti-reflection coating, which the S 14 lacks entirely. In bright or mixed-lighting environments — offices with overhead lights, cafés, or near windows — a glossy panel without anti-glare treatment can become a real hindrance. This partially offsets the S 14's sharpness advantage for users who frequently work in variable lighting. Overall, the display comparison is genuinely split: the VivoBook S 14 wins on pixel density, while the VivoBook 16 wins on glare resistance — your environment and use case should drive the decision.

At the foundation, these two machines are remarkably similar: both pack 32GB of DDR5 RAM, a 1TB NVMe PCIe 4.0 SSD, and 16 CPU threads built on a 4nm process. For everyday productivity workloads — multitasking, office applications, browser-heavy sessions — either machine is well-equipped, and the fast storage ensures snappy boot and load times on both.

The CPU configuration is where a real gap opens up. The VivoBook 16's processor runs at a base clock of 2 GHz across its cores, while the VivoBook S 14's chip runs at a substantially higher 4 GHz base. In sustained workloads — think video exports, large dataset processing, or extended compilation tasks — a higher base clock means the S 14 maintains stronger performance without relying on boost. Its turbo ceiling of 5.2 GHz also edges out the VivoBook 16's 5 GHz, reinforcing its lead in peak single-core scenarios. The GPU picture is more nuanced: the S 14's integrated GPU opens at 800 MHz versus the VivoBook 16's 400 MHz, giving the S 14 a decisive advantage in sustained graphics tasks, though the VivoBook 16 pulls ahead slightly at peak with a turbo of 3000 MHz compared to the S 14's 2800 MHz — a minor edge that matters only in brief burst scenarios.

Taken together, the VivoBook S 14 holds a clear performance advantage in this group. Its higher CPU base and turbo clocks make a tangible difference under sustained load, and its GPU base clock lead further widens the gap for graphics-adjacent tasks. The VivoBook 16 counters only marginally with a slightly higher GPU turbo, which is unlikely to translate into a meaningful real-world difference for the productivity users both laptops target.

The Asus VivoBook 16 (M1607) and the Asus VivoBook S 14 (M3407) show some differences in benchmark results. The VivoBook 16 has a PassMark result of 34459, while the VivoBook S 14 has a lower result of 31104. This indicates that the VivoBook 16 generally performs better in overall multi-core tasks.

For single-core performance, the VivoBook S 14 slightly outperforms the VivoBook 16 with a PassMark result of 3970 compared to 3878. While the difference is not very large, it indicates that the VivoBook S 14 may have a small advantage in tasks that rely more heavily on single-core processing.

In summary, the VivoBook 16 excels in overall multi-core performance, while the VivoBook S 14 has a marginally better single-core benchmark result.

The connectivity features of the Asus VivoBook 16 (M1607) and the Asus VivoBook S 14 (M3407) are quite similar, with both offering a range of USB ports and wireless capabilities.
