Rating: 4.2 out of 5 stars

As you read further on this ASUS VivoBook E403SA-US21 review you will realize that this is laptop built to function in wide variety of environments.

This laptop has a few tricks up sleeves that truly put it on a completely different standard as compared to the rest in the same price range.

We hope you learn something from this ASUS VivoBook E403SA-US21 review.

For starters, like all Vivobooks this laptop features a very elegant classy and slim design, which is always a charm and welcome in laptops if it comes at an affordable price of course.

In fact, Vivobooks have been designed to compete with ultrabooks that are much more expensive than Vivobooks. Although they are still not as great as some of the premium ultrabook like the ASUS Zenbooks, the fact that this laptop is available at three times the less amount should make you think twice.

How is the Processor Performance?

At the heart of this laptop is the latest Intel Braswell Quad Core N3700. Now this is processor does not hail from the famous Core i3, i5 or i7 lines of processors. In terms of performance, it is definitely lacking when comparing it with Core series processors.

However, that does not mean that it cannot perform. This processor is not only budget friendly but also has a very low TDP giving you the battery life that can last for hours on this laptop.

Braswell processors are SoC (system on a chip) CPUs, which means the processing cores, memory controller, video engine, and even the chipset are integrated in a single die. It helps to keep the cost and the thermal dissipation low. –

This proves that this may not be the most powerful processor around, it is however one of the most power efficient.

ASUS VivoBook E403SA-US21 has some other great stuff underneath its beautiful shell. To complement the processor this laptop features 4 GB of RAM capacity that is more than adequate for a fast multitasking experience.

In all reality, you won’t be needing more than this amount of RAM on a laptop that has a low performance processor. This is actually a good thing. There are laptops available that combine 6 GB or higher RAMs with Intel Pentium processor. But that is not a great combination as the processor will most certainly bottle neck the RAM.

What is this eMMC Drive?

Furthermore, ASUS VivoBook E403SA-US21 offers 128 GB eMMC Flash Drive. Now this is not as fast as an SSD drive, but it is much faster than a tradition HDD drive. Furthermore, the eMMC Flash Drive enables more power conservation as well as enables the laptop be as thin as it is. With tradition mechanical HDD this is not possible. Of course we are taking the price range in consideration when comparing.


Now, the features that makes Vivobook standout from the rest is that it combines all the aforementioned aspects within a great portable design. Weighing at less than 3.3 pounds and with a profile that is only 0.7 inch thick at most, this notebook is one of the most portable entertainment budget laptop.

It is hard to imagine that just a few years back having a laptop that is less than an inch thick at twice the price range was considered huge. This laptop really is the testament of how far we have come as far as laptop design is concerned.

With its slim profile this laptop does sacrifice on optical drive, but who really uses it these days. People usually settle for cheap external optical drive if they ever need it.

Is it Future Proof?

ASUS VivoBook E403SA-US21 Review 5The story of this laptop does not just end there. This laptop is future prove and built for next generation interfacing devices. This laptop not only has USB 3.0, it also has USB 3.1 type C, which is set to replace the standard USB port in the near future. The laptop also has Wifi and Bluetooth 4.0 along with an HDMI port.

Fanless Experience

The fact that this laptop does not have any fans inside means that you can have a comfortable experience with it. The processor and the overall design of this laptop enables it to dispense the heat passively. This is actually great. How many times have you seen a laptop become damaged or start making noise because its fan has given up.

If you work in the laptops line of industry you will receive many complaints of laptop overheating because their fan has given up etc. With this laptop, you will have no such issues.

How is the Battery?

Since this laptop has power efficient components and no mechanical component like an optical drive or an hard disk drive, the battery life is humongous. ASUS VivoBook E403SA-US21 can last for 14 hrs!

Who is This Laptop For?

This is a budget laptop. With that in mind this laptop is most certainly not designed for professional work or for gamers. It is designed solely for those who need a digital companion for surfing the web, word processing or just staying connected.

Since it is slim, sleek and slender, it is an ideal choice for those who always on the go, outdoor living and also for students. They will appreciate the light weight and the battery life ASUS VivoBook E403SA-US21 has to offer.


This is greatest aspect of this laptop. Hands down. Hats Off to ASUS for making such an amazing next gen laptop that is thin and light at a price tag of just nearly four hundred bucks (at the time of writing this review).

Very rarely do you find laptop that are as great as this and as cheap.
