Asus Zenbook A14 test: 978 grams, record autonomy and performance capable of shaking Intel and AMD… but a major flaw for me (and it’s not its Snapdragon x2 chip)

Less than a kilo on the scale, an ARM chip that outperforms Intel and AMD processors in raw performance, and autonomy such that you forget your charger: the Zenbook A14 version 2026 promises to shake up the segment of premium ultraportables under Windows. With its Snapdragon X2 Elite, Asus offers the most credible response to date to Apple’s MacBook Air M5. We used it on a daily basis for several weeks and the observation is clear: this machine excels where Windows ultrabooks have always failed, namely weight and endurance. But at 1949€ in the configuration tested (32 GB / 1 TB), there is no room for error. And it is clear that concessions persist, starting with ventilation that is too noisy as soon as the processor is called upon, an OLED screen whose brightness remains average and connectivity that is a little sparse for this price level. Is the Zenbook A14 the best Windows ultraportable of the year? Not sure. Or at least, not for everyone.

A Ceraluminum chassis under the kilo mark: the “wow” effect

The first handling of the Zenbook A14 causes a real surprise effect. With its 978 grams, you have the impression of holding an empty chassis, a sensation that we have never experienced to this extent on a 14 inch. To give an idea, it’s 260 grams less than a MacBook Air 13 M5 (1.24 Kg) and almost 220 grams less than the Zenbook S 14 UX5406S that we tested at the end of 2024. With a little less than 16 mm thick, the format is certainly not the thinnest in the segment but it remains very compact and fits easily into any cover.

This record lightness is made possible by Ceraluminum, a composite material developed by Asus which combines aluminum and ceramic. We discovered it on the Zenbook S 16 then on the first generation of the Zenbook A14: the surface is matte, slightly rough to the touch, with a mineral finish which is not unanimous on the aesthetic level but which presents an undeniable practical advantage. Fingerprints end up being visible but much less than on a classic aluminum chassis or, worse, than on the black surface of the ProArt P16 which attracts fingerprints like a magnet. The “Iceland Gray” color of our example features a sober, professional light gray that blends into any environment.

In terms of rigidity, nothing to complain about. The base unit absorbs pressure without flinching. The hood shows a little more flexibility but nothing worrying for this weight category. The hinges, however, could have benefited from a little more firmness: the screen oscillates slightly when typing on the move.

The connection is one of the first complaints made against this Zenbook A14. Two USB-C 4.0 ports (40 Gbps, DisplayPort, Power Delivery), one HDMI 2.1, one USB-A 3.2 Gen 2 and one 3.5 mm jack. On paper, it’s okay for an ultraportable. In practice, the two USB-Cs are positioned on the left and one of them is monopolized by the charge. There is therefore only one really usable USB-C port left, which quickly requires the purchase of a hub. The absence of an SD (or microSD) card reader and the inability to charge the device from the right side are regrettable, especially on a machine priced at almost €2000.

Another surprise, the charger is no longer supplied in the box. The decision does not come from Asus but from a new European standard, the same as that which applies to smartphones. The idea is justified on an ecological level but is even more questionable on a laptop. Especially since we noticed that our 100W all-battery USB-C chargers trigger a “slow charger” message. Enough to push the user towards a unit of 140W or more for peaceful use.

On the wireless side, WiFi 7 (Qualcomm FastConnect 7800) and Bluetooth 5.4 are included. A good point for the future, especially for people equipped with a compatible router.

A convincing keyboard and a functional touchpad

At the opening, sobriety reigns. The keyboard retains the good habits of recent Zenbooks with generously sized keys (16.3×15.4 mm), well spaced (3 mm) and equipped with a travel of 1.4 mm. If the surface of the keys has the same grainy texture as the chassis, which will not appeal to everyone, the typing itself is remarkable. The damping is precise, the feedback frank and the typing noise almost imperceptible. For long writing sessions, this is one of the best keyboards we’ve come across on an ARM ultraportable. The white backlight offers three intensity levels, sufficient for nighttime use.

The glass touchpad (12.5×8 cm) offers smooth gliding and good precision. Its dimensions remain modest compared to those of certain competitors but prove sufficient for everyday use. The gestures on the edges (volume, brightness) work but are more of a gadget than an essential, as we had already pointed out on previous Asus models equipped with this functionality.

The 1080p webcam allows you to enjoy Windows Hello using facial recognition. In terms of image quality, unsurprisingly, the rendering remains average with a marked noise as soon as the brightness declines. Classic.

A half-tone OLED screen: correct but too tight for the price

The Zenbook A14 has a 14-inch OLED panel in 16:10 format, with a definition of 1920×1200 pixels and a refresh rate of 60 Hz. As expected with this technology, the blacks are absolute and the contrast rate virtually infinite. Color coverage is excellent with almost all sRGB and DCI-P3 spaces covered, a DeltaE measured at 1.2 and a native white point measured at 6550K. Asus also offers pre-calibrated colorimetric profiles (sRGB, Display P3) that can be used directly for photo editing.

On the other hand, the maximum brightness caps at around 400 nits in SDR. This is sufficient for working indoors in good conditions, but the shiny surface of the slab generates marked reflections as soon as ambient lighting comes into play. On a terrace or in a bright coworking space, comfort is felt. For comparison, the ProArt P16 2025 and its Tandem OLED reach 690 nits in SDR. Certainly, the comparison is not entirely fair given the different positioning, but on a product priced at €1949, we would have appreciated more brightness, in the absence of an effective anti-reflective treatment.

The other limitation is the refresh rate, fixed at 60 Hz. When you are used to the 120 Hz panels present on most recent premium ultrabooks (including the MacBook Air M5 with its ProMotion at 120 Hz), the return to 60 Hz is noticeable, especially when scrolling web pages. OLED partially compensates thanks to its almost instantaneous response time (0.2 ms) but this is a point which begins to become difficult to defend in 2026.

No touch option on this configuration, which is not a shortage for the majority of office uses.

Snapdragon X2 Elite: Impressive CPU performance, provided the software keeps up

The heart of this Zenbook A14 is based on the Snapdragon 4.7 GHz is a generational leap compared to the Snapdragon X which equipped the 2025 version of the same Zenbook A14. The RAM reaches 32 GB of LPDDR5x on our configuration, soldered to the chip and therefore not upgradeable. Nothing surprising but an element not to be overlooked when purchasing. The 1 TB Micron SSD displays sequential read speeds of around 7000 MB/s.

Under Geekbench 6, the Snapdragon X2 Elite displays 3774 points in single-core and 20380 in multi-core. To put these figures into perspective, that’s 29% more in single-core and 31% more in multi-core than the AMD Ryzen AI 9 HX 370 which equips the ProArt P16 and Zephyrus G14 2025. All in a chassis weighing less than a kilo, without a dedicated GPU. The progression compared to the Snapdragon X of the previous generation is just as spectacular, with a gain of around 50% in single-core.

Under Handbrake, the results are truly astonishing. With 13 seconds to encode a 4K source in H.265, the Zenbook A14 is ahead of machines with GeForce RTX 5070 and RTX 5090. The explanation lies in the combination of software natively compiled for ARM and a processor whose raw power now outperforms the x86 competition in this thermal envelope.

In practice, however, this performance varies significantly depending on the software. Under DaVinci Resolve 19, whose ARM optimization can still be improved, exporting a 2-minute YouTube project in 1080p requires approximately 54 seconds in Performance mode. This is correct for an ultraportable without a dedicated GPU but clearly behind machines equipped with NVIDIA graphics cards, such as the ProArt P16 2025 (16 seconds with the RTX 5090) or the Zephyrus G14 2025 (22 seconds with the RTX 5070 under DaVinci 17). The GPU acceleration of the integrated Adreno X2-90 cannot compete with a dedicated GPU on this type of workload.

This observation perfectly illustrates the duality of the ARM platform in 2026. When the software is natively optimized (Handbrake, the Office suite, browsers, certain Adobe tools), the Snapdragon X2 Elite proves formidable. As soon as x86 emulation comes into play or GPU acceleration is requested, performance drops. Qualcomm has made considerable progress in compatibility since the initial launch of the Snapdragon Be careful if you use “exotic” software.

The integrated Hexagon NPU displays 80 TOPS, meeting the requirements of Microsoft’s Copilot+ PCs. Under Geekbench AI, the CPU Quantized score reached 7442 points. In practice, the daily usefulness of these AI capabilities remains limited to Windows Studio features (webcam effects, live subtitling) and a few Adobe tools. The trend is accelerating but we are not there yet.

Fans too present for an ultraportable of this caliber

The Zenbook A14’s cooling system relies on two fans and a heat pipe. The Ceraluminum chassis dissipates heat well at rest, with surface temperatures barely warm to the touch. Under load, the processor stabilizes around 72°C under DaVinci, completely reasonable values. The contact areas (wrist rest, touchpad) remain cool in all circumstances.

The problem lies with noise pollution. In Standard mode, we noted around 43 dBA, an audible level in a quiet environment. As soon as the Performance profile is activated or the processor is heavily loaded, the noise rises to around 54 dBA. For an ultraportable weighing less than a kilo sold as a nomadic companion, that’s too much. The frequency of the fans, which is quite high, is also not the most pleasant and the speed variations amplify the feeling of discomfort.

Silent mode allows you to achieve almost total silence (less than 30 dBA) but at the cost of a significant reduction in performance, the processor then being limited to around 15W. For office use and web browsing, this mode is more than sufficient and the impression of performance remains excellent. On the other hand, for any creative work requiring sustained power, you will have to deal with the blowing of the fans.

On the audio side, the two stereo speakers deliver decent sound for such a compact chassis. The output logically lacks bass and warmth but the power is sufficient for a video conference or streaming video. Nothing surprising at this level of size.

Autonomy that changes the game: THE real argument of this Zenbook

Autonomy is undoubtedly the most spectacular asset of this Zenbook A14. The 70 Wh battery, combined with the remarkable energy efficiency of the ARM Snapdragon X2 architecture, produces results we have never seen on a Windows laptop. In web browsing (WiFi active, brightness set to 160 nits), we only lost 11% of battery in 4 hours of use. In real use, over a long day of work mixing office work, web browsing, messaging and light editing, the Zenbook A14 still had 50% battery at the end of the day.

Enough to calmly consider two days of work between two tasks for mainly office use. This is simply unprecedented under Windows and comparable, if not superior, to what Apple’s MacBook Air M5 offers. Remember that the Zenbook S 14 UX5406S under Intel Lunar Lake reached 12 hours in the same exercise. The first generation Snapdragon ultrabooks we tested showed between 15 and 20 hours. The Snapdragon X2 Elite takes it a step further.

Another good point: performance remains stable on battery, where x86 ultrabooks often show a significant drop. A decisive advantage for nomads.

Our opinion on the Asus Zenbook A14 (UX3407N)

With this 2026 Zenbook A14, Asus asks a fundamental question: are you ready to accept the constraints of the ARM ecosystem under Windows to benefit from record weight and unprecedented autonomy? If weight and endurance are your priority criteria, the answer is yes without hesitation. No Windows competitor manages to offer such a balance between lightness (978 grams), CPU power and autonomy. The Snapdragon X2 Elite outperforms Intel and AMD competition in raw processor performance and rivals the Apple M5 in power efficiency. The Ceraluminum chassis is robust, the keyboard pleasant and the colorimetry of the OLED screen impeccable.

On the downside, noise pollution constitutes the main complaint. An ultraportable that aims to be the silent companion of nomads should not blow at 54 dBA as soon as the processor is requested. The brightness of the screen (400 nits, glossy surface) remains correct but insufficient given the price, especially compared to a MacBook Air M5 which now displays 120 Hz and a more generous brightness. The connectivity, with a single USB-C port that can really be used and the absence of a charger in the box, leaves a taste of unfinished business on a product costing €1949.

There remains the question of software compatibility. Windows on ARM has progressed considerably but is not without friction for users of specific professional software. If your daily life consists of web browsing, the Office suite, photo editing in Lightroom and videoconferencing, the Zenbook A14 is a formidable companion.

Ultimately, the Zenbook A14 Snapdragon At least in this high-end configuration that was loaned to us. The more affordable versions, around €1000, will certainly be a little less efficient but nevertheless sufficient for most users. And above all more homogeneous in terms of price/service ratio. The MacBook Air M5 remains a formidable rival, notably thanks to a more mature software ecosystem and a more aggressive quality/price ratio on entry-level configurations. But for Windows-loving users who put mobility at the top of their priorities, the Zenbook A14 is arguably the best choice available today.
