There seems to be a lot of components in ASUS Zenbook UX303UB that make power users happy. First, there’s a Core i7 processor that belongs to the latest 6th Generation. Second, and equally important, is a whopping 512GB solid-state drive – thousand times better than a mere hard drive. Furthermore, the 13.3″ screen sports not Full HD but more, a quad HD resolution. So really, is there anything wrong with this computer? Perhaps, I’ll elaborate that below!

What are its advantages?

I don’t think you would ever run out of processing power with ASUS Zenbook UX303UB. Processor here is Intel Core i7-6500U, with two cores, 2.5GHz clock speed and 3.1GHz turbo boost. It’s a 6th Gen model, based on Skylake microarchitecture, and it’s indeed tad faster than its predecessors – CPU Mark gives ~4300 points for this while the i7-5500U would get around 4000. These are excellent numbers considering we’re looking at a mobile, not desktop, processors. You shouldn’t need to worry about any software lagging with this kind of benchmark score.

Other advantages include 12GB memory, 4GB of that seems to soldered on board and 8GB is installed on a regular DIMM stick. The current 12GB is most this system takes, and not even power users would need more than that – quite honestly most people would be fine with 4-8GB memory.

Storage is golden here, it’s a 512GB real SSD (no hybrid drive). It gives pretty much storage space but the best thing is obviously the added performance benefit, which can be seen in Windows loading times for example.

The 13.3″ display with 3200×1800 resolution (Quad HD) surely looks professional, but if you’re really using that resolution you must be a hawk – so small will icons, text and everything look on this screen. But don’t worry, you can always change the resolution, 1920×1080 should work nicely. The panel type is naturally IPS and it’s a glossy screen. Touch is supported as well.

Could it be a bad choice for somebody?

It’s a well-rounded laptop for demanding use, there aren’t big drawbacks in the features I can think of, but of course somebody looking for a machine for web surfing wouldn’t need this fancy computer. It’s an expensive item, and only if you can put all the powerful components to good use it would make sense to get this notebook.

One thing you should know is the limited gaming performance. True, there’s a graphics card called GeForce 940M that uses dedicated 2GB DDR3 memory. On the other hand, it’s not a very powerful engine. You can surely play most, if not all, games, but the question is what settings you should use. With demanding types like GTA 5 you’ll have luck using medium settings and 1366×768, that’ll give you ~50 frames per second. I’ve also seen The Witcher 3 played on this card, it will run at ~30FPS using 720p and low settings.

Connections and ports

ASUS Zenbook UX303UB has just three USB ports, but a good thing, they’re all USB 3.0. There’s also the obligatory HDMI and in addition, a miniDP port, so you can plug in many kinds of external monitors. Optical drive is not there because of small unit size, luckily you can use external drive for discs. Memory cards can be slipped in, there’s SD card slot for them.

WiFi interface is good, type is 802.11AC with Bluetooth 4.0 support. RJ-45 jack isn’t available, but you can get USB dongle for that.

Webcam supports HD resolution, you should be able to film decent quality videos with that.

What other things I need to know?

ASUS Zenbook UX303UB includes a 3-cell 50Whr battery, you’ll get around 6 hours if you’re surfing the web.

The keys light up, backlit keyboard is a norm in this expensive notebooks.

The unit weighs 3.2 pounds and the system is loaded with Windows 10.


ASUS Zenbook UX303UB is all about premium. The fast processor, a lot of RAM and extremely fast SSD make sure that power users, professionals and techies are all good to run their exotic and power-hungry applications. Gamers are also not forgotten, although the GT940M card isn’t too powerful – you’d need to make sacrifices on resolution and setting in games. The price is pretty high but considering what you’ll be getting, the value here is decent at least.
