Asus Zenbook S UX393JA Laptop Review: The Microsoft Surface Alternative
Last year's ZenBook S13 UX392 combined a Whiskey Lake-U CPU with a GeForce MX150 GPU in an attractive 16:9 form factor. This year's ZenBook S UX393 could have been a simple update, but Asus has gone the extra mile by completely redesigning the chassis and internals for a brand new look yet again. The UX393 makes the jump from 16:9 to 3:2 and foregoes the discrete Nvidia GPU for Intel Ice Lake and Iris Plus instead. Though aesthetically pleasing, there are a few key drawbacks to keep in mind before putting down $1600 to $1700 USD for such a machine.
Direct competitors to the ZenBook S13 UX393 include other flagship 3:2 like the Microsoft Surface Laptop 3 or Huawei MateBook X Pro. The 16:10 Dell XPS 13 or ThinkPad X1 Nano may also be seen as alternatives to the Asus.

Case
The metal chassis is firm and rigid with no creaking and only minimal warping when attempting to twist its corners. Our main complaint involves the hinges which feel weaker at wider angles. Ideally, hinge rigidity should be taut and uniform at all angles, but the hinges here don't give a strong sense of longevity in this regard.
The move from 16:9 to 3:2 has resulted in a larger, heavier, and thicker build than the UX392. Overall dimensions and weight are actually much closer to the 13.5-inch Surface Laptop 3 or MateBook X Pro and so this is still a compact subnotebook relative to its closest competitors.
Connectivity
Port options are similar to the older UX392 but with two important differences. Firstly, Asus has dropped the 3.5 mm audio jack meaning owners will have to rely on Bluetooth headphones or the included USB-C to 3.5 mm audio adapter. Secondly, the two USB-C ports are now Thunderbolt 3 compatible for a wider range of external docking options and monitors.
SD Card Reader
Transfer rates from the MicroSD reader are slower than the card reader on the older UX392 by half. Moving 1 GB of pictures from our UHS-II test card to desktop takes almost 30 seconds.

Communication
The AX201 comes standard for Wi-Fi 6 connectivity. Though we didn't experience any issues when connected to our Netgear RAX200 test router, average transmit speeds are slower than expected at only about 822 Mbps.
Webcam
Maintenance
The bottom panel comes off easily with just a T5 Torx wrench. However, there's not much to upgrade beyond the M.2 SSD as both WLAN and RAM are soldered.
Accessories and Warranty
The retail box includes a USB-C to 3.5 mm audio adapter and a protective carrying sleeve in addition to the usual paperwork and AC adapter. The standard one-year limited warranty applies.
Input Devices
Keyboard
Keyboard layout remains identical to the UX392 save for some secondary function changes on the first row of keys. Travel is shallow while the Space and Enter keys clatter more loudly than the main QWERTY keys when pressed. Feedback is otherwise decent if not slightly softer than on the HP Spectre 13 series.
Touchpad
The sizeable clickpad (13 x 6.5 cm) is only slightly smaller than the one on the Surface Laptop 3 (11.5 x 7.6 cm) while being much larger than the clickpad on the older UX392 (10.5 x 6.2 cm). Its surface is completely smooth with only minimal sticking when gliding at slower speeds. Its integrated mouse clicks, however, are far too shallow and with weak feedback.
Display
The 3:2 AU Optronics B139KAN01.0 can be found on no other laptop in our database. When compared to the Sharp and JDI panels on the Surface Laptop 3 13.5 and MateBook X Pro, respectively, native resolution is higher and color space is slightly wider as it covers all of DCI-P3. Asus calibrates each panel at factory in accordance to the standard.
Although the touchscreen is gorgeous at first glance, there are some downsides. Brightness and contrast are not on the same level as the MateBook X Pro display and response times are still slow for noticeable ghosting. This latter characteristic is common on many Ultrabooks since most users will not be gaming on these machines.

Color space covers all of sRGB and 78 percent of AdobeRGB. Note that Asus advertises full DCI-P3 coverage meaning a small portion of the color space will not overlap with the AdobeRGB standard. Indeed, this is what we can observe as approximately 16 percent of the color space lies outside of AdobeRGB.
X-Rite colorimeter measurements reveal a well-calibrated display out of the box. Color temperature is slightly too cool which can be easily addressed.

Performance
Processor
CPU performance is within just a few percentage points of the average Core i7-1065G7 in our database taken from about 30 other laptops. When compared to the Core i7-8565U in last year's UX392, multi-thread performance is only about 15 percent faster after accounting for any performance throttling on both systems. Turbo Boost performance is not as long lasting as other laptops including the older UX392 as illustrated by our CineBench R15 xT loop comparison graph below.

Storage Devices
Asus laptops commonly come with Intel 660p SSDs and our UX393 is no exception. Unlike higher-end NVMe SSDs that can approach 3000 MB/s, however, transfer rates on this mid-range 1 TB Intel 660p cap out at "only" 1800 MB/s. This will not significantly impact real-world scenarios especially on an Ultrabook powered by a U-series CPU.

GPU Performance
Graphics performance is where we expect it to be relative to other laptops with the same Iris Plus G7 GPU if not slightly higher. 3DMark results also show it to be neck-to-neck with the GeForce MX150 in the older UX392. Nonetheless, real-world gaming performance will often be slower than the MX150 due to various factors in favor of the Nvidia GPU including more optimized drivers, dedicated VRAM, and a higher TDP ceiling of up to 25 W.

Emissions
System Noise
The laptop fan is usually active but barely audible when in a typical office environment. Web browsing or video streaming, for example, will result in a slight fan noise of 31 dB(A) but it will otherwise not induce any annoying fan pulsing behavior. Running higher loads like games will nonetheless cause the Asus to run at about 40 dB(A) or as loudly as the Surface Laptop or MateBook X Pro.
We recommend owners become familiar with the MyAsus software as fan profiles and other systems settings can be found here.

Temperature
Surface temperatures will always be warmer on the left half of the laptop than the right half due to the how the cooling solution and CPU are positioned inside. When under high processing stress like gaming, hot spots can become as warm as 43 C or 48 C on the keyboard or bottom surfaces, respectively, to be similar to the XPS 13 9300. Expect warm keys after longer sessions of browsing or heavy use.
(±) The maximum temperature on the upper side is 42 °C / 108 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(-) The bottom heats up to a maximum of 48.6 °C / 119 F, compared to the average of 39.4 °C / 103 F

Stress Test
When under Prime95 stress, the CPU would stabilize at 1.9 GHz and at a core temperature of 73 C to be both warmer and slower than what we observed on the Whiskey Lake-U-powered UX392. CPU clock rates would boost up to 3.5 GHz for only the first second or so before falling to be in line with what we observed during our CineBench xT loop test and power consumption readings.
When running Witcher 3, the CPU would again stabilize at a warmer temperature of 76 C compared to only 60 C to 68 C on the older UX392. Running on battery power will limit performance; a 3DMark 11 run on batteries would return Physics and Graphics and scores of 7076 and 3541 points, respectively, compared to 9119 and 4222 points when on mains.

Power Consumption
Overall power consumption is similar to the 15-inch Microsoft Surface Laptop 3 albeit by just a few watts less on average. It's also not all that different from the older GeForce MX150-powered UX392FN either despite the swap to an Ice Lake CPU and GPU.
We're able to measure a maximum draw of 61.6 W from the small (6.4 x 6.4 x 2.8 cm) AC adapter when running Prime95 and FurMark. This rate would quickly fall over time since Turbo Boost clock rates are not sustainable over long periods.

Battery Life
Battery capacity is larger than on the last generation UX392 (67 Wh vs. 50 Wh), but WLAN runtimes remain about the same. We're able to record just over 8 hours of real-world browsing use which is average for an Ultrabook or subnotebook.
Recharging from empty to full capacity takes just over 2 hours.

Pros
Cons
Verdict
There is both a lot to like about the ZenBook S UX393 and also a lot that can be improved. When compared to the Surface Laptop 3 13, the Asus blows it out of the water as it is able to offer a larger, brighter, more colorful and higher resolution display within the same chassis size. It also sports more ports than the Microsoft laptop which doesn't even have Thunderbolt 3, HDMI, or an easily accessible M.2 SSD. The Surface Laptop 3 feels barebones and outdated once you become accustomed to the Asus.
The advantages aren't as clear-cut when compared to the Huawei MateBook X Pro. The Huawei system is indubitably faster in terms of GPU power since it uses discrete Nvidia MX graphics and its keyboard keys are firmer and more comfortable to type on. The lack of both a webcam shutter and 3.5 mm audio port on the Asus is puzzling while the slow MicroSD reader may annoy content creators. The UX393 is still a notable upgrade over the UX392 in spite of the size increase, warmer temperatures, and bumpy Ice Lake performance.
The high-end Asus ZenBook S UX393 feels great to hold and travel with and its 3:2 touchscreen is impressive. However, we would love to see GeForce MX and Ryzen options instead of relying solely on Ice Lake CPUs.
