MagyarAsus VivoBook 15 K570UD (i7-8550U, GTX 1050) Laptop Review
Unlike the premium Zenbook series or gaming-centric ROG series, the affordable Vivobook series appeals to multimedia users on tighter budgets not unlike the Dell Inspiron, HP Pavilion, Lenovo Ideapad, or Acer Aspire. The latest Vivobook is the X570UD that combines an 8th gen Intel U-class CPU with a GeForce GTX 1050 GPU for about $1000 USD.
Current SKUs include the i5-8250U or i7-8550U with FHD or 4K UHD panels, HDD and SSD storage options, and 4 GB to 32 GB of DDR4 RAM. Direct competitors are numerous in the 15.6-inch category such as the MSI GL63, HP Envy 15, Dell G5, Lenovo Ideapad 720, Gigabyte Sabre 15, and Asus' own TUF FX504 series.
Depending on the region, this model may be listed as the Vivobook X570UD or Vivobook K570UD.
Case
The chassis design is a derivative of the higher-end Zephyrus series. The rear ventilation grilles and sharp corners along the lid are reminiscent to the pricier ROG GX501 or GU501 series. For our Vivobook, however, expect plastic from top to bottom for a budget impression more in line with what one would expect from a Pavilion 15 or Ideapad 530 series. Both the base and hinges are sufficiently rigid while the lid is more susceptible to warping from its corners and down the center. The "Lightning Blue" accent marks along the perimeter is a nice visual touch to help distinguish the Vivobook from the more powerful red and orange ROG alternatives.
Build quality is excellent with no creaking or unintended gaps between materials. The rough faux brushed aluminum surfaces help in hiding fingerprints and scratches.
The Vivobook is relatively small and light for a 15-inch notebook with GTX 1050 graphics. Competing systems like the Legion Y520 and Gigabyte Sabre 15G are thicker and a few hundred grams heavier without necessarily being any faster.
Connectivity
Ports are easy to reach and evenly distributed along the left and right edges. It's interesting to see a MicroSD reader instead of a full-size SD reader given the screen size, though it's certainly better than having no card reader at all. Note that native 4k60 output is not possible because of the lack of both HDMI 2.0 and mini-DisplayPort features.
SD Card Reader
Average transfer rates from the MicroSD reader are about 80 MB/s when using our Toshiba UHS-II test card. It's important to note that the card reader is not spring-loaded and a fully inserted card will still protrude by about 2 mm. Bending is a possibility if the card is not removed before transporting.

Maintenance
The bottom panel is secured by a set of 11 Philips screws. Unfortunately, The X570UD is designed in such a way that some motherboard components are also attached to the bottom panel with multiple ribbon cables connecting the panel to the rest of the laptop. Serviceability is not easy because the fragile cables must be detached and then reattached with additional tools.
The poor serviceability is a shame since there are 2x expandabile SODIMM slots and 2x storage bays available.
Warranty
The standard one-year limited manufacturer warranty applies when purchased in North America. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.
Input Devices
Keyboard and Touchpad
The keyboard could have been better in terms of feedback. Keys are light, shallow in travel, and have a cheap plastic impression. The Space and Enter keys in particular are spongy and could have been firmer.
The integrated NumPad is very small and far too cramped for comfortable use. We would have preferred omitting it altogether in return for a better overall typing experience on the main QWERTY keys.
The smooth plastic trackpad (10.5 x 7.5 cm) feels very similar to the ones found on the FX503 or FX504. Glide is uniform when moving at moderate speeds while the finger tends to stick when moving more slowly. Unlike the rest of the notebook, the matte surface is more susceptible to grease buildup over time. Performing mouse clicks on the integrated keys is on the spongy side as well.
Display
The 1080p matte display is crisp without any major graininess issues. Its AU Optronics B156HAN06.1 IPS panel can also be found on the Asus FX503VM and a number of budget Acer laptops like the Spin 5 SP515. Consequently, our Vivobook shares many of the same display characteristics as the aforementioned laptops. Contrast is good albeit with average brightness levels and black-white response times.
Our unit exhibits minor uneven backlight bleeding on the bottom corners that is fortunately unnoticeable during day-to-day loads.

Color space is only 58 percent and 37 percent of the sRGB and AdobeRGB standards, respectively, which is representative of a budget panel. Users who want deeper and more accurate colors may want to consider the ZenBook series instead where 100 percent sRGB options are common.
Further measurements with an X-Rite spectrophotometer reveal generally accurate colors and grayscale. Nonetheless, color accuracy is limited by the narrow gamut and we can observe that colors become increasingly inaccurate at higher saturation levels. Our calibration attempts improve the display just marginally.

Outdoor visibility is below average because of the mediocre display backlight. The wide IPS viewing angles and matte display do little to alleviate the dim screen and washed out colors.
Performance
The X570UD is rather unique because of its combination of a U-class i7-8550U CPU and a GeForce GTX 1050 GPU. While both processors are common, they are not often found together because most notebooks prefer to pair GTX graphics with Intel HQ-class processors instead. Optimus is included by default for switching to the UHD Graphics 620 when desired.
No other GPU options are available for now other than the GeForce GTX 1050.
Processor
CPU performance is good but not perfect. When running CineBench R15 Multi-Thread in a loop, the initial high score of 708 points is unsustainable because subsequent runs return lower scores in the 550 range as shown in our graph below. While the 22 percent performance drop is disappointing, users can still expect a rough 50 percent increase over the last generation i7-7500U.

Storage Devices
Internal storage options include M.2 2280 and a 2.5-inch SATA III bay. The PCIe x2 SK Hynix PC300 primary M.2 SSD in our test unit returns much faster transfer rates when compared to SATA III solutions as expected, but the drive still pales in comparison to PCIe x4 Samsung solutions like the PM961. Our secondary 1 TB Seagate HDD shows an average transfer rate of 80 MB/s which is typical of a 5400 RPM drive.

GPU Performance
The GTX 1050 in the VivoBook is performing exactly where we expect it to be when compared to the average GTX 1050 in our database to indicate no throttling behavior. Users can expect a 50 to 60 percent raw performance increase from the GTX 960M or up to 70 to 80 percent from the GeForce MX150 commonly found on newer Ultrabooks. Demanding titles are playable in 1080p with graphical settings tuned down.

Stress Test
We stress the notebook with synthetic benchmarks to identify for any potential throttling issues. When subjected to Prime95 stress, the CPU can be observed running at 3.2 GHz for the first few seconds before reaching 82 C. Once this temperature threshold is reached, the clock rate will throttle down to 2.3 GHz in order to maintain a cooler core temperature. This behavior mirrors our CineBench loop test results from above. When under Prime95 and FurMark stress, core temperatures will settle in the mid 80 C range.
Running Witcher 3 is more representative of real-world gaming loads. CPU and GPU temperatures stabilize in the 70 C range each with steady performance throughout.
Running on battery power will limit both CPU and GPU performance. A 3DMark 11 run on batteries returns Physics and Graphics scores of 6689 and 5097 points, respectively, compared to 8112 and 7563 points when on mains.

Emissions
System Noise
The cooling solution consists of one fan and two heat pipes for both the CPU and GPU. When idling, fan noise is essentially unnoticeable in even quiet environments. Unfortunately, the fan can be sensitive to onscreen loads and so we recommend the Power Saver profile if streaming or browsing.
Higher loads like gaming can be as loud as 44 dB(A) to be louder than the MSI GL63 but comparable to the old Pavilion 15 Power. Despite not being advertised as a gaming notebook, the X570UD can certainly sound like one.
We can notice no electronic noise or coil whine on our test unit.

Temperature
When idling, the keyboard and palm rests are cool while the bottom rear of the notebook can be noticeably warmer by several degrees. The right palm rest in particular will always be warmer than the left because the 2.5-inch drive is installed directly underneath.
When under heavy load, the center keyboard and bottom surfaces can be as warm as 40 C and 50 C, respectively. Fortunately, the WASD keys remain relatively cool and the bottom hot spot is towards the rear of the unit as illustrated by our temperature maps below. The warm surfaces never become uncomfortable when typing or gaming on a flat desk.
(+) The maximum temperature on the upper side is 39.8 °C / 104 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(-) The bottom heats up to a maximum of 53.4 °C / 128 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 24.7 °C / 76 F, compared to the device average of 31.3 °C / 88 F.
(+) Playing The Witcher 3, the average temperature for the upper side is 30.5 °C / 87 F, compared to the device average of 31.3 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28 °C / 82.4 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (+0.8 °C / 1.4 F).
Speakers
The stereo 2 W speakers offer decent sound quality when considering the price. Bass is average, but the palm rests reverberate more noticeably when on higher volume settings compared to other laptops. Expect to bump up the volume for videos and movies since the maximum output is on the modest side.

Energy Management
Power Consumption
Power consumption is slightly below the Sabre 15G and GL63 when under load since these competing systems utilize more demanding 45 W HQ-class CPUs. Maximum load demands 103 W from a medium-sized (~15.8 x 7.5 x 2.8 cm) 120 W AC adapter.

Battery Life
Expect just under 5.5 hours of real-world WLAN use when set to the Balanced profile. Runtimes are generally longer than a traditional gaming laptop while being a few hours shorter than the latest Ultrabooks with slower integrated graphics.

Verdict
The Asus X570UD proves that you don't need an Intel HQ-class CPU to play the latest games. The 15 W Kaby Lake-R series offers a performance level in between that of the 45 W Core i5-7300HQ and i7-7700HQ commonly found on inexpensive gaming laptops. The lower cooling requirements mean a lighter and more portable system without sacrificing gaming performance or uncomfortably high core temperatures. The i7-8550U and GTX 1050 pairing is something we'd love to see on more thin-and-light gaming laptops not unlike the older Blade 14 and its i7-7500U and GTX 960M.
Of course, there are some cut corners to be aware of since the Vivobook is a budget-mainstream offering. The weak keyboard and trackpad leave a cheap impression and the poor serviceability is a hindrance to users who want to upgrade storage or RAM. Other than these drawbacks, the X570UD/K570UD is a good balance for on-the-go students who want something affordable, lightweight, and also capable of playing the latest games.
Lighter than the Dell G5, Lenovo Legion Y520, and Gigabyte Sabre 15 while being just as powerful and inexpensive. The Asus Vivobook K570UD/X570UD skips the luxuries for an adequate core experience and respectable gaming prowess.
