The Nightsky series is Eurocom's latest family of narrow bezels laptops for enthusiast gamers. It currently consists of the 15.6-inch Nightsky RX15 and 17.3-inch Nightsky RX17 which we had checked out earlier last month. Both models share a similar design language and so we recommend checking out our Nightsky RX17 review page to learn more about the chassis, keyboard, and other physical features.
The Nightsky Ti15/RX15 can be configured with either a Core i7-9750H or unlocked Core i9-9980HK CPU, GeForce GTX 1660 Ti or GeForce RTX 2070 GPU, and a 144/240 Hz 1080p IPS or 60 Hz 4K UHD OLED display. Our test unit today is the lower Ti15 configuration with GeForce 1660 Ti graphics, i7-9750H CPU, and 144 Hz panel retailing for about 2200 USD or less depending on the storage selection. The Nightsky Ti 15 is otherwise visually identical to the Nightsky RX15.
Direct competitors to the Eurocom Nightsky TI15/RX15 include other 15.6-inch mid-range to higher-end gaming laptops like the Asus Zephyrus M GM501, Asus ROG Strix Scar G531, MSI GE63, Razer Blade 15, Aorus 15, or the Dell Alienware m15 series.
More Eurocom reviews:
Case
Chassis quality is so much better than the super-thin Eurocom Q6 or Q8. Surfaces do not creak or bend as easily and they actually feel thicker and more robust. In other words, it doesn't feel like Clevo made as many sacrifices just to create a thinner or lighter design. The lid in particular does not feel any weaker or stronger than the lids of the larger Eurocom Sky X4C or Tornado F5 for a strong first impression. Overall quality is superior to the MSI GP65 and on par with the Asus ROG Strix III G531.

In terms of size and weight, the Eurocom is very nearly the same as the HP Pavilion Gaming 15 but much thicker (29.9 mm vs. 23.4 mm) and slightly heavier (2.5 kg vs. 2.4 kg). The narrow bezels make this one of the smallest and most compact 15-inch gaming laptops from Clevo thus far.
Connectivity
Port options and positioning are the same as on the larger 17.3-inch Nightsky RX17 including the unusual SD card reader along the front edge. The system has more ports than most other gaming laptops.
SD Card Reader
Eurocom laptops typically have very fast SD card readers and the Nightsky series is no exception. Moving 1 GB worth of pictures from our UHS-II test card to desktop takes only about 6 seconds compared to almost 15 seconds on the HP Omen 15.
A fully inserted SD card sites almost flush against the edge of the chassis for safe transporting.

Maintenance
Much like on the Nightsky RX17, the Ti15/RX15 is one of the more difficult Clevo systems to service. You'll potentially have to remove the keyboard just to pop open the bottom panel and upgrade something as simple as RAM or storage.
Warranty
The standard one-year limited warranty applies with options to extend up to three years.
Input Devices
Keyboard and Touchpad
The Nightsky RX15 shares the same keyboard and touchpad as on the RX17 despite their screen size differences. Even the dimensions of the touchpad between the two models are identical. Thus, all our comments from the Nightsky RX17 apply here on the RX15.
Display
The AU Optronics B156HAN 144 Hz IPS panel here can also be found on other gaming laptops like the Dell G5 15 5590, Alienware m15, or Asus Zephyrus S GX531GX for a similar viewing experience between them. Contrast ratio is high at nearly 1000:1, response times are fast at about 4 ms to 7 ms for reduced ghosting, and brightness is brighter than on both the HP Omen 15 and the aforementioned Dell. The panel is slightly grainy but that is to be expected from a matte overlay.
Perhaps the worst aspect of the display is its moderate uneven backlight bleeding as shown by our picture below. A small level of bleeding is always expected from most IPS panels, but it's disappointing to see it here on at such noticeable levels especially on an enthusiast gaming laptop.

Color space is not unlike most Ultrabooks at >90 percent sRGB and about 60 percent of AdobeRGB. It may not be HDR compatible, but it's good enough for gaming purposes.
Further measurements with an X-Rite colorimeter reveal generally good grayscale and colors out of the box. Our calibration attempt improves the display even further with final average grayscale and color deltaE values of 2.2 and 3.27, respectively.

Outdoor visibility is pretty good when under shade, but otherwise poor when under sunlight or on a bright cloudy day. This system was not designed to be used outdoors frequently despite the matte panel, narrow bezels, and wide viewing angles.
Performance
The Eurocom Nightsky 15 series is unusual because it has only Core i7 and Core i9 options with GeForce GTX 1660 Ti or RTX 2070 graphics and nothing else. This makes the system one of the only gaming laptops you can configure with an enthusiast Core i9-9980HK CPU and a budget-midrange GTX 1660 Ti.
LatencyMon shows no DPC latency issues. Eurocom and Clevo systems are generally very light when it comes to pre-loaded applications and so background activities are kept to a minimum.
Processor
CPU performance is almost 10 percent faster than the average Core i7-9750H in our database according to CineBench R15. However, this healthy lead doesn't last very long as maximum Turbo Boost is only temporary. When running CineBench R15 Multi-Thread in a loop, performance drops by about 15 percent from the high initial score as shown by our graph below. Raw performance is still significantly faster than the quad-core Core i7-9300H and older Core i7-7700HQ by about 60 to 70 percent.
See our dedicated page on the Core i7-9750H for more technical information and benchmark comparisons.

Storage Devices
There are two M.2 PCIe slots with RAID compatibility and a single 2.5-inch SATA III bay available. Our unit comes equipped with a single 512 GB Samsung SSD 970 Pro with sequential read and write rates of over 2100 MB/s each according to AS SSD. Samsung produces some of the fastest NVMe drives for consumers and this is no different.
Since servicing can be a pain, however, we recommend configuring wisely before committing to a purchase.

Emissions
System Noise
The cooling solution consists of twin fans and five copper heat pipes between them. The fans are pretty good at staying quiet for as long as possible before needing to really ramp up. When set to Quiet mode, fan noise maxes out at 34.8 dB(A) but it's oftentimes much lower and almost inaudible if simply web browsing or streaming.
When gaming, however, fan noise will be as loud as most other mid-size gaming laptops like the Aorus 15 or MSI GE63 at almost 54 dB(A). Some alternatives, like the Razer Blade 15, are noticeably quieter at about 45 dB(A) when under the same gaming conditions. We find headphones to be a necessity when fan noise reaches 50 dB(A) and above.
We can notice no coil whine or electronic noise on our test unit.

Temperature
Surface temperatures are warmest towards the center of the keyboard where it can around 38 C to 42 C when gaming. Fortunately, the palm rests, NumPad, and WASD keys remain cool no matter the load for comfortable gaming. Hot spots are actually a bit warmer than expected during low loads since the fans are running much quieter and more slowly.
(±) The maximum temperature on the upper side is 42.6 °C / 109 F, compared to the average of 40.2 °C / 104 F, ranging from 21.6 to 68.8 °C for the class Gaming.
(-) The bottom heats up to a maximum of 69 °C / 156 F, compared to the average of 43 °C / 109 F
(±) In idle usage, the average temperature for the upper side is 35.5 °C / 96 F, compared to the device average of 33.7 °C / 93 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 33.1 °C / 92 F, compared to the device average of 33.7 °C / 93 F.
(±) The palmrests and touchpad can get very hot to the touch with a maximum of 36 °C / 96.8 F.
(-) The average temperature of the palmrest area of similar devices was 29 °C / 84.2 F (-7 °C / -12.6 F).
Stress Test
We stress the system with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU will spike to 4 GHz for the about 20 seconds until it hits 80 C. Thereafter, clock rates drop to the 3.2 to 3.3 GHz range in order to maintain a cooler core temperature of 66 C. This behavior backs up both our CineBench loop test results above and power consumption observations below. When at 100 percent CPU and GPU utilization, CPU and GPU temperatures stabilize at 88 C and 80 C, respectively.
Running Witcher 3 is more representative of real-world loads. Here, CPU and GPU temperatures each stabilize at 75 C and 73 C. We can observe no performance throttling no matter the load.
Running on batteries will impact overall performance. A Fire Strike run on batteries returns Physics and Graphics scores of 11264 and 1177 points, respectively, compared to 16961 and 15343 points when on mains.
| CPU Clock (GHz) | GPU Clock (MHz) | Average CPU Temperature (°C) | Average GPU Temperature (°C) | |

Speakers
The 2 W stereo speakers of the Nightsky RX15 are lacking the dedicated 4 W subwoofer of its bigger 17.3-inch Nightsky RX17 counterpart. Bass is thus noticeably poorer, but the chassis appears to vibrate much less because of it. Maximum volume is otherwise nearly identical to the Nightsky RX17.

Power Consumption
Idling on desktop demands anywhere between 16 W and 31 W which is higher than most other 15.6-inch gaming laptops like the older MSI GE63. This may be responsible for the unimpressive battery life in our next section. When gaming, consumption averages 141 W not unlike the Aorus 15-SA with the same CPU and GPU.
At most, we're able to record 192.3 W from the small-medium (~14.3 x 7.3 x 2.3 cm) 180 W AC adapter.

Battery Life
Expect a real-world WLAN runtime of only 3.5 hours when set to the Balanced power profile to be average for a gaming laptop. The Dell G5 15 5590 with the faster RTX 2060 GPU can last for over two times longer despite having a similar battery capacity.
Recharging from empty to full capacity takes about 2 hours.
