MagyarRunning an AMD Ryzen 9 5900X on a laptop: Eurocom Nightsky ARX15 review
Not to be confused with the Nightsky RX15, the Nightsky ARX15 utilizes desktop AMD CPUs and a different chassis than its Intel counterpart. Its paper specifications alone should make the ARX15 one of the fastest 15.6-inch laptops you can buy in terms of raw CPU performance. The configuration we have in review retails for around $3400 USD with much lower or higher prices available depending on storage.
Additional information on the Nightsky ARX15 can be found on its official page here. The chassis is based off of the Clevo NH57AF1 and so users will find many similarities between the Eurocom Nightsky ARX15 and the Schenker XMG Apex 15.

Case
The chassis remains larger and heavier relative to other 15.6-inch gaming laptops with more traditional mobile H-series CPUs like the MSI GE66 or Asus ROG Strix G15. Our chassis impressions on the Schenker Apex 15 apply here for the Nightsky ARX15.
Connectivity
There are fewer port options here when compared to the RX15. There is only one USB-C port instead of two, for example, and it doesn't support Thunderbolt or Power Delivery. In contrast, most MSI, Asus, and Alienware laptops have the option to recharge via USB-C.
SD Card Reader
Transfer rates from the integrated MicroSD reader are decent but still disappointing relative to the price of the system. Moving 1 GB of pictures from our UHS-II test card to desktop takes about 15 seconds compared to less than half that on the MSI GE66 Raider 10SFS.

Communication
Webcam
The system comes equipped with a 720p webcam whereas the Eurocom Sky X4C comes with a higher resolution 1080p webcam. There is no privacy shutter or IR camera. Instead, there is an Fn key to disable the camera electronically.
Maintenance
The bottom panel pops off easily after removing the five Philips screws. Users have direct access to all common components including the two DDR4 SODIMM slots and three storage bays.
Accessories and Warranty
The retail box includes a manual, drivers disk, Windows 10 USB drive, additional screws, SSD thermal pad, and two 0.6g thermal paste syringes. The standard one-year limited warranty applies with the option to extend up to 3 years.
Input Devices
Display
The Nightsky ARX15 uses a very similar Sharp LQ156M1JW03 IPS panel as the ones found on the MSI GE66 or Delta 15. Thus, the viewing experience is almost identical between these three models with their 240 Hz native refresh rates, ~1000:1 contrast ratios, full sRGB coverage, fast response times, and even similar pulse-width modulation frequencies. It's a high-end panel with excellent attributes even if its colors and contrast can't quite reach the same levels as OLED panels.

Color temperature is cooler than expected which impacts color accuracy and overall Delta E values. Eurocom will personally calibrate the display for an additional charge. We recommend calibrating the display in order to better exploit the full sRGB coverage of the panel.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 23150 Hz | ≤ 34 % brightness setting |  |
The display backlight flickers at 23150 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 34 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 23150 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Performance
Testing Conditions
Our unit was set to both High Performance mode via Windows and Performance mode with Maximum fan mode active via Control Center 3.0 for the highest possible scores on stock OEM settings. We recommend users become familiar with the Control Center software as many auxiliary features can be toggled here.
Processor
Multi-thread performance is disappointing when compared to our desktop Ryzen 9 5900X reference. Our Eurocom Ryzen 9 5900X is consistently slower by about 30 to 40 percent to be more in line with the mobile Ryzen 9 5900HX.

System Performance
PCMark 10 scores are excellent and comparable to the MSI Delta 15. However, we do not recommend setting Control Center to Power Saving mode or Quiet mode as system performance will slow to a crawl. Simple browsing or OS navigation will become very laggy with constant mouse cursor jumps and frame skips. Users should instead remain on Entertainment mode or Performance mode for a smoother experience.
Furthermore, the system takes an unusually long time to wake from sleep. Typical laptops or Ultrabooks would take less than a couple of seconds whereas our Eurocom would always take upwards of 10 seconds.

Storage Devices
Eurocom offers a wide selection of NVMe SSDs ranging from just 250 GB up to 8 TB. Our unit has been configured with the Samsung SSD 980 Pro which is a PCIe4 x4 NVMe SSD capable of transfer rates of up to 7000 MB/s. Unfortunately, the M.2 slots on the Nightsky ARX15 are PCIe3 x4 only and so transfer rates will be much slower at up to around 3200 MB/s. You may want to save yourself some cash and only configure with less expensive PCIe3 drives since the motherboard cannot fully exploit the performance benefits of pricier PCIe4 drives.

Emissions
System Noise
Fan noise is dependent on the four Control Center power profile settings: Power Saving, Quiet, Entertainment, or Performance. The system runs very quietly (~27.9 dB(A)) on the first two settings, but overall performance would suffer so dramatically that the system can feel like molasses. Meanwhile, fan noise will often spike to as high as 40.8 dB(A) even if running undemanding loads on Performance mode. We recommend running on Entertainment mode as it offers the better balance between system performance and the constantly pulsing fans.
Gaming will induce a fan noise between 52 and 56 dB(A) to be not unlike most other high-performance 15.6-inch gaming laptops. Fan noise can reach over 60 dB(A) when Maximum Fan mode is active.

Temperature
Surface temperatures are warm even when idling on Power Saving mode or Quiet mode since fan noise is being pushed to much quieter limits. Hot spots can be as warm as 27 C and 43 C on the top and bottom, respectively. The keyboard keys are therefore always warm but thankfully never uncomfortably when running high loads as the loud fans do a good job at keeping surface temperatures in check.
(+) The maximum temperature on the upper side is 36.2 °C / 97 F, compared to the average of 40.4 °C / 105 F, ranging from 21.2 to 68.8 °C for the class Gaming.
(-) The bottom heats up to a maximum of 49.6 °C / 121 F, compared to the average of 43.2 °C / 110 F
(+) In idle usage, the average temperature for the upper side is 27 °C / 81 F, compared to the device average of 33.8 °C / 93 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 30 °C / 86 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.9 °C / 84 F (-1.1 °C / -2 F).

Stress Test
When running Prime95 with Maximum Fan mode off, the CPU would stabilize at around 1.9 GHz and at a core temperature of 67 C. Enabling Maximum Fan mode would cause clock rates to stabilize at 3.8 GHz and with a lower core temperature of 54 C. In comparison, our Ryzen 9 5900X desktop reference would instead stabilize at a much higher 4.5 GHz clock rate when subjected to the same Prime95 conditions which would explain the slower-than-expected CPU benchmark results of our Eurocom mentioned above. Fortunately, there is enough of a temperature headroom for end-user overclocking if desired albeit at the cost of very loud fan noise. CPU package power would stabilize in the 82 W to 88 W range when on stock settings.
Running Witcher 3 on Maximum Fan mode would result in a stable GPU clock rate and temperature of 1605 MHz and 70 C, respectively, compared to 1365 MHz and 74 C on the Asus TUF Dash F15 equipped with the same GeForce RTX 3070 GPU.
Running on battery power will limit performance. A 3DMark 11 test on batteries would return Physics and Graphics scores of 3398 and 7357 points, respectively, compared to 19082 and 36118 points when on mains.

Energy Management
Power Consumption
Power consumption is very high no matter the activity which may explain the poor battery life in the next section. Simply idling on desktop would consume between 55 W and 73 W compared to 12 W and 35 W on the older Intel-powered Nightsky RX15. The wide delta doesn't shrink when running higher loads like games. The Gigabyte A5 X1, which uses the same RTX 3070 GPU but the mobile Ryzen 9 5900HX CPU instead, would demand around 25 to 30 W less than our Eurocom when under heavier loads.
We're able to record a maximum draw of 256 W from the large (~18 x 8.5 x 3.5 cm) 280 W AC adapter when running Prime95 and FurMark simultaneously.

Battery Life
Runtimes on the balanced profile (or Quiet) setting are so poor that it takes much longer to charge the battery from empty to full than it takes to discharge the battery when simply web browsing (120 minutes vs 61 minutes). The battery is easy removable unlike on most other laptops, but capacity is rather small at 62 Wh when compared to other large 15.6-inch laptops like the MSI GE66.

Pros
Cons
Verdict
There are a couple of issues that need to be addressed: the very slow wake times and the horrendously laggy performance when set to Power Saving mode or Quiet mode. These two features are significantly slower here on the Nightsky ARX15 when compared to a standard Ultrabook that's a fraction of the cost.
It's not recommended to run this system on stock settings for those who wish to exploit the Ryzen 9 5900X to its maximum potential. CPU performance will underperform when compared to a proper desktop with the same Ryzen 9 5900X meaning users must overclock our mobile Ryzen 9 5900X to bring it up to par. Our tests show that there is indeed some headroom available, but the resulting fan noise will be very loud and potentially bothersome. Nonetheless, Eurocom continues to be one of the very few companies to offer laptops with desktop CPUs as many larger makers like MSI and Alienware have been focusing less on such "super performance" laptops.
