Eurocom Nightsky RX15 (Clevo PB51RF, Core i9, 4K OLED) Laptop Review

Unlocked Core i9 with OLED. The Nightsky RX15 is one of the few narrow-bezel 15.6-inch laptops offering unlocked Core i9-9980HK CPU options. Meanwhile, its OLED option makes the system competitive against the Razer Blade 15, Alienware m15, and Gigabyte Aero 15 which all have similar OLED features.

In contrast to the larger Eurocom Sky series of desktop replacements, the Eurocom Nightsky series consists of more traditional gaming laptops with many features users have come to expect from a high-end offering including per-key RGB lighting, narrow bezels, and GeForce RTX graphics. Our test unit today is the highest-end configuration of the 15.6-inch Nightsky RX15 equipped with an unlocked Core i9-9980HK CPU, 4K UHD OLED display, and GeForce RTX 2070 graphics.

The Nightsky RX15 Clevo PB51RF chassis is identical to the Nightsky Ti15 and so we recommend checking out our existing review on the Nightsky Ti15 here to learn more about its port options, serviceability, keyboard, speakers, and other physical features. For this review, we'll be focusing on the performance and OLED display of the Nightsky RX15 to see how they compare to the base Nightsky Ti15 configuration. Direct competitors in this space include other mid-size 15.6-inch gaming laptops like the Lenovo Legion Y740, Dell Alienware m15, Asus ROG GL531, and HP Omen 15.

See the product page of the Nightsky RX15 here for the full configuration options and price range.

Display

OLED offers a number of advantages - and disadvantages - when compared to the IPS option on the Nightsky series. It's 20 percent brighter with significantly deeper colors, pitch dark blacks, a higher native resolution, and almost no ghosting. Furthermore, the glossy overlay allows for crisper texts and images especially when compared to matte 4K UHD IPS panels. The result is a picture quality that is noticeably superior to even the best 15.6-inch laptop IPS panels currently in the market. The differences are perceptible to the naked eye.

A major drawback to OLED laptops at the moment is that the panel is limited to a refresh rate of only 60 Hz. The latest 144 Hz and 240 Hz IPS panels feel smoother and more responsive as a result especially when playing fast-paced games.

It's important to note that Samsung is currently the only mass market supplier of 15.6-inch 4K UHD OLED panels for laptops at the time of writing. Thus, this same Samsung SDCA029 controller or panel can also be found on the XPS 15 7590, Gigabyte Aero 15, Alienware m15, and Razer Blade 15 for very similar visual experiences between them.

Eurocom advertises 100 percent DCI-P3 coverage not unlike other 15.6-inch OLED laptops in the market with the same Samsung panel. Our own measurements show 88 percent 3D coverage of the AdobeRGB standard with a large portion of the color space not overlapping AdobeRGB since DCI-P3 is wider than AdobeRGB.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
2.6 ms ... rise ↗ and fall ↘ combined↗ 1.3 ms rise
↘ 1.3 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 8 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
2.4 ms ... rise ↗ and fall ↘ combined↗ 1.2 ms rise
↘ 1.2 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 6 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (33.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 59.5 Hz ≤ 100 % brightness setting

The display backlight flickers at 59.5 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 59.5 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

Much like what we discovered on the XPS 15 7590 OLED and Razer Blade 15 OLED, the Nightsky RX15 OLED exhibits similar PWM behavior that changes depending on the brightness level. At 49 percent brightness and up, frequency is stable at 59.52 Hz while frequency changes abruptly to 235.8 Hz when set to 48 percent and below. This behavior is not observed on laptops with IPS panels.

Outdoor visibility is better than the matte IPS panel on the Nightsky Ti15 when under shade. When under sunlight or on an overcast day, however, outdoor visibility is not any better or worse than the aforementioned Nightsky Ti15 due to the heavier glare on the glossy OLED screen. The wide viewing angles are identical to the Dell XPS 15 7590.

Annoyingly, display brightness will sometimes automatically drop to the minimum when the system is waking from a sleep state. You'll have to manually adjust the brightness each time to fix the issue.

Performance

No DPC latency issues
No DPC latency issues

The Nightsky RX15 is one of the few 15.6-inch laptops with an unlocked Core i9-9980HK option. Strangely enough, its GPU currently maxes out at the GeForce RTX 2070 instead of the RTX 2080 despite having the fastest mobile Coffee Lake-H CPU available.

LatencyMon shows no DPC latency issues as expected from a Clevo system. Laptops from major OEMs like Dell, HP, and others are more likely to have undesirable background activity and bloatware.

Processor

The Core i9-9980HK is unquestionably fast, but it's a mixed bag relatively speaking because of its steep drop in raw performance after maximum Turbo Boost ends. As shown by our CineBench R15 Multi-Thread loop graph below, CPU performance drops by 18 percent after the first two loops and never recovers thereafter. Nonetheless, performance remains much faster than the Core i7-9750H and Core i9-9980HK in the Nightsky Ti15 and Dell XPS 15 7590, respectively, even after accounting for throttling.

Some laptops with the "slower" Core i9-9880H like the MSI GE75 9SG can run faster than than the Core i9-9980HK if they can maintain faster clock rates for longer when under stress.

See our dedicated page on the Core i9-9980HK for more technical information and benchmarks.

GPU Performance

The mobile GeForce RTX 2070 is performing exactly where we expect it to be relative to other gaming laptops with the same GPU. Users can expect performance to be about 15 to 20 percent slower than the desktop GeForce RTX 2070. Upgrading from the Nightsky Ti15 GTX 1660 Ti SKU will see a raw performance boost of about 36 percent. There is enough power to play any title at 1080p60 with most or all settings at maximum. 4K gaming is also possible albeit with most settings turned to Low or Low-Medium.

See our dedicated page on the mobile GeForce RTX 2070 for more technical information and benchmark comparisons.

System Noise

Fan noise when gaming is identical to the Nightsky Ti15 meaning that users get faster graphics performance from the Nightsky RX15 without necessarily running any louder. The fans will, however, ramp up faster to become loud more quickly when under heavy processing stress. At 53.7 dB(A), the Eurocom is louder than we would like even for a gaming laptop.

We recommend setting the system to Quiet mode if not gaming to prevent the fans from pulsing. Fan noise maxes out at 33.4 dB(A) when set to this mode.

Surface temperatures are nearly the same as on the Nightsky Ti15. When at maximum stress, surface temperatures are actually slightly cooler than expected since core temperatures are cooler as our next section will show. The WASD keys, NumPad, and palm rests remain cool no matter the load, but be sure to not block any of the many ventilation grilles on the sides or bottom.

Stress Test

We stress the system to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed running as high as 4.2 GHz for the first minute or so until hitting a core temperature of 83 C. Thereafter, clock rate and temperature drop to 3.3 GHz and 65 C, respectively, much like what we observed on the Nightsky Ti15 with the Core i7-9750H. There is thermal headroom for overclocking if desired.

When running both Prime95 and FurMark simultaneously, CPU clock rates can occasionally fall to just 2.4 GHz for very short periods which is unusual for a laptop. GPU temperature is also curiously much cooler than on the Nightsky Ti15 by about 12 C to explain the cooler surface temperatures above.

When running Witcher 3, CPU and GPU clock rates remain relatively steady with core temperatures not unlike the Nightsky Ti15 despite the faster hardware of the Nightsky RX15. The Asus Strix G531GW with the same RTX 2070 GPU runs slightly warmer at 77 C when under the same gaming load.

Running on batteries will limit performance. A 3DMark Fire Strike run on battery power returns Physics and Graphics scores of 10148 and 5553 points, respectively, compared to 22247 and 20434 points when on mains.

Energy Management

Power Consumption

When gaming, power consumption is relatively steady at about 192 W to be 36 percent more demanding than the Nightsky Ti15 with GTX 1660 Ti graphics. Perhaps not coincidentally, the RTX 2070 outscores the GTX 1660 Ti by 36 percent in the 3DMark Time Spy benchmark.

We're able to record a maximum consumption of 246 W from the medium-sized (~15 x 7.5 x 3 cm) 230 W AC adapter when running both Prime95 and FurMark simultaneously. After about 1 minute, consumption drops to the 150 W to 230 W range. Battery recharge rate becomes very slow when the CPU and GPU are at 100 percent utilization since power consumption can be so high relative to the output of the AC adapter. We would have preferred a higher watt output overhead since this system ships with an unlocked Core i9 CPU.

When running Prime95, consumption spikes to 145 W for the first minute before dropping and stabilizing at 100 W. This behavior mirrors our Turbo Boost clock rate observations and CineBench R15 graph above.

Note that the 230 W AC adapter here is larger than the 180 W AC adapter that ships with the less demanding Nightsky Ti15.

Battery Life

Real-world WLAN runtimes are nearly identical to the Nightsky Ti15 at about 3.5 hours even though the latter is the lesser equipped SKU. For this test, we set both systems to 150 nits while looping the same web pages until automatic shutdown. The higher power consumption of OLED versus IPS does not come into play until brightness settings are very high.

It's worth repeating that the 62 Wh battery is removable and easily replaceable unlike most other laptops these days.

Verdict

In review: Eurocom Nightsky RX15 OLED
In review: Eurocom Nightsky RX15 OLED

Many of our same conclusions about the Nightsky Ti15 apply here for the Nightsky RX15 including the difficult serviceability, excellent keyboard feedback, average battery life, great performance, and loud fans when gaming. We instead want to answer the question: Are the Core i9 and OLED worthwhile upgrades over the base Core i7 and IPS?

The most appropriate SKU will depend on your usage scenario. If you plan on using the Nightsky RX15 primarily for gaming at 60 FPS, then the Core i7 with either IPS or OLED will do the trick. If you're aiming for frame rates greater than 60 FPS, however, then the additional CPU horsepower of the Core i9 and faster native refresh rate of the 144 Hz or 240 Hz IPS panel will serve you better. For a mixed usage scenario between demanding professional workloads, multimedia playback, and gaming, the Core i9 and OLED SKU like the one we have here would be optimal. It's just too bad that servicing is more difficult than it needs to be for an enthusiast offering.

OLED offers noticeably deeper colors, deeper blacks, less ghosting, denser pixels per inch, a brighter picture, and crisper image quality than any current 144 Hz or 240 Hz IPS alternative. For hardcore competitive gamers who value very high frame rates, however, IPS is still the better option.
