Eurocom Sky X4C Core i9-9900KS Laptop Review: Unlocked Desktop Processor in a Mobile Form Factor

127 W Core i9 Intel inside. The three-year old Clevo P751DM2 chassis is beginning to show its age. While the system can handle Intel's latest Core i9 CPU, it can't fully exploit the high Turbo Boost potential of the processor without running at temperatures well beyond 90 C.

The Eurocom Sky X4C is a high-performance laptop with easy serviceability aimed at enthusiasts. Unlike most other laptops, it carries upgradeable LGA 1151 desktop CPUs and MXM GPUs for added versatility.

We had checked out the Sky X4C almost two years ago with the Coffee Lake Core i7-8700K CPU and Pascal GeForce GTX 1080 GPU. Our unit today comes equipped with the faster and newer Coffee Lake Core i9-9900KS and Turing GeForce RTX 2080. We recommend checking out our existing review on the Sky X4C as all our comments on the chassis and its features still apply.

Maintenance

Accessories and Warranty

The usual manuals, HDD/SSD screws, and Drivers CD are included with optional adapters, docks, and inverters. A one-year limited warranty applies with extensions of up to three years.

Display

Unlike the glossy 4K UHD 60 Hz panel on our 2018 SKy X4C, our latest unit comes with a matte FHD 144 Hz panel. The AU Optronics B156HAN07.0 panel here can also be found on both the Schenker XMG Ultra 15 and Gigabyte Aorus X5 v8 meaning that these three laptops share similar display qualities including the fast response times, good contrast ratio, and decent color coverage. When compared to the 4K UHD option, the FHD option exhibits less ghosting.

Heavy uneven backlight bleeding is present on our test unit as shown by the picture below. We recommend checking for this immediately as the light bleed can be distracting during video playback or other darkened applications.

Color space covers approximately 59 percent and 91 percent of the AdobeRGB and sRGB standards, respectively, to be similar to all other 15.6-inch 144 Hz panels currently in the market. The only other high refresh rate panel that can offer a significantly wider gamut at the moment is the 120 Hz panel on the latest Razer Blade Pro 17.

The panel is not well-calibrated out of the box and color temperature is far too cool. Average grayscale and color deltaE values sit at 5.8 and 4.7 compared to 2.1 and 1.77, respectively, after calibrating the panel ourselves. Eurocom will pre-calibrate the laptop before shipping at an additional cost.

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
10.8 ms ... rise ↗ and fall ↘ combined↗ 5.2 ms rise
↘ 5.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 23 % 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
16.8 ms ... rise ↗ and fall ↘ combined↗ 9.2 ms rise
↘ 7.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 25 % 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 not detected

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.

Outdoor visibility is worse than the 4K UHD option since this FHD panel is dimmer. Viewing angles are still excellent except if viewing from abnormally wide angles where contrast and colors begin to degrade.

Performance

The Core i9-9900KS (S for Special Edition) is essentially identical to the Core i9-9900K with a couple of differences as described by their respective product pages here. From a pure performance point-of-view, the Special Edition SKU has a higher base clock rate of 4 GHz compared to 3.6 GHz on i9-9900K. In practice, however, the two CPUs perform nearly identically on laptops due to having similar Turbo Boost clock rate potential.

LatencyMon shows no DPC latency issues when the wireless is enabled or disabled. G-Sync is supported since there is no Optimus.

 

Processor

The octa-core Core i9-9900KS offers approximately 45 percent faster multi-thread performance than both the hexa-core Core i7-8700K on our older Sky X4C and the Core i9-9980HK in the latest Apple MacBook Pro 15. Nonetheless, raw performance is only within 1 to 2 percent of the Core i9-9900K. Performance sustainability is good, but we think it could be a little better; running CineBench R15 Multi-Thread in a loop results in an 8 percent dip in performance over time. The more massive MSI GT76 is able to sustain faster clock rates for longer with the "slower" Core i9-9900K as shown by our graph below.

GPU Performance

At stock, the GeForce RTX 2080 in our Eurocom is about 6 to 8 percent slower than the same GPU in the overclocked Dell Alienware Area-51m. A "proper" desktop RTX 2080 can offer about 8 to 15 percent faster performance than our Eurocom GPU.

See our dedicated page on the mobile GeForce RTX 2080 for more technical information and benchmark comparisons. Nvidia is expected to launch mobile Super options for laptops in 2020.

Emissions

System Noise

It would be unrealistic to expect quiet fans considering the 15.6-inch form factor and high-end components inside. When running demanding loads like games, fan noise can be as high as 55 to 59 dB(A) to be louder than most gaming laptops and on par with the MSI GT76 Titan. Even the Alienware Area-51m with the i9-9900K and overclocked RTX 2080 runs quieter (51 dB(A)) when under similar conditions.

The good news, however, is that the Eurocom is quiet when you expect it to be quiet and it's only loud when you expect it to be loud. For example, fan noise during low loads like web browsing or video streaming top out at only 31.7 dB(A). The fans may pulse occasionally, but these are short-lived and not bothersome. Only when running very demanding loads will the fans begin to ramp up exponentially in noise.

We can notice no coil whine or electronic noise from our test unit.

Temperature

Surface temperatures are never uncomfortabe despite the fast components inside. At worst, hot spots can become as warm as 51 C when under high processing stress. These spots are thankfully above the first row of keyboard keys where users are unlikely to touch. The middle of the keyboard can become as warm 42 C while the palm rests, WASD keys, NumPad, and touchpad remain relatively cool.

Stress Test

We stress the laptop with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU would spike up to 4.7 GHz and at a core temperature of 98 C for about 30 seconds. Afterwards, clock rates drop to about 4.4 GHz in order to maintain a slightly cooler core temperature of 88 C. While there is thermal overhead for overclocking, the gap is so small that you won't be able to squeeze much more out of the Core i9-9900KS in practice.

Note that the CPU and GPU do not share heat pipes unlike on most other gaming laptops. GPU temperature idles at just 41 C while the CPU can be over 90 C to allow for independent overclocking. In this case, the GPU will have better overclocking potential than the CPU as it averages around 80 C when under extreme loads. Overall, users can expect >80 C when gaming on this particular Sky X4C SKU.

Running on battery power will limit performance. A Fire Strike run on batteries returns Physics and Graphics scores of 13000 and 13973 points, respectively, compared to 24327 and 25497 points when on mains.

Energy Management

Power Consumption

The more powerful i9-9900KS and RTX 2080 come at a cost. When compared to last year's Sky X4C with the i7-8700K and GTX 1080, our newer Sky X4C consumes 50 percent more power (172 W vs. 258 W) when gaming. We're able to measure a temporary maximum consumption of 398 W from the large (~20 x 10 x 4.3 cm) 330 W when running both Prime95 and FurMark simultaneously. This eventually falls and stabilizes at 335 W meaning that you won't be able to both recharge the system and run extreme loads at the same time.

When running Prime95 only, consumption will spike to 233 W for about 30 seconds before falling and stabilizing at 166 W thereafter. This behavior mirrors our Prime95 stress test observations above where clock rates would only be fastest during the first 30 seconds before eventually falling.

Battery Life

Runtimes from the removable 82 Wh battery remain about the same as our 2018 Sky X4C. Users can expect just over 2.5 hours of real-world WLAN use before automatic shutdown. Charging from empty to full capacity takes about 2 hours.

The system cannot be recharged via USB Type-C.

Verdict

In review: Eurocom Sky X4C. Test unit provided by Eurocom
In review: Eurocom Sky X4C. Test unit provided by Eurocom

The original Core i9-9900K didn't have much overclocking headroom and so it's unsurprising that the Core i9-9900KS is no different. At stock, the Core i9-9900KS in the Sky X4C will stabilize at 4.4 GHz and 88 C or just 400 MHz above the base clock rate of the processor. Larger laptops like the Alienware Area-51m and MSI GT76 with the i9-9900K are able to match or outperform the i9-9900KS in our Eurocom. As versatile as this three-year old Clevo chassis may be, the Core i9 series is pushing it to its limits with not much room to spare. It's about time for Clevo to update this system to better exploit the high Turbo Boost potential of Intel Core i9 CPUs.

From a gen-to-gen perspective, the i9-9900K and 9900KS are about 35 to 45 percent faster than the i7-8700K and i7-9700K. You can still benefit from upgrading to a Core i9 in this regard, but just don't expect much CPU overclocking potential on the Sky X4C laptop.

Super fast, but also super warm. Configuring a laptop with the Core i9-9900KS is more about bragging rights especially when the original Core i9-9900K performs very similarly. The Eurocom Sky X4C is able to run the i9-9900KS stably at a clock rate 10 percent higher than the base clock rate even though the CPU is capable of more on a proper desktop.
