Acer ConceptD 5 CN515-51 laptop review: Kaby Lake G lightweight struggles with cost cutting

White featherweight. Acer leaves known paths with its ConceptD 5 CN515-51 to differentiate itself from the competition, with especially lightweight materials, Kaby Lake G with an integrated AMD GPU and a 4K UHD screen that covers a wider color gamut. At the same time, the Acer ConceptD CN515-51 is also cheaper than other multimedia laptops with a 15.6 inch screen. Unfortunately, the necessary cost cuts are showing up quite fast in this comprehensive review.
Benjamin Herzig, 👁 Sebastian Jentsch, Felicitas Krohn (translated by Benjamin Herzig),

Acer once managed to become the second biggest PC manufacturer with a budget-laptop-strategy. This is already 10 years ago now. From the peak with 13.9% market share in 2010, it has been a steady decline. In 2019, roughly 6% of all PC sold had the Acer logo on them. The strategy "quantity over quality" has been binned a long time ago. Instead, Acer tries to tackle the profitable mobile workstation and multimedia market with its new brand "ConceptD".

The Acer ConceptD 5 CN515-51, which we review today, definitely falls more into the multimedia and not in the workstation category. It contains no dedicated GPU. Instead, Acer bets on the Intel Core i7-8705G, which includes the AMD Radeon RX Vega M GL. In addition to this main processing pair, the ConceptD contains 16 GB RAM, a 512 GB SSD and a 15.6 inch 4K UHD screen. This configuration of the Acer ConceptD 5 CN515-51 costs €1,600 (~$1729). 

As the competitors for our comparison, we use the recent Dell XPS 15 7590, the Apple Macbook Pro 16 as well as the Lenovo ThinkPad X1 Extreme Gen 2. These three 15.6 inch laptops are among the top devices of this class and can be seen as a benchmark.

Lightweight chassis: Acer laptop prioritizes low weight

Acer ConceptD CN515-51
Acer ConceptD CN515-51

The Acer ConceptD CN515-51 looks different from many other recent multimedia laptops. The color alone is unusual, as the Acer laptop is completely white. That certainly sets it apart from the bulk of silver-gray and black laptops. If this coloring is good or bad depends entirely on taste.

Acer also goes its own way when it comes to the construction of the Acer ConceptD notebook. Aluminum is nowhere to be found. Instead, the Acer laptop is partly made out of plastic, partly out of Magnesium (a mix of Magnesium-Aluminum as well as Magnesium-Lithium). The plastic has a smooth surface and it is being used on the display-cover, display-bezels and the bottom cover. The palmrest is made out of white-painted Magnesium, which feels a lot like plastic.

In terms of quality, this solution is only partly good. Workmanship is good, but the stability of the display lid is not great. It is easy to twist it and pressure on the back of the display lid is directly visible on the LCD panel. For a laptop of this class and price, this is not appropriate. At least the Magnesium palmrest is completely stable.

The hinges are smooth-running and allow users to open the lid with one hand. They also permit an opening angle of 180 degrees. Unfortunately, the hinges are not stiff enough to prevent the screen from wobbling in situations like train-rides.

The lightweight construction pays off when it comes to weight, as the Acer ConceptD laptop is clearly lighter than the competitors. Only the more expensive ThinkPad X1 Extreme, which partly uses Carbon-Fiber as a material, is close in terms of weight. But even in this case, there is still a 200 g (~7 oz) difference. In terms of size, the Acer Notebook has no advantage. The Dell XPS 15 7590 is the benchmark in this category.

Connectivity: Thunderbolt 3 is missing from the Acer ConceptD

Different from the Apple Macbook Pro 16, Acer still offers plenty of legacy ports like USB type A and HDMI with the ConceptD CN515-51. Also, there is a dedicated, proprietary charging port. Disappointing is the USB C port: It can be used to charge the Acer laptop, but it does not support Thunderbolt 3. This feature should not be missing from such an expensive multimedia laptop.

SD card-reader

The SD card-reader is exposed as an extremely slow model in our benchmarks with the Toshiba Exceria Pro SDXC 64 GB UHS-II reference-card. Such a slow card-reader is only suitable for an extremely cheap laptop. With the target market of this laptop in mind, this cost-cutting measure is clearly misguided. For photographers, the card reader is much too slow; the models used in the ThinkPad X1 Extreme and XPS 15 are more than twice as fast.

Communication

The chosen Wi-Fi card is surprising, as Acer still uses the year old Intel Wireless-AC 7265. Accordingly, users have to do without Wi-Fi 6 / Wi-Fi AX. The performance of this old 2x2 module is not up to par anymore. Especially receiving data was slow. Also, the Wi-Fi card only supports Bluetooth 4.2.

Accessories

Apart from the 90 W charger, there are no other accessories in the box.

Maintenance

Eleven Torx screws have to be removed and many clips have to be opened before the base-cover of the Acer ConceptD laptop can be removed. Under the cover, there is a lot to do: The battery is replaceable and the cooling system is cleanable. Upgrading the RAM is not possible, however, as it is soldered on. At least, the SSD can be upgraded. There is also another free M.2 2280 slot, allowing for easy and cheaper upgrades. The Wi-Fi module is not soldered either. It should be possible to put in a Wi-Fi AX module later.

Warranty

The Acer ConceptD comes with a two-year bring-in-warranty. In the case of damage, it is necessary to send in the laptop.

Keyboard

Just like the rest of the Acer ConceptD CN515-51, the Chiclet keys are completely white with black lettering. They have an orange backlight, another unusual coloring choice.

In terms of quality, the keyboard is good enough for productive usage. The keys have enough travel and resistance, though its pressure-point is rather too soft. In no part of the chassis does the keyboard have any flex to it. The layout of the keys is OK too, thought the vertical arrow keys are somewhat too small. There is no numlock.

Touchpad

The touchpad measures 10.6 x 7.8 cm (~4.2 x 3.1 in). It has a smooth surface, which offers an ideal amount of slipperiness. Thanks to the Windows Precision drivers, the software support of the touchpad is nearly perfect. Only scrolling is sometimes a bit jittery, as it is sometimes miss-recognized as zooming.

Since there are no dedicated keys, the touchpad is depressable in the lower area. The integrated mechanism of the clickpad offers a crisp pressure-point, though this also results in comparably loud clicks.

4K UHD display: Strong color gamut meets worse than promised brightness

No doubt, the 4K UHD (3,840 x 2,160) IPS screen of the Acer ConceptD CN515-51 is meant to be the heart of the laptop. The 15.6 inch screen has a matte surface and is supposed to reach a brightness value of 400 cd/m².

Unfortunately, our measurements tell us otherwise. The screen misses the mark quite clearly with just 328 cd/m². The panels of the competitors all manage more than 400 cd/m².

Another weakness of this LCD screen: Backlight bleeding. This phenomenon is especially irritating in darker software environments. Apart from that, the slow response times are also noteworthy in a negative way.

Even ex-factory, there are little to no deviations in terms of color accuracy. The contrast of 1321:1, which is due to the low black-value of just 0.265 cd/m², is commendable. The quality in terms of the colors is excellent, which might be connected with the color gamut as well. The sRGB gamut is completely covered and AdobeRGB almost completely (88%). This wide gamut panel is definitely suitable for color-critical work.

Using the Acer ConceptD CN515-51 is definitely possible, thanks to the matte surface of the screen and the acceptable brightness. This is not true if the sunlight shines directly onto the screen, however.

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
40 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 16 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 97 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
63 ms ... rise ↗ and fall ↘ combined↗ 32 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 97 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.7 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17531 (minimum: 5 - maximum: 2500000) Hz was measured.

We can not complain about the viewing-angle-stability of this IPS panel.

Performance: Acer laptops not really on a workstation-level

Acer makes buying the ConceptD 5 CN515-51 easy for German customers, as there is only a single configuration available. It contains the Intel Core i7-8705G, the AMD Radeon Vega M GL as well as a 512 GB SSD and 16 GB DDR4-2400 RAM. The RAM is soldered and not upgradable, which is a huge drawback for an expensive multimedia laptop.

Processor

The Intel Core i7-8705G is a quad-core processor with a TDP of 65 W based on the Kaby Lake G series. The four cores have a base-clock of 3.1 GHz and a Turbo clock of 4.1 GHz. Comparisons with other processors are possible through our CPU comparison list.

The CPU on its own consumes a maximum of 42 W in the Cinebench multicore test. After a while, the consumption stabilizes at 32 W in the Cinebench loop. There is no throttling beneath the base clock. Still, the Acer ConceptD 5 CN515-51 can not compete with the other multimedia laptops. The six-core CPU of the Lenovo ThinkPad X1 Extreme 2019 is roughly 21% faster. The eight-core chips of the Dell XPS 15 7590 and the Apple Macbook Pro 16 are 61 to 77% faster.

While using the device on battery, only half of the CPU performance is available.

Mass storage

The single M.2 2280 SSD has a capacity of 512 GB and was made by Western Digital. Its performance in our benchmarks is good. This fast PCIe NVMe SSD only has to bow down before the even faster Samsung PM981.

GPU

The integrated AMD Radeon RX Vega M GL serves as the main GPU. That a GPU of an Intel processor is made by AMD is still something relatively rare. It is what makes Kaby Lake G special. The GPU has 1,280 shader-units with a maximum clock-rate of 1011 MHz. Compared with integrated Intel GPUs, the AMD Vega chip is a lot faster, but it still lags behind dedicated Nvidia GPUs. The difference is not huge though. 

Just like with the processor, there is a performance limitation for the GPU as well. Instead of roughly 10,000 points, the Acer laptop only scores 5253 points in the 3DMark 11.

Gaming performance

Gaming is definitely possible with the Radeon RX Vega M GL. Even recent games are playable on medium to high settings in FHD (1,920 x 1,080). Gaming in 4K UHD however is not possible, despite the internal screen. For that, a lot more GPU power would be necessary.

Noise

The Acer ConceptD 5 CN515-51 contains two fans. They are completely disabled while the device is idling. Under load, they do run at a moderate loudness of 32.6 dB(A), though they also reach a loud 40.2 dB(A) at their peak. That is not a huge problem, since this only happens under peak load. More annoying is the constant coil whine, which is clearly audible.

Temperatures

stress test (Prime95 + FurMark)
stress test (Prime95 + FurMark)

The heat concentrates on the left side of the Acer laptop. At most, we measure 45.4 degrees Celsius (113.72 degrees Fahrenheit), which is completely OK for a comparably powerful and thin laptop.

In the stress test with Prime95 and FurMark, the CPU clock-rate is reduced to 800 - 1,000 Mhz, which means the CPU only consumes 8 W. At the same time, the GPU does not have to reduce its clock-rates in any way. The CPU temperatures rise to a maximum of 74 degrees Celsius (165.2 degrees Fahrenheit) in the stress test. The TDP throttling should not affect everyday usage. In the 3DMark test, which we performed directly after the stress test, we managed to achieve a normal result.

Speakers

The speakers deliver a mediocre performance. They are not loud enough, especially compared with the Dell XPS 15 7590. Instead, the combo audio port should be used. It puts out good quality sound.

Power management

Wasting energy. These two words describe the power management of the Acer ConceptD 5 CN515-51 very well. The minimum (!) power consumption of 12 W is extremely high.

For the maximum consumption of 87 W, the 90 W charger is more than enough.

Battery life

charging time: 115 minutes
charging time: 115 minutes

By a mile, the battery of the Acer ConceptD 5 CN515-51 is the smallest in the comparison of the 15.6 inch multimedia laptops. Only 48 Wh are available. That is a minuscule amount, especially for a laptop for a 4K UHD screen. The result of this small capacity: A weak battery life of just 4.5 hours. The Lenovo ThinkPad X1 Extreme 2019 performs almost as bad, despite its bigger battery, but the competitors from Dell and Apple have a much better endurance.

Acer has created an unusual multimedia laptop with the ConceptD 5 CN515-51.

It looks different from other models of this class and has a strong focus on a low weight, thanks to its chassis materials. That is a good thing, but the weak screen lid seems to be a negative side effect of this focus on a low weight. As for the ports, Acer did not include Thunderbolt 3. Also, an extremely slow SD card-reader is used, which is completely misplaced in a multimedia laptop that expensive. The same is true for the outdated Wi-Fi module, which doesn't even support the newest Bluetooth standard. Both commendable and objectionable is the upgradability: While the RAM is completely soldered, the mass storage capacity can be upgraded quite easily, thanks to the free M.2 2280 slot.

The screen of the Acer notebook has a great color gamut coverage, its lower than promised brightness and relatively strong backlight bleeding do disappoint us though. In terms of performance, the ConceptD delivers roughly what we were expecting of Kaby Lake G. A good performance for a multimedia laptop, but many other laptops with newer Intel CPUs and dedicated Nvidia GPUs do deliver better performance. Unfortunately, this does not result in better battery life in return. Instead, the battery ruins the equation, since it is too small. Also, we have to negatively weigh in the coil whine, the performance limitation when the device runs on battery power and the worse than average speakers (for a multimedia laptop).

Not without compromises: Acer unfortunately decided to cut costs at crucial components. It can not compete with the more expensive competitors.

For us, it is unclear to whom Acer wants to market the ConceptD 5 CN515-51. The most prominent positive feature is the low weight and then the colorful screen. With these two strengths, it seems to be destined to be a photographers dream. This group however will probably be extremely annoyed by the slow SD card reader. Also, the low battery life is a problem on the go. The ConceptD can be used to play games, but it is not really made for that either.

In 2010 I started to get more and more involved with technology, especially notebooks have been my passion ever since. Of course I came across the detailed tests of Notebookcheck very quickly. With time I learned more and more about notebooks and started writing small reviews about notebooks in forums and blog pages. To earn some extra money during my studies I turned my hobby into my profession and joined the team of Notebookcheck in 2016. My personal interest is especially in business notebooks.
