Schenker XMG Apex 15

Schenker's own online shop bestware.com offers numerous configuration options for the Apex 15. While the screen remains an IPS panel with 144 Hz (no G-Sync), buyers can choose between a GeForce RTX 2060 and a GeForce RTX 2070. 

The core element of the Apex 15 - the processor - can also be chosen according to your wants and needs. The basic offer includes a Ryzen 5 3600 (6 cores). More money will get you a Ryzen 7 3700X (8 cores), a Ryzen 9 3900 (12 cores) or a Ryzen 9 3950X (16 cores). The surcharge is minimal for all upgrades save the last. The device can be equipped with up to 64 GB of DDR4 RAM and up to three storage devices (2x M.2, 1x 2.5-inch). Buyers can also have a say on the network module, the keyboard, the heat-conducting paste and the operating system.

The price of the Apex 15 starts at around 1300 Euros (~$1400). Our test configuration, equipped with a Ryzen 9 3900, a GeForce RTX 2070, 2x 8 GB of RAM and a 1-TB SSD, is currently available for around 2000 Euros (~$2160).

Case

Unlike the XMG Ultra 15, which is rather large and heavy due to its height of 3.8 cm and a weight of 3.5 kg, the Apex 15 - which, by the way, features a slim bezel design - is fairly compact. It has a height of 3.25 cm and weighs 2.7 kg. Its dimensions are similar to those of the Eurocom Nightsky RX15, which also has a similar exterior in general. This is no surprise since both cases come from the barebone expert Clevo. The Apex 15 is based on the case NH57AF1. 

The 15-inch notebook gives a fairly good impression in terms of quality. While the lid is made of metal, the base unit consists of plastic. The workmanship is satisfactory and all elements come together nicely apart from one or two small details. The hinges are unobtrusive as well and the maximum opening angle of around 130° is typical for a standard notebook.

The Apex 15, like most Clevo barebones, does not try to make a bold design statement but has a rather subtle appearance. Only the line design of the lid might give away who this device is designed for. We only found one weak point in terms of stability: the lid. Like with many gaming laptops, the display can be warped quite strongly. The base unit on the other hand hardly gives way under strong pressure.

Connectivity

Ports

Apart from the missing Thunderbolt 3 port, which really is a must-have in this price range, the port selection is very satisfactory. There's a Kensington lock and an RJ45 port, one USB 2.0 and three USB 3.1 gen 2 ports, one of which is Type-C and supports DisplayPort.

Talking of image output: External monitors can also be connected via the HDMI 2.0 port or the dedicated Mini-DisplayPort. If you include the integrated display, you could theoretically have a quad-screen setup. The multimedia offering is completed by two audio jacks (one for headphones, one for a microphone) and an SD card reader, which was kept in the small micro format despite having ample space available. 

As some of the ports are positioned along the back of the notebook and there are only a few connectors in the front half, users will have sufficient space for using an external mouse comfortably.

Communication

We would recommend upgrading the network module during configuration in order to receive maximum Wi-Fi range and speed. The Wi-Fi module in our test unit is the Intel Wi-Fi 6 AX200. It is not a lot more expensive and covers all modern features such as 802.11ax and Bluetooth 5.0. Please note: The results of the Wi-Fi test displayed below cannot be compared to those of the competition due to the recently updated router (Netgear Nighthawk AX12 instead of Linksys EA8500). The Apex 15 reaches more than 1300 Mb/s, which is a very good result.

Accessories

Schenker has equipped the notebook with a fair amount of accessories. Apart from a quick-start guide, a DVD with drivers on it, a USB stick with software and a tube of heat-conducting paste, we also found an enormous mouse pad. The device also comes with a 230-W power supply that weighs around 700 g and is 15 x 7 x 3 cm large. 

Maintenance

"Finally a notebook with good maintenance options" - that was the thought that went through our head after a look at the bottom of the laptop. Instead of having to remove the entire bottom cover with numerous screws and clips, the barebone manufacturer chose to include a large maintenance hatch that easily slides open after removing seven Phillips screws. The battery is directly accessible from the outside, which has also become a rare sight nowadays.

Buyers will continue to be pleased with maintenance options once they're inside the case. Thanks to its origins as a desktop chip, the processor can be exchanged if necessary (the GPU, however, is soldered on). The strong cooling system consists of several metal surfaces and two fans with three heat pipes leading away from each. Users can easily exchange the RAM modules and storage devices.

Warranty

The basic warranty covers 24 months (6 months fast repair). If you want to be on the safe side, you can extend the warranty to 36 months of fast repair.

Input Devices

Keyboard

Clevo has again chosen its standard chiclet keyboard, which we find has a good layout. Apart from the narrow number block and row of F keys, all keys, including arrow keys, are decently sized.

Typing is very comfortable on this device and the keys are the right balance between soft and hard. However, we would like to mention that there is significant keyboard clatter. Night owls will be pleased by the keyboard backlighting, which offers several colors and levels of brightness. The maximum brightness could be a bit more intense, however.

Touchpad

The device features a classic touchpad with dedicated mouse keys (which feel rather cheap and loud when clicked). The touchpad itself is around 11 x 6.2 cm large and has a smooth finish. Nonetheless, gliding isn't ideal, particularly when your fingers are wet or oily. Apart from that we were quite happy with the touchpad and its precision and gesture support (zooming, scrolling) worked well.  

Display

Perhaps unsurprisingly, the Apex 15 is equipped with a matte Full-HD IPS display. Thanks to its 144 Hz, even normal Windows applications feel a lot smoother (cursor movements!). The 15-inch display is just as fast while gaming and has a response time of 11.2 ms (black-to-white) and 17.6 ms (gray-to-gray). This means that even fast games will be displayed smoothly for the most part. Most buyers should be satisfied with this display.

* ... smaller is better

The panel was manufactured by AU Optronics (B156HAN) and offers not only short response times but also a good contrast ratio of 1130:1. The black value is good as well at 0.28 cd/m². We measured an average brightness of 316 cd/m², which is suitable for a high-end notebook, albeit not phenomenal. (Using devices outdoors only really becomes comfortable from around 400 cd/m².)

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
11.2 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 5.2 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 0.8 (minimum) to 240 (maximum) ms. » 12 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.7 ms).
       Response Time 50% Grey to 80% Grey
17.6 ms ... rise ↗ and fall ↘ combined↗ 9.2 ms rise

The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (39.2 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: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18115 (minimum: 5 - maximum: 2500000) Hz was measured.

Testing Conditions

Clevo's so-called Control Center is the central controlling software in this device. It has a very clean design and offers various tuning options. There are two menus for the keyboard (backlighting, macros, etc.) as well as a menu for power profiles and one for fan behavior. As the cooling system was rather disappointing in this device (more on that later), we decided not to stick to the same mode for all our tests, but rather to switch between quiet (idle) and performance (load) mode depending on the scenario.

Performance

With its CPU socket, the Apex 15 definitely belongs in the category of desktop replacements. The ample number of cores combined with a high-end GPU, a PCIe SSD and at least 16 GB of RAM mean this device should be future-proof for quite some time.

Processor

While the Intel processors used in notebooks usually max out at 8 cores, the AMD CPUs in the Apex 15 offer 6 to 16 cores. The Ryzen 9 3900 in our test unit is a 12-core model that can work up to 24 threads simultaneously via SMT and has a TDP of 65 W - that's quite low for a desktop processor. The clock rates according to AMD are between 3.1 and 4.3 GHz.

We tried to find out how the turbo fares with the help of our Cinebench loop (see graph). The fact that the clock rate dropped slightly after the initial round is quite normal. During Cinebench R15, the Ryzen 9 3900 clocked at 3.4-4.2 GHz under single-core load and at an average of 3.6 GHz when all cores were under load. That's a decent result. (The clock rate dropped to 2.8 GHz with the Control Center set to entertainment mode.)

The potential of this device becomes even more apparent during the remaining obstacle course of benchmarks. The multi-core Cinebench R15 places the Ryzen 9 3900 at around 50% above the Core i9-9980HK (Eurocom Nightsky RX15) and 90% above the Core i7-9700K (Schenker XMG Ultra 15). The advantage compared to the i9-9880H is 75% (MSI GE65 Raider 9SF) and 100% (Asus Strix G531GW). If you require a lot of processing power, you're in the right place.

System Performance

As expected, the Apex 15 is number one in our list of comparison devices when it comes to system performance. It reached 6883 points in our PCMark benchmark, which is 18% more than its competitors. However, Schenker and Clevo could further improve the boot process as it's a little slow for a laptop equipped with an SSD.

Graphics

In line with our high-end CPU, this device also features a high-end GPU. The surcharge for switching from an RTX 2060 to an RTX 2070 is definitely worth the extra money. While the former is primarily made for Full-HD displays, the latter is often powerful enough for QHD and 4K displays. It also has 2304 shader units rather than the 1920 found on the RTX 2060 and 8 GB rather than 6 GB of GDDR6 VRAM (storage interface: 256 vs. 192-bit).

The base clock rate of the Turing chip is 1260 MHz. However, thanks to the automatic GPU boost, the chip reaches considerably higher clock rates in practice. The chip in our test unit settled down at around 1680 MHz during the Unigine Heaven benchmark and also offered a similar result during our benchmark with The Witcher 3, which we run at maximum details for around 60 minutes. The relatively constant frame rates in the lower graph show that the GPU performance remains the same over long periods of load.

We did not notice any anomalies during our benchmark check. The 3DMark 11 and the current 3DMark tests place the Apex 15 at the top of the comparison field in most scenarios. It's a shame that Schenker hasn't (yet) included the faster Super version of the RTX 2070 as an option.

Gaming Performance

The RTX 2070 can display every game smoothly at maximum settings in native resolution. Even demanding games such as Borderlands 3 are a piece of cake for this chip and frame rates reach over 60 FPS on average. Games that are less demanding or more optimized, such as Doom Eternal, can really make the most of the 144-Hz screen.

System Noise

The Apex 15 has set a new negative record in terms of system noise. We measured 62 dB(A) during The Witcher 3, which is the highest value we have ever measured in this scenario. The noise level is very loud, even when using a headset - buyers will have to have strong nerves. While the device is quieter in entertainment mode, we personally still find it too loud (around 50 dB(A) after the BIOS-update)

We would highly recommend using the quiet mode when working in idle. Otherwise, users will be confronted not only with a loud basic noise level but will also have to deal with occasional exaggerated rpm increases that cause higher noise levels than many gaming notebooks produce under maximum load. The quiet mode makes the Apex 15 more or less bearable while idling (35 to 39 dB(A)). 

Clevo really should take another close look at power management and cooling fan behavior. The way it is now, the Apex 15 feels like a device in the alpha or beta stage of development - not like a finished product (upon inquiry, Schenker promised improvements).

Temperature

The advantage of the high fan rpm is that the temperatures remain moderate - at least on the outside of the device. We measured a maximum of 44 °C (top) and 48 °C (bottom) during our stress test using the tools FurMark and Prime95. This is fine considering the performance this device can offer, particularly because the wrist rest remains significantly cooler (below 35 °C).

Looking at the components, it's the CPU in particular that really works up a sweat. While the GeForce RTX 2070 reaches no more than 77 °C under maximum load, the Ryzen 9 3900 gravitates towards 90 °C despite throttling to around 2.2 GHz. These results lead us to conclude that the Ryzen 9 3900 is too strong for this notebook and cooling system. It is the sole component responsible for the bad results in terms of emissions (we can't even imagine what these might look like with the Ryzen 9 3950X). We would therefore recommend buyers to stop at the octa-core Ryzen 7 2700X. The 12 and 16-core models are more suited for the case of the XMG Ultra 15.

Speakers

Don't have too many expectations for the sound system, either. Compared to the XMG Ultra 15, which offers fairly good audio for a notebook, the Apex 15 lacks bass and also mids and highs (linearity etc.).

Energy Management

Power Consumption

Whether you put the blame on Clevo or AMD - the power-saving mechanisms of the Ryzen 9 3900 are modest to say the least. This becomes particularly apparent when looking at consumption while idling (total system). 60 W is a lot even for a gaming notebook with a desktop CPU. Intel devices usually consume a lot less. The XMG Ultra 15, for example, consumes a meager 40 W (Core i7-9700K). At least the consumption levels are fairly normal under load. 141-259 W is not that different to the XMG Ultra 15, which loses out due to its number of CPU cores.

Battery Life

Let's not talk about the battery life. Even under perfect conditions (no load, minimum luminosity) the 62-Wh battery hardly lasts an hour. A larger battery would only make a small difference due to the high idle consumption.

12 cores and 24 threads in a notebook: What sounds marvelous has some pitfalls in everyday use.

The meager energy-saving mechanisms of the AMD CPU mean that the Ryzen 9 3900 is very loud (3000 - 4000 rpm) and warm (60 - 70 °C) while idling and performing simple tasks such as watching videos or browsing the web. Fortunately, you can switch to quiet mode.

This is why we can hardly recommend the Apex 15 - although Schenker is planning a BIOS update. Better energy management and cooling fan control (entertainment and performance mode) would make this high-end newbie an interesting device for AMD fans. We know of no 15-inch notebook that offers as much CPU power as this one does. Most Intel models are a lot slower.

Growing up with MS-DOS and Windows 3.1 in the early 90s, I discovered my interest in computers in my childhood. Especially computer games radiated a great fascination for me even then. From Monkey Island to Lands of Lore to Doom, everything was gambled that you could get your hands on. I have been working for Notebookcheck since 2009 with focus on high-performance gaming notebooks.
