Schenker Technologies XMG U727 (Clevo P870KM-GS) Laptop Review

Florian Glaser (translated by Bernie Pechlaner), 03/17/2017

A tower PC dressed up as a notebook. While most manufacturers’ gaming laptops feature mobile processors and a soldered-on GPU, Schenker Technologies have taken a different route with their 17-inch XMG U727 and equipped the mammoth with a desktop CPU and an MXM graphics card. Whether this approach is successful or not is the subject of our review.

To emphasize the upgradeability of their latest generation, the German Notebook retailer Schenker Technologies refrains from a name change and simply calls the 17-inch notebook XMG U727 the same as its predecessor. To differentiate the new offering in their online shop, Schenker has simply added a "2017" to the name. Since the chassis is quite similar to that of the predecessor, we will forgo a detailed examination of the case, the connectivity, input devices and the speakers and will only briefly touch upon what is new under the hood.

We are already familiar with many of the components such as the graphics card. The user can choose a GeForce GTX 1080 or an SLI combo utilizing NVidia’s most powerful notebook GPU. The U727 supports a maximum of 64 GB DDR4 RAM (4 slots) and up to 5 storage drives (3x M.2 Typ 2280 PCIe 3.0 x4 & 2x 2.5-inch), which is also very generous. The display choices consist of a WQHD panel with 2560x1440 pixels running at 120 Hz and a UHD panel with 3840x2160 pixels at 60 Hz (both with G-Sync support).

The most significant change is the processor. Instead of a Skylake-generation CPU, both the (still available) 2016 version as well as the 2017 version are equipped with Kaby Lake units ranging from the cost effective Core i5-7400 (max. 3.5 GHz, 4 cores, 4 threads, TDP 65 W) to the very expensive Core i7-7700K (max. 4.5 GHz, 4 cores, 8 threads, TDP 95 W). And just as if desktop CPUs in a notebook were not unusual enough, Schenker has also started offering delidded processors now, which is something many users have been hoping for. 

Of course, performance like this does not come cheap: as configured (see the specifications), the laptop sells for 4400 Euros (~$4740); the least expensive version costs 2900 Euros (~$3125).

Overview

The 2017 version of the XMG U727 is based on the 870KM GS Barebone from Clevo, which is identical to the 2016 version (Clevo P870DM3-G) – including the physical ports. For this reason, we did not take a new set of photos, but reused the ones we shot during our previous review

At almost 5 kg (~11 lbs) and 4.7 cm (~1.85 inches) thick, the 17-inch notebook is still one of the heaviest and thickest gaming notebooks on the market. Nearly all GTX 1080 competitors - such as the Acer Predator 17 X (4.3 kg/~9.5 lb)), the MSI GT73VR 7RF (4.1 kg/~9 lb) and the Asus G701VIK (4.0 kg/~8.8 lb) - are both lighter and slimmer. These laptops come with a regular notebook CPU and are not as readily upgradeable and as easy to maintain.

Software

The software package is also almost identical to what was installed on the predecessor. Tuning fans will appreciate the Control Center, which not only allows manual fan control, but also makes it possible to change the keyboard colors and overclock the CPU, RAM, and the GPU. We conducted our tests with the notebook as it was shipped - without overclocking enabled.

In addition to the high resolution, the IPS display impresses with high color accuracy (DeltaE deviation < 3) and superb coverage of the color spaces: for a notebook, 100% sRGB and 88% AdobeRGB coverage are outstanding. Viewing angle stability, brightness (average: 344 cd/m²) and contrast (above 1000:1) also rate from good to very good.

Compromises are only necessary when it comes to the response times: 28 ms for the black-to-white and 44 ms for the gray-to-gray response are not exactly impressive when compared to 120 Hz notebooks (TN panels are generally much faster). OLED panels - like the one Dell uses for the Alienware 13 R3 - are of course much faster still.

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
28 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 22 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 30 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 61 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43.4 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: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5054 (minimum: 43 - maximum: 142900) Hz was measured.

Performance

We will start our performance evaluation with some screenshots depicting detailed information about the processor, the motherboard, the RAM, and the GPU.

Processor

The CPUs that Schenker use for their XMG U727 have - except for the power-saving versions ending in T - a much higher TDP of 65 to 90 W when compared to their mobile counterparts at 45 W. Although a desktop CPU in a notebook requires a sophisticated cooling system, it still makes a lot of sense. One of the main benefits: the CPU is upgradeable, since - unlike what we are used to from "normal" laptops -  it is not soldered onto the motherboard. This means that the processor can be swapped in case of a defect or for other reasons.

Another advantage is the faster clock speeds. While the top notebook CPU Core i7-7820HK tops out at 3.9 GHz, the Core i7-7700K reaches up to 4.5 GHz. The reason why many competitors (Acer Predator 17 X, Asus G701VIK, MSI GT73VR 7RF ...) are still able to keep up with the review laptop when it comes to the CPU benchmarks has to do with overclocking. Since the user can select the multiplier freely, the Core i7-7820HK can reach up to 4.0 GHz or more and thus only trails the faster Core i7-7700K by 5 to 11%.

The Turbo is utilized very well when it comes to both single and multi-core loads. The Kaby Lake processor never dropped below 4.4 GHz, even after prolonged periods of stress. A 30 minute test using our brand new Cinebench R15 loop resulted in very consistent scores.

System Performance

Although the overall system performance is of course top notch, the notebook did not score quite as well as expected when running the PCMark benchmarks - our configuration trailed the competition in both the Home and the Work sub-tests. The PCMark 7 score of 7864 on the other hand is good enough for second place right between the Asus G701VIK (7903 points) and the Acer Predator 17 X (7667 points), both of which also utilize an NVMe SSD. Subjectively, the system is pleasantly quick and impresses with very fast load times.

Storage Devices

To avoid bottlenecking the high-end components and to guarantee ample storage, Schenker utilizes a total of three hard drives. The 256 GB Samsung M.2 SSD houses the operating system (Windows 10 Home 64-bit). Based on PCIe 3.0 x4 technology, the SM961 literally mops the floor with conventional SATA III SSDs. According to AS SSD, the drive reaches up to 2746 MB/s and 1445 MB/s for sequential reads and writes, respectively - an outstanding result.

The secondary solid-state drive is faster still with read and write transfer rates of 3002 MB/s and 2066 MB/s, respectively. The 512 GB version of the Samsung 960 Pro that Schenker uses is currently the fastest storage option available. Users requiring even more space (movie collections, etc.) are going to appreciate the 2000 GB 5400 RPM Seagate Barracuda hard drive, which offers a great price-to-performance ratio.

GPU Performance

To justify the rather steep price, Schenker Technologies of course, make use of the most powerful laptop GPU at the time of writing. The difference between the GTX 1080 and the GTX 1070 is not quite as pronounces as it is between the GTX 1070 and GTX 1060. Gaming aficionados who want to use 4K at high settings cannot avoid the top-end GPU, however. As shipped, the Pascal-based GPU is not overclocked, so the XMG U727 slightly trails other GTX 1080 laptops with standard overclocking activated. The Asus G701VIK, for example, was about 7% faster when running 3DMark 11 and the 3DMark 13 Fire Strike test.

The XMG U727 utilizes the automatic Turbo of the GeForce GTX 1080 quite well. When we ran Unigine Heaven 4.0 Benchmark, the clock speed levelled out at 1660 MHz, which is right in the middle of the official Turbo range from 1582 to 1771 MHz. Under optimum conditions, the DirectX 12 GPU can top out at over 1900 MHz (GPU-Z render test).

Gaming Performance

Since we have encountered frequent criticism for our stress test - full load with FurMark and Prime 95 does indeed not simulate a very realistic scenario - we have now added a gaming test to our arsenal. To determine how a system reacts under load for extended periods of time, we run the open-world game The Witcher 3 Notebook Benchmarks (1920x1080, ultra) under controlled settings and record the clock rates, the temperature, the power consumption, the noise level, the battery performance and the frame rates with the notebook on external power. The last setting is shown below as a graph.

The Witcher 3 ultra

Aside from the initial period, during which the GeForce GTX 1080 runs at a slightly higher Turbo speed with frame rates of 70 to 74 fps, the notebook comfortably managed 60 to 70 fps during our test, which means that throttling is not an issue. When the XMG U727 runs on battery power, the performance decreases by about 30% and the frame rate drops to 57 fps. The GeForce GTX 1080 can handle most games at a resolution of 3840x2160 pixels and at high to maximum details. Only when we played games that are not optimized all that well - for example “Mafia 3” - the GPU was unable to cope with 4K.

System Noise

As far as the noise level is concerned, the Schenker notebook behaves much like other high-end laptops. During the 3DMARk 06 benchmark test, the XMG's output fluctuated from a clearly audible 39 dB(A) to a quite noisy 48 dB(A); during the stress test we recorded 52 dB(A). Gaming is not exactly quiet: when we ran our “Witcher 3” benchmark, the XMG U727 produced 51 dB(A) on average, which we found to be quite annoying without headphones - sensitive users in particular might be affected. When using 3D mode, the fans spool up rapidly, but take a while to settle down afterwards. Our review notebook was also affected by coil whine at certain load levels.

When idling, the laptop is surprisingly quiet. The fans are not spinning at all most of the time, so it is only the gentle swooshing sound of the HDD which is audible. Once the HDD turns off, the system  is almost silent. We did not encounter the rapid spooling-up of the fans during idle that many Clevo Barebones are afflicted with. When subjected to low loads (web, video), the notebook quite frequently reaches 40 dB(A), however.

Temperature

Gaming notebooks have one major weakness: the temperatures. The XMG U727 is no different and the internal components get quite hot under load. Despite the fact that the notebook's Core i7-7700K is delidded, we still recorded up 100 °C (~212 °F) during the stress test. Throttling was not an issue even though we observed occasional dips to 1.0 GHz. The cores dropped to about 4.0 GHZ only after we ran FurMark and Prime95 for about 60 minutes. The predecessor suffered from heavy throttling despite the less powerful CPU. The graphics card is a different story: although the GeForce GTX 1080 does not get quite as hot at 90 °C (~194 °F), its speed is reduced to 1100 MHz.

Users will not necessarily notice the high temperatures inside: 48 °C (~118 °F) on the top and 56 °C (~133 °F) on the bottom are certainly acceptable, given the huge amount of power. When we ran “The Witcher 3, we recorded an average of 37 °C (~99 °F) and 41 °C (~106 °F) for the top and the bottom, respectively. While idling, the chassis remains between 26 and 35 °C (~79 and ~95 °F), which is an acceptable result.

Energy Management

Power Consumption

Since the laptop utilizes desktop hardware, the power consumption is much higher than that of the mobile-CPU competition. While idling, the XMG U727 requires between 32 and 51 watts - the MSI GT73VR 7RF needs 29 to 40 watts and the Asus G701VIK only draws 24 to 38 watts. Laptops with Nvidia's Optimus technology (dynamic graphics card switching) remain under 30 watts on average. The draw of 350 watts at maximum load explains why Schenker had to include such a large and heavy (1.3 kg / 2.9 lbs) 330 watt power adapter. When running 3DMark 06 and “The Witcher 3”, the notebook required about 138 and 279 watts, respectively.

Battery Life

Considering the information we have provided thus far, it should not come as a surprise that the battery life is extremely modest. With a 3D run time of 1 hour and 37 minutes with the display at maximum brightness and an idle run time of 3 hours 42 minutes at minimum brightness, the XMG U727 does not exactly cover itself with glory. The 17-inch laptop lasted only 2 hours 48 minutes during the WLAN test - the competitors last at least 3.5 hours or longer.

Verdict

In review: XMG U727 2017. Test model courtesy of Schenker Technologies.
In review: XMG U727 2017. Test model courtesy of Schenker Technologies.

With its high weight (5 kg / 11 lbs), substantial thickness and - last but not least - exorbitant price, the XMG U727 from Schenker Technologies will appeal to only a very small number of notebook users.  

Demanding core gamers opting for this notebook will end up with an exceedingly fast high-end notebook suitable for nearly all conceivable tasks. The XMG U727 is very easy to maintain and upgrade; with its socket-based CPU, MXM GPU, four RAM slots and five storage drive slots, the 17-inch notebook is also quite future-proof. The port selection is also excellent and with 2x Thunderbolt 3, the technology is about as good as it gets.

The input devices are very good and the 4K display with G-Sync support is outstanding with the color space coverage in particular reaching reference level. Speaking of reference level: the sound quality is top notch - a rarity in the notebook sector. As far as the emissions (noise level, temperature) are concerned, the results are not outstanding, but at least they are average.

In short: fans of high-resolution displays who would like to play modern games in all their (graphics) glory will find the XMG U727 to be an exceedingly fast companion.

Ended up in the IT sector in the 90s more or less accidentally and have remained in the industry (as a sysadmin) ever since. Always been interested in laptops - first purchase was - if memory serves correctly - a Toshiba Satellite T2115CS with DX4-75 processor, 4 MB of RAM and 350 MB hard disk drive (and Windows 3.1). To this day, laptops appeal to me - much to the chagrin of my wife, who doesn’t seem understand why we need 5-10 of them at any given time ;-).
