For the original German review, see here.

The Nexoc G734IV is the identically designed successor to the G734III, which we have already reviewed. The only difference between the two models can be found on the inside: The G734IV has a Kaby Lake processor on-board; the G734III has a Skylake CPU. Our review reveals whether the new processor has any advantages. Rivals of the notebook are devices such as the MSI GT72VR 7RE, the HP Omen 17, the Gigabyte P57X v6, and the Acer Predator 17.

Since the G734IV and the G734III are identical in construction, we will not go into detail about the case, ports, input devices, and the speakers. Corresponding information can be found in the Nexoc G734III review.

The G734IV has a bright, high-contrast IPS display with stable viewing angles and a native resolution of 1920x1080 pixels. It is the same panel that is built into the Nexoc G734III. Nevertheless, the measured values are somewhat different, but this is normal, since two structurally identical panels never match 100%.

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 (26.7 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 27 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. » 52 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 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: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6262 (minimum: 43 - maximum: 142900) Hz was measured.

Performance

With the G734IV, Nexoc delivers a 17.3-inch gaming notebook that is based on the P670HS-G barebone made by the company Clevo. The device can be individually configured on Nexoc's website. Our review unit can be had for about 2,400 Euros (~$2547). There are also preconfigured versions available in the Nexoc shop; the currently most affordable model sports a price of around 1,600 Euros (~$1698).

Processor

While Intel's Core i7-6700HQ (Skylake) processor is used in the Nexoc G734III, the G734IV is powered by its successor: the Core i7-7700HQ (Kaby Lake). It is a quad-core processor that works at a base frequency of 2.8 GHz. The clock speed can be raised to 3.4 GHz (four cores), 3.6 GHz (two cores), or 3.8 GHz (one core) with Turbo, thus achieving 200 to 300 MHz higher clock speeds than its predecessor, which leads to somewhat better results in our CPU tests. There are hardly any architectural differences between Skylake and Kaby Lake. The CPU Turbo is maxed out, so the CPU handles single-threaded applications at 3.4 to 3.8 GHz and multithreaded applications at 3.4 GHz.

System Performance

A powerful processor and a lightning-quick NVMe SSD provide a system that works very swiftly. Our subjective impression is confirmed by the very good results in the PCMark benchmarks. Even though the Nexoc G734IV is above all a gaming notebook, it can also be used in other areas of application, such as photo editing or video editing. The overall performance cannot be increased, as Nexoc has already exhausted everything.

Storage Devices

A blazingly fast Samsung PCIe/NVMe SSD serves as the system drive. It is an M.2 model (2280) with a total capacity of 512 GB. The SSD's transfer rates are excellent. The G734IV has a second M.2 slot as well. If you wish to occupy both, you have to use SATA SSDs, which can then form a RAID-0 or RAID-1 array. The inside of the notebook additionally offers space for two 2.5-inch hard drives. One is already on board; it has a capacity of 2 TB and operates at 5400 RPM.

Graphics Card

As far as the GPU is concerned, the G734IV and the G734III are identically equipped: Both computers come with Nvidia's GeForce GTX 1070 graphics core. The GPU supports DirectX 12 and achieves speeds of up to 1886 MHz. However, this value can only be maintained for a short while. During our tests, the average speed of the GPU is at around 1700 MHz. The core is supported by 8192 MB of GDDR5 RAM. The results of the 3DMark benchmarks are at a normal level for this graphics core.

In the control center of the Nexoc notebook, you can choose between two modes: "MSHybrid" and "Separate". The first means that the built-in switchable graphics solution (Optimus) is activated. The second option activates G-Sync. Subsequently, only the dedicated graphics core operates. We performed all tests with Optimus.

Gaming Performance

All titles in our database can be played on the Nexoc G734IV, even in Full HD resolution and with high to maximum quality settings. The processing power of the built-in hardware is also more than sufficient for 4K resolution, but you would have to connect an appropriate monitor for that.

Emissions

System Noise

The automatic fan control is activated during our test. Nexoc should readjust it, as one of the three fans is always running in idle mode, resulting in permanent noise. Every now and then, the cooling system unnecessarily works at full force. If you want less noise, you have to take care of it yourself: The fan control can be manipulated in the notebook's control center. However, the laptop is always clearly audible under load. During our stress test, we measure a sound pressure level of 56 dB; in an everyday gaming situation, the noise level is between 46 and 50 dB.

Temperature

The G734IV finishes our stress test (Prime95 and FurMark run for at least an hour) differently depending on whether it is running on battery or plugged in. In the latter case, the processor works at 2.8 GHz, occasionally being slowed down to 700 MHz. The GPU's clock speed is at around 1400 MHz. In battery operation, the CPU mainly works at 1.7 GHz, while the graphics core fluctuates between 600 and 1443 MHz. The notebook does not warm up significantly during the test; only one measuring point reaches a considerably elevated temperature. The heat development is not so extreme in day-to-day use, since our stress test is an extreme scenario that does not occur in everyday use.

Energy Management

Power Consumption

We measure a maximum power consumption of 22 watts in idle mode. The G734IV is thus slightly more modest than its Skylake predecessor. The results are different under load: The power requirement of the Nexoc laptop rises up to 224 watts during our stress test, slowly pushing the 230-watt power supply to its limits. The notebook's consumption varies between 74 and 92 watts (average: 86 watts) while gaming.

Battery Life

In our realistic WLAN test, where we simulate the workload of loading web-pages with a script, the profile "Balanced" is active, the energy-saving functions are deactivated, and the display brightness is lowered to around 150 cd/m², the Nexoc G734IV achieves a runtime of 3:25 h (predecessor: 2:57 h). The notebook finishes our video test after 3:15 h (predecessor: 3:28 h). Here, we let the short film Big Buck Bunny (H.264 codec, 1920x1080 pixels) run in a loop. The wireless modules as well as the energy-saving functions are deactivated, and the display brightness is set to about 150 cd/m². In terms of runtime, the G734IV and G734III are in tight competition: Each achieves better results than the other in two cases. Both computers have the same 60 Wh battery.

In review: Nexoc G734 IV. Test model provided by Nexoc Germany.

The Nexoc G734IV can be primarily put into the category "model update". The new Kaby Lake quad-core processor has only a slight performance advantage over its Skylake predecessor. Just as the G734III, the G734IV can also run all current games smoothly in Full HD resolution with high to maximum quality settings. Activating Nvidia's G-Sync technology ensures smooth images on the 60 Hz display. The matte IPS Full HD display delights with a high degree of brightness, high contrast and stable viewing angles.

With the G734IV, Nexoc delivers a rounded gaming notebook for gamers who like to upgrade their laptop.

The notebook's heat development is within normal limits for a gaming laptop. Nexoc should improve the automatic fan control in idle mode: The fan is always on and sometimes unnecessarily speeds up, which becomes annoying after a while. Fortunately, users can fix this themselves.

A fast NVMe SSD guarantees a very speedy system. The necessary storage space is provided by an also present 2.5-inch hard drive that offers a total of 2 TB of storage. A second 2.5-inch hard drive can be installed if this is not enough. To switch the drives, the bottom case of the notebook would have to be removed.
