For the original German review, see here.

The Nexoc B519 is a 15-inch office notebook. It can be configured individually and is based on the barebone chassis N350DW from the manufacturer Clevo. The office orientation is supported by the matte FHD panel, the docking port, the fingerprint scanner, TPM 2.0 and the optional SmartCard reader. In this article, we want to have a look at the processor in particular, because you do not get the usual frugal mobile processor, but a desktop i5-6600T CPU from Intel's current Skylake generation. We had not tested this processor until now.

But what are the advantages of the desktop processor and how does it compare against its mobile siblings? Almost all the direct rivals for the 15-inch office notebook are equipped with frugal ULV processors by now, one example would be the Lenovo ThinkPad E560 with the mobile Core i7. The faster processors with a higher TDP are usually reserved for multimedia notebooks or workstations like the Dell XPS 15 with the comparable i5-6300HQ as well as the Dell Inspiron 15 with the popular Core i7-6700HQ.

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↗ 7 ms rise
↘ 21 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
56 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 38 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. » 89 % of all devices are better.
This means that the measured response time is worse than 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 detected 2083 Hz70 % brightness setting

The display backlight flickers at 2083 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 70 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2083 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5069 (minimum: 43 - maximum: 142900) Hz was measured.

Performance

Processor

The Intel Core i5-6600T is a quad-core processor (Skylake) with a nominal clock of 2.7 GHz, which can be raised up to 3.5 GHz via Turbo Boost. It is a desktop chip with a TDP of 35 watts, which - contrary to the mobile ULV processors - does not support Hyperthreading.

The mobile ULV i7 benefits from its high Turbo Boost when you just stress one core and only falls behind the desktop i5 by 8% in Cinebench R15, while the 45-watt i7-6700HQ is 8% faster. Our i5 is sometimes considerably slower than its mobile counterparts are when you stress more cores, because it does not support Hyperthreading. Only the ULV i7 is 24% slower in CB R15 Multi. The nominally slightly slower i5-6300HQ (no Hyperthreading either) is on par and sometimes even a bit faster (+10% CB R15 Multi), but also consumes more power in return due to its TDP of 45 watts.

The differences in the benchmarks are therefore not that big, but the desktop processor has an advantage in the stress test. The clock is between 2.7-3.3 GHz when we only stress the processor (Prime95) and it will stabilize at 2.7 GHz when we also stress the graphics card (FurMark). You can therefore benefit from steady performance without throttling when you often use CPU-demanding applications. The ULV chips in particular are often limited by the low TDP in this scenario.

In Review: Nexoc B519 (N350DW). Test model courtesy of Nexoc Germany

An office notebook with a powerful desktop processor, is it worth it? The tested Intel Core i5-6600T leaves a good first impression. The performance is steady, even in the stress test, which can be an advantage when you use very CPU-demanding applications. The majority of office notebooks are equipped with frugal ULV chips nowadays, and the performance is often not much worse. They do have significant advantages in terms of power consumption in return and enable thinner cases, so they are often the better choice for office tasks.

The i5-6600T is an interesting option when you often use very CPU-demanding applications. Otherwise, the ULV chips offer the better overall package in respect to performance and emissions.

The Nexoc B519 performs well in many sections, starting with the very good FHD IPS display, the high system performance and the good maintainability. The office orientation is pretty serious as well, because the Clevo N350DW chassis is equipped with a decent keyboard, TPM 2.0, a fingerprint scanner, a docking port and an optional SmartCard reader. The touchpad buttons with their spongy pressure point are a problem though, because you never know if they triggered or not. The biggest issue, however, are the emissions, because both the temperature and the noise development are too high considering the chassis dimensions and the performance.

I grew up with computers and modern consumer electronics. I am interested in the technology since I had my first computer, a Commodore C64, and started building my own PCs after that. My focus here at Notebookcheck is the business segment including mobile workstations, but I also like to test new mobile devices. It is always a great experience to review and compare new products. My free time is filled with a lot of sports, in the summer mainly on my bike.
