Dell Inspiron 13 5379 (i5-8250U, UHD 620) Convertible Review

Mike Wobker, Felicitas Krohn (translated by Alex Alderson), 02/16/2018

Old on the outside, new on the inside. Dell has updated the Inspiron 13 5379 with an Intel 8th generation Kaby Lake processor. This is the only noteworthy change though. Aesthetically, everything remains the same, including the I/O. In this review we will be clarifying what performance you should expect from the Dell Inspiron 13 5379.

Our test device comes with an Intel Core-i5 8250U, Intel UHD Graphics 620, 8GB of RAM, and a 256 GB SSD. The Inspiron 13 5379 has a 1,920 x 1,080 touch enabled display too. Dell varies its pricing not only according to hardware, but also to what version of Windows 10 is chosen. Our test device came with Windows 10 Home pre-installed, but it is worth noting that for an additional charge Windows 10 Pro is available too.

We compare the Inspiron 13 5379 with similarly equipped devices and with its predecessor that comes with an i7-6500U processor. Our comparison devices are the Acer Spin 5 and the Lenovo Miix 520-12IKB, which are also equipped with an Intel Core i5-8250U.
We have also included a Yoga 720-13IKB in our comparison as it has a processor that is available for the Inspiron 13 5379 too.

Case

Since nothing has changed aesthetically compared to its predecessor, we instead refer you to our review of the Inspiron 13 5368. Our impression of the case in 2016 still stands today. The plastic case lacks rigidity while there is still a large gap between the display and the base when using the device in tablet mode. It is also worth noting that the device is both the heaviest and the thickest convertible among our comparison devices.

Connectivity

The Inspiron 13 5379 continues the basic and somewhat dated selection of ports reported in our review of its two-year-old predecessor. While USB-C would have been a nice addition, the device does come with a full-sized SD card reader and an HDMI port.

SD card reader

SD card performance has marginally improved compared with the Inspiron 13 5368. While performance is still average, it is at least on par with laptops in its class. SD cards protrude only 1 mm from the case too. During testing our reference card, the Toshiba Exceria Pro SDXC 64 GB UHS-II, achieved an average data transfer rate of just over 28 MB/s.

Communication

In terms of Wi-Fi performance, the Inspiron 13 5379 is definitively faster than its 2016 counterpart, offering send and receive speeds of almost 635 MBit/s and 600 MBit/s respectively. The Atheros/Qualcomm QCA6174 Wi-Fi card with 2 x 2 antennas is clearly well implemented here. The device comes with Bluetooth 4.2.

Accessories

Dell offers no accessories specifically for the Inspiron 13 5379. Every device comes with one year's worth of free Dropbox storage limited to 20 GB. Unfortunately, McAfee anti-virus comes pre-installed as a trial version, the lack of which we praised the Inspiron's predecessor for in our 2016 review. No other programs come pre-installed though.

Maintenance

We refer to our review of the Dell Inspiron 13 5368 for an overview of maintenance options with the Inspiron 13 5379.

The Inspiron 13 5379 comes with a glossy IPS touch display with a 1,920 x 1,080 resolution. The panel has ten-point multi-touch and palm rejection too. Matte screens are rare in this class, with most competition manufacturers opting for glossy displays. It is worth noting that Dell does not offer alternative displays for the Inspiron 13 5379 either.

The average screen brightness is high enough for clear reading of whatever is on the screen, while reflections can be compensated for, especially when the device is being used indoors. The brightness is very uneven at the bottom of the screen, with significant backlight bleed obvious in dark rooms, although, this would be hardly noticeable in daily use.

Our test device keeps up with the average for its class. Colors look pale and blacks look slightly gray. While the black value and contrast levels are competitive, the Inspiron 13 5379 lags with respect to color reproduction. Dell has only minimally improved this compared with the Inspiron 13 5368. We detected PWM during our tests too, measured at 192 Hz when at 90 percent brightness. Display flicker at this frequency will quickly irritate most eyes.

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
33 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 13 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. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
45 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 21 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. » 69 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 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 192 Hz ≤ 90 % brightness setting

The display backlight flickers at 192 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 192 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9064 (minimum: 43 - maximum: 142900) Hz was measured.

The Inspiron 13 5379 has good viewing angles. When used in a dark room the screen can be seen from practically any angle without picture or color distortions. The same cannot be said when using the Inspiron outside. The glossy reflection inducing screen inhibits being able to read content clearly. This lack of readability even extends to using the device in the shade. The highly reflective screen makes it difficult to recognize what is on the screen. We would therefore have concerns about effectively using the Inspiron 13 5379 outside on a sunny day.

Performance

Our test device is equipped with an Intel Kaby Lake 8th generation processor. The Core i5-8250U is supported by integrated Intel UHD Graphics 620, 8 GB of RAM and a 256 GB SSD. The combination of this hardware means the Inspiron 13 5379 is capable of more demanding tasks and could even be used to play older games to a good standard.

 

Processor

Our test device comes with Intel's quad-core Core i5-8250U. Processing power is limited by the Inspiron’s running temperature. The processor can turbo clock up to 3.5 GHz at 15 W thermal design power (TDP) and has a base clock speed of 1.6 GHz to save energy and reduce heat. The i5-8250U can also use Hyperthreading to process up to eight threads simultaneously.

Cinebench R15 CPU Multi 64 Bit

The Inspiron 13 5379 achieved above average results in a single pass of Cinebench R15. It is just over ten percent ahead of its predecessor in a single pass, with the lead extending to almost fifty percent on multiple passes. Not everything is rosy though as our endurance tests show the limitations of having a 15 W quad-core CPU in a laptop case. Performance falls sharply after a short time before dropping further to an average after about fifteen minutes of testing. This throttling is not an issue exclusive to the Inspiron 13 5379 though as this behavior is consistent across our comparison devices with Core i5-8250U's onboard.

System Performance

The Inspiron 13 5379's system performance has not drastically improved over our two-year-old 5368 test devices. It is only fifty points ahead of its predecessor in the PCMark 8 Work benchmark, while the older model even marginally beats its successor in the PCMark 8 Home benchmark. Results do fall within an expected margin though, with the real advantage of 8th generation Kaby Lake chips being their energy efficiency and power per-watt. 

The Inspiron 13 5379 runs smoothly in daily use with no visible lag or overly long load times. The performance of the Core i5-8250U in other systems can be found on our CPU benchmark page.

Storage Devices

Dell has installed a slow Micron-1100 SSD in our test device, and as such, comparative performance is correspondingly poor. This performance gap is relative though, as programs still open quickly and the SSD is still faster than traditional HDD's

The relative performance of the Micron-1100 SSD can be found on our HDD / SSD benchmark page.

Graphics card

The Inspiron 13 5379 only comes with one option for graphics, that being Intel's integrated UHD Graphics 620. The available video memory and processing speed rely heavily on the RAM with which the UHD Graphics 620 is equipped; dual-channel RAM reaps huge benefits. Our test device only comes with single-channel though, which means that the GPU will not perform at the peak of its powers. This could be rectified through retrofitting dual-channel RAM.

The Inspiron 13 5379 is well behind the competition in the 3DMark benchmarks. The GPU performance gap that single and dual-channel RAM causes is clear when comparing the device to the Acer Spin 5 or the Lenovo Miix 520. While the gap is not huge, the effect that the choice of RAM has on GPU performance is striking. It is therefore worth bearing in mind that the 5379's GPU performance could be improved with a simple change of RAM. The performance of Intel's UHD Graphics 620 can be compared on our GPU benchmark page.

Gaming Performance

The Inspiron 13 5379 performs as expected when gaming. Old games, such as Bioshock Infinite, will run smoothly at medium quality. Casual games found on the Windows Store also proved no problem for our test device. Our test results further demonstrate the issue of pairing the UHD Graphics 620 with single-channel RAM. Our comparison devices equipped with dual-channel RAM achieve up to fifteen percent better FPS when gaming than the Inspiron 13 5379.

The performance of Intel's UHD Graphics 620 in other games can be compared on our games benchmark page.

Emissions

System Noise

The fan in our test device is silent in normal use. Accordingly, our microphone will only measure ambient sounds. The fan only comes on when needed and turns off as soon as the device has cooled down. The fan also adjusts its running time according to the time needed to cool the device and does not just stay on for a fixed amount of time. While the fan remains quiet at 35 dB(A), its whirring sound could be annoying for some.

Temperature

Surface temperatures always remain reasonable. When idle, the hottest area of the device measured at just under 35 °C (95 °F), with the same area reaching 60 °C (140 °F) under load. We found the hottest area to be on the rear of the device next to the middle of the display hinge. Happily, the palm rest remain pleasantly cool in both situations.

In our one stress test, the system is subjected to extreme workloads relatively quickly. The system throttles heavily until the fan starts to cool the device. Core temperatures then settle at just under 80 °C (176 °F). It is worth bearing in mind that this is an extreme stress test and not something that would normally occur. The system should not throttle due to heat from daily use.

Speakers

The Inspiron 13 5379 has a relatively balanced sound, but one which has no bass, and a low maximum volume. Our editorial staff was left with the impression that the sound tended to become tinny when listening to the device for extended periods of time. In daily use, the device could still easily be used for occasional audio playback though.

Power Management

Energy consumption

The Inspiron 13 5379's energy consumption is on par with comparable devices. When idle the maximum power consumption is under 9 W. This rises to just above 42 W under load. While this is close to the maximum wattage of the bundled 45 W power supply, there should be no issues when charging the device when it is operating under load.

Battery life

While the Inspiron 13 5379 has markedly improved battery life over its predecessor, it still is only average compared to the competition. The more energy efficient Core i5-8250U helps the 13 5379 last five and a half hours in our Wi-Fi test, an improvement of ninety minutes over the Inspiron 13 5368. On the other hand, the Lenovo Yoga 720 and the Acer Spin 5 last significantly longer than the Inspiron 13 5379.

The Inspiron 13 5379 is more of a laptop than a tablet. The Inspiron's dimensions add to this impression. Folding the display 360° creates an extremely thick tablet, the use of which is frequently disturbed by the gap between the display and the base. While our review sample looks outdated, everything is up to date internally.

"If you only use tablet mode occasionally, or you would like to use a laptop supplemented by a touch screen, then the Inspiron 13 5379 would be a good choice. Overall, a powerful and maintainable convertible with an Intel 8th generation Kaby Lake processor."

The Inspiron 13 5379 is a capable device that performs all office tasks smoothly. It is also suitable for occasional games too, but only those that are older or from the Windows Store. The ease with which the device can be maintained or repaired ensures good long-term system performance.
