Lenovo's IdeaPad Miix 320 is a compact, 10-inch convertible with a removable keyboard dock, making the device versatile. Lenovo offers three different base configurations of the IdeaPad Miix 320 in its web shop. All models use Intel's Atom x5-Z8350 central processing unit with an integrated Intel HD Graphics 400 for video output. Differences are found in RAM, screen, and storage device capacity.

Our review sample is the most expensive device priced at 459 Euros (~$350). In addition to the named processor, it comes with 4 GB of DDR3 RAM and a 128 GB SSD. Also, this the only model whose 10.1-inch panel has a resolution of 1920x1200 pixels. The LTE modem is just as present as a Windows 10 Home 64-bit license. Lenovo does not offer any optional hardware configurations during the ordering process.

We selected identically configured convertibles for comparing Lenovo's IdeaPad Miix 320 in this review. An overview can be found in the following chart that also includes the comparison devices' most important technical specs.

Case and Connectivity

Lenovo's IdeaPad Miix 320 is a tablet and keyboard dock combination. The tablet turns into a small laptop that is very compact in a folded state. The weight of both components adds up to just 1049 grams (tablet: 566 grams, keyboard dock: 483 grams). Lenovo's IdeaPad Miix 320 is offered in two colors: Steel gray like our review sample, and pearly white.

The 10-inch tablet is pleasant to hold and the silver plastic cover hides fingerprints outstandingly. The stability is also good; the tablet can only be warped marginally with quite some effort and responds to these attempts with a quiet cracking noise. The keyboard dock makes an identically good impression although twisting is more difficult due to higher stability. The materials make a premium impression and convey good quality.

The tablet is connected to the keyboard dock via a magnet. Unfortunately, the tablet wobbles slightly when connected, which reduces the positive quality impression slightly. Otherwise, the hinge does a reliable job and keeps the tablet well in position.

The connectivity of Lenovo's IdeaPad Miix 320 is good and sufficient for its intended purpose. Unfortunately, the tablet does not have a full-sized USB port, which could be annoying in routine use. However, we found a USB Type-C port and a micro-HDMI port that underlines the multimedia properties on the right. Connecting the keyboard dock adds two USB 2.0 ports to the connectivity.

The Wi-Fi performance of Intel's Dual Band Wireless-AC 3165 module is below average. We measured an average of 272 MBit/s when transmitting data. The reception speed of Lenovo's IdeaPad Miix 320 is slightly better at 289 MBit/s. Our review sample carries an LTE modem by Fibocom (Fibocom L831-EAU) for mobile data connections. (The US model apparently lacks such a module).

Lenovo IdeaPad Miix 320 keyboard dock
Lenovo IdeaPad Miix 320 keyboard dock

The keyboard dock for Lenovo's IdeaPad Miix 320 is included and turns the tablet into a small, useful laptop/netbook. Unfortunately, the manufacturer does not install a subtle backlight that would help working in unfavorable light conditions.

The keys are level with the wrist rest that consequently means that the keyboard is lowered slightly into the keyboard dock. The letter keys have a pleasant size although the numbers in the first row are a bit cramped. A condition that is tolerable in routine use. It is more annoying that the enter key is relatively small. On the other hand, the keyboard convinced us with a clearly palpable pressure point and a pleasingly short drop. The keyboard easily copes with typing without producing a high noise level.

The ClickPad has a size of 9x6 centimeters and uses the space below the keyboard ideally. The surface matches to the rest of the appearance and is perfectly suitable for fast navigation thanks to the sleek texture. However, clicking noises are very audible. We found the slightly loose gliding area that clatters a bit due to a marginal play unpleasant.

The touchscreen in Lenovo's IdeaPad Miix 320 has a favorable working surface area of 10.1 inches, which is enough for simply browsing the Internet on the sofa. The screen is responsive and it is fun to work with it.

Our review sample is furnished with a 10.1-inch IPS panel with a resolution of 1920x1200 pixels. Lenovo also offers the IdeaPad Miix 320 with an IPS screen that has a resolution of just 1280x800 pixels.

Lenovo's IdeaPad Miix 320 achieved an average screen brightness of 244 cd/m² during our measurements. That places it just before Acer's Switch V that has the lowest rate in this comparison with 239 cd/m². The average screen brightness is dimmed to 210 cd/m² in battery mode. The screen's black level (0.33 cd/m²) is not convincing, either. Furthermore, we have to strongly criticize the illumination of 79%, which is far below average. However, the rivals only do a marginally better job than Lenovo's IdeaPad Miix 320 here. We were very surprised that we did not encounter clouding. The measured PWM frequency (19000 Hz) is also very high, which is favorable for the screen.

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
24 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 11 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. » 32 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
32 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 18 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. » 18 % of all devices are better.
This means that the measured response time is better than 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 19000 Hz ≤ 90 % brightness setting

The display backlight flickers at 19000 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 19000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

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 high black value that results in a low contrast ratio of 761:1 covers dark scenes with a light grayish haze. The colors look a bit pale, but this does not restrict everyday use strongly. The DeltaE 2000 rates of 5.34 and 6.04 are clearly increased in state of delivery. This indicates that the manufacturer ships the screen to the customer without prior calibration. Calibrating improves the color shifts. We have provided the corresponding ICC profile for download.

As to color space coverage, our review sample can reproduce 81% of the sRGB color space and still 51% of the AdobeRGB color space. This is a sooner mediocre outcome that will be enough for hobby photo editing.

We would not recommend using this device outdoors. The reason: the much too low screen brightness cannot defy bright outdoor conditions in sunlight. Furthermore, the very glossy surface leads to further restrictions that make use almost impossible even in the shade.

The screen in Lenovo's IdeaPad Miix 320 makes a good impression in our viewing angle test. The test image reproduction is good to very good in almost every position. The panel only has problems in the corner photos that are covered with a light grayish haze. Here, the upper two photos are affected more than the two lower photos. However, this should not lead to restrictions in routine use since this phenomenon only occurs in a very flat viewing angle.

Performance

Our review sample carries Intel's Atom x5-Z8350 processor that finds support in 4 GB of DDR3 RAM. The 128 GB flash memory is enough for the operating system and office applications. The performance of the small quad-core processor can cope with office tasks and smaller multimedia jobs. However, the LatencyMon analysis shows that the latencies are too high during high load, and thus the device is unsuitable for real-time audio playback applications.

Processor

Our review sample sports Intel's Atom x5-Z8350 processor that has four physical computing cores. The base clock of the small quad-core SoC is 1.44 GHz to 1.92 GHz (Burst). The power dissipation is just 4 watts, making the processor very suitable for passive cooling. The Cinebench test shows that the performance lags far behind Intel's Pentium N4200. However, Lenovo's IdeaPad Miix 320 cannot compete against similarly equipped devices by Telcast and Acer, either.

More benchmarks concerning Intel's Atom x5-Z8350 can be found here.

Lenovo's IdeaPad Miix 320 easily manages the Cinebench R15 loop test. The performance of Intel's Atom x5-Z8350 processor is reliably maintained completely even during prolonged load.

Despite the passive cooling unit, the casing does not get excessively hot. We measured the warmest point of 38.9°C on the rear.

Thanks to the low TDP of 4 watts that both the GPU and CPU have to share, Intel's Atom x5-Z835 processor clocks at an average of 533 MHz in the load test. We recorded 63°C as the little SoC's maximum temperature. This extreme scenario does not reflect everyday use and only shows whether the cooling design can cope with the demands.

Rerunning 3DMark 11 presented a similar outcome as a cold start.

Speakers

Speaker charakteristic
Speaker charakteristic

Two speakers are situated on the display's lower edge. Speech is well-intelligible although trebles and mids are prominent due to the compact build. Basses are muted completely and the settings in the Dolby Audio software do not change that. The maximum volume of almost 70 dB(A) distorts and overloads the playback unpleasantly. Users who want a first-rate sound experience will have to use an external player. The combined audio jack and HDMI port functioned without issues in the test.

Power Consumption

All devices, including our review sample are very frugal. Lenovo's IdeaPad Miix 320 is happy with 3 to 6.4 watts when idling. We measured a maximum load power consumption of 11 watts. Our review sample presents the worst outcome compared with devices furnished with Intel's Atom processors. Nevertheless, Lenovo's IdeaPad Miix 320 is a very frugal convertible. The power supply's maximum output power of 20 watts is sufficient.

Charging time

The non-removable battery is sufficiently sized with 33.3 Wh. Our Lenovo IdeaPad Miix 320 shut down after 7:41 hours on one charged battery. The test was based on a script that opens different websites every 30 seconds and thus simulates Internet browsing. The "Balanced" energy profile is enabled, and the screen's brightness is set to approximately 150 cd/m², which means dimming the screen by 3 levels in this case.

Verdict

Lenovo's IdeaPad Miix 320 is a 10-inch convertible. The quad-core processor and 4 GB of working memory is sufficient for its intended purpose. However, buyers should keep in mind that the 459 Euro (~$350) device is not a premium-range machine. Consequently, short waiting times will occasionally be needed. The 128 GB SSD has enough capacity, but smaller versions are also offered. We would recommend customers to take a device with 128 GB of storage.

Lenovo's IdeaPad Miix 320 makes a very high-quality impression despite its low price. Thanks to the good choice of materials, the laptop still looks impeccable even after a while of use. The keyboard dock turns the tablet into a small laptop within seconds.

The convertible has to accept criticism primarily for its screen. The screen did not convince us with its brightness of just 244 cd/m². Also, the highly reflective surface is distracting and makes outdoor use virtually impossible. The insecure connection between tablet and keyboard dock that does not correspond to the good first impression after looking closer did not appeal to us. The manufacturer should rework this point in order to satisfy the appearance's quality claim into the smallest detail.

The input devices of Lenovo's IdeaPad Miix 320 leave us with mixed feelings. The keyboard actually offers a pleasing typing comfort - but it also lacks details here as a backlight should be standard these days!?
