Convertible / 2-in-1 Kaby Lake Tablet Ultrabook

For the original German review, see here.

Little time had passed since we reviewed the Yoga 710-14ISK - yet Lenovo came up with an updated model. The new Yoga 710-14ISB comes with a Kaby Lake (7th generation) processor instead of the Skylake (6th generation) CPU. However, that's about all of the new features. The Intel Core i5-7200U is still supported by 8 GB of DDR4 RAM, while the operating system as well as all the other applications are stored on the 256 GB M.2 SSD. Our test model is not equipped with a dedicated GPU and all the graphics are handled by the integrated Intel HD Graphics 620 instead. Our silver SKU currently retails for 899 Euros (USD950, AUD1300, GBP760), and a more powerful model is 200 Euros (USD210, AUD290, GBP170) more expensive. This faster specced Yoga 710 is equipped with a slightly superior Intel Core i7-7500U CPU as well as a dedicated GPU (Nvidia GeForce 940MX).

Other than the previous Lenovo Yoga 710-14ISK, we see the HP Spectre x360 13 as a rival for the Lenovo Yoga 710-14IKB. To make comparisons of the performance without a dedicated GPU, we also use the Lenovo Miix 510 Pro as well as the Acer Aspire Switch 12 Alpha for the article.

Display Response Times

ℹ
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↗ 7 ms rise
↘ 26 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (22.3 ms).
   ↔    Response Time 50% Grey to 80% Grey
53 ms ... rise ↗ and fall ↘ combined↗ 17 ms rise
↘ 36 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (35.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 50 Hz ≤ 10 % brightness setting

The display backlight flickers at 50 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 50 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19035 (minimum: 5 - maximum: 3846000) Hz was measured.

Performance

The performance of the Yoga 710-14IKB is actually decent for a convertible. Looking at the GPU performance, the integrated Intel HD Graphics 620 is faster than the Intel HD Graphics 520, but our test model does not stand a chance against the Yoga 710-14ISK with its dedicated GPU in 3D applications. If you primarily use the system for web browsing and office tasks, the Yoga will be more than sufficient. This is also the case for 8 GB of DDR4 RAM clocked at 2133 MHz, but similar to the previous model the Yoga 710-14IKB only has one slot, so the memory is only running in a single-channel configuration. Due to the lack of an empty slot, it is not possible to expand the memory. This means the integrated Intel HD Graphics 620 of the Intel Core i5-7200U cannot utilize its full potential.

If you need significantly more 3D performance, you should get an SKU with the dedicated Nvidia GeForce 940MX which is also equipped with a faster CPU (Intel Core i7-7500U).

Processor

The Core i5-7200U is soldered.
The Core i5-7200U is soldered.

Intel's Core i5-7200U is meant to replace the older i5-6200U. The soldered Kaby Lake CPU has two physical cores and can execute up to four threads simultaneously thanks to the Hyper-Threading technology. Like the 6200U, the i5-7200U is a frugal ULV processor with a TDP of just 15 Watts. The base clock is now 2.5 GHz, not 2.3 GHz, and thanks to the Turbo the chip can reach up to 3.1 GHz.

Cinebench R15 determines performance gains of 11 percent for the Yoga 710-14IKB as compared to the 710-14ISK in the Multi test. However, the Single-Core result is only 3 percent better. The overall CPU performance of our test model is excellent and even the HP Spectre x360 with an allegedly faster Core i7-7500U CPU is beaten in the Cinebench R15 Multi benchmark.

M.2-2280 SSD
M.2-2280 SSD

Lenovo uses a Samsung SSD for the system drive. It is an M.2-2280 drive and the manufacturer lists sequential read and write transfer rates of 540 MB/s and 520 MB/s, respectively. We checked the performance of the SSD with the tool AS SSD and got the following results: 508 MB/s (read) and 478 MB/s (write), so a bit short of the claimed values. In practice, the SSD was reliable and we did not notice any performance issues. The Yoga 710-14IKB unfortunately only has one M.2 slot. This means you will have to replace the existing SSD if you need more storage space.

GPU Performance

Our test model is unfortunately not equipped with a dedicated graphics card so the calculations are handled by the integrated Intel HD Graphics 620. It was introduced with the Kaby Lake generation and should be somewhat faster than the HD Graphics 520 used in Skylake processors. The new generation can now also decode H.265/HEVC Main 10 with a color depth of 10 bit which reduces CPU load when playing high definition videos and provides more headroom for other tasks. The performance of the Intel HD Graphics 620 depends a lot on the CPU model and the memory configuration. 3DMark Fire Strike clearly shows that despite the improvements this integrated graphics adapter can not keep up with a dedicated GPU.

Gaming Performance

The fact that our test model is only equipped with the Intel HD Graphics 620 does obviously limit the gaming capabilities. Even the older titles can only be played with the Low preset in combination with the HD resolution. If you need more graphics performance, you should have a look at the Lenovo Yoga 710-14IKB with the Nvidia GeForce 940MX.

Noise characteristics

The noise development of our test model is moderate. The fan is usually not running after you turn the system on and only starts spinning when Windows is started. Our test model has one heat pipe with a small fan, which reaches up to 37 dB(A) under load. Because of the dedicated GPU, the Yoga 710-14ISK is a bit louder. The previous model is also equipped with two heat pipes to dissipate the additional heat from the graphics card. You can also get the Kaby Lake model with this GPU solution, and the system noise should be pretty similar to the previous model.

Temperature

3DMark 11 after stress test
3DMark 11 after stress test

The cooling concept of the Yoga 14IKB is sufficient, which is confirmed by our measurements. The chassis stays conveniently cool while idling and reaches an average temperature of 27°C (81°F). Under maximum load, the surfaces stay well below 40°C (104°F) with the hottest point at the center on the top of the base unit at 36.4°C (97°F). Compared to the previous model, the values are much lower thanks to the lack of the dedicated GPU. Our stress test with Prime95 results in a maximum CPU temperature of 81°C (178°F) and the Intel Core i5-7200U runs at a steady 2.9 GHz. FurMark stresses the graphics card, which results in 77°C (171°F) while the Intel HD Graphics 620 maintains an average clock of 990 MHz. We repeated 3DMark 11 right after the stress test and the result of 1497 points did not differ from a cold run. This means there are no performance problems even under high workloads.

Speakers

Speaker measurements
Speaker measurements

Similar to the previous model the two small speakers are once again provided by JBL. The sound comes from small grilles at the bottom of the base unit. Those grilles can quickly be covered on soft surfaces or when you use the device on your lap, which will affect the sound quality. We recommend using an external sound system for better sound quality.

We cannot understand why Lenovo would locate the microphones directly above the fan exhausts. Skype is no problem as long as the fan is deactivated, but otherwise, your call partner will notice an annoying murmur. Lenovo's engineers should consider changing the mic's position, because right now you need an external microphone for comfortable calling.

The convertible is pretty frugal in our consumption measurements at just 7 Watts (on average) while idling. Maximum load will pull 30 Watts from the socket, and the Lenovo Yoga 710-14IKB is the best device within the comparison group. The compact power adapter with a nominal output of 45 Watts is sufficient and still has headroom to charge the Yoga 710-14IKB under load.

After the Yoga 710-14ISK put up pretty good runtime figures, we expect similar results from the successor. The Kaby Lake Yoga is once again equipped with a 53 Wh lithium-ion battery, but thanks to the lack of the dedicated GPU, we get much better runtimes in the WLAN and H.264 test. One battery charge should easily last a full business day. It takes about 2.5 hours to recharge the convertible. The HP Spectre x360 is the only longer lasting device than the Yoga 710-14IKB within our comparison group, the only reason for that being that it possesses a bigger battery capacity.

In review: Lenovo Yoga 710-14IKB. Test model courtesy of Campuspoint.

The Lenovo Yoga 710-14IKB is just a small model update. The enduring convertible is now equipped with a Kaby Lake processor, which is 10-15 percent faster at the same power consumption. Our test model is equipped with an Intel Core i5-7200U processor as well as 8 GB of DDR4 RAM and a 256 GB SSD. Especially the battery runtimes and the low consumption figures of the Yoga 710-14IKB are convincing.

Lenovo's Kaby Lake update for the 710-14IKB still comes with the appealing chassis design of the previous model. The performance of the new model is a bit better due to the new CPU. Thanks to the good battery runtimes, the Lenovo is an enduring and reliable travel companion.

Since the manufacturer did not change the design compared to the previous model, we can still notice the same issues. The microphones are located directly above the fan exhaust, which is very annoying during video calls since the other person will hear a constant murmur. All in all, the convertible leaves a sophisticated impression. We like the choice of materials, and the performance is sufficient for most everyday tasks.
