MagyarLenovo Yoga 510-15IKB Notebook Review
For the original German review, see here.
With the Lenovo Yoga 51015IKB, we have an identically constructed sister model to the already-tested Yoga 510-15ISK. The difference is mainly in the brains: In the Yoga 510-15IKB, you have Intel’s new Kaby Lake processor in use, instead of last year's Skylake. The Kaby Lake processor is also to be found in rivals such as the HP Pavilion 15 x360 and the Dell Inspiron 15 5568.
Given that both Yoga 510 models are identically built, we will not go further into the casing, connectivity, input devices, display, and speakers. These details can be found in the test report of the Yoga 510-15ISK.
Connectivity
The Yoga 510-15ISK and the Yoga 510-15IKB are identically built. However, there is one minor difference: our current test machine includes a fingerprint reader. The official product photos from Lenovo only show the model without a fingerprint reader.

Display
This Yoga is equipped with the same display as the already tested sister model. However, it distinguishes itself somewhat by its specifications. But even two identically specified panels are never 100% the same. The badly built IPS panel used in this notebook offers a higher contrast and better viewing angles but unfortunately the brightness is insufficient.
A surprise: With a brightness level of 50% and under, the display exhibits Pulse Width Modulation flickering at a frequency of 50 Hz. This can give even nonsensitive people headaches and/or eye problems. The display of the Yoga 510-15ISK however, while imperfect, has no such flickering.

The display backlight flickers at 50 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % 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 17348 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Performance
With the Yoga 510-15IKB, Lenovo delivers a convertible laptop in 15.6-inch format. It offers sufficient processing power for all current application scenarios and can support gaming, albeit to a limited extent. Our test device, priced at about 800 Euros (~$847), is worth buying. Other configurations are available.
Processor
The Yoga is powered by a dual core Intel Core i5-7200U (Kaby Lake) processor. This is a power-saving CPU (15 W) and is therefore a middleweight so to speak, which should, however, completely satisfy the performance requirements of most users. The CPU runs at a minimum speed of 2.5 GHz. In Turbo Mode it can climb to 3.1 GHz (both kernels). The full processing performance is available on both AC power or when running off the battery. In our CPU tests the Kaby Lake processor achieves about 15% better than the previous generation Skylake CPU (Core i5-6200U). This is due to the higher operating speed. Skylake and Kaby Lake hardly differ in their technical details.

System Performance
A fast solid-state drive and a powerful processor ensure a smooth running system. Problems will not be encountered that often. Indeed the results from the PCMark benchmarks turned out well. An increase in system performance is hardly possible since Lenovo has already maxed out on everything.

Storage Device
The included drive is an SSD from Samsung. This 2.5-inch model offers a total capacity of 256 GB of which, about 180 GB is usable. The remaining storage space is occupied by the recovery partition and the Windows installation files. The transfer rate of the SSD proved to be quite good.

Graphics Card
The Yoga comes with a Radeon R7-M460 graphics processor from AMD. It is essentially a renamed Radeon R7-M360. After the installation of the latest graphics drivers, the M460 GPU is managed in the Windows device manager as an M360. The two GPUs are technically the same. The M460 GPU runs at a slightly higher maximum processing speed (984 MHz Vs. 980 MHz). Therefore the 3DMark results of both GPUs are very nearly the same. In addition, one can interpret the 3DMark output as evidence that the M460 GPU is a viable rival of the Nvidia GeForce 930M.

Gaming Performance
The Yoga allows computer gaming. However, one must be satisfied with HD resolution (1366x768 pixels) and low to medium playing quality settings. For performance-hungry games such as “Mafia 3” and “Deus Ex Mankind Divided”, the strain is too much. These games are not playable. While the Radeon GPU’s performance in the 3DMark benchmarks come in at the same level as Nvidia’s GeForce 930M, in actual gaming experience it falls behind the Nvidia GPU.

Emissions and Energy
System Noise
While idling, the Yoga did not generate too much noise. The fan remained sometimes still and it achieved complete silence. However, when running with even a pretty small load, the fan starts running. During the stress tests the fan speed increased. We measured a sound pressure level of 38.6 dB(A) - quite a good value.

Temperature
Our stress test (Prime95 and FurMark ran for at least one hour) ran on the Yoga in both AC power and battery-powered scenarios. The processor worked in battery mode at 400 MHz, and an AC power mode at 2.5 GHz. The GPU always ran at 600 MHz. In subsequent runs of the tests the GPU (on AC power) occasionally throttled at 300 MHz. The laptop did not heat up excessively. At a few measuring locations the temperature exceeded 40°C (~104 °F).
(±) The maximum temperature on the upper side is 42.9 °C / 109 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(±) The bottom heats up to a maximum of 44.6 °C / 112 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 25 °C / 77 F, compared to the device average of 31.3 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.6 °C / 83.5 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (+0.2 °C / 0.3 F).

Energy Consumption
While idling, we measured a maximum energy requirement of 8.4 watts, as it should be. During the stress tests the value increased to 46 W. Given the base processing speed of the GPU and the fact that the CPU did not use Turbo mode, this is noticeable. Otherwise the value would be somewhat higher. In everyday gaming the performance requirement moved to about 37 watts +/- 10 watts. The rated requirement on AC power is 65 watts.

Battery Runtime
Our practical WLAN tests simulated web browsing. The Balanced Power Profile was active, the display brightness was set to about 150 cd/m², and energy saving functionality was activated. The Yoga provided a running time of 5:20h. This is nearly the same as its sister model.

Pros
Cons
Verdict
Lenovo’s 15.6-inch convertible comes with a cutting-edge Kaby Lake processor, which offers sufficient computing performance for all application types. The Radeon GPU allows at least limited computer gaming. The justification for the dedicated GPU is dubious since it is not particularly strong and may be merely a gimmick. The integrated GPU would have performed just as well. Furthermore, the rival Nvidia GPU clearly offers more gaming performance at the same price, in this case 800 Euros (~$847).
As a rule, the laptop runs in everyday life quietly and does not become excessively hot. The solid-state drive guarantees a fast running system. You can set up a model with a greater capacity drive, but this requires swapping out the drive yourself by removing the bottom panel as there is no maintenance hatch. The laptop's chiclet keyboard is sufficient. The battery life proved adequate. The built-in Full HD IPS display pleased us with its high contrast, decent viewing angles and a normal color representation. Unfortunately the display’s brightness is too low.
Lenovo offers in the Yoga 510-15IKB a solid 15.6-inch 2-in-1 convertible, that is not without weaknesses.
