The Yoga 730-15IKB is a 15.6-inch convertible that comes with a dedicated graphics card, which means that it can be used to play video games. The Yoga 730-15IKB is a successor to the previously reviewed Yoga 720-15IKB. The biggest difference between the two devices lies inside: Lenovo replaced the standard mobile processor (TDP: 45 watts) found in the Yoga 720 with a ULV model (TDP: 15 watts). The competing devices include: The Asus ZenBook Flip 15 UX561UD, the Acer Spin 5 SP515-51GN-80A3 and the HP Spectre x360 15-ch011nr.

Because the Yoga 720-15IKB and the Yoga 730-15IKB are identically built, we shall skip the sections that deal with the input devices and the speakers, and we are also not going to provide detailed descriptions of the case and the connectivity options. You can find all the appropriate information in our review of the Yoga 720-15IKB.

Case & Connectivity – Differences between the two Yoga laptops

  • At first glance, both laptops look almost identical. However, there are a few differences between the two convertibles. The Yoga 730-15IKB is a little thinner than its predecessor, the Yoga 720-15IKB. There are also a few small differences in terms of the size, width and the length. There are no differences when it comes to the build quality, rigidity and the choice of materials.

  • The standard mobile processor found in the Yoga 720-15IKB (TDP: 45 watts; Core i7-7700HQ) was replaced with a ULV model (TDP: 15 watts; Core i7-8550U).

  • The Yoga 730-15IKB offers all the ports that the Yoga 720-15IKB did. However, the Yoga 730 comes with an additional HDMI port, which means that it can output two video signals at the same time, one via Thunderbolt 3 and the other via HDMI.

  • The battery of the Yoga 730 has a significantly smaller capacity than that of the Yoga 720 (51.5 Wh vs. 72 Wh).

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 961 Hz ≤ 90 % brightness setting

The display backlight flickers at 961 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 961 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8933 (minimum: 43 - maximum: 142900) Hz was measured.

Right out of the box, the display offers a fairly good color reproduction. With a DeltaE 2000 color deviation of 3.9, it misses the mark slightly (DeltaE less than 3). The display does not suffer from a bluish cast. The screen cannot fully cover either the Adobe RGB color space (39%) or the sRGB color space (90%).

By means of our color profile, the color reproduction can be improved. However, before downloading it, you should make sure that your laptop has the same display model (manufacturer + model number) as our review device, because otherwise our color profile can result in worse color reproduction. Displays from different manufacturers can often be found within notebooks from the same model range.

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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 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. » 40 % 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
34 ms ... rise ↗ and fall ↘ combined↗ 16 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. » 23 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 ms).

The Yoga 730 comes with an IPS panel with very good viewing angles. Therefore, the screen content can be read from any position. Outdoors, the laptop can be used only when the sun is not shining too brightly. Moreover, strong reflections make reading screen content more difficult.

Processor

The Yoga 730 is powered by a Core i7-8550U (Kaby Lake Refresh) CPU from Intel. The Intel CPU has four cores and a base clock rate of 1.8 GHz. The Core i7-8550U is a ULV processor that provides enough performance for all modern usage scenarios. Thanks to Intel’s Turbo Boost technology, the CPU’s clock rate can be boosted up to 4 GHz.

In the multi-core Cinebench benchmarks, the CPU runs for a few seconds at 3.7 to 4 GHz. After that the processor operates at 3 to 3.1 GHz. In the single-core benchmarks, the clock rate fluctuates between 3.4 and 4 GHz. When running on battery power, things look different. The CPU runs constantly at 1.8 GHz in the multi-core benchmarks and at 3.7 to 4 GHz in the single-core benchmarks.

We check if the Turbo boost can be used over an extended period of time by running the Cinebench multi-core benchmark in a continuous loop for 30 minutes. The results sink after the first benchmark run. After that, they stay on the same level. The Turbo boost is used. However, it does not run at full speed.

All in all, the Core i7 performs very well. In the single-core benchmarks, the Yoga 730 does as well as other competing devices such as the Asus ZenBook Flip 15 UX561UD and the Acer Spin 5 SP515-51GN. However, the Yoga 730 performs better in the multi-core benchmarks. In the Cinebench loop, the CPU of the Yoga 730 runs at higher clock rates than the competing devices.

In the single-core benchmarks, the Yoga 730 outperforms its predecessor. Apparently, the CPU in the predecessor model cannot operate at full speed. In terms of multi-core performance, both devices are on the same level.

System Performance

The Core-i7 processor and a fast NVMe SSD create a very responsive system. We did not encounter any problems. The Yoga 730 offers more than enough computing power for such usage scenarios as office work and Internet browsing. The Yoga 730 can run most modern video games, thanks to a dedicated GPU. Our review device achieves very good results in the PCMark benchmarks. An increase in overall performance is not possible.

The Yoga 730 achieves worse results in the PCMark 8 benchmarks than the similarly equipped Acer Spin 5 SP515-51GN, because the display of the Yoga 730 (3840x2160) has a much higher resolution than that of the Spin 5 (1920x1080).

Storage Devices

An NVMe SSD from SK Hynix serves as the system drive. It comes in the M.2-2280 form-factor and has a capacity of 512 GB. Right out of the box, only 415 GB is available to the user. The rest of the storage space is occupied by the Windows installation files and the recovery partition. The transfer rates are in good order. NVMe SSDs achieve much faster transfer speeds than SATA III SSDs, because they are connected via PCI Express 3.0 x4.

Graphics Card

The Yoga 730 comes with the GeForce GTX 1050. The GTX 1050 is a dedicated, upper mid-range GPU, which is based on Nvidia’s current Pascal architecture. It supports DirectX 12 and has a maximum core clock of up to 1493 MHz. The GPU comes with 4 GB of GDDR5 VRAM. The results in the 3DMark benchmarks are on the normal level for this kind of GPU. However, the results fall slightly behind those of other GTX 1050-based notebooks. This can be attributed to the thinness of the laptop. As a rule, thicker notebooks offer better cooling solutions than thin and light devices like the Yoga 730. As a result of this, the GPUs can run at higher clock speeds.

Besides the GTX 1050, the convertible also features Intel’s UHD Graphics 620. The Yoga 730 also supports Nvidia’s Optimus technology, which allows automatic switching between a dedicated GPU and an integrated graphics adapter.

Gaming Performance

The GPU of the Yoga 730-15IKB can run all video games that we tested at decent frame rates. In most cases, the games can be run at Full HD resolution and on the medium to high settings. A few titles from 2017/2018 require the resolution and detail settings to be lowered in order to achieve playable frame rates. The frame rates are on a normal level for this kind of GPU. However, other GTX 1050-based laptops can achieve slightly higher frame rates. It is possible that the GTX 1050 in the Yoga 730 runs at lower clock speeds than in other devices.

The full resolution of the 4K display cannot be used. The GPU is not fit for such high resolutions. Only older titles such as Team Fortress 2 can achieve playable frame rates at 4K resolution. Those who want to be able to play video games in 4K should get a different notebook with at least a GTX 1060, or better yet a GTX 1070.

Emissions – Quiet Yoga notebook

System Noise

As a rule, the fan stands still when idle. This leads to silent operation. Under load, the fan starts to spin up. We measured a sound pressure level of 37.5 dB(A) under both medium and full loads. The CPU operates at lower clock speeds under full load. All in all, the Yoga 730 produces a normal amount of noise for a convertible with a dedicated GPU.

Temperature

The Yoga 730 during the stress test
The Yoga 730 during the stress test

The Yoga 730 gets different results in our stress test (Prime95 and FurMark running for at least one hour) when it is plugged in and when it is running on battery power. When connected to power, the CPU and the GPU run at high clock rates. During the stress test, the CPU frequency falls down to 400 MHz. The core clock of the GPU stabilizes at about 1500 MHz. When running on battery power, the clock rate of the CPU fluctuates between 400 MHz and 1.8 GHz. The graphics card runs at anywhere between 400 MHz and 1.3 GHz.

The laptop does not become excessively hot. During the stress test, the 40-°C (104 °F) mark is exceeded at four measurement points. The stress test represents an extreme case scenario, which is highly unlikely to occur in real life. We use this test to see how the system fares under full load.

Energy Management – Yoga notebook with a downgraded battery

Energy Consumption

There are no abnormalities in terms of energy consumption to report. When idle, we measured a maximum power draw of 10.7 watts. During the stress test (Prime95 and FurMark running for at least one hour), the energy consumption peaked at 94.6 watts. We registered this result at the beginning of the stress test. After 90 seconds, the power consumption fell down to 80 watts. The rated output of the AC adapter amounts to 90 watts. The ULV processor makes itself noticeable under load. Here, the 15-watt Core i7-8550U consumes significantly less power than the 45-watt Core i7-7700HQ found in the Yoga 720-15IKB.

Battery Life

In our practically oriented Wi-Fi test, the Yoga 730 achieves a runtime of 6 h 10 m. This test simulates loads that are consistent with surfing the web. The “balanced” power plan is selected, the energy-saving functions are turned off and the display brightness is set to 150 cd/m². The convertible achieves a runtime of 5 h 24 m in our video test. During this test, we play the short film Big Buck Bunny (H.264, 1920x1080) in a continuous loop. The communications modules are disabled, the energy-saving functions are switched on and the display brightness is set to 150 cd/m².

That the Yoga 730 has shorter battery life than its predecessor is not surprising. Our current review device comes with a 51.5-Wh battery, whereas the predecessor had a 72-Wh battery. The 4K display is also to blame for shorter battery life. The previously reviewed Yoga 720 came with a Full HD display. In terms of battery life, the Full HD models of the Yoga 730 should be on the same level as the Full HD models of the Yoga 720.

Update 10/22/2018: The battery life of the FHD model are significantly longer than that of the 4K variant. During idle, the battery life almost doubles, at that even though it has the same battery capacity. This jump seems unusually high to us, so we are still evaluating it. Currently the WiFi test is still running, and we will add the result here.

There are no visible changes between the Yoga 730-15IKB and its predecessor, the Yoga 720-15IKB. The only thing that has changed is the CPU: The Yoga 730 comes with a 15-watt ULV processor instead of a 45-watt CPU.

Our review device features a Core i7-8550U. This is a quad-core CPU that offers more than enough performance for all modern tasks. Positive: The CPU can utilize its Turbo Boost functionality over an extended period of time. Thanks to a dedicated GPU, the Yoga 730 can run most modern games. 

Lenovo’s 15.6-incher represents a combination of an entry-level gaming notebook and a convertible.

Lenovo used a ULV CPU as an excuse to cut the battery capacity. The battery of the Yoga 730 is 30% smaller than that of the Yoga 720. In combination with a 4K screen, the Yoga 730 achieves mediocre battery life at best. However, competitors such as the Acer Spin 5 SP515-51GN and the Asus ZenBook Flip 15 UX561UD do not perform any better in this regard.

An NVMe SSD creates a very responsive system. The SSD can be replaced. However, you will have to open up the case to do this. The keyboard left a good impression. It is suitable for those who do a lot of typing. Positive: The keyboard features a backlight. The IPS 4K touchscreen delights with its great viewing angles, good color reproduction, solid contrast ratio and acceptable brightness. It can be operated either with the fingers or with the included stylus.

With the Yoga 730, things are easier for those who use external monitors: Unlike the Yoga 720, the Yoga 730 has a Thunderbolt 3 port and also an HDMI output.

Update 10/22/2018: Not only is the alternative Full-HD variant of the Yoga 730-15 up to 600 Euros (~$688) more affordable than the 4K version, but it is also (slightly) brighter and has a higher contrast. In addition, there is a better Adobe RGB coverage due to the FHD panel. Even though the ColorChecker value turned out slightly worse in the FHD model, if you use our calibration profile (or calibrate it yourself with a photo spectrometer), the value drops below 3.0. 

In addition to the display aspect, there is also a longer battery life, particularly during idle (6 hours more). Our WiFi test is still running. 

Thus there are many reasons to look for the more affordable FHD model.

This model will also be available with Intel's brand-new Whiskey-Lake processors. This will probably happen soon, since Lenovo already lists these models on its website.
