Lenovo Legion Y740-17IRHg with a GeForce RTX 2080 Max-Q in Review

Attractive gaming laptop! Gamers rejoice! The Lenovo Legion Y740-17 offers great gaming performance and various RGB elements to complement the design. In this review, we will try to find out whether there are any drawbacks by looking at numerous measurements and benchmarks.
Sebastian Bade, 👁 Sebastian Jentsch, Andrea Grüblinger (translated by Marius S.),

Lenovo's Legion series consists of gaming laptops. Thus, its devices need to deliver a decent performance. Furthermore, the Legion family devices are visually distinct due to RGB highlights.

Prospective buyers can expect to pay around 2700 Euros (~$2965) for our test configuration. In return, the device features the Nvidia GeForce RTX 2080 Max-Q, which is the highest-end GPU option. Cheaper models are equipped with either an Nvidia GeForce RTX 2070 Max-Q or an Nvidia GeForce RTX 2060 Max-Q. Although there are more powerful processor options available, our configuration only sports an Intel Core i7-9750. The Intel Core i9-9880H, which is both slightly more expensive and slightly faster, would be the next step. The latter even has 8 cores.

The competition includes similarly equipped devices. These laptops are listed in the following table.

Case & Features - Good, but Not Perfect

The Lenovo Legion Y740-17 stands out visually as a gaming laptop. The typical design elements of the Legion series are emphasized by RGB lighting. The choice of materials is good as well, since the manufacturer uses a lot of aluminum. As a result, the base unit and the lid are quite rigid, although the keyboard center can be observed to yield slightly under pressure. However, the extent of this remains within reason. Various design elements such as the fan grilles on the base unit and the display bezels are made of plastic. The display can be opened to a maximum angle of a generous 180 °. Even then, the two hinges reliably prevent teetering. Meanwhile, since the base is heavy enough, the display can be opened one-handed. At 3 kg (~6.5 lb), the Lenovo Legion Y740-17 is significantly heavier than its competitors. For a 17-inch device, it is still not very heavy. The port selection of the laptop is solid. Most ports can be found on the back. However, there is also one USB port on each side. We still are not too happy about the Mini DisplayPort, since a normal DisplayPort would have made more sense. We also regret the absence of a card reader.

The Lenovo Legion Y740-17 is equipped with a Killer Wireless AC 1550i module. It delivers a good and stable performance in our test. However, our test device falls short of the fast Intel Wireless AC 9560, which can for example be found on the Asus ROG Zephyrus. Lastly, the Legion Y740 also comes with an RJ45 port.

Input Devices

Lenovo has fitted the Legion Y740 with a 6-row chiclet keyboard with an RGB backlight. It can be controlled for example, with Corsair's iCue software, which can be used to display certain effects. The keys are comfortably sized. However, the numpad requires some getting used to, since the key layout is unusual. The keys offer shallow travel and a somewhat dull feedback with a distinct actuation point.

The integrated touchpad should only be used as a mouse substitute when it is absolutely necessary. While the surface is smooth and responsive all the way to the edges and corners, the surface area relative to the laptop's size is quite small. The two buttons on the bottom offer fairly deep travel. Furthermore, their clicks are rather quiet. That being said, the actuation point is still very distinct, which makes for a satisfying feedback.

Lenovo has fitted our Legion Y740 with a matte Dolby Vision panel with 144 Hz and Nvidia G-Sync. The 17-inch IPS display has a native resolution of 1920x1080 for a theoretical pixel density of 127 PPI.

According to our measurements, the installed panel does not quite reach its advertised maximum brightness. On average, we observed only 281 cd/m². However, it even exceeds the specified 300 cd/m² with 310 cd/m² in the center. The contrast ratio of 1000:1, matches our expectations for an IPS panel. Since some competing laptops offer more in terms of brightness or lower black values, they tend to be able to achieve better results.

Since the Lenovo Legion Y740-17 does not use PWM to control the display's brightness, users will not have to worry about eyestrain or similar issues. However, our device suffers from some amount of backlight bleeding. In dark scenes, it is quite noticeable around the edges.

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
11 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 5 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. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
16 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise

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 636 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (38.7 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9599 (minimum: 5 - maximum: 142900) Hz was measured.

Even though almost all competitors achieve better results, display is good in all respects. Ex-factory, DeltaE-2000 grayscale and color values are only slightly higher than their sRGB reference points. At 93% and 60%, respectively, the sRGB and AdobeRGB color space coverage cannot match competitors, either. However, these values are still sufficient for semi-professional photo editing.

The outdoor usability of the Legion Y740-17 is limited. If outdoor use is unavoidable, users should remain in the shade. In our viewing angle test, the result we observed matches our expectations for a normal IPS panel. Only the four corner images appear to be covered by a faint veil. However, this has not proven to be distracting during normal use.

Performance - Sufficient Performance for Current Games

A modern gaming laptop demands the use of fast and recent hardware. Lenovo appears to have had the same idea and has equipped the laptop with an Intel Core i7-9750H and an Nvidia GeForce RTX 2080 Max-Q. With 16 GB, the RAM is sufficient as well and the storage capacity should last users a while. Thankfully, the individual components also work well together when it comes to running software. In our test, LatencyMon did not detect any problematic latencies.

Processor

The laptop relies on an Intel Core i7-9750H with 6 physical Hyper-Threading cores for computational tasks. The CPU is able to process up to 12 threads simultaneously. In our tests, the Intel Core i7-9750H performs well. The performance of the SoC in our test sample is on a similar level as its competition. Only the Alienware m17 R2 with its faster Intel Core i9-9980HK surpasses the other devices in our comparison by a significant margin.

In our stress test, during which we run the Cinebench R15 multi-thread benchmark test in a loop, the Lenovo Legion Y740-17 achieves a relatively good result. The maximum boost clock speed is no longer available by the second loop, which leads to an overall performance deficit. Subsequently, the performance level stabilizes, making the Legion Y740 about as fast on average as the Razer Blade Pro 17 in its first loop.

More comparisons and benchmarks can be found in our CPU comparison table.

Gaming Performance

When it comes to gaming, the Legion Y740's performance is average. Here, the Razer Blade Pro 17 is the laptop to beat. That being said, even modern games can be played smoothly at the native resolution and maximum quality settings. During our stress test, which consists of running "The Witcher 3" on the ultra preset, the performance drops slightly. However, users will not have to worry about unplayable frame rates.

System Noise

Gaming laptops and noise under load often go hand in hand. The Lenovo Legion Y740 does not exactly spare users either, although 40.8 dB(A) also is not an excessively high value. That being said, the fans are very noticeable while gaming. Fortunately, the frequency of the fans is not too high.

Temperature

When only looking at the surface temperatures, Lenovo appears to have done a good job. Here, the surfaces are far from reaching 50 °C (122 °F) and only a few spots cross the 40 °C (104 °F) mark. The processor's core temperatures do not look quite as good. When exclusively stressing the CPU, its core temperature does not reach critical values. However, as soon as the GPU comes into play, the SoC's temperatures can reach up to 95 °C (203 °F). Meanwhile, we observed a maximum core temperature of 76 °C (~169 °F) for the Nvidia GeForce RTX 2080 Max-Q.

Speakers

In terms of audio, there are two stereo speakers, which are complemented by a subwoofer for lower frequencies. The sound is balanced overall and at least offers some amount of bass. For an ideal audio experience however, we still recommend using a headset. The latter can be connected to the laptop via the 3.5 mm jack or USB.

In review: Lenovo Legion Y740-17IRHg, courtesy of

The Lenovo Legion Y740-17 is a well-equipped and fairly reasonably priced gaming notebook. Comparable devices with similar specifications often cost more than 3000 Euros (~$3300). Instead, the Legion Y740-17 can be purchased from various online shops for around 2700 Euros (~$2965). For the price, buyers receive a visually appealing laptop with subtle, customizable RGB lighting. However, the installed components should be the main focus. The Intel Core i7-9750H is a safe choice. The six-core SoC delivers solid performance. An Nvidia GeForce RTX 2080 Max-Q was selected as the graphics card and combined with the SoC, even the latest titles run smoothly. As for the screen, it has a native Full HD resolution and a 144-Hz refresh rate as well as G-Sync shows that Lenovo has designed this device primarily with gamers in mind. Similarly, it is a good choice for light photo editing.

The Lenovo Legion Y740-17 is a solid gaming laptop that is definitely worth considering.

Overall, the Lenovo Legion Y740-17 is a good gaming machine with only minor weaknesses. For example, the battery life is slightly below average and the touchpad could have been slightly bigger. In terms of raw performance, the Lenovo Legion Y740-17 has showcased its ability to keep up with the competition in our comparison.

The port selection is nothing out of the ordinary. Still, a full size DisplayPort would have been good to see, since it would have made using special cables or adapters unnecessary.

From an early age I was interested in technology and was then able to learn the desired profession of "IT systems electronics engineer". Subsequently, my 12-year military service began, during which I learned a lot and kept my knowledge constantly up to date with the latest technology. Since I would like to share this with you, Notebookcheck offers a very good possibility to offer this to the masses. Furthermore, I am very much involved with water cooling and network security.
