Lenovo Legion Y740-17IRH Review: Gaming bolide gets high marks for its great power delivery and low heat development

Well-rounded gamer. Lenovo's gaming notebook displays all current games smoothly on its matte 17.3-inch screen (144 Hz, G-Sync, FHD, IPS) and also offers great connectivity: a combination of SSD + HDD, 16 GB of RAM (dual-channel mode) & a Thunderbolt 3 port. The iGPU is disabled ex-works but can be activated by the end user. This has a positive impact on battery life.

Lenovo's 17.3-inch gaming notebook is not unknown to us. We already reviewed its sibling, the Legion Y740-17ICH, which has the same build. Today's test unit is equipped with a Core i7-9750H processor and a GeForce RTX 2060 GPU. Some of its competitors are the Asus Strix Hero III G731GV, the MSI GL75 9SEK, the Schenker XMG Core 17, the Dell G7 17 7790 and the HP Pavilion Gaming 17.

As the two Legion Y740 models have the same build, we will not go into details on the case, connectivity, input devices and speakers in this review. Please refer to our review of the Legion Y740-17ICH for information on these aspects.

Display - 144-Hz IPS with G-Sync

The Legion's 17.3-inch display has a native resolution of 1920x1080 pixels. While the display offers a good contrast ratio (1044:1), its brightness is a little too low (260.6 cd/m²). Good brightness levels start from around 300 cd/m². Fortunately, the display does not show any PWM flickering.

The 144-Hz panel in our test unit supports Nvidia's G-Sync technology, which dynamically matches the refresh rates of the display and the GPU. This should ensure an even smoother image - particularly while gaming.

* ... smaller is better

The display of the Legion already has good color reproduction ex-works. Our DeltaE 2000 measurements show a color deviation of 3.18, which is very close to the ideal value of below 3. Calibrating the display further improves color reproduction and results in a color deviation of 0.9 and more balanced grayscales. The color spaces AdobeRGB and sRGB are not covered entirely. We measured coverage of 61% of the AdobeRGB color space and 96% of the sRGB color space.

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
11.2 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 5.2 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 0.1 (minimum) to 240 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
14.8 ms ... rise ↗ and fall ↘ combined↗ 7.6 ms rise
↘ 7.2 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 0.2 (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 (33.9 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

The Lenovo notebook is equipped with an IPS panel with stable viewing angles. This means that the screen can be read from any position. It's also possible to read the screen outdoors, provided the sun is not shining too bright.

Testing Conditions

The preinstalled Lenovo Vantage software enables users to switch between various thermal modes, influencing fan use and power delivery. We ran our tests in the "balanced" mode. The other available modes are "quiet" and "performance". 

The UHD Graphics 630 GPU, which is integrated in the processor, is disabled at delivery. This means that the notebook does not work with Nvidia's graphics-switching technology Optimus. You can, however, activate the iGPU (and thereby Optimus) via the Lenovo Vantage software. This has a positive impact on the battery life of the notebook.

Processor

The notebook is powered by the six-core processor Core i7-9750H (Coffee Lake Refresh). The CPU clocks at a base rate of 2.6 GHz. The clock rate can be increased to 4 GHz (six cores), 4.1 GHz (five cores), 4.2 GHz (four cores), 4.3 GHz (three cores), 4.4 GHz (two cores) or 4.5 GHz (one core) via the Turbo Boost. 

The processor works at a clock rate of 3.8 - 4 GHz during our Cinebench R15 multithread test and at 4 - 4.5 GHz during the single-thread test. The clock rate drops to 2.6 - 4 GHz (multithread) and 4 - 4.3 GHz (single-thread) when running on battery.

We try to find out whether the CPU can continue using its turbo over a long period of time when connected to the socket by running the Cinebench R15 test in a loop for at least 30 minutes. The results drop slightly from the first to the seventh round but then stabilize and remain fairly stable for the remainder of the test. This means that the CPU continues using the turbo.

Activating the thermal mode "performance" within the Lenovo Vantage software does not improve the results. However, the trajectory of CB15 results is somewhat smoother.

Storage Devices

The primary hard drive is an NVMe SSD (M.2 2240) from Western Digital with a capacity of 128 GB. Around 86 GB of this is available at delivery. The device offers good transfer rates, although it cannot keep up with its top-of-the-range competitors. Our test unit is equipped with an additional 2.5-inch hard drive (1 TB 7200 rpm) in order to provide the necessary storage space for a gaming notebook.

Graphics

The Legion is equipped with a GeForce RTX 2060 - a current top-range GPU. This Turing model supports DirectX 12 and works with a base clock rate of 960 MHz. This clock rate can be increased to up to 1200 MHz via the turbo. The GPU can clock even faster if the chip remains below a certain temperature and/or energy limit. For example, we registered a maximum clock rate of 1784 MHz, although the device did not manage to keep this up for very long. The Witcher 3 test is completed at an average clock rate of 1414 MHz. The GPU has access to the fast GDDR6 graphics memory (6144 GB). The 3DMark results are average for this GPU.

Gaming Performance

The included hardware can display all titles in our database smoothly. The games can always be played at Full HD resolution and high to maximum settings. The GPU can also manage resolutions above Full HD, albeit at lower settings (and you would have to connect a suitable monitor for this).

In order to find out whether the refresh rate remains constant over a long period of time, we ran the game The Witcher 3 for around 60 minutes at Full HD resolution and maximum quality settings. The character in the game was not moved during this entire period. The refresh rates remained relatively consistent throughout the test and were always high enough for satisfactory gaming.

Emissions - The Legion Y740 only heats up moderately

System Noise

The Legion hardly makes any noise while idling. The fans run at low speed and occasionally stand completely still, in which case the device is silent (provided the 2.5-inch hard drive isn't being accessed). The fans turn up under load and the Lenovo notebook reached an average of 46 dB(A) during our The Witcher 3 test.

Temperature

The Legion reaches different results in our stress test (Prime95 and FurMark running for at least 1 hour) depending on whether it's running on mains or on battery. On mains, the processor clocks at between 2.6 and 2.7 GHz. The GPU, meanwhile, clocks at 1000 MHz. On battery, the clock rates drop to 800 MHz (CPU) and 600 - 1700 MHz (GPU). The stress test represents an extreme scenario that will not occur as such in everyday use. We use this test to find out whether the system remains stable under maximum load.

The Lenovo notebook only heats up moderately. We measured maximum temperatures in the mid 40 °Cs during the stress test. Similar temperatures were measured during The Witcher 3 test (with the game running for one hour in Full HD resolution and maximum quality settings). The results are all fine during everyday use.

Energy Management - Activating Optimus improves the battery life

Power Consumption

The Y740-17IRHg does not have any particular anomalies when it comes to power consumption. We measured a maximum consumption of 26 watts while idling. Activating the integrated GPU would reduce the consumption in this scenario. The power consumption increased to up to 168 watts during our stress test but remained lower while gaming. We measured an average consumption of 139 watts during our The Witcher 3 test. The rated output of the AC adaptor is 230 watts.

Battery Life

The Legion managed a runtime of 4:16 h (iGPU disabled) or 6:11 h (iGPU activated) during our realistic Wi-Fi test. In this test, we simulate browsing the web via a script with the energy profile set to "balanced" and the display brightness set to around 150 cd/m². Our video test lasts 4:20 h on the 17.3-inch gamer. This involves running the short film Big Buck Bunny (H.264, 1920x1080 pixels) in a loop with the energy profile set to "power saving", the radio module deactivated and the display brightness set to around 150 cd/m².

Verdict

The Lenovo Legion Y740-17IRHg (81UJ001TGE). Test unit provided by notebooksbilliger.de

Lenovo has created a 17.3-inch gaming notebook that manages to display all current games smoothly on its matte Full HD display thanks to a Core i7-9750H processor and a GeForce RTX 2060 GPU. Games can be played at high to maximum settings. Another great point: The device only reaches moderate temperatures.

An NVMe SSD ensures a speedy system. On top of the SSD, the device is equipped with a 1-TB hard drive. Both storage devices can be exchanged by the user, although this requires removing the bottom of the base unit.

The Legion Y740-17IRHg gave us a good overall impression and does not seem to have any serious weaknesses. 

The 144-Hz IPS display offers short response times, stable viewing angles, a good contrast ratio and great color display. In addition, the device supports G-Sync technology. The maximum brightness of the display is relatively low - we would have expected higher luminosity from a device in this price range.

The included keyboard (with RGB backlighting) has proven to be suitable for everyday use. The battery life is not particularly impressive, however - although this can be changed. By activating the integrated GPU, users can improve the battery life, increasing the Wi-Fi runtime from 4:16 h to 6:11 h.
