Lenovo Legion Y740 Laptop Review: Only a small CPU upgrade

Sebastian Bade (translated by Alex Alderson), 10/01/2019

The second coming. The Lenovo Legion Y740 returns to our offices, but this time with a small performance upgrade over the version that we originally tested. The 15-inch gaming laptop fared well last time during our tests, so we are intrigued to see the effect that the upgrade from an 8th to a 9th generation Intel Core processor has. Read on to find out what effect this has, or whether it is a superficial upgrade.

Lenovo only offered the Legion Y740-15ICHg with 8th generation Intel Core processors, but it has since upgraded the Y740 to the Coffee Lake Refresh (CL-R) generation. CL-R processors offer higher boost clocks than their predecessors, so we thought it would be pertinent to see what benefits the Core i7-9750H powered Y740 had over its Core i7-8750H powered predecessor. Incidentally, our new test device has a much brighter display than the one that Lenovo included in our first review unit.

We shall, of course, compare our new review unit against its predecessor. The Y740 will also go up against the HP Omen X 2S, and Acer Predator Triton 500 as they have comparable hardware.

Display - G-Sync, Dolby Vision and 144 Hz

Lenovo equips our review unit with a 15.6-inch IPS panel that it claims can reach up to 500 cd/m². The 144 Hz panel is NVIDIA G-Sync, Dolby Vision and HDR400 certified too. Lenovo only sells 1080p options though, so you will need an external monitor if you want to game in UHD or QHD.

According to our X-Rite i1Pro 2, our review unit manages an average maximum luminosity of 431 cd/m², meaning that it falls short of Lenovo's claims. The brightest point of the display only hits 477 cd/m² too, so it seems no part can reach the advertised threshold of 500 cd/m². However, on closer inspection Lenovo only claims that the display can reach up to 500 cd/m², but does not advertise it is a 500 cd/m² panel. Regardless, the panel exceeds the level to reach HDR400 certification, and it is brighter than all the displays in our comparison devices.

The IPS panel has a comparatively low black level too, which yields an equally impressive contrast ratio. Other conventional IPS panels cannot compete in this regard, but the one in our review unit does have comparatively slow response times. We did not notice any streaking during our gaming tests, though. The display does not rely on the headache and eyestrain inducing pulse-width modulation (PWM) to regulate its brightness either, and it only suffers from minor backlight bleeding.

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
10 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 4 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. » 9 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
19 ms ... rise ↗ and fall ↘ combined↗ 9 ms rise
↘ 10 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 0.9 (minimum) to 636 (maximum) ms. » 12 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (39.6 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 9266 (minimum: 43 - maximum: 142900) Hz was measured.

The display reproduces colours richly, thanks to its high contrast ratio, while its low black value makes blacks looks intense. Some black areas look more grey in parts of the display that suffer from backlight bleeding, though. However, only OLED panels reproduce colours more vibrantly than the display in our review unit can.

Lenovo also does an excellent job of factory calibrating the display. Our photo spectrometer and CalMAN analysis software determine that the panel only deviates slightly from the sRGB colour space upon delivery, although our previous Legion Y740 test device and the Predator Triton 500 perform slightly better here. Additional calibration reduced these deviations, but we were unable to eradicate the slight blue tint that affects the display. We have linked the calibrated ICC profile in the box above our comparison table should you wish to use it.

Our review unit covers 91% of the sRGB colour space and 60% of AdobeRGB, which is accurate enough for hobbyist level colour work. While these scores put the Y740 on par with its competitors, they are not high enough for colour critical work such as professional photo and video editing.

The Y740 gets bright enough to use outdoors, even on a sunny day, while its matte finish diffuses reflections nicely. The IPS panel has stable viewing angles too, although we noticed some grey hazes in the corners of the display, which spoils things slightly. Nonetheless, this should not affect readability in daily use.

Performance - Fast, but not fast enough

Our review unit may come with a theoretically faster CPU than its predecessor, but this does not necessarily ring true in all scenarios. Lenovo continues to equip the Y740 with a GeForce RTX 2070 Max-Q though, along with identical volumes of RAM and storage. The 16 GB of dual-channel DDR4 RAM should be enough for most memory-intensive applications too.

We should also point out that LatencyMon reports much higher DPC latencies with our current review unit than its predecessor. We did not notice any issues during our tests though, and hopefully future driver updates should address this.

Processor

The Core i7-9750H succeeds the Core i7-8750H, with the former offering higher base and boost clock speeds than the latter. The Core i7-9750H clocks between 2.6 GHz and 4.5 GHz, although it can only reach 4.5 GHz on two cores. Its peak boost clock drops to 4.0 GHz on all cores, which is 100 MHz higher than the equivalent of the Core i7-8750H.

Correspondingly, our review unit generally scores around 6% more in single-core synthetic benchmarks than its predecessor. Surprisingly, the opposite is the case in multicore benchmarks, where the Core i7-9750H falls 4% behind the Core i7-9750H. Our review unit performs above the class average, but it hits its thermal limits faster than its Core i7-8750H powered predecessor does.

Please see our CPU comparison page for more information on the Core i7-9750H and how it compares against other processors.

We also ran Cinebench R15 Multi 64Bit benchmark in a loop to determine how well our review unit performed under sustained load. Unsurprisingly, the Y740 throttled below the performance of its predecessor, but it remained well above our Core i7-9750H powered competitors.

System Performance

While Lenovo has equipped our current review unit with a slower SSD than the one it included in our previous Y740 test device, the two score almost identically in PCMark. Little separates our comparison devices in system performance benchmarks, with all scoring above the class average.

Subjectively, our review unit feels fast. We noticed no system problems or unnecessary waiting times during our tests, with apps and the OS loading quickly.

Storage Devices

The Y740 has M.2-2280 and 2.5-inch drive bays, which Lenovo has occupied with a 128 GB M.2-2280 SSD and a 1 TB 2.5-inch HDD. The former is a Western Digital drive, on which Lenovo pre-installs Windows 10. While the drive performed well in daily use, it fell well short of the drives in our comparison devices in AS SSD and CrystalDiskMark.

While the 1 TB HDD is well-sized to store a games library on, we would recommend replacing it with an SSD considering how cheap they have now become. Alternatively, you could remove the HDD and swap the 128 GB SSD for a larger capacity and faster drive. Nonetheless, the HDD is fast enough for loading complex modern games.

Please see our HDD/SSD comparison page for more information.

Graphics Card

The GeForce RTX 2070 Max-Q is a more efficient version of the regular GeForce RTX 2070, which NVIDIA has designed for compact laptops. The GeForce RTX 2070 Max-Q has lower clock speeds and a reduced thermal design power (TDP) compared to the regular GeForce RTX 2070, but they both have 8 GB of GDDR6 VRAM.

Most synthetic GPU benchmarks put the Core i7-9750H and its predecessor on equal footing, with our current review unit only able to outperform the Core i7-8750H powered Y740 by 6% in 3DMark Time Spy. However, the HP Omen X 2S crushes our test device here, despite them having the same CPU and GPU.

Please see our GPU comparison page for more information on the GeForce RTX 2070 Max-Q and how it compares against other GPUs.

Gaming Performance

Our current review unit can achieve slightly better framerates than its predecessor, with the slightly higher clock speed of the Core i7-9750H seemingly having a positive effect. We recorded 5% higher framerates in "The Witcher 3" on the Ultra preset at 1080p, which we suspect few people will notice. The equally well-equipped HP Omen X 2S achieves 15% more FPS than our review unit though, underlining that the Y740 cannot make best use of its CPU and GPU.

Please see our GPU games page for more gaming benchmarks.
