Lenovo Legion Y740-17ICH (i7-8750H, RTX 2080 Max-Q) Laptop Review

Cheapest laptop with RTX 2080 graphics. A mid-range laptop equipped with a high-end GPU. The Lenovo Legion Y740 is just as powerful as some of the popular heavy hitters in the enthusiast gaming notebook market even if it doesn't quite look or feel the part.

When we reviewed the 17.3-inch Legion Y730-17ICH late last year, we were baffled as to why Lenovo was not offering any GPU options higher than the GTX 1050 Ti. Both Core temperature and fan noise were relatively low especially for a gaming laptop to suggest that the chassis was capable of housing faster and more demanding GPUs. Fast forward to CES 2019 and now we know why Lenovo was holding back on additional GTX GPUs—it was preparing for GeForce RTX Legion SKUs all along.

Called the Legion Y740, the system sports RTX graphics compared to the GTX-powered Legion Y730 series. The Y740 is otherwise visually identical to the Legion Y730 and so both models carry the same keyboard, connectivity options, and physical features. We recommend checking out our existing review on the Legion Y730-17ICH for more details on the chassis since many of our comments still apply here for the Legion Y740.

Note that the Legion Y740 series comes in 15.6-inch (Y740-15ICH) and 17.3-inch (Y740-17ICH) SKUs just like on the Legion Y730 series. We will be checking out the 15.6-inch version at a later date.

The unit we have today sports a 17.3-inch 144 Hz IPS display, Core i7-8750H CPU, and a GeForce RTX 2080 Max-Q GPU for around $2400 USD. This is surprisingly inexpensive considering the specifications as many competing RTX 2080 laptops like the Acer Predator Triton 500, MSI GS75, Asus ROG GL704, or Razer Blade 15 can retail for $3000 or more. Did Lenovo cut any corners on its RTX offering?

Case

The chassis remains identical to the Legion Y730-17ICH including all the customizeable rear LED lights. Surfaces feel thinner and more flexible than many competing 17-inch gaming laptops including the Asus ROG GL704, Razer Blade Pro, MSI GE75, and Alienware m17. Additionally, the system is lacking the narrow bezels of the 15.6-inch Legion Y740-15ICH and its lid tends to teeter more when adjusting the angle. Thus, chassis rigidity is the weakest aspect of the Y740-17ICH when compared to the competition.

The Lenovo laptop has the notable trait of being relatively thin but with a large footprint. For example, the system is over 30 mm longer and 10 mm wider than the competing Asus ROG GL704 and yet it is 3 mm thinner. The elongated rear and thick bezel design are responsible for the large chassis.

Interestingly, Lenovo is listing the Y740 a hair thicker than the Y730 (23 mm vs. 21.95 mm). This could just be a result from the conversion between inches and SI.

Connectivity

Port positioning will be unusual to many gamers. Whereas other gaming laptops typically have most or all of their ports along the left and right edges, the Legion Y740 has most of its ports along the rear instead. There are certainly pros and cons to this approach that gamers will either love or hate. In our opinion, having to reach around the rear of the laptop whenever we need to access commonly used ports can become bothersome.

The system still lacks an integrated SD reader. Thankfully, both Thunderbolt 3 and mini-DisplayPort are present.

Accessories

There are no extras in the box for a barebones unboxing experience.

Maintenance

Serviceability is identical to last year's Legion Y730. We can notice no obvious changes to the motherboard layout between the two generations aside from the additional cooling over the chipset adjacent to the covered RAM slots.

Warranty

The standard one-year limited warranty applies. Lenovo offers a wide range of optional extensions including accidental damage protection and onsite support for up to three years.

Input Devices

Keyboard and Touchpad

The keyboard and trackpad are identical to the Y730 and so all our existing comments still apply here. In summary, we find key feedback to be too weak and travel too short especially for a gaming laptop. The keyboards of the Gigabyte Aero 15, MSI GS65, and Alienware 17 feel stronger and firmer. On the bright side, clatter is quiet, the directional keys are large, and the numpad is an uncommon feature for its category.

The trackpad is relatively small but accurate nonetheless with no cursor jumping. Responsiveness is very smooth because of the native 144 Hz refresh rate.

Display

Lenovo has upgraded the 60 Hz 1080p IPS panel on the Legion Y730 to the 144 Hz 1080p IPS panel we have here. Both contrast ratio and response times have improved significantly while other characteristics like brightness and color coverage remain largely the same. The high quality AU Optronics B173HAN03.2 panel is common on enthusiast gaming laptops including the Asus ROG G703GI. Note that Lenovo is not offering any 4K UHD or touchscreen options for its Y740 series as of this writing.

We can notice some minor graininess on the matte panel that would otherwise be absent on a glossy panel. It's not severe enough to be distracting, but it's present nonetheless. Heavy backlight bleeding is present along the edges of our test unit that's even worse than what we saw on the Legion Y730. We're hopeful that this is not a widespread issue.

Further measurements with an X-Rite colorimeter reveal inaccurate colors and an overly cool color temperature out of the box. Our calibration directly addresses these shortcomings for a noticeably better picture. Average grayscale DeltaE in particular drops dramatically from 6.8 to 1.9. We recommend an end-user calibration if possible to get the most out of the display.

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
12.8 ms ... rise ↗ and fall ↘ combined↗ 7.6 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 0.8 (minimum) to 240 (maximum) ms. » 15 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.7 ms).

This means that the measured response time is better than the average of all tested devices (39.3 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: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18082 (minimum: 5 - maximum: 2500000) Hz was measured.

The 300-nit backlight is average for a 17-inch gaming laptop and so outdoor visibility is unimpressive. The heavier Alienware 17 R5 has a 33 percent display if outdoor visibility is priority. Even so, these large gaming laptops are not designed to be away from AC outlets for very long.

Viewing angles are excellent as expected from an IPS panel. Viewing from extreme and unrealistic angles will impact both contrast and brightness slightly.

Performance

The Legion Y740 can be configured with an RTX 2060, 2070 Max-Q, or 2080 Max-Q in contrast to the GTX options on the Y730 series. Lenovo says future SKUs are ready to support the next generation of Core ix CPUs following Coffee Lake-H whenever Intel is ready to announce it.

Interestingly, the Core i7-8750H CPU comes standard on all current SKUs with no Core i5-8300H option in sight.

Another important difference between the Y730 and Y740 is the lack of Optimus graphics switching on the latter. Lenovo decided to include G-Sync this time instead which we find to be more appropriate for the target hardcore gamer.

 

Processor

CineBench R15
CineBench R15

CineBench R15 Multi-Thread results are 11 percent higher than the average Core i7-8750H in our database taken from 70 other laptops. This suggests excellent Turbo Boost performance when under high load much like what we discovered on the Legion Y730. CPU performance is even better than the stock Core i9-8950HK found on the XPS 15 9570.

We can measure performance sustainability by running CineBench R15 in a loop as shown below. The initial high score of 1233 points drops to 1139 points by the second loop to represent a performance dip of only 7.6 percent. Results are consistently faster than the same CPU as found on the Gigabyte Aero 15X and Asus Zephyrus S GX701GX.

See our dedicated page on the Core i7-8750H for more technical information and benchmark comparisons.

System Performance

PCMark ranks our Legion Y740 just a few percentage points ahead of last year's Y730 with the exception of the Digital Content Creation test where the Y740 scores significantly higher. This particular benchmark favors PCs with high performance GPUs like our RTX 2080 Max-Q. We experienced no software or hardware issues during our time with the test unit.

Storage Devices

Two internal storage bays are available (1x M.2 2280 + 1x 2.5-inch SATA III). Our specific test unit is equipped with a 256 GB Samsung PM981 NVMe SSD and a secondary 1 TB Seagate ST1000LM049. The SSD in particular is a huge upgrade from the Toshiba in our Legion Y730.

AS SSD returns an unusually slow sequential read rate of 1152.78 MB/s whereas the Lenovo Ideapad 730S equipped with the exact same SSD returns a sequential read rate of 2323.41 MB/s. Meanwhile, CrystalDiskMark 5.5 shows a read rate of 2089 MB/s. We're unsure why this is, but we otherwise didn't experience any drive issues during our time with the test unit.

Competing 17-inch gaming laptops like the Alienware 15 or Asus ROG G703 have more internal storage options than the Legion Y740.

See our table of SSDs and HDDs for more benchmark comparisons.

GPU Performance

3DMark benchmarks rank our RTX 2080 Max-Q about 9 percent behind the last generation GTX 1080 and just 5 to 10 percent ahead of the RTX 2070 Max-Q. Due to the wide TDP range of the mobile RTX 2080 family, however, some laptops with the same RTX 2080 Max-Q GPU may perform even faster than our Lenovo. The Asus Zephyrus S GX701GX, for example, scores about 15 to 20 percent higher than our Lenovo.

Performance is slower than a standard mobile RTX 2080 by about 30 percent. In comparison, the GTX 1080 Max-Q is just 10 percent behind the standard mobile GTX 1080. It's a bit disappointing to see an even wider performance deficit for this latest generation of Max-Q GPUs.

Gaming Performance

Real-world gaming performance is most similar to the the mobile RTX 2070. It's possible to reach a stable 144 FPS at 1080p to take advantage of the native 144 Hz refresh rate with most settings turned to Medium.

Running Witcher 3 results in stable frame rates throughout with no interrupting dips or performance throttling.

See our dedicated page on the GeForce RTX 2080 Max-Q for more gaming benchmarks and our review on mobile Turing for more technical information.

Emissions

System Noise

We were anticipating the Legion Y740 to run louder than the Legion Y730-17ICH since the RTX 2080 Max-Q is much more powerful than the GTX 1050 Ti. To our surprise, however, fan noise is almost identical. Fan noise is in the low-to-mid 40 dB(A) range when running Witcher 3 compared to over 50 dB(A) on enthusiast gaming laptops like the Alienware 17 or MSI GE75.

The fans are almost always active even during low processing loads, but they thankfully remain relatively quiet with no sudden or acute changes to RPM. System noise will never be truly silent if a secondary HDD is installed much like what we have here.

We can notice no coil whine on our test unit.

Surface temperatures were relatively cool on the last generation Legion Y730 and this remains true for the Legion Y740. When gaming, the keyboard hotspot is only 33 C to 36 C compared to 40 C on the Asus ROG G703GX equipped with the full-fledged RTX 2080. The wider chassis design and superfluous ventilation along the rear, bottom, and sides make this Lenovo laptop run surprisingly cool considering the hardware inside.

The bottom rear of the notebook can become as warm as 43 C and so it's important to not impede the fans or airflow when gaming.

Stress Test

We stress the system with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed operating at 3.9 GHz for the first few seconds until reaching a core temperature of 82 C. Thereafter, the processor stabilizes at 3.4 to 3.5 GHz to maintain a cooler core temperature of 70 C. Since the base clock rate of the Core i7-8750H is 2.2 GHz, the Y740 is able to sustain relatively high levels of Turbo Boost that coincide with our CineBench test results above.

When running Witcher 3, the CPU and GPU stabilize at 71 C and 64 C, respectively, which are warmer than on last year's Legion Y730 but otherwise still relatively cool for a gaming laptop. In comparison, the same CPU and GPU in the Acer Triton 500 stabilize at warmer core temperatures of about 84 C and 78 C, respectively, when running the same game.

Running on batteries will impact CPU and GPU performance even when set to the High Performance and Prefer Maximum Performance power profiles. 3DMark 11 Physics and Graphics scores when running on batteries are only at at 15893 and 8863 points, respectively, compared to 25765 and 12623 points when on mains.

Energy Management

Power Consumption

The system demands anywhere between 20 W to 29 W when idling on desktop compared to just 6 W to 12 W on last year's Legion Y730. This significantly impacts battery life as our next section below will show. Results are not unlike other enthusiast gaming notebooks equipped with GTX 1070/1080 or RTX 2070/2080 level graphics.

When gaming, the Y740 draws a constant 152 W to be 33 percent more demanding than the Legion Y730 under similar conditions. More impressively, the system is 39 percent more power efficient than the Razer Blade Pro with GTX 1080 graphics while performing up to 13 percent faster in the DX12 Time Spy benchmark. The performance-per-Watt from the RTX 2080 Max-Q is quite impressive when compared to the RTX 2070 as well.

Running Prime95 will demand a constant 80 W without any sharp dips since Turbo Boost performance is relatively stable. We're able to record a maximum draw of 165 W from the large (~20 x 10 x 2.7 cm) 230 W AC adapter. This adapter is noticeably larger than the 135 W adapter that shipped with the Legion Y730.

Battery Life

Runtimes are significantly shorter when compared to last year's Legion Y730. When running the same WLAN stress test, the Y740 lasts for just over 3 hours or less than half the runtime of the Y730. We attribute this to both the 144 Hz panel and RTX 2080 Max-Q graphics which indubitably demand more power than the 60 Hz panel and GTX 1050 Ti GPU on last year's model. The lack of Optimus graphics switching is another hard hit on battery life.

When compared to other enthusiast gaming laptops like the Asus ROG GL704GW or Razer Blade Pro, however, WLAN runtime is where we expect it to be.

Charging from empty to full capacity takes about 1.5 hours.

Verdict

In review: Lenovo Legion Y740-17ICH. Test model provided by Lenovo US
In review: Lenovo Legion Y740-17ICH. Test model provided by Lenovo US

Most OEMs normally reserve the high-end GeForce 80-class GPUs for their enthusiast flagship models. This used to be the Legion Y900 family for Lenovo, but the manufacturer has since put that series on hold leaving the mid-range Legion Y700 series as the highest-end offering. The result is a mid-range gaming laptop with a high-end GeForce GPU at much more affordable prices than competing "super" gaming laptops like the Alienware m17, Asus ROG G703, MSI GT75, or Acer Triton 700. The Lenovo laptop offers the same gaming performance as these enthusiast alternatives for hundreds of dollars less largely because its chassis design is simpler and less eccentric.

CPU performance is faster than the average Core i7-8750H due to excellent Turbo Boost sustainability. Both core temperatures and fan noise are lower than expected as well considering the thin form factor and high performance.

Because the Legion Y740 carries a mid-range chassis, however, first impressions are not as strong as the aforementioned high-end alternatives. The Lenovo is more prone to flexing and teetering than the more rigid (and pricier) MSI GT75 or Asus ROG G703. Our specific unit also suffers from moderate-heavy backlight bleeding and inaccurate colors. Its keyboard keys are softer and generally poorer for gaming, too. Gamers won't lose out on performance, but the weaker chassis and keys will put a dent on the overall gaming experience.

The mid-range Legion Y740 retails for much less than a competing enthusiast 17.3-inch gaming laptop while sporting the same high-end CPU and GPU. It has excellent bang-for-the-buck in terms of performance so long as you're ok with its modest design and more flexible chassis.
