We just provided you with a detailed comparison between the Legion Y520 and the Aspire VX 15 which are too great budget gaming solutions. But the Legion Y520 has let’s call it a bigger brother – the Legion Y720.
Lenovo Y720 is mostly the same in terms of specs as the Y520 but with a few major upgrades. First of all, it is equipped with a more powerful GTX 1060 GPU which brings it out of the budget end of the market. The Y720 also has a much more premium build quality.
Today we want to see how the more affordable Y520 performs next to the Y720 and see if it is really worth spending the extra money.
Design and construction
As for design, both notebooks are fairly similar which isn’t anything surprising keeping in mind that there are from the same series. The Lenovo Y520 has a more simple look than the Y720 which has a bright-red Y-series logo on the lid and more aggressively looking exhaust vents. Also, Y720’s hinge is quite different – when you open the device there is a gap between the screen and the body which grows wider as you progress to the edge of the device. On the other hand, the Y520 keeps things ordinary. It’s all up to personal opinion which would you like the best.
Moving on to construction, we start to feel the difference in the price range. The budget-oriented Y520 is built entirely out of plastic which imitates carbon fiber and has a matte black finish which gives the device a good grip. The plastic feels rigid and is easy to clean and is just what we expect from a notebook from this price range. Now when it comes to the Y720, we are pleased to see a rock-solid brushed aluminum plate. It definitely gives the notebook that more premium feel we are looking for. The aluminum plate is way more rigid than any plastic that’s for sure but it’s also a fingerprint magnet.
On the sides of both notebooks, you will find all the necessary ports including HDMI, RJ-45, SD card reader and a 3.5 mm combo audio jack. However, there is one tiny at first glance but important difference in the USB ports configuration. The Y520 features two USB 3.0 ports, one USB 2.0 and one USB Type-C port. On the other hand, the Y720 swaps the USB 2.0 port for another USB 3.0 port and the single USB Type-C port supports Thunderbolt 3 for high-speed data transfer and connecting external GPUs.
The display is where the Y720 falls short. Both the Y520 and Y720 use the same panel manufactured by LG carrying a model number of LP156WF6-SPK3. Further in the comparison, you will understand why we say that the Y720 falls short. The panel was decent for a budget device but it is not suitable for a more premium one. The IPS (AH-IPS) screen is 15.6 inches in diagonal and has a resolution of 1920 x 1080p (Full HD) which translates to a pixel density of 142 ppi. The pixel pitch is 0.18 x 0.18 mm.
And as of color reproduction – this is where we are most concerned. Just 52% of the sRGB gamut for the Y520 wasn’t particularly a good value but we could overlook this drawback considering the price. But being able to display only half of the colors used in HDTV and the web for the Y720 is a major setback. The screen also uses PWM to control the brightness level (read more here). Fortunately, the frequency used is very high which reduces the harmful impact – 20.7 kHz for the Y520 and even higher at 21.6 kHz for the Y720. Our custom-tailored profiles (you can check them out over here) you can further decrease the unwanted effect.
Specs wise both models are nearly identical. They are running on the Intel Core i7-7700HQ from the latest 7th generation Kaby Lake. The CPU features four physical and four logical cores (Hyper-Threading) with a base clock speed of 2.80 GHz. The chip’s consumption is 45 Watts, and its maximum operating temperature is 100 degrees Celsius.

The graphics card is where they differ. The budget Y520 is equipped with the GeForce GTX 1050 Ti while the Y720 features the more powerful GTX 1060 GPU. The GTX 1050 Ti is enough to run every modern game but the GTX 1060 will provide you with the power to display some beautiful graphics.

The Y720 has a bigger 60 Wh battery to support the more demanding GTX 1060 graphics card. However, during web browsing or video playback, the GPU is not heavily used and the bigger battery results in better battery life. The Y720 lasted for 350 minutes (5 hours and 50 minutes) of web browsing while the Y520 – 256 minutes (4 hours and 16 minutes). The difference in the video playback test is smaller – Y720 scored 284 minutes (4 hours and 44 minutes) compared to the 240 minutes (4 hours) of the Y520. And of course, we have to note the battery endurance when gaming because these notebooks are branded as gaming devices. With the Y720 you will get just half an hour more of gaming than the Y520 – 113 minutes (1 hour and 53 minutes) vs 86 minutes (1 hour and 26 minutes).
Performance is where the Y720 is the undoubtful winner. The GeForce GTX 1060 GPU is much more powerful than the GTX 1050 Ti. While the GTX 1050 Ti can run any game and get you decent 60 fps on medium settings, the GTX 1060 can give you up to 50% higher fps in some games at medium and even provide a playable 30 fps at maxed settings. Though it seems that neither of them is enough to push Tom Clancy’s The Division.

In the initial 30 minutes in which we conduct out CPU stress test the Y520 almost immediately dropped its frequency to 3.4 GHz which is still well in the Turbo Boost range, however, it kept temperatures high at around 90 °C. On the other hand, the Y720 ran at 3.4 GHz for about 10 minutes but then it dropped down to 2.7 GHz but ran very cool at around 60 °C. Our best guess is that there are some still unfixed issues with this engineering sample.
Things get a bit out of hand when we add the GPU stress test for the Y520. The CPU started throttling down to 800 MHz every few seconds and then returning back to 3.0 GHz and the already high temperature further increased to 100 °C which is its maximum operating temperature. A 100% CPU+GPU load is not something you would do in real life but still, you can expect some thermal throttling from the notebook. Lenovo has apparently removed this issues from the Y720 because when we turned the GPU stress test on the CPU’s frequency did not change only the temperature rose to the usual 80-85 °C.
Surface temperatures on both devices were normal with some cool areas as the palm rest where temperatures were around and below 30 °C and other areas such as above the keyboard and near the exhaust vents where the were around 40 °C.
To sum things up, we can say that the Lenovo Legion Y720 definitely has its perks and is a solid upgrade over the Y520. It provides an overall better build quality and looks. You also get the thermal throttling issues resolved and of course a better GPU which allows higher frame rates. However, it uses the same display as the Y520 which isn’t that good even for a budget device and the price gap is noticeable. We think that the Y720 could be considered as a worthy upgrade however if you are just looking to get into the mobile gaming world or you are seeking a good budget all-rounder the Y520 is your choice.
