Lenovo Legion Y720-15 – Review

Lenovo Legion Y720-15 – Review

Previously, we had a look at the Lenovo Legion Y520. This time it’s the bigger and bolder Legion Y720-15. We weren’t too impressed with the performance delivered, and more on that later. Here’s hoping our experience with the Y720-15 is a more enjoyable one.

We don’t have a confirmed UK price for the Y720-15, although we’d expect a cost of around £1,500 for the pleasure of an i5-7700HQ, Nvidia GTX 1060 6GB and full HD 1080p display.

The key component is the GTX 1060 6GB graphics card. It’s a step up from the GTX 1050Ti on offer in the Y520 model – and in all departments. The GTX 1060 has 1,280 stream processors compared to the 1050Ti’s 768, 6GB GDDR5 compared to 4GB and a higher clock speed at 1,405MHz.

With the GTX1060 6GB onboard, the Y720-15 has good gaming credentials. Lenovo has paired with the in vogue i7-7700HQ. It’s not necessary for a gaming laptop, but it acts as good insurance. Its four cores clocked at 2.8GHz and eight threads will power through most tasks. A 3.8GHz max Turbo adds a little extra when required.

This adds up to a system well at home with smooth 1080p gaming, although 4K and VR will likely be beyond it. Still Lenovo has ensured the key components have decent support from 8GB of DDR4 RAM clocked at 2400MHz. A 128GB SSD and a 1TB HDD provide the storage. It’s a standard set up at the moment, requiring careful consideration of SSD space and the games that use it.

The Legion Y720-15 is a cinch to get connected to WiFi thanks to a Lenovo AC wireless part, and also part of the deal is a slim external Blu-ray and DVD Writer. That adds extra media credentials for the system. and comes as a nice boost. Having said that, it’s not listed in model builds, so may come at extra cost.

Continuity with the Y520 is obvious when looking at the Legion Y720-15. The red detailing is maintained, particularly on and around the edges of keys and the track pad. Yet on the Y720-15 more is made of the theme, befitting an amped up more powerful system.

Extra oomph is obvious in the red grill of the two JBL speakers, and the body of the laptop sat below the display. On the laptop’s practically shimmering lid a red, stylised Y sits amid a funky criss-cross design – faultless but for the attraction of fingerprints.

Flipping the laptop over, you can immediately see extra cooling vents. These join the two copper-finned exhausts on the rear of the base on thermals duty. There’s plenty of potential airflow here, although not particularly if you use the Legion Y20 on any kind of flat surface.

The bulk of the laptop’s casing is a matt charcoal, yet it’s lifted with elements of design that lift expectations. Lenovo’s Nerve Sense software


A chiclet keyboard is about as standard as a laptop with a screen these days. Lenovo has included its own in the Legion Y720-15. It’s very usable, with a middling amount of travel and quite a light actuation profile. While that is great for typing and general use, we’re often wary about the potential for hammered keys with gaming. It’s not too common, but it can happen.

The layout of the keyboard is compact and tidy. We were pleased to see the double height return key of the Y520 return on the Legion Y720-15. It’s not a big deal, but the larger size is preferable.

When it comes to the trackpad, our main observation concerns the trackpad and buttons. While clicking on the pad seems extremely sensitive, the physical left and right buttons seemed less compliant. We soon found ourselves used to the latter, and quickly disabling the former. Finally, we noted the Legion Y720-15 is 0.7kg heavier than the Y520. At 3.2kg this isn’t the lightest laptop even if much of the extra weight is down to a bulkier graphics card.


The GTX 1060 6GB is built to deliver smooth 1080p gaming, and that’s exactly what we saw. At least it’s what we saw after some head-scratching and the realisation of something incredible.

Bizarrely the default (recommended) system resolution of our test Legion Y720-15 was set at 3820 x 2160! Quite why this is the case we’ve no idea, but we’d hope Lenovo sees to it that it’s looked into and addressed.

Resolution resolved, the Legion Y720-15 delivered as it should. An easy average of 50fps in Battlefield 1 was backed by 55fps in Witcher 3. Better, both had minimums of 39fps, ensuring a consistent experience. Fallout 4 delivered an excellent 63fps, and a high minimum of 57fps. Ashes of the singularity’s GPU benchmark delivered 46.5fps. No issues at all there.

All of this was reinforced by Cinebench’s OpenGL score of 88fps, and a 3D Mark Extreme score of 9,302 – in the ballpark of good GTX 1060 performance, and indicative of strong 1080p performance.

For more general productivity performance, Geekbench 4 delivered decent results of 4619 and 13767. Add a PC Mark 8 Home score of 4,054, and we’re convinced that the Legion Y720-15 is well primed for applications. It was tit-for-tat up against another laptop with a Core i7-7700HQ, the MSI GE72. MSI’s machine opts for the less capable GTX 1050Ti 4GB for graphics though, and so is less money overall.

We couldn’t 100% identify the 128GB Samsung SSD drive installed, but some good results mean we’re backing the Samsung 960 Pro as the most likely candidate. A strong read speed of 2133MB/s, and a middling write of 680MB/s prove why NVMe drives are such a draw.

Throughout use the one thing we could feel that was a little high was temperature. This laptop actually hit a high of 87c for both CPU and GPU. That’s higher than we’d like, and a bit close to the GPU’s safe operating limit in the mid-90s.

Activating Lenovo’s Extreme Cooling option in Nerve Sense dropped the GPU to 78c, although with obviously audible exhausts. Lifting the laptop off of the flat surface dropped the temperature to 68c. The problem here is many people game on flat surfaces, but doing so with the Legion Y720-15 seems sub-optimal. Battery life was solid, but nothing extraordinary. This laptop lasted 2h18m in PC Mark 8’s Home battery benchmark, and around 1hr15m when gaming.

Screen and Sound

Starting with the sound, Lenovo has done well. Two JBL speakers produce well-rounded audio, backed by a 3W Dolby Atmos sub-woofer. The result is an engaging acoustic experience that we found crisp, balanced with a good amount of power.

The audio enhanced gaming experiences which visually were fine on the 15.6” IPS display. There’s nothing too exciting about the Legion Y720-15’s screen, but it does a fine job with what appear to be warm colours, average blacks and little obviously negative. This display is anti-glare, but as with others that only means that working in direct daylight is tricky rather than impossible.

Alternative Specs

It’s tricky to speculate about other specs for the Legion Y720-15. We’d assume that they are available, but on checking Lenovo’s website we struggled to find a clear guide as to other models

Conclusion – Lenovo Legion Y720-15

Undoubtedly, if you were considering Lenovo for a gaming laptop this would be in the running. Understandably too, given the Kaby Lake i7-7700HQ and a GTX 1060 6GB. The specifications on offer here are those of a system which should be a shoe-in for capable 1080p gaming. It is. At the same time, it should, and does, eat up day-to-day application tasks with a quick and recommended NVMe SSD to maintain productivity. With both gaming and general use covered it’s thumbs up then. Further good news arrives with a solid design, ergonomics and speaker set up.

Yet our reservations lay in the sub-optimal thermal profile, labelling it as one of the hottest laptops we’ve seen in the last few months. We’re also confused as to why Lenovo would set a 1080p gaming system at a default ‘4k’ resolution. That’s not the laptop’s fault of course, and if anything, it tried to soldier on. In all, it comes to this: As the sum of its parts, this is a solid system. However, it’s likely not for you if you like your laptops kept cooler. Or if you’re against the idea of a laptop stand allowing more ventilation. A good laptop this is, but we feel it could have been better.
