It wasn’t a long time ago when we tried the fresh out of the oven Legion Y740. It was the 15-inch version of the laptop and we were very curious to see the difference to the Legion Y730 and how the RTX graphics cards are going to put up against their predecessors.

Now, things look settled down, with the RTX series by NVIDIA being on the laptop market for more than half a year. This means we can now compare the Legion Y740 to a wide variety of gaming laptops that house the same hardware. However, we decided that it would be more suitable to get the 17-inch version of the device, so to see if the larger amount of space is proportional to better cooling or not.

What’s in the box?

First, we should note that the box, packing the Legion Y740 17″ is huge. You definitely won’t come unnoticed if you walk out of the store with it. Apart from the laptop itself, inside you’re going to find some paper manuals and second cardboard, containing the 230W power adapter.

Design and construction

This laptop boasts a mostly aluminum build, in contrast to the more wallet-friendly Legion Y540. Additionally, it weighs 2.80 kg (6.2 lbs) and has a profile of 23 mm – both very good figures for a 17-inch gaming laptop. Similarly, though, the top of the lid (where the Legion logo is located) glows when you start the device.

Probably as expected, the lid of the laptop opens easily with a single hand. We are happy, to see that the camera is located on its orthodox location, rather than below the screen as Lenovo did with their 15-inch version of the laptop. Additionally, the lid itself is pretty sturdy as it doesn’t bend too much when you apply pressure on top of it, neither does it flex excessively when you try to forcibly do so. Weirdly, though, the laptop has some pretty sizeable bezels all around its display.

Bigger even than those on the Dell G7 17 7790. Not to mention the ROG Zephyrus S GX701 that didn’t even have a camera. Nevertheless, it is always good to see a Number pad on the keyboard. It just makes it look more… finished. It also has a backlight and even optional RGB one. Well, it is not the most sophisticated keyboards on the market – its travel is short, while the feedback is not the clickiest on the market – below-average performance for a gaming device.

Let’s not forget the touchpad that is placed at a significant distance below the keyboard. However, it is responsive and fast, especially when paired with the 144Hz display.

As you can imagine, the Legion Y740 17″ looks like an enlarged copy of its 15-inch sibling. However, when we turned the device upside down, we were impressed by the size of the ventilation grill. Additionally, there are two speakers on the front side of the plate plus one subwoofer hiding behind the bottom panel.

Ports

As with the latest Lenovo Legion laptops, the Legion Y740 17″ has most of its I/O placed on the backside. There you’ll find the charging port, a USB Type-A 3.1 (Gen. 1) port, an RJ-45 connector, followed by a USB Type-A 3.1 (Gen. 2) port, an HDMI connector, and a DisplayPort. On the left and right side, respectively, are located a USB Type-C Thunderbolt 3 port and a USB Type-A 3.1 (Gen. 1) port.

Battery

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. Lenovo Legion Y740 17″ is equipped with a 76Wh battery – significantly larger than the one on the 15-inch version of the laptop.

However, battery life is still not great – we were able to get less than four hours of Web browsing and around three hours of video playback.

CPU options

You can pick either the 8th or 9th Gen Core i7 H-series processor – the Core i7-8750H and the Core i7-9750H, respectively.

Temperatures and comfort

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average core frequency (base frequency + X); CPU temp.

Core i7-9750H (45W TDP) 0:02 – 0:10 sec 0:15 – 0:30 sec 10:00 – 15:00 min
Lenovo Legion Y740 17″ 3.31 GHz (B+27%)@ 93°C 3.35 GHz (B+29%)@ 93°C 3.00 GHz (B+15%)@ 80°C

Lenovo Legion Y540 2.78 GHz (B+7%)@ 74°C 3.08 GHz (B+18%)@ 90°C 2.87 GHz (B+10%)@ 79°C
ASUS ROG G731 3.38 GHz (B+30%)@ 87°C 3.43 GHz (B+32%)@ 94°C 2.63 GHz @ 73°C
ASUS ROG G531 3.41 GHz (B+31%)@ 95°C 3.23 GHz (B+24%)@ 95°C 2.72 GHz (B+5%)@ 79°C
HP Omen 17 2019 3.44 GHz (B+32%)@ 86°C 2.74 GHz (B+5%)@ 71°C 2.67 GHz (B+3%)@ 71°C

Well, well, well… Six cores proved to be pretty hard to cool down, yet again. The test began pretty comparably to how the stuff went on with the ASUS ROG G731. This basically means – high frequencies at very high clock speed. Despite the similarity at the beginning of the torture test, at the end of the day, we saw a pretty different result – the Legion Y740 17″ was working at 370 MHz higher and around 7C also higher. It is up to you to choose whether it is worth it for you. What we should not, though, is that the HP Omen 17 2019 was working at a very close temperature to ROG G731, but with very, very low fan speeds.

Real life gaming

NVIDIA GeForce RTX 2070 Max-Q GPU frequency/ Core temp (after 2 min) GPU frequency/ Core temp (after 30 min)
Lenovo Legion Y740 17″ 1269 MHz @ 76°C 1236 MHz @ 80°C

As we don’t have a configuration to compare the Legion Y740 17″, since it is the first laptop with the RTX 2070 Max-Q we’ve tested, we can’t show you any direct competitors yet. However, we know the maximum Boost frequency it should be able to reach – 1305 MHz. Honestly, the Legion Y740 17″ wasn’t that far away from that value but at the end of the test, the core was reaching 80C.

Gaming comfort

The Legion Y740 17″ was not louder than most of the gaming laptops we have tested. Temperature-wise, the hottest spot was 48C – just below the “5” key.

Verdict

The Legion Y740 17″ is built for gamers that are not all in the aggressive looks or the gold, red and black combinations. No, in fact, the laptop is combining silver with a somewhat industrial design and a pinch of blue as a backlight on various places. Of course, there is the RGB keyboard, but it looks ever so subtle on this chassis.

We’re also pretty happy with the camera placement this time. Thankfully, Lenovo was not foolish enough to have plenty of space all around the display, and still, put the camera below it. Or even remove it, as some manufacturers that we won’t name… like ASUS. Sadly, the battery life is poor here – less than four hours of Web browsing and around three hours of video playback.

Nevertheless, it’s time for what you’re all here – the performance. If you are in the market for more performance, we would recommend going for a full-blown RTX 2070 experience, and a device that is going to provide you with such, while producing very little noise – is the HP Omen 17 (2019). On the other side – the difference between the RTX 2060 and the RTX 2070 Max-Q, especially inside the Lenovo Legion Y740, is so negligible, that you would want to go for the RTX 2060, instead.

By the way, in order to get the full experience when gaming, you don’t only need good hardware – you need both a fast and punchy display and comfortable input devices. Well, apart from the 144Hz display here, we don’t think you would really love the keyboard. Obviously, if you are playing games you’d connect an external mouse.

However, we suggest connection an external keyboard as well. This lack of amusement of the built-in keyboard of the Legion Y740 17″ comes from the shallow key travel. Yeah, sure, it is good enough for typing, but it is not satisfactory for gaming.

On the other side, the I/O is great, as it has everything you need (except an SD card slot, though). We’re especially happy with the Thunderbolt connection that can’t be seen on the more budget Lenovo Legion Y540.

Pros

  • Good build quality with a huge ventilation grill on the bottom
  • Sleek non-aggressive design
  • Supports Thunderbolt connection
  • 144Hz display option

Cons

  • Uncomfortable keyboard for gaming
  • Poor battery life
  • Lacks an SD card reader
