We compare the 15- and 17-inch Lenovo Legion Y740 to help you decide

Thin edge, strong performance

Lenovo Legion Y740 15

More space for more powerful hardware

Lenovo Legion Y740 17

The smaller 15.3-inch Legion Y740 is a beast of a laptop, runs cool under load and looks great while doing it. It might be a plus on an NVIDIA RTX 2070 Max-Q graphics card (GPU), which doesn't really deliver the same performance as the 17.3-inch Y740, but it still needs to meet your portable gaming needs.

The 15.6-inch Legion Y740 is best suited for those who intend to take their laptop often, as it is much more mobile than the 17.3-inch version. However, it comes on top of an NVIDIA RTX 2070 Max-Q, and if you want the best possible performance, you should go for the 17.3-inch Legion Y740, which is located in an NVIDIA RTX 2080 Max-Q. Let us take a closer look at what distinguishes these laptops.

Similar design, different sizes

The 15- and 17-inch Legion Y740s understandably have a similar design. They both have a chassis that is mainly made of aluminum with a plastic rear section for ports, air inlet at the bottom and exhaust at the back and side. The only difference at a glance is the size and weight of the footprint. The 15.6-inch model weighs around 5.1 pounds (2.2 kg) while the 17.3-inch model weighs around 2.9 kg, so if you're worried about portability, the former laptop would be a better fit especially if you take into account the size of the 230 W AC adapter.

Screen hinges are set on the chassis of both models and Lenovo retains the resulting rear edge of the laptop for most ports. On both laptops you get a Mini DisplayPort, HDMI, two USB-A 3.1, RJ45 Ethernet and the Lenovo own charging port on the back, while the left has a single Thunderbolt 3 and a 3.5 mm headset jack and the right has another USB-A 3.1. Even with a lot of external accessories attached, there is not much crowding and cables can run away without causing clutter on a desk.

Both laptops have a little wedge shape to the front, making them look thinner than they actually are, and both have a Legion logo on the lid. The extra space in the keyboard of the 17-inch model is activated with a fully numeric keypad, although the 15-inch model instead has a column of macro keys on the left side of the QWERTY deck that gives gamers some extra flexibility. The only problem with the last setup is that the keyboard is pushed to the right and that you may rub your hand on the touchpad when you use the usual WASD keys for gaming.

Neither the laptop has a mechanical keyboard, but the range is comfortable to use for a longer period of time. Both laptops are equipped with RGB lighting on all buttons and the outlet openings, which can be extensively adjusted with the included Corsair iCue app. Touchpads on both models are underwhelming. They are relatively small and the physical buttons on the bottom can be sensitive. You often have to click right in the middle of the buttons to get a response, but I think Lenovo understands that most people connect an external gaming mouse when it's time to have fun.

Audio systems are also the same on both laptops. There are two down-firing speakers at the front – actually installed on the tapered section – and an extra subwoofer at the back for a little extra sound. Sound quality is not bad on both laptops, but because everything is flashing, no one will blame you if you connect a gaming headset.

Large displays for gaming

The biggest difference between these two laptops, apart from the available hardware, is the size of the screen. With the Y740 17 you get a 17.3-inch screen with FHD resolution, 144 Hz refresh rate and NVIDIA G-Sync compatibility for tear-free images and a smoother overall experience. The interaction is that the larger laptop has a much thicker edge around the screen and a bit of light seems to have run along the edges.

The 15.6-inch Legion Y740 has a smaller screen, but has a thinner edge for a more modern look. It also has a refresh rate of 144 Hz and a maximum of 1080p, and is compatible with NVIDIA G-Sync. By testing the color reproduction, I received 98 percent sRGB and 75 percent AdobeRGB, both excellent results that contribute to an overall colorful image. The 17-inch Y740 scored 97 percent sRGB and 75 percent AdobeRGB, which essentially delivers the same image quality.

Choosing between screens really depends on whether you intend to connect an external monitor often and how often you take the laptop with you on the road. The smaller screen can be slid into a backpack more easily, although you are more likely to use a larger external monitor, while the larger screen is more difficult, but gives you much more real estate to work with. There is also the issue of framing, and if thick edges annoy you, the 15-inch model is probably the better choice.

Performance, battery life and heat

The Legion Y740 models that we reviewed had different GPUs, although the Intel Core i7-8750H processor (CPU), 16 GB DDR4 RAM and 1 TB hard drive (HDD) and 256 GB PCIe SSD (solid-state) state drive) were the same. The 15-inch Y740 comes with an NVIDIA RTX 2060 or RTX 2070 Max-Q (which we reviewed), while the 17-inch model comes with an additional option for an RTX 2080 Max-Q (which we discussed) .

Different GPUs understandably bring different performance, and you can only get the RTX 2080 Max-Q with the 17-inch Legion Y740. If that's what you're focused on, the decision should be simple, although the price / performance ratio can cause a break. The 17-inch model with RTX 2080 that we reviewed costs around $ 1,856, while the 15-inch model with RTX 2070 that we reviewed costs around $ 1,536. The performance is in all respects between these two laptops and we found that the 15-inch model was running cooler and quieter under load.

To get an idea of ​​how well the laptops perform when playing real games, we tested with Metro Exodus and Tom Clancy & The Division 2. Metro Exodus averaged 105.6 FPS (60 minimum and 170 maximum) on high settings without ray tracing or DLSS enabled. The Y740 17 with RTX 2080 Max-Q GPU was an average of 125.6 FPS. With ray tracing and DLSS enabled, Metro Exodus averaged 66.4 FPS (55 minimum and 85 maximum). The Y740 17 had an average of 63.2 FPS, which seems to mean that the RTX 2070 can handle the extra load better.

Tom Clancy & The Division 2 on High preset was on average 73.4 FPS (34 minimum and 84 maximum). The Y740 17 averaged 89.4 FPS. From these results, it is clear that the 15-inch Y740 will deliver a robust gaming experience with high frame rates, although you will not play Ultra without seeing a significant drop in performance.

In terms of overall performance, both laptops can handle their own thanks to a powerful hexa-core Intel Core i7 CPU and 16 GB dual-channel DDR4 RAM. Despite the different battery sizes, the life of the batteries in both laptops is about the same, undoubtedly thanks to the larger screen and the better GPU of the Y740 17. You can count for less than an hour after a full charge during gaming, with about two hours on Normal use when not under load.

Both laptops come with a fast Samsung PM981 PCIe SSD, while the 1 TB hard drive is much slower.

To keep these laptops relevant for longer, you can upgrade or replace the fast SSD, slower HDD and dual-channel DDR4 RAM, for which we have created manuals to help you with the process.

Lenovo Legion Y740 15 is more portable and becomes cooler

The Legion Y740 15 may not have the same RTX 2080 Max-Q option, but the RTX 2070 Max-Q can maintain itself and deliver a great gaming experience. You get a smaller, lighter chassis with an RGB keyboard, complete with a column with extra macro keys, the same selection ports and a 1080p screen with 144 Hz refresh rate and NVIDIA G-Sync compatibility. If you don't mind not having the best GPU and don't mind the smaller size, the 15-inch Y740 is a good choice.

Calm, cool and powerful

Lenovo Legion Y740 15

Smaller but still powerful

An RTX 2070 Max-Q GPU and hexa-core Intel Core i7-8750H CPU ensures that this gaming laptop does not cool down. It is all packed in an aluminum chassis that is competitively priced. If you don't need an RTX 2080 and don't mind the smaller screen, the Legion Y740 15 is probably the better choice.

The Legion Y740 17 is larger and provides more power

The 17-inch Legion Y740 has the option for an NVIDIA RTX 2080 Max-Q GPU, it has an RGB keyboard with full numeric keypad and it has more display property if you do not intend to connect an external monitor to close. It's not as portable as the 15-inch model and it seems louder and hotter, but for those who want the best possible performance, the larger laptop should be the first choice.

RTX 2080 Max-Q and a large screen

It's not that portable, it doesn't run that cool, and it has a thicker edge, but if you're looking for a bigger screen and want the power of an RTX 2080 Max-Q GPU, you have to go with the Legion Y740 17 .
