Lenovo Legion 7 review: a well-armed gaming laptop

Lenovo Legion 7

A separate category in the world of notebooks, machines for notebooks arouse an indisputable appeal. Why bother with a desktop PC and an external display when a laptop brings the same computing power and high-end performance? At first glance, all this seems tempting. And often it is, as our review of the Lenovo Legion 5 Pro proves.

Not stopping there, we decided to take in hand the Legion 7 with the attractive characteristics. Will he really be able to accompany you throughout your adventures? Answer in this test.

Lenovo Legion 7 pricing and availability

The Legion 7 tested here bears the reference 16ACHg6. It is available in France at a price of € 2199. Be careful, however, Lenovo, like many manufacturers, tend to multiply the versions around the same chassis. Their references sometimes differ from each other by a single letter or number: do not be fooled and carefully examine the technical sheet!

  

Here are the main components of the model we received:

  • AMD Ryzen 7 5800H processor
  • GPU: NVIDIA GeForce RTX 3080 16 GB GDDR6
  • RAM: 2 × 8 GB SO-DIMM DDR4-3200
  • SSD: 1 x 1TB M.2 2280 PCIe 3.0 × 4 NVMe

A good soldier for digital creation

What they have in common with digital creation professionals is that they need reliable and efficient equipment. So why wouldn’t a videographer, photographer or graphic designer adopt a machine like the Legion 7 to turn it into a professional workstation?

In fact, nothing prevents it. We have thus replaced the notebook for our workstation usually devoted to video editing, the creation of 3D objects and photo editing. Each time Legion 7 has fulfilled more than honorably the tasks that we had entrusted. Its matt screen allows the user to work in good conditions, the color rendering being much more realistic.

It should be noted in passing that the RAM and the SSD are mounted on supports, facilitating their re = placement. Better still: depending on the configuration, not all RAM and SSD slots are occupied and storage capacity and working memory can be expanded relatively easily.

Ultimately, the main difference between a workstation and a gaming machine is the design. That of the Legion 7 is sober enough to pass easily in an office … provided you deactivate the multicolored and flashing LEDs that equip it!

A well-built legionary

It is an obligatory point of passage: any computer intended for gamers must have an original design and flashing lights in all directions. Why ? The answer is in two words: because. Because it has to be different from the others, because it has to be visible, because it has to look like the cockpit of a spacecraft. And because it’s tradition!

In this regard, the Legion 7 manages to tick all the boxes without being kitsch (a real performance in itself). With a perfectly machined metal body with angular shapes, it inspires confidence while remaining relatively compact. Before opening it, it is difficult to imagine that it has a 16 ” screen on board, its dimensions being closer to a 15 ” notebook. For this, the builder reduced the edges surrounding the slab to the minimum. This one, IPS LCD type, is well worth the detour as we will see a little further on.

Lenovo had the excellent idea of ​​grouping together on the rear face most of the permanent connectors (Ethernet, HDMI, 3 USB-A and one USB-C), minimizing the cables on the sides of the machine. These still house two USB-C (one on each side) as well as a 3.5 mm audio jack port to allow the connection of headphones.

In the end, all that’s really missing is a memory card reader, which Lenovo claims to have sacrificed for lack of space. Note also the presence of a micro-switch intended to completely deactivate the webcam in order not to risk the involuntary sending of a video stream.

The impression of sobriety that the Legion 7 exudes diminishes somewhat as soon as you turn it on. It lights up like a Christmas tree: glow on the sides of the device, halo coming from the ventilation slots and multicolored backlighting of the keyboard.

Fortunately, all of this can be turned off or adjusted to suit his mood using a combination of keys. For our part, we opted for a fixed and bluish backlighting of the keyboard, in order to be able to work without risking an epileptic seizure.

The keyboard, in fact, is made up of two parts. The alphabetical keys are pleasant to use both for traditional tasks and for gaming. Lenovo told us that it had developed the technology to make its use more precise and responsive during gaming sessions.

The numeric keypad is based on the same technology, but has narrower keys making it a little less pleasant… but it at least has the merit of existing! Finally, a slightly eccentric trackpad with generous dimensions takes place under the keyboard. It is precise and has a clickable mechanism with a clear touch.

A remarkable screen

The Legion 7’s display is built around a 16 ” diagonal IPS LCD panel and a resolution of 2560 x 1600 pixels in 16: 10th aspect ratio. A detail rare enough to be underlined, it benefits from a matte finish going against the glossy treatments prevalent on almost all contemporary notebooks. The interest? A more peaceful rendering of colors and above all a relative insensitivity to surrounding lighting.

The default active color profile is very satisfactory and covers 100% of the sRGB space. If necessary, it can be adapted using the X-Rite Color Assistant utility, preinstalled on the machine. By default, the Rec. 709, used in video, is present and we can activate it if necessary.

According to our tests, the screen of the Legion 7 is remarkable in many aspects. We appreciate the virtual absence of afterglow (3 ms according to Lenovo) and the refresh rate of 165 which guarantee a smooth and smooth display. Note also that it supports the Nvidia G-Sync display protocol, very appreciable in video games and that it has Dolby Vision certification. Finally, the brightness announced at 500 nits is more than sufficient for playful use, including in daylight.

The power of the Legion

Like most computers intended for gamers, the Legion 7 is available in several models differing mainly by the onboard processor and graphics card. Our test copy has an AMD Ryzen 7 5800H processor clocked at 3.2 GHz. It has 16 GB of RAM and a 1 TB PCIe M.2 SSD. The display is managed by an NVIDIA GeForce RXT 3080 GPU, along with 16 GB of GDDR6 video memory. Storage is provided by a PCIe M.2 SSD with a capacity of 1 TB.

All this bodes well for excellent performance, which our tests confirm. In terms of computing power, the benchmarks are clear: the Legion 7 thus equipped is a thunderbolt. We’re not going to knock you out with the numbers. It should be noted, however, that it obtains the excellent score of 11,862 points in the multicore Cinebech test, designed to assess the performance of the central processor (1431 points in single-core). 3DMark, in charge of the graphics performance evaluation, gives it 11,220 points, a little more than the Legion 5 Pro equipped with an RTX 3070 GPU and “only” 8 GB of video memory.

We obviously weren’t satisfied with these two results and we used and abused the few months Microsoft Game Pass offered with the machine to play until we thirsty. At no time did we encounter a slowdown issue, including when the level of detail was set to maximum. We also didn’t see a sharp drop in the, backing up Lenovo’s claims about the effectiveness of its heat removal mechanism.

Coldfront 3.0 heat dissipation technology, since that is its name, occupies a significant place in the device. Roughly speaking, the fresh air enters through the side vents and then is exhausted through those housed at the rear.

A well-designed AI recognizes the launch of resource-consuming (and therefore heat-producing) games and adjusts the heat dissipation system accordingly. At no time were we bothered by the noise produced by Coldfront 3.0. While it is noticeable, it is never bothersome (except maybe in a library, but that’s another story). The noise it makes never sounding like a high-pitched whistle.

Pleasant detail, the areas of the machine frequently in contact with the user’s hands have never reached a temperature making use unpleasant.

A voice and a view to be reformed

We weren’t expecting miracles in terms of sound performance: we were partially right. By default, the two pairs of speakers produce a sound that we will call mundane and lacking a bit of punch. To get a better rendering, you have to go rummaging in the settings of Vantage, the preinstalled system utility.

This will give better results in a game session, but the traditional rendering (listening to music or watching a movie) is curiously not really optimized. We are then faced with a rather narrow stereophonic scene, even by activating the settings supposed to optimize the musical and video rendering.

The webcam produces a passable image, nothing more. We find it surprising that a high-end machine like the Legion 7 is only equipped with a 720p sensor offering poor sensitivity to ambient light. Fortunately, this accessory is not the most used on this type of machine.

A legionnaire not too enduring

Powerful processor + high-performance graphics card + large screen = poor battery life. This equation, well known to notebook users, is verified once again with the Legion 7. To obtain the 8 hours praised by the manufacturer, it is surely necessary to put the machine in conditions such that it is almost impossible to operate it. use correctly (Wifi and Bluetooth off, very low brightness, reduced performance, etc.).

Lenovo Legion 7

In real life, when you buy such a machine to play the latest fashionable titles, you will hardly exceed 2 and a half hours of real autonomy. In the end, this is not so serious since the overwhelming majority of potential users are not exactly those seeking extreme mobility above all else.

What we think of Lenovo’s Legion 7

At the end of this test, we can only admire the Legion 7. The couple composed by the Ryzen 7 5800H processor from AMD and the GeForce RXT 3080 GPU is once again very relevant for a machine. intended for gamers. The same goes for the screen, whose matt surface treatment and excellent reaction time make it a more than satisfactory display.

We will not dwell on the audio part, a traditionally mediocre point of this type of machine that is connected most of the time to external speakers. Same thing for the webcam, not really bad, but far from excellent. But to be honest, we royally doesn’t give a damn look at these small defects with indulgence as the rest is successful.
