Lenovo Legion Slim 7 Review Portable Gaming That Doesn T Compromise

If you are a gamer who travels around, you might find yourself in a tight spot. Most gaming components perform but do so after weighing in a few kilos at the least. Well, laptop makers in 2022 recognized the need for portability and are coming out with their own lightweight gaming laptops. One such company is Lenovo, which released the Lenovo Legion 7 Slim in India nearly a month ago. And this is a gaming laptop that you can actually carry around without it feeling like a brick. But how does the Legion Slim 7 gaming laptop perform, are there any compromises, or does it actually live up to its promises? I was curious about the same, so I decided to test out the Legion Slim 7 for a few days and see for myself. Here’s what I think about it.

Since I talk about the finer aspects of this laptop in great detail, I have divided the review into various sections, including design, display, performance, build quality, and more. To quickly check out a particular section you’re interested in, use the table below.

Lenovo Legion Slim 7: Specs Sheet

Before I share my opinions on this gaming machine, here’s a quick look at the specs sheet of the Legion Slim 7:

Design and Build Quality

A big part of a portable machine is the design language that goes with it. Lenovo opts for an intricate combination of sleek and professional design. While a first look at the laptop may have you mistaken it for a work laptop, the gamer-esque aesthetic when you open the lid quickly corrects that assumption.

The hinge separates the lid from a small section with light-up icons for the charging and I/O ports that you can use to plug-in devices. The I/O ports are flanked by air cooling vents on either side.

Opening up the lid through the inner cut-out reveals the interiors that look as amazing as the exteriors. The inner body follows the same language and has smooth metal as the base for the keyboard and trackpad, which is of ample size. The display itself has little to no bezels, except for the bottom bezel, which is a bit large. I feel Lenovo could have done away with that and perhaps added a bigger display with a 16:10 aspect ratio. However, the laptop compensates for that with a cool Legion logo and a power button below it, which doubles up as a fingerprint sensor. The hinge of the Slim 7’s display is thin yet strong.

The build quality of the laptop itself is fantastic, and it is durable both in looks and feel. There is little to no body flex even when trying to intentionally do so. While the display itself does wobble around just a bit, I can hardly see a situation when that could be a problem. Plus, for those who might be inclined, the display has a 180-degree hinge and can be opened with just one finger.

Combining a simple yet professional design, robust build quality, and portability that is no-nonsense, the Legion Slim 7 really impressed me when it came to the overall design. If you’re a gamer who travels around a lot and wants a laptop that’s lightweight and also looks the part, the Legion Slim 7 will do it for you.

A laptop with good components, but a bad display may as well have nothing at all. Fortunately, the Legion Slim 7 has the display to back up its design and hardware. The laptop features a 15.6-inch WQHD display with a resolution of 2560 x 1440 pixels and a refresh rate of 165Hz. While you may think color accuracy will be neglected, the display also has 100% sRGB support. Paper specs aside, I decided to test this laptop’s display through a combination of daily media usage, work, and play.

The color accuracy of the display itself is stunning with colors appearing extremely vivid while not being oversaturated. The black tonality matches the same note and I saw deep rich blacks with minimal graying around the display. The same color accuracy was met, no matter whether I was working, gaming, or doing anything else. And if you are someone who wants to mess around with color profiles, the X-Rite Color Assistant lets you select different color profiles for that perfect pick.

If you are someone concerned just about daily work, the Legion Slim 7’s display has your back here too. The text is sharp and legible, while the overall evenness of the display means you can go on working long hours without eye strain.

Packing an AMD Ryzen 7 5800H CPU with an Nvidia GeForce RTX 3060 GPU in a lightweight laptop is no small (pun intended) feat. This is further bolstered by dual-channel 16GB RAM running at 3200Mhz. In terms of storage, you have a 1TB NVMe PCIe 3.0 SSD with read/ write speeds of 3571 and 2969 MB/s, respectively.

My daily usage as a writer is not too heavy when it comes to hardware. However, there are times when stuff ramps up, and I find myself with 20 different tabs open while multiple videos/ songs play in the background. I decided to test out the Lenovo Legion Slim 7 with the same usage, and it impressed me a lot.

The Ryzen 7 5800H-powered laptop handled all the browser tabs and apps I threw at it on the chin. Even while editing images on Paint.net with multiple 4K videos playing ion YouTube n the background, the CPU usage only went as high as 22%. I encountered absolutely no lag or stutter while using the laptop, and the performance was the same on the battery as on the adapter. The RAM too showed the same resilience with the system handling everything perfectly. Even in times when RAM-hungry Chrome used as much as 4GB in one session, I had plenty more to spare of this 16GB 3200Mhz setup and had no problems.

While practical use is always a better indicator compared to benchmarks, I ran them all to see how the Slim 7 handles it. I decided to run the ever-popular Geekbench 5, Cinebench R23, and 3DMark Fire Strike to see how the machine fares. This is what I found.

Running Geekbench 5 was a quick process and gave out some impressive scores. With single-core scores coming at 1415 in the result, the Legion Slim 7 comes right below the Ryzen 9 5900HX, which is a higher-end chip. The multi-core score is equally impressive at 7064, and the CPU is close with the Intel Intel Core i7-9700K which is an unlocked desktop chip.

Cinebench R23

Another intensive benchmark on the CPU, Cinebench R23 is a benchmark that stresses the CPU a lot. I ran the single and multi-core scores to see how it fares. The results were again impressive as the scores surpassed the threshold for daily use and even performance laptops.

The Legion Slim 7 features a fast 1TB SSD that can give and sustain high levels of read/write speeds. I tested the company’s claims with CrystalDiskMark. Running through 5 passes of an 8GB file, the disk gave out read speeds of 3571 MB/s and write speeds of 2969 MB/s, respectively.

While the SSD speeds are not as fast as the latest Gen 4 speeds, that makes little to no difference as performance is still exceptionally high. Besides the high score, all my copy and paste work was almost instant and same was the case for loading time in games and applications.

The Fire Strike benchmark is an intense one and is designed to test out the system’s GPU and see how well it runs. The RTX 3060 laptop GPU has a 6GB GDDR6 VRAM with wattage that can go as high as 100Watts. While that is naturally not the best of what is out there, I can see why Lenovo would cut out TGP in exchange for making the entire setup lighter.

Nevertheless, 3DMark Fire Strike rendered out an impressive score of 18187, which turned out to be better than 82% of all results. Checking further, the results indicate that the Legion Slim 7 can easily run AAA titles at varying resolutions of 2K and FHD with ease and get 65+ and even 100+ FPS in well-optimized games.

Coming to the centerpiece of what the Lenovo Legion 7 is made for, gaming is something the machine should be able to handle easily. The RTX 3060 laptop GPU with a TGP of 100Watts is capable of pushing its full 6GBGDDR6 memory easily. However to get actual metrics, I decided to run a few games like Rainbow Six Siege, Elden Ring, and GhostWire: Tokyo. I decided to use the native 2K and FHD resolutions on Ultra settings to see a varying range of performance. This is what I found:

R6 Siege itself is a well-optimized game in 2022. Nevertheless, it is also a game that utilizes a lot of CPU/ GPU power when run on high settings. Being a Siege player with over 3000 hours clocked in, I am no stranger to playing this game. I decided to test it out in varying settings and the results were very impressive.

As I went roaming around while playing Caveira through Clubhouse, the FPS jumped as high as 159. While the GPU did reach the 80 degree Celsius mark, it didn’t go a step further as the Legion 7’s excellent cooling didn’t let it.

Lowering the resolution to 1920 x 1080, the FPS averaged at 180 frames and went above the screen’s refresh rate. While the textures were naturally downgraded by a bit, the higher FPS delivered even smoother gameplay. As before, the Legion Slim 7 even pushed the FPS as high as 214 which is simply insane.

Elden Ring is making waves as of late, and it was obvious I had to try it out on this machine. However, the devs have also implemented a 60FPS lock PC. Finding a way around that, I tested the game out in various settings.

I further pushed the game down to 1080p on Ultra, which gave me over 100+ FPS and even reached around 120 in certain scenarios. Like before there was no lag or micro stutters and the overall experience was very enjoyable.

While audience reception of GhostWire: Tokyo has been divided, I simply loved finishing this game. Also knowing that the game itself is demanding because of its effects and Ray Tracing, I tested it out.

While Lenovo could have gone a bit further with the wattage, it is a compromise that comes with a lightweight gaming laptop. Despite this, however, the Legion Slim 7 stands tall when it comes to high-performance gaming and offers solid performance to wattage ratio.

Almost every laptop manufacturer these days provides specialized software that acts as a control center for the machine. The Legion Slim 7 is no exception, as the built-in Lenovo Vantage software is the command hub for the device, which comes with Windows 11 out of the box. Featuring real-time CPU, GPU, RAM, and SSD usage, Vantage allows a user to monitor their laptop’s performance constantly.

However, that’s not where its merit lies. Vantage also serves as the home to Lenovo’s custom-tuned thermal profiles that kick in when the laptop needs them. Classified under Performance, Balance, and Quiet Mode, these thermal modes automatically adjust the laptop’s performance and fan speed to fit the situation.

Besides this, Vantage holds an immense number of settings, including one to turn on/off Hybrid mode to your liking. Lenovo Network Boost prioritizes your game whereas overdrive minimizes the response time of the display even further. You can also fine-tune many other settings, including webcam, mic, keyboard, battery optimization, and more.

While I’ve already explained the laptop excels at gaming, I want to quickly talk about thermals. The Lenovo Legion Slim 7 features a turbo dual fan design with multiple exhausts on the sides and back. While mistaken for something small at first, the Slim’s 7 cooling system is surprisingly efficient.

During my hours of playing through various games, the Nvidia GeForce RTX 3060 consistently remained under 80-degree Celsius. Considering the fact that the GPU usage was always 99%, this is seriously impressive. Lenovo’s smart Coldfront Cooling essentially looks the hard work away as the system started its boost cooling as soon as the temps went up. I only needed to put my hands near the vents to see how hard the fans were working.

While the Lenovo Legion Slim 7 is a gaming laptop, that does not mean its keyboard shouldn’t be a nice one to type on. The Legion Slim 7 features an RGB backlight keyboard that is compatible with Corsair iCUE technology. There is also a dedicated numpad that sits snugly on the right side of the laptop.

Gaming on the keyboard itself is as fun as typing. The WSAD keypresses are swift and responsive and all games registered my movements quickly. For the times I felt like having RGB effects on my keyboard, I opened up the Corsair iCUE app and cycled through the various keyboard light effects to add more fun to my gaming experience. I also appreciated the fact that pressing Fn only highlights the function keys on the keyboard, which is handy and cool.

The Legion Slim 7 features a glass surface multi-touchpad that works well. The trackpad itself lacks any texture, which means your fingers easily slide across it. It naturally supports precision gestures that are easy to perform repeatedly. While the clicks on the trackpad do feel a bit rough, I got used to it quickly enough. However, the trackpad is placed in an awkward position to the left which sometimes had me registering annoying misclicks on the laptop. This, I suppose, will take more time to get used to.

If you’re someone who values their security and privacy, the power button houses a fingerprint sensor that works really well. Once registered, the sensor registered my fingerprint in microseconds and the laptop unlocked easily. The power button too has a cool ring light around it that looks nice.

The Legion Slim 7 features a modest set of I/O ports that will work for an everyday gamer. The left side of the laptop houses a 4-in-1 SD card reader with a mic/ headphone jack. That’s it. The right side of the Slim 7 has 2 Type-C ports, which are both DP and USB 3.1 Gen 2 compatible. And those looking for more, the laptop’s back has a pair of USB Type-A ports, with one port having an always-on function, and Power In.

You will immediately notice that the laptop does not have an HDMI or Ethernet port. However, given the focus Lenovo has for the Slim 7, this is hardly a surprise. Given how both the ports will increase the overall thickness of the laptop, the company decided to do away with them. While I can still substitute the HDMI with the DP, I found the lack of a LAN port disturbing.

In terms of wireless connectivity, the Legion 7 Slim does come with Killer Wi-Fi AX1650 and Bluetooth 5.1. However, there are times when one just needs a good old ethernet connection to hook their PC up and download games quickly. Having no port as such means I now have to carry around a USB dongle for the same thing. Depending on what kind of user you are, this may be a problem or a blessing. That I leave up to you to decide.

I don’t expect much from laptop speakers as most models deliver sub-par audio performance and barely get the job done. Even though it’s all crammed in such a small design, the Lenovo Slim 7 has speakers that surprised me. The dual speaker set-up sits at the bottom of the laptop. The speakers are tuned by Harman Kardon and also feature support for Nahimic audio. I tested out the speakers using my daily Spotify/ YouTube playlist and was left impressed.

For starters, the speakers on the Slim 7 can get quite loud for their size. The two bottom firers, when run on 100% volume, have what some would call room-filling sound. There is no audio distortion or crackling even at max volume. The bass, as is usual, cannot be really felt but you do hear some thump from time to time.

The webcam and microphone on the Legion Slim 7 are as standard as they come on laptops. The 720p webcam captures images and videos decently with little quality loss. There is grain here and there as I was expecting. However, combined with its physical privacy shutter, the webcam does a good enough job and will get you through your day-to-day video calls.

The microphone onboard is also average at recording sounds. The recorded sound is clear most of the time but sometimes gets muddy, which is annoying. I also sat in an Echo room to see how well Nahimic Echo cancellation works, and it sadly didn’t make a difference at all. For gamers and users who want to quickly get on video calls, the camera and mic are okay at best. Professional users should get their own gear to connect with the laptop. Check out the best 4K webcams to buy right here.

As a laptop user who loves high screen brightness, I sense the Legion 7 Slim was scared of me and my extensive use. However, the laptop’s 73Wh battery did a decent job of maintaining its life while I worked away. Setting the brightness to 100%, the laptop’s battery at the best power efficiency and moderate use lasted me around 4.5 hours before I had to plug it back in.

While Slim 7 does not offer the best battery life, it was cut short by me watching YouTube videos and occasionally playing with the RGB lights on the keyboard. Lenovo’s Rapid Charge that you need to enable via Lenovo Vantage was helpful as it helped the system charge up quickly and without delay. The provided 230W charging adapter, while not the most lightweight, is slim enough. And I doubt that you will get up to the advertised 8 hours of battery life, but you can stretch it to 6 hours, given you take it easy on the system.
