Lenovo Legion Slim 7-16IAH7 laptop review: slim Legion notebook is just as excellent with Nvidia & Intel
In the past few years, Lenovo has managed to turn its "Legion" gaming brand into quite a popular name on the laptop market. The Legion 7 series comprises high-end models available in both regular and "Slim" versions. Today, we will be reviewing one such slim model: the Lenovo Legion Slim 7 16IAH7 (also known as the Legion S7i).
The abbreviation "IAH" already tells you something about the laptop's specs: "I" stands for Intel and "AH" for Alder Lake-H. This is important because there is also an AMD-based variant of the Legion Slim 7, which we already reviewed. So which of the two models performs better? This is certainly one of the most exciting questions to be answered in this review.

Case: Lenovo Legion with grey aluminium design
Whilst the cheaper Lenovo Legion 5 laptops are partly made of plastic, the Legion Slim 7 has a mostly aluminium construction. The display bezel is the only plastic component on the chassis. In terms of design, the Legion Slim 7 is considerably more restrained than the thicker Lenovo Legion 7. Lenovo opted not to give the Slim 7 flashy RGB lighting and instead went with a dark-grey colour scheme that wouldn't look too out of place on a business laptop. The white keyboard lighting also calls to mind Lenovo's ThinkPad business series. The LED on the power button is one of the very few splashes of colour on the device. Depending on the performance profile selected, it can light up in either blue (battery saving mode), white (balanced mode) or red (performance mode).
Despite having a simpler design, the S7 is still easily recognisable as a Legion laptop. Lenovo has done a good job when it comes to quality: The fit and finish is perfect, and the aluminium chassis is also very regid. Even the display lid is relatively sturdy despite its thinness and the slim bezel.
The hinges are attached to the base section and allow the laptop to be opened to 180 degrees. However, we wouldn't recommend folding the screen on our review unit back by more than about 135 degrees – otherwise images on the display will become distorted. At least the hinges hold the screen firmly in place and are also so well tuned that the laptop can be opened with one hand.
The Lenovo Legion S7i Gen 7 has the slimmest chassis amongst all the gaming laptops in the comparison. At just 16.9 mm thin, the device is almost in the ultrabook territory. But the story is different with its weight. Although not terribly heavy, the Lenovo Legion Slim 7 is also not a featherweight at 2.2 kg (4.85 lb). The Asus ROG Zephyrus M16 is marginally lighter than the Slim 7.
Specifications: Legion S7i with Thunderbolt 4
Unlike the AMD variant, the Lenovo Legion S7-16IAH features a Thunderbolt 4 port. It also comes with a great selection of ports (distributed across its sides and back) but lacks an RJ45 socket. Those who want an Ethernet port can take a look at the regular, "non-Slim" Lenovo Legion 7.
SD card reader
The SD card reader doesn't allow a card to be inserted all the way in, meaning it is not suitable for long-term storage expansion. The laptop delivered an average result in our benchmarks, performed using our AV Pro MicroSD V60 reference card.

Connectivity
The Lenovo Legion Slim 7-16IAH features a Killer Wi-Fi 6E AX1675i, which supports the new Wi-Fi 6E standard. In our testing, this 2x2 module delivered high transfer rates with a few minor fluctuations during the transmit test. Technically, this should also apply to the Wi-Fi 6E mode, but the laptop was unable to find the 6 GHz network – probably due to a driver issue.
Webcam
The Legion Slim 7 can be configured with either a 1080p or a 720p webcam. Our review unit comes with the higher-resolution option. In spite of this, the webcam performs poorly and produces relatively pixelated and noisy images.
Accessories
Lenovo didn't include any accessories with the Legion Slim 7 apart from a 230-watt charger with a Slim-tip plug.
Maintenance
Theoretically, the Lenovo Legion Slim 7i can be opened and upgraded. To do so, you have to remove the base panel, which is secured by eight screws and numerous clips. We said "theoretically" because we couldn't open the device even after several attempts. It wasn't possible to undo the clips without risking damage to the chassis. Nonetheless, the layout of the internals should be similar to the one in the AMD version, so we have borrowed a corresponding image from that review.
Besides the M.2 2280 SSD, both the SODIMM RAM and the Wi-Fi module are upgradable. The battery can likewise be replaced.
Warranty
Lenovo offers a 24-month warranty with bring-in service on a Lenovo Legion S7 purchased in Germany. Warranty periods may vary by country. For instance, customers in the US will only receive a one-year warranty by default.
Input devices: Gaming laptop without RGB keyboard
Keyboard
The chiclet keys on the keyboard are dark grey to match the colour of the chassis. As previously mentioned in the case section of this review, Lenovo decided not to use any of the usual RGB gimmicks found on gaming laptops, instead giving the keyboard a bluish-white backlight. That said, an optional RGB backlit keyboard is available at an extra cost.
The keyboard occupies almost the entire width of the chassis and has a numeric pad. One noteworthy feature is the extra-large arrow keys, which you don't see quite often on laptops. Whilst this is nice, we didn't like the narrow enter key as much. Overall, the Lenovo Slim 7i is pretty pleasant to type on. The keys have about 1.5 mm (0.06") of travel and a crisp actuation point and thus don't feel mushy. Furthermore, the metal chassis is sturdy and prevents the keyboard from flexing during typing.
Touchpad
Measuring 12 x 7.5 cm (4.72 x 2.95"), the touchpad is adequate, but we feel it could be slightly larger. The glass trackpad has a smooth, matt surface that feels premium and allows fingers to slide across very effortlessly. We are less impressed by the traditional click mechanism of this clickpad (actuated by pressing down the lower zone). The reason is that the touchpad makes pretty loud clicking sounds, which can be annoying. However, this is our only gripe with the touchpad; the software implementation of features such as multitouch gestures is impeccable, and the mouse pointer can be controlled with very high precision.
Excellent WQXGA display capable of 165 Hz refresh rate
All the display options available for the Legion S7i are matt IPS panels with a 16:10 aspect ratio and a diagonal of 16 inches. They differ in terms of their resolution and feature set:
- WUXGA (1,920 x 1,200), 300 cd/m², 100% sRGB, 165 Hz
- WQXGA (2,560 x 1,600), 500 cd/m², 100% sRGB, 165 Hz
- WQXGA (2,560 x 1,600), 500 cd/m², 100% sRGB, 240 Hz
Our review unit exceeded the claimed peak brightness of 500 cd/m², with the screen getting as bright as 523 cd/m². The display has an average peak brightness of 494 cd/m², meaning the Lenovo Legion S7-16IAH7 has the brightest screen in the comparison.
Thanks to the 165 Hz refresh rate, content on the screen looks very smooth in motion, which is ideal for gaming. Moreover, the display also has low response time for an IPS panel.

* ... smaller is better
We used CalMan and the X-Rite i1Pro 2 colorimeter to analyse the display. The X-Rite i1 Profiler was also used in conjunction with the i1Pro 2 to calibrate the screen. The screen benefited from calibration and achieved significantly lower Delta E values. This means that the colour reproduction became more accurate. As always, there is a link in the grey box above for you to download the colour profile created by us.
The display's colour coverage isn't exactly amongst the best. Even though the smaller sRGB gamut is almost fully covered, things are different with the wider P3 and AdobeRGB colour spaces. The more expensive Acer Predator Triton 500 SE has superior colour coverage, which is particularly useful for photo editing.
The Lenovo Legion S7i is very usable outdoors thanks to its matt display and high screen brightness. It makes for a great laptop to take with you to an outdoor LAN party.

Great performance with Nvidia RTX and Intel Alder Lake
Lenovo offers three processor options for the Legion S7-16IAH: the Intel Core i5-12500H, Core i7-12700H and Core i9-12900H. The laptop also has the same number of GPU options (this time around from Nvidia): GeForce RTX 3050 Ti, GeForce RTX 3060 and GeForce RTX 3070.
The Lenovo Legion S7 comes with 8 GB of soldered DDR5-4800 RAM as well as a SODIMM slot (our review unit has an 8 GB module). Lenovo sells the laptop with up to 24 GB of RAM, but it should be possible to increase the amount of RAM to 40 GB. There is a M.2 2280 slot for storage.
Test conditions
The processor in the Lenovo Legion S7-16IAH can draw as much as 100 watts of power in short bursts. It could go even slightly higher at absolute peak loads. Under sustained load, power usage is capped at 70 watts in silent mode, 80 watts in auto mode and 90 watts in performance modes. You can toggle between the power profiles by pressing Fn + Q.
Processor
The Intel Core i7-12700H is part of the Alder Lake line-up. It uses the new hybrid architecture with two types of cores: six large performance cores and eight small efficiency cores. The CPU has a total of 14 cores and 20 threads because the six large cores support hyperthreading. Its TDP is typically around 45 watts, and clock speeds range from 2.4 to 4.7 GHz for the P-cores and 1.8 to 3.5 GHz for the E-cores. For detailed benchmark comparisons, you can refer to our CPU comparison list.
The Alder Lake processor delivers excellent performance in the Lenovo Legion S7i. This Lenovo laptop is the fastest of all the devices with a "H" processor in our comparison and even beats the AMD variant of the Legion Slim 7. The HP Omen 16 took a tiny lead initially but fell behind under sustained load. The Asus ROG Zephyrus M16, which has an older Tiger Lake chip, is considerably slower. However, if you want maximum CPU performance, there is an even faster option with Intel's "HX" processor. The heftier Lenovo Legion 7 brings roughly 22% more power to the table on average with its more powerful cooling system.
Performance mode is not available when the laptop is running on battery. In this case, CPU power usage is limited to around 80 watts in auto mode. In Cinebench R20, the Legion S7i received a score of 4886 when unplugged – equivalent to a 28% decrease in performance.

Graphics card
The GeForce RTX 3060 is a mid-tier card in Nvidia's mobile GPU line-up. The GA106 chip has 3840 shader units and 6 GB of dedicated GDDR6 RAM. You can find more data on this and many other graphics cards in our GPU list.
The other laptops in this comparison are equipped with significantly more powerful GPUs. That is why the Lenovo Legion S7i performed worse than most of them in the 3DMark tests. The only exception is the Asus ROG Zephyrus M16, which ran slower despite having a GeForce RTX 3070.
The GPU performance is noticeably limited when the laptop is unplugged. On battery power, the Lenovo Legion S7i only managed to achieve a score of 9412 in the 3DMark 11 graphics test – 65% lower than when plugged in.

Gaming performance
It is not a huge surprise that the Lenovo Legion Slim 7i was slower than the other devices in the comparison group during the gaming benchmarks, considering all of them have faster GPUs. Nevertheless, the Legion S7i was only marginally slower compared with an average RTX 3060. It also has enough GPU performance to effortlessly run modern games at 2K (2,560 x 1,440) and high settings.
