MagyarNo Intel or Nvidia required: Lenovo Legion Slim 7 16ARHA7 Gen 7 laptop review
The Legion Slim 7 16 (also marketed as Legion S7 16) is the slimmer version of Lenovo's standard-size Legion 7 16 model. It competes directly with other high-end ultrathin gaming laptops such as the MSI GS series, Razer Blade series, Asus Zephyrus S series, or the Dell Alienware X series. Unlike many of these alternatives, however, the Legion Slim 7 16 utilizes a 16-inch 16:10 form factor instead of the more common 15.6-inch 16:9 aspect ratio.
Our configuration in review comes equipped with the Zen 3+ Ryzen 9 6900HX CPU, 8 GB RDNA 2 Radeon RX 6900S GPU, and 500-nit 1600p IPS display for approximately $1950 USD. Lesser SKUs with the Ryzen 7 6800H, 4 GB Radeon RX 6600S, and 300-nit 1200p IPS display are also available for much lower prices starting at $1300.
Our AMD-powered test unit shares the exact same chassis as the Intel-powered Legion Slim 7i 16. Expect our full review on the Intel version in the coming weeks.

Case — Slim Is In
An easy way to differentiate the between the AMD Legion Slim 7 16 and Intel Legion Slim 7i 16 is to look at their ports as the Intel version has three USB-A ports along the rear instead of only two. Otherwise, it's the same smooth aluminum skeleton from top to bottom.
Keep in mind that only one of the two USB-C ports along the left edge of the AMD model is capable of DisplayPort.

Webcam
The 2 MP camera includes a shutter for privacy, but there is no IR or Hello support.
Maintenance
The bottom panel is secured by eight Philips screws. There is only a single M.2 storage bay and a single DDR5 SODIMM slot.
Accessories and Warranty
There are no extras in the box other than the AC adapter and paperwork. The usual one-year limited warranty applies if purchased in the US.
Display — 165 Hz, 500 nits, 100% sRGB, FreeSync, IPS, Oh My!
The Legion S7 16 utilizes the exact same BOE CQ NE160QDM-NY1 panel as found on the thicker Legion 7 16. This particular IPS panel offers fast response times, a fast 165 Hz refresh rate, full sRGB coverage, and FreeSync to be a high quality panel fit for high-end gaming laptops. P3 colors are limited, however, and Lenovo doesn't offer any OLED options at the moment. It's still one of the best 16-inch panels for gaming purposes nonetheless.

The display is already calibrated out of the box with average grayscale and color DeltaE values of <2 each. Calibrating it even further ourselves would improve the average color DeltaE to <1, but this isn't wholly necessary.

At about 500 nits, the display is brighter than on most other gaming laptops for easier readability when outdoors. Remember to disable AMD Vari-Bright in the Radeon menu or else maximum brightness will drop to just 420 nits when running on battery power.
Performance — Zen 3+ with RDNA 2
Testing Conditions
We set our unit to Performance mode via Lenovo Vantage and Windows prior to running any benchmarks below for the highest possible scores. We also made sure to disable 'Hybrid Mode' in order to fully exploit the discrete Radeon RX 6900S GPU. It's highly recommended that users become familiar with the pre-installed Vantage software as it is the control hub for the system.
Processor
Single-thread and multi-thread CPU performance is approximately 10 percent and 20 percent slower, respectively, than the competing Core i7-12700H. There is almost no difference between the Ryzen 7 6800H and Ryzen 9 6900HX as previously discussed and so the lower-end 6800H configuration can offer essentially the same processor performance as our Ryzen 9 test unit.

Storage Devices — Just One Drive Only
Our test unit shipped with a 1 TB SK Hynix PCIe4 x4 NVMe SSD with sequential read and write rates of approximately 6900 MB/s and 6500 MB/s, respectively. The drive would have no issues maintaining such fast speeds even when stressed as demonstrated by our DiskSpd loop test results below. There is a thermal pad between the SSD and bottom plate of the laptop and so the entire metal bottom of the laptop aids in heat dissipation.

GPU Performance
Graphics performance is most comparable to laptops running on the GeForce RTX 3060 such as on the Dell G16. However, keep in mind that AMD cards are still lagging behind Nvidia when it comes to real-time ray tracing performance. Our Port Royal score, for example, is almost 25 percent slower than on the aforementioned Dell laptop. Thus, you'll want to disable RT when gaming or else frame rates will take a major hit.
The Radeon RX 6800S is still good enough to play modern games at 1080p with medium-to-high graphical settings, but don't expect to reach a stable 165 FPS in most scenarios. Be sure to enable FreeSync via the Radeon menu to reduce screen tearing.

Idling on Witcher 3 for an hour reveals steady frame rates and thus performance throughout except for a single blip where frame rates fluctuated between 65 and 99 FPS. This thankfully did not occur a second time and so it shouldn't be a problem when gaming.

Emissions
System Noise — Not That Loud For The Category
The internal fans are more lethargic than on other laptops meaning they tend to be inactive for longer periods until absolutely necessary. When running 3DMark 06, for example, fan noise would top out at 31 dB(A) compared to 44 dB(A) or even 48 dB(A) on the Legion 7 16 or Asus ROG Zephyrus M16, respectively. Users can browse or video stream more quietly for longer before the fans need to ramp up.
Three fan modes are available on the Vantage software: Quiet, Balanced, and Performance. Fan noise would top out at 47.7 dB(A) and 51.4 dB(A) when running Witcher 3 on Balanced mode and Performance mode, respectively. Performance mode is necessary for exploiting the GPU to its fullest as our Stress Test section below will show. Though Performance mode is the loudest fan setting on the Legion Slim 7, it is still quieter than on many other gaming laptops where the mid 50 dB(A) range is more common as shown by the table below.

Temperature
Surface temperatures are warmest toward the rear and center of the keyboard. The hot spot on the keyboard can reach over 37 C compared to only 33 C on the Dell G16. The keyboard on the Dell is closer to the front edge and thus further from the processors when compared to the Lenovo which can explain some of the temperature differences.
(-) The maximum temperature on the upper side is 46.6 °C / 116 F, compared to the average of 40.4 °C / 105 F, ranging from 21.2 to 68.8 °C for the class Gaming.
(-) The bottom heats up to a maximum of 50.8 °C / 123 F, compared to the average of 43.2 °C / 110 F
(+) In idle usage, the average temperature for the upper side is 24.5 °C / 76 F, compared to the device average of 33.8 °C / 93 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 35.8 °C / 96 F, compared to the device average of 33.8 °C / 93 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.4 °C / 83.1 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.9 °C / 84 F (+0.5 °C / 0.9 F).

Stress Test — Very Warm
When stressed with Prime95, the CPU can be observed boosting to 4.4 GHz and 103 W albeit at a very high core temperature approaching 96 C. Clock rates and board power draw would then drop to 4.0 GHz and 85 W, respectively, in order to maintain a core temperature just below 100 C. Repeating this test on the larger Legion 7 16 with the Ryzen 7 6800H would see a slightly cooler stable core temperature of 93 C.
Running Witcher 3 on Performance mode would result in a steady GPU clock rate, temperature, and power draw of 2247 MHz, 83 C, and 89 W, respectively, versus 2065 MHz, 75 C, and 73 W when on Balanced mode. Running on Balanced mode may be quieter and cooler, but you'll lose out on some performance along the way.
Running on battery limits performance. A Fire Strike test on batteries would return Physics and Graphics scores of 7993 and 18377 points, respectively, compared to 26051 and 25625 points when on mains.

Energy Management — Comparable To GeForce RTX 3060
Power Consumption
Power consumption is an improvement over laptops with last generation AMD parts. The HP Omen 16 with the Zen 3 Ryzen 7 5800H and Radeon RX 6600M, for example, would consume 15 percent more power than our Lenovo when gaming even though it offers 5 to 10 percent slower gaming performance. Overall consumption is generally comparable to many RTX 3060 laptops such as the Dell G16.
We're able to record a temporary maximum draw of 231 W from the medium-sized (~17 x 8.8 x 2.6 cm) 230 W AC adapter when both the CPU and GPU are at 100 percent utilization. Consumption would stabilize at around 157 W after just a few seconds due to thermal limitations.

Battery Life
WLAN runtime is comparable to the MSI GS77 which sports a larger 99 Wh internal battery. Expect just over 6 hours of real-world browsing usage.
Charging from empty to full capacity takes about 2 hours. Unfortunately, the system cannot be recharged via USB-C. We tried two different USB-C adapters — one 130 W AC adapter from Dell and one general 65 W AC adapter — and neither would charge our unit.

Pros
Cons
Verdict — Well-Balanced Ultrathin Gamer
When someone hears "Lenovo", gaming is unlikely to be the first thing they would associate with the brand. Nonetheless, the Legion series of gaming laptops has been steadily improving over the years and the 2022 Legion Slim 7 16 is amongst the best that Lenovo has to offer in the category. The model is quieter than expected and with excellent SSD performance in spite of the ultra-thin profile. Some other ultrathin gaming laptops, like the Acer Predator Triton 300 SE, are much louder and have inferior SSD performance. Even the design of the Legion Slim 7 is more rigid than it looks to be a good reflection of its ~$1500 USD asking price.
The Lenovo Legion Slim 7 16 offers comparable performance to a GeForce RTX 3060 laptop. Its slim profile and AMD hardware balance portability, price, midrange gaming performance, and quality better than most RTX 3060 laptops out there.
There are still plenty of drawbacks to keep in mind. CPU and GPU temperatures in particular are very warm at over 80 C each when gaming and the CPU can be even warmer if at higher utilization. Storage is limited to just one M.2 drive and the keyboard backlight is white only whereas most gaming laptops like the Razer Blade 15 have room for two M.2 storage drives and either multi-zone or per-key RGB lighting. We recommend skipping the Ryzen 9 6900HX SKU if possible as the Ryzen 7 6800H SKU will more than likely offer essentially the same processor performance for less.
