No 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.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. |
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.
