New CPU name, old CPU performance: Lenovo Slim 7 Pro Ryzen 7 7735HS laptop review

Lenovo has refreshed its ultralight Slim 7 Pro series this year with the new Zen 3+ Ryzen 7 7735HS CPU to replace last year's Core i7-12700H and Ryzen 9 6900HS options. Graphics has been slightly upgraded as well from the 4 GB GeForce RTX 3050 to the 6 GB version of the same GPU. Other than some internal changes, however, the exterior chassis remains almost exactly the same. We recommend checking out our existing two reviews on the Yoga Slim 7i Pro X and Slim 7 Pro X to learn more about the physical features of the series.
SKUs range from the Ryzen 7 7735HS to the Ryzen 7 7840HS CPU with a 14.5-inch 2.5K (2560 x 1600) or 3K (3072 x 1920) IPS touchscreen covering sRGB and DCI-P3, respectively. All options carry 16 GB of soldered LPDDR5 RAM and a 6 GB GeForce RTX 3050 GPU at the moment. Our particular configuration is the lower-end SKU retailing for $1200 USD at Best Buy.
Competitors to the Slim 7 Pro include other upper midrange 14-inch multimedia laptops like the Asus VivoBook 14, Honor MagicBook series, Dell Inspiron 14 Plus 7420, or the 13.5-inch HP Spectre x360 13.5.

Case — Same Slim Spectacle
The positioning of the USB-A port and power button along the right edge of the laptop has been swapped. Additionally, one of the USB-C ports along the left edge now supports USB4 meaning native compatibility with most external GPU docking stations. Otherwise, port options remain the same.

The MediaTek Wi-Fi 6E MT7922 comes standard for 6 GHz Wi-Fi 6E and Bluetooth 5.1 connectivity instead of the usual Intel AX series. Unfortunately, our particular review unit would have issues recognizing our Asus AXE11000 Wi-Fi 6E network even after multiple retries and so we are only able to record its Wi-Fi 6 performance.

Webcam
The 2 MP webcam, IR sensor, and electronic shutter come standard once again. However, image quality appears to be blurrier than before. Competing models from HP like the Spectre 13.5 ship with higher quality 5 MP webcams in comparison.

Display — 2.5K 90 Hz Standard
Our review unit sports the lower resolution 2.5K 2560 x 1600 panel instead of the 3K 3072 x 1920 panel as found on last year's Slim 7 Pro X or Slim 7i Pro X. Even so, contrast is just as good and the glossy screen is still very sharp and with no graininess issues. Response times are a little faster for less ghosting as well, but maximum brightness is slightly dimmer dimmer; Lenovo advertises a brightness of 350 nits for the 2.5K panel vs. 400 nits for the 3K option.

Though it's not poorly calibrated out of the box, the color accuracy has room for improvement especially since it covers sRGB in its entirety. Average grayscale and color DeltaE values by default are 4.6 and 3.01, respectively. We're able to minimize these deltaE values to just 1.4 and 0.83, respectively, after a proper calibration with our X-Rite colorimeter. Owners can apply our calibrated ICM profile above to improve color accuracy.

The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 33 % of all devices are better. This means that the measured response time is better than the average of all tested devices (22.3 ms). | ||

The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 33 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (35.1 ms). |

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19035 (minimum: 5 - maximum: 3846000) Hz was measured. |
Outdoor visibility is acceptable when under shade where glare is more tolerable. If under brighter conditions, the glare becomes more difficult to ignore and onscreen content can appear too washed out. HP offers displays that can be over 2x brighter on some of its 14-inch EliteBook models if outdoor visibility is a concern.
Performance — New Ryzen 7 7735HS CPU
Testing Conditions
We set our unit to Performance mode via Windows and Extreme Performance mode via Lenovo Vantage prior to running the benchmarks below. Lenovo has redesigned its Vantage software this year and so all the settings and toggles have been annoyingly rearranged. The three performance profiles, for example, are under two different submenus.
Advanced Optimus and G-Sync are not supported.
We encountered a bug on our unit where the system would not properly wake from sleep at times. A hard reboot would then be required.
Processor
As impressive as the high-end Zen 4 Ryzen 7 7945HX may be, the lesser midrange Zen 3 Ryzen 7 7735HS feels like a simple rebrand of last year's Ryzen 7 6800H. Multi-thread performance lies in between the slower Ryzen 9 6900HS and faster Core i7-12700H. Single-thread performance is more disappointing with its 30 percent deficit behind the Core i7-12700H. Even the more power-efficient Intel Core i7-1260P can outperform the Ryzen 7 7735HS in single-threaded workloads.
Performance sustainability is nonetheless very good. When running CineBench R15 xT in a loop, final scores would remain steady throughout whereas the Core i7-12700H in the Dell Inspiron 14 Plus or Alienware x14 would experience steeper performance drops as shown by the comparison graph below.
