MagyarLenovo Slim 7 Pro X laptop review: The Asus VivoBook 14 alternative
After reviewing the Intel-powered Lenovo Slim 7i Pro X a few months ago, we're now ready to check out its AMD equivalent the Lenovo Slim 7 Pro X powered by the Ryzen 9 6900HS CPU instead of the Core i7-12700H. Otherwise, almost everything else remains identical including the 14.5-inch 3K touchscreen, 55 W GeForce RTX 3050 GPU, and overall chassis design. We recommend checking out our existing review on the Intel model to learn more about the physical features of the laptop.
Current AMD SKUs include the Ryzen 7 6800H or Ryzen 9 6900HS CPU with up to 2 TB of PCIe4 storage or 32 GB of soldered RAM. The same display and Nvidia GPU are fixed across the lineup. Prices start at $1100 USD up to $1500 for our fully configured review unit.
Alternatives to the Slim 7 Pro or Slim 7i Pro include other upper midrange 14-inch laptops like the Dell Inspiron 14 Plus 7420, MSI Summit E14 Flip Evo, Asus VivoBook S14, or the Acer Swift X 14.

Case — Thinner Than Most 14-inch Laptops With GeForce RTX Graphics
Connectivity
The Slim 7 Pro drops the HDMI port as found on the Slim 7i Pro for an extra USB-A port. It also skips out on Thunderbolt support as to be expected.
Communication
Our AMD unit ships with the Realtek RTL8852BE Wi-Fi 6 module instead of the faster Intel AX211 Wi-Fi 6E. Performance is steady but slower by half even after multiple retests on our Netgear AXE11000 router.

Webcam
The 2 MP webcam utilizes an electronic shutter instead of a physical one. IR comes standard for Hello support.
Maintenance
The bottom panel is secured by just 5 T5 Torx screws for easy servicing. Users can remove the SSD, WLAN, and battery modules while RAM is soldered.
Accessories and Warranty
There are no extras in the retail box other than the AC adapter and paperwork. The usual one-year limited manufacturer warranty applies if purchased in the US.
Display — G-Sync and MUX For Non-Gamers
Lenovo employs the same CSOT T3 MNE507ZA1-1 IPS panel for both the Slim 7i Pro X and Slim 7 Pro X and so the viewing experience between the two models is essentially identical. The panel supports most high-end features including a native 120 Hz refresh rate, full sRGB coverage, G-Sync, touchscreen, and low blue light emission. Black-white response times are still relatively slow and so the laptop is not ideal for playing fast-moving games. If OLED is more your fancy for the faster response times and deeper colors, then you'll have to consider the Yoga Slim 9 instead as the Slim 7 Pro X series has no such option.

Lenovo advertises a pre-calibrated display and so our X-Rite colorimeter shows pretty good average grayscale and color DeltaE values of just 3.2 and 2.07, respectively. Nonetheless, we're able to achieve even better results by calibrating the display further ourselves; average grayscale and color DeltaE values would be as low as 1.1 and 0.63, respectively. Our free calibrated ICM profile is above for users to download.

Performance
Testing Conditions
We set our unit to Extreme Performance mode via Lenovo Vantage and Performance mode via Windows prior to running any benchmarks below. Additionally, we made sure to enable discrete GPU mode via the Nvidia Control Panel. The system supports MUX or Advanced Optimus even though it is technically not a gaming laptop.
Processor — Just Shy Of The Core i7
Multi-thread performance is about 5 percent slower than the average laptop in our database equipped with the same Ryzen 9 6900HS CPU. The deficit may be minor, but it's enough to put our AMD CPU behind the Core i7-12700H in the Intel Slim 7i Pro X by about 5 to 10 percent.
Configuring down to the slower Ryzen 7 6800H SKU from the Ryzen 9 6900HS is expected to impact performance by another 5 to 10 percent based on our experience with the Asus ROG Zephyrus G14.

Storage Devices — One Drive Only
Our test unit ships with a 1 TB Samsung PM9A1 PCIe4 x4 NVMe SSD instead of the Micron 3400 as found on the Intel Slim 7 X Pro. Despite this, we can observe performance throttling yet again as shown by our graph below. Maximum transfer rates would be steady at around 6600 MB/s for only a minute or so before falling to as low as 3300 MB/s to suggest insufficient heat dissipation.

GPU Performance — 55 W GeForce RTX 3050 GPU
The mobile GeForce RTX 3050 in our unit performs within single-digit percentage points of the same GPU in the Intel Slim 7i Pro X according to 3DMark. Nonetheless, the Intel version pulls out ahead by 5 to 15 percent when running actual games like GTA V or Final Fantasy XV likely due to the slightly faster Core i7-12700H CPU. You'll definitely squeeze a bit more performance out of the Intel Slim 7i Pro X when gaming.

Emissions
System Noise
Fan noise is dependent on the three Lenovo power profiles: Extreme Performance, Intelligent Cooling, and Battery Saving. The twin internal fans are generally very quiet when browsing the web or streaming video on Intelligent Cooling mode. In this scenario, fan noise would be around 24 to 26 dB(A) against a silent background of 23 dB(A).
Running higher loads like 3DMark 06 would result in a fan noise of 37.4 dB(A) after the first benchmark scene. Fan noise would stabilize at almost 42 dB(A) if running the scene on a loop. If gaming, fan noise can range between 42 and 48 dB(A) which is close to what we observed on the Intel model.

Temperature — Hand Warmer
Surface temperatures can be quite warm due to the combination of a thin profile, H-series CPU, and discrete GeForce RTX GPU. When under load, hot spots on the top and bottom can reach 42 C and 50 C, respectively, compared to just 40 C and 37 C on the Dell Inspiron 14 Plus 7420 when under similar conditions. Hot spots on the Lenovo are toward the keyboard center and rear of the laptop where palms and skin are unlikely to touch for long periods.
(±) The maximum temperature on the upper side is 41.6 °C / 107 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(-) The bottom heats up to a maximum of 49.2 °C / 121 F, compared to the average of 39.1 °C / 102 F
(+) In idle usage, the average temperature for the upper side is 27 °C / 81 F, compared to the device average of 31.2 °C / 88 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 32.9 °C / 91 F, compared to the device average of 31.2 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.4 °C / 84.9 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (-0.6 °C / -1.1 F).

Stress Test
When under Prime95 stress, CPU clock rates and board power draw would boost to 4.1 GHz and 65 W, respectively, lasting for 10 seconds or so. The processor would then eventually stabilize at 3.8 GHz and 54 W in order to maintain a core Tctl/Tdie temperature of 88 C. Maximum boost clock rates are therefore short-lived on the Slim 7 Pro X due to temperature limits. Running this same test on the Dell Inspiron 14 Plus 7420 with the Core i7-12700H would result in a stable core temperature of 80 C in comparison.
GPU clock rate, temperature, and power draw when running Witcher 3 would stabilize at 1492 MHz, 78 C, and 49 W, respectively, compared to 1590 MHz, 74 C, and 50 W on the aforementioned Dell model. The processors in the Lenovo run warmer when under load which partly explain the overall warmer surface temperatures measured above.

Power Consumption
Overall power consumption is slightly higher than on the Intel Slim 7 Pro X when running undemanding loads even though our Ryzen 9 CPU is slower than the Core i7-12700H. Otherwise, the system is just as demanding when running higher loads like games at around 80 to 90 W from the small (~10.7 x 5.6 x 2.7 cm) 100 W AC adapter. Interestingly, consumption is noticeably lower than on the Dell Inspiron 14 Plus 7420 likely because the latter comes with a higher capacity 130 W AC adapter for higher power ceilings.

Battery Life — A Little Shorter
WLAN runtime is shorter than on the Intel version by about an hour despite their similar 70 Wh battery capacities. The competing Dell Inspiron 14 Plus 7420 is also longer-lasting at over 7 hours compared to 6 hours on our Lenovo even though the Dell has a smaller 64 Wh capacity battery.
Charging from empty to full capacity takes under 90 minutes. Note that the charging rate will slow if running demanding loads like games as the 100 W AC adapter is just barely enough for both the CPU and GPU.

Cons
Verdict — Optimized For Price, Portability, and Performance
The Intel version of this laptop includes faster WLAN, slightly faster performance, longer battery life, and Thunderbolt 4 support. It also retails for much more at $400 to $500 USD over the AMD version. If such features are not important to you, then the less expensive AMD version would be sufficient especially since it still offers the same high quality 3K touchscreen and GeForce RTX 3050 graphics.
The Slim 7 Pro X is ideal for users who want an Ultrabook form factor with H-series performance and dedicated RTX graphics all for just over $1100 USD.
When compared to the popular Asus Vivobook 14 series, the Lenovo model lacks OLED options but the chassis has a stronger and more premium feel despite its thinner profile. Content creators and editors who frequently travel will most appreciate the balanced performance and portability of the affordable Slim 7 Pro X.
