Lenovo Yoga Slim 7 Pro X (14″, 2022) review – compact and surprisingly powerful
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average P-core frequency; Average E-core frequency; CPU temp.; Package Power
| AMD Ryzen 7 6800HS (35W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| Lenovo Yoga Slim 7 ProX | 3.59 GHz @ 70°C @ 63W | 3.50 GHz @ 85°C @ 57W | 3.49 GHz @ 86°C @ 54W |
| ASUS ROG Zephyrus G14 GA402 | 3.81 GHz @ 83°C @ 81W | 3.77 GHz @ 89°C @ 80W | 3.71 GHz @ 96°C @ 79W |
| ASUS ROG Zephyrus G15 GA503 (2022) | 3.83 GHz @ 82°C @ 75W | 3.81 GHz @ 88°C @ 75W | 3.80 GHz @ 90°C @ 75W |
Interestingly, when it comes to cooling performance, the Lenovo Yoga Slim 7 ProX isn’t too far behind compared to the two gaming machines that are listed in the table above. The CPU clocks are a bit lower than the two bigger ASUS devices but on the other hand, the CPU thermals are better – nice. Speaking of the Ryzen 7 6800HS frequencies, here, they are almost the same no matter the load which leads to stable and sustained performance and that’s a great achievement for such a compact and thin laptop. Unlike the Lenovo Yoga Slim 7i ProX the AMD sibling has no problems cooling down a powerful CPU like the Ryzen 7 6800HS while the Intel iteration is struggling with the Alder Lake-H. When it comes to thermals and cooling, the AMD variant of this notebook is better.
Comfort during full load
We’re not done yet with the good news – the laptop isn’t producing a lot of noise even under maximum CPU load and it’s dead silent in idle or when you’re using it for something casual like Web browsing. The WASD section and the palm rest area are cool enough for comfortable usage.
Battery
Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. Our configuration is equipped with a 70Wh battery pack. It got us through 9 hours and 5 minutes of Web browsing, or 10 hours of video playback.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
