日本Acer Swift Edge (SFE16-43) review – has a lot of potential but the cooling solution needs a revamp
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 core frequency (base frequency + X); CPU temp.
| AMD Ryzen 7 7840U (28W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| Acer Swift Edge (SFE16-43) | 2.88 GHz @ 61°C @ 29.5W | 2.60 GHz @ 66°C @ 25W | 1.89 GHz @ 61°C @ 17W |
The laptop is very thin and the cooling looks modest at best. The cooling system is having a hard time taming the 28W Ryzen 7 7840U. The AMD CPU can’t maintain its base clock of 3.3GHz even in light loads. In the long run, the frequency drops below 2.0GHz and the power limit is just 17W. The processor temperature is good no matter the load and that’s the only positive thing in this section.
Comfort during full load
The two fans aren’t loud even in “Performance mode” – yes, you can hear them, but the noise isn’t intrusive. Even in light loads, the center and the left side of the keyboard feel warm which is a result of the thin profile. If the CPU is pounded with heavy stress, the hotspot isn’t too hot for work but it’s on the limit. During normal daily usage, this should not be a problem because the thermals and the noise levels are way lower.
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 laptop is equipped with a 54Wh battery pack. It lasts for 6 hours and 40 minutes of Web browsing or 5 hours and 53 minutes of video playback.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
