日本Acer Aspire 7 (A715-43G) review – brings ray tracing to the office
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 5825U (15W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| Acer Aspire 7 (A715-43G) | 3.33 GHz @ 66°C @ 45W | 3.16 GHz @ 66°C @ 37W | 2.80 GHz @ 65°C @ 25W |
| Lenovo IdeaPad 3 (17″, 2022) | 2.85 GHz @ 66°C @ 32W | 2.83 GHz @ 78°C @ 32W | 2.68 GHz @ 77°C @ 26W |
| Lenovo IdeaPad 3 (15″, 2022) | 2.83 GHz @ 71°C @ 32W | 2.83 GHz @ 77°C @ 32W | 2.64 GHz @ 80°C @ 26W |
| HP ProBook 455 G9 | 2.59 GHz @ 64°C @ 27W | 2.48 GHz @ 75°C @ 25W | 1.84 GHz @ 65°C @ 15W |
| ASUS Zenbook 14 OLED (UM3402) | 3.09 GHz @ 79°C @ 44W | 2.82 GHz @ 90°C @ 35W | 2.73 GHz @ 86°C @ 30W |
Here, we see that the cooling solution of this device has absolutely no idea that there is a Ryzen 7 5825U squirming beneath it. Personally, we think that Acer should have taken advantage of that, and given the processor an even higher long-term power limit.

The situation on the graphics front, however, reveals why the manufacturer stuck with the lower power limit on the processor. As you can see, the graphics card is being utilized at its fullest, but can’t match the clock speeds of the MSI Sword 17 (A12UD), despite the same power target.
Comfort during full load
On the other hand, the laptop remains relatively quiet. Well… “not loud” would be a more accurate description. Also, the highest temperature we monitored on the keyboard is about 43°C. Unfortunately, the location of the fans means that the heat is concentrated on the left part of the keyboard, instead of the rarely used right portion.
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. The 53Wh battery lasts for 10 hours and 40 minutes of Web browsing, or 9 hours and 10 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.
