日本Dell Latitude 14 9430 review – classic performance from a classy product
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.

As surprising as it can be, the Latitude 14 9430 is the most powerful laptop that is equipped with this processor. Keep in mind, you need to keep the lid open by more than 100° in order to give the fan more breathing room.
Comfort during full load
Moreover, the laptop doesn’t get too loud, while the maximum temperature on the keyboard remains well below 40°C.
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. This device comes with a 59.6Wh battery pack. It lasts for 15 hours and 29 minutes of Web browsing, or 12 hours and 34 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.
