Next we tested the notebooks in a few real-life applications.
It’s logical that the faster CPU wins when the notebooks are powered from the mains. In the battery mode the notebooks deliver similar performance.
The notebook with the faster CPU wins in both modes here.
Adobe Photoshop produces the same picture. We should note that we couldn’t achieve repeatable results from the Vostro 1400 in this test whereas the U3S would show the same numbers every time.
There’s a small gap between the notebooks in Excel, although the faster CPU wins again.
The difference is small in Winrar, some 5-10% only. This test depends on the memory bandwidth rather than on the CPU frequency.
In the next test a script is used that prepares a video clip for uploading to YouTube. The clip was made out of four video fragments captured from a digital camera. The Dell Vostro 1400 is defeated when the notebooks are powered from the mains.
The results of the final rendering test are proportional to the CPU frequency. The notebooks deliver similar performance in the battery mode just like they did in the video encoding tests.
