日本ASUS Vivobook 15 F1504 (X1504) review – inexpensive laptop that performs well
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
| Intel Core i5-1335U (15W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| ASUS Vivobook 15 F1504 (X1504) | 2.99 GHz @ 2.07 GHz @ 66°C @ 28W | 2.94 GHz @ 2.07 GHz @ 81°C @ 28W | 2.02 GHz @ 1.68 GHz @ 75°C @ 18W |
| Acer Aspire 5 (A515-58M) | 2.05 GHz @ 2.74 GHz @ 61°C @ 47W | 1.81 GHz @ 2.54 GHz @ 64°C @ 40W | 1.22 GHz @ 2.23 GHz @ 61°C @ 28W |
| HP ProBook 440 G10 | 2.39 GHz @ 2.93 GHz @ 93°C @ 50W | 1.51 GHz @ 2.29 GHz @ 92°C @ 30W | 0.94 GHz @ 1.87 GHz @ 72°C @ 19W |
| HP ProBook 450 G10 | 3.41 GHz @ 2.79 GHz @ 94°C @ 48W | 2.80 GHz @ 2.17 GHz @ 94°C @ 31W | 1.87 GHz @ 2.04 GHz @ 81°C @ 23W |
| Acer Swift Go 16 (SFG16-71) | 3.29 GHz @ 2.46 GHz @ 65°C @ 45W | 3.06 GHz @ 2.37 GHz @ 71°C @ 42W | 1.80 GHz @ 1.98 GHz @ 61°C @ 28W |
| Lenovo ThinkBook 14s Yoga Gen 3 | 1.91 GHz @ 1.20 GHz @ 63°C @ 19W | 1.86 GHz @ 0.90 GHz @ 74°C @ 14W | 1.83 GHz @ 0.90 GHz @ 60°C @ 13W |
The Core i5-1335U can maintain almost 3.00GHz for the P cores and 2.07 GHz for the E cores which is a good result given the basic cooling solution of this laptop. In medium loads, the frequencies are (almost) the same but the CPU temperature reaches 81°C. In longer periods of 100% stress, the i5 chip can sustain 2.02GHz and 1.68GHz P and E core clock – a respectable result. The thermals and the power limit are normal.
Comfort during full load
Interestingly, the single fan is almost quiet (in “Performance mode”) unless the CPU isn’t pounded with a 100% load. Even then, the noise isn’t intrusive.
In idle or during light load, the fan isn’t spinning. In normal daily tasks, the fan RPM is ~2700 – 3000 RPM. If the CPU is working hard, the fan will reach its maximum rotating speed of ~5644 RPM. You can check this info in the My ASUS app. The WASD area and the two palm rest zones are always cool enough for normal usage. The rest of the base feels warm, but not too hot to the touch.
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 42Wh battery lasts for 8 hours and 20 minutes of Web browsing, or 6 hours and 40 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.
