At the end of June, Asus revealed refreshed ZenBooks, which immediately impressed me with their design, elegance, but also their equipment and compact dimensions. We tested its predecessor, ZenBook 14 UX431F, which looked a bit awkward and didn’t interest me much except for the price. However, the new UX425 is a completely different story. Will it dare to be the title of the best ultrabook with the 10th generation Intel Core we have tested?
Memory and disk tests
The lower frequency of 3200 MHz memory was reflected in speed where the ZenBook lags behind Dell and Lenovo by about 15%, which have a higher 3733 MHz frequency. Interestingly, however, the results are identical, or even better, than the Swift 3, which has LPDDR4X 4266 MHz RAM. Swift 5 with 2667 MHz lags behind ZenBook by up to 20%. Asus latency is almost identical to Dell and Lenovo and significantly better than both Acers.
If I can blame something, it is the SSD speed, which I have been noticing for a long time with Asus products. Unless it’s a completely top model, speeds are usually average to below average. In this case, 1777/976 MB/s is not catastrophic in any way, but the write could really be better. The reason is the use of the Intel 660p SSD, which is not one of the fastest SSDs on the market and the performance is quite far from the commonly used ones from Samsung. However, replacing a faster or larger SSD is a matter of minutes. It can also be assumed that the 1 and 2 TB versions will have better speeds.
