Performance Test
The Dell Inspiron 14 5488 boasts enhanced eighth-generation Core i7-8565U processor, MX150 independent graphics, 8GB DDR4 2400MHz memory, and 256GB SSD. With high specification, the Inspiron 14 5488 has good performance among ultra-thin laptops.
Processor
The enhanced Core i7-8565U processor has four cores and eight threads. Its main frequency is 1.8GHz, which can reach up to 4.6GHz. Moreover, its TDP is 15W. On CineBench R15, the processor’s multi-core score reaches up to 653cb, and its single-core score is 179cb. According to the test result, the i7-8565U processor has excellent performance.
In addition, the i7-8565U processor’s single-core score has exceeded the standard-voltage i7-7700HQ processor’.
SSD
The laptop features a Hynix BC501 NVMe 256GB SSD. On CrystalDiskMark 6.0.0×64, this SSD’s sequential read speed reaches 1642.6MB/s, while its sequential write speed reaches 810MB/s. The test result shows that the BC501 NVMe 256GB SSD has good write and read performance.
Heat Dissipation
This ultra-thin laptop’s vent is placed on the hinge.
We use AIDA 64 to test the laptop’s heat dissipation performance. After an hour, we use a thermal imager to detect its temperature. From the picture, we can see that the highest temperature of the keyboard is 59.6℃, while the highest temperature of the back cover is 52.3℃.
Battery Life
It sports a 42Wh battery. We adjust the screen’s brightness to 80%, volume to 20%, and close the Bluetooth and dispositioning, and then play a 1080p video. After an hour, the battery’s power has dropped 11%. According to this result, we can infer that the laptop can work about 10 hours for daily use.
Memory, M.2 SSD, HDD Upgrade
During the disassembly process, I find that the three screws near the hinge can’t be removed. After taking out other screws, the back cover is removed. Then, its internal structure can be seen.
This laptop reserves a place for a 2.5-inch SATA hard drive, so the user can buy a 2.5-inch SATA HDD to increase its capacity.
It features a BC501 NVMe 256GB SSD from Hynix. This M.2 SSD is near to the fan. The user can buy a 2260/2280 M.2 SSD to upgrade its capacity.
