Dell Latitude 13 7370 Review: A Sleek Business-Class Ultrabook

Article Index

Benchmarks: PCMark 8, Sunspider, Lame MT

We run several tests to help us gauge a system’s ability to handle computing tasks that range from light duty workloads (like web browsing and messaging) to intensive tasks (audio encoding and video editing, for example).

Lame MT
Audio Encoding on Skylake Mobile

In this test, we created our own 223MB WAV file and then converted it to the MP3 format using the multi-thread capable LAME MT tool, in both single and multi-thread modes. This is what we would consider a "lightly-threaded" benchmark test since it technically only makes use of two simultaneous threads for processing.

Run times are recorded below, listed in seconds. Shorter times equate to better performance.


The Dell Latitude 13 7370’s processor is a Core m5-6Y57. It generates less heat than typical Core i5 or i7 CPUs, but isn’t as powerful, leading to slower encoding times in this test. Even so, the system’s score is respectable for an ultrabook.

SunSpider JavaScript Benchmark
JavaScript Performance Testing

SunSpider is a well-known JavaScript benchmark. The test is designed for comparing browsers (and versions of the same browser) to each other, so it’s worth pointing out that the browser itself has an impact on scores.


Here the Latitude 13 7370 managed to take the lead over other system we have recently reviewed. We used Windows 10’s Microsoft Edge browser to run the test.

PCMark 8
Productivity and System-Level Benchmarking

Futuremark’s PCMark 8 runs the system through typical home and work activities and provides individual scores for certain task categories, rather than specific hardware. The Home test is just as it sounds: a collection of everyday tasks, including web browsing and chatting. The Work test is more demanding and has business-oriented tests, while the tablet’s SSD gets a workout in the Storage test.


The Latitude 13 7370 landed near the middle of the pack in PCMark 8’s Home Accelerated and Work Accelerated tests, but its SSD put up a very strong Storage test score.
