Dell XPS 13 9370 - ATTO Disk, SunSpider, PCMark, And Cinebench
ATTO Disk Benchmark, Testing NVMe Solid State Storage
The 1TB Toshiba NVMe SSD employed in the XPS 13 we evaluated peaked at about 3GB/s reads (at the 1MB mark), with writes just shy of 1GB/s. As you can see, with larger transfer sizes (past the 4MB mark), performance drops off a bit in terms of read speed, but still hovers around the 2GB/s mark.
Sun Spider And Cinebench
There are a couple of things we should mention in regard to the latest XPS 13's Cinebench performance. First, is obviously its lead over all of the other systems. The combination of Dell's Power Manager optimizations and the more capable cooler in this system allow the Core i7-8550U to really stretch its legs, which results in the best score of the bunch in the multi-threaded CPU test. Over and above this result, however, we should also mention that the new XPS 13 can maintain much of this performance over time. Whereas some thin and light systems throttle significantly with long, highly-taxing workloads that can saturate their cooling hardware, the XPS 13 can maintain most of this performance for the long haul. For example, after the tenth straight Cinebench run the new XPS 13 was scoring in the mid 630-range.
