DELL XPS 15 9530 performance review

Original DELL XPS 15 9530 11.1V 5500mAh laptop battery 

Inside DELL XPS 15 9530 notebook was a 2.3-GHz Intel Core i7-4712HQ processor, 16GB of RAM and a 512GB solid-state drive. You will have no trouble playing videos, running scans and browsing the Web simultaneously on this machine, but in our performance tests, it fell a bit short of the competition.

On Geekbench 3, which measures overall performance, the XPS 15's score of 11,816 was about 2,500 points higher than the category average of 9,308. However, the MacBook Pro and the Acer V15 Nitro, both of which also have Core i7 processors, notched even higher scores of 13,352 and 12,843, respectively.

The XPS 15's 512GB SSD was fast, duplicating 5GB of multimedia files in 33 seconds -- more than a minute faster than average. Again, though, the Dell was trumped by the MacBook Pro's PCIe-based flash storage (18 seconds), as well as the Acer's more conventional 256GB SSD and 1TB HDD combo (25 seconds).

Similarly, the XPS 15 matched 20,000 names and addresses in OpenOffice in 4 minutes and 9 seconds, which is also more than a minute faster than the average but slower than its closest competitors. The Acer was a few seconds faster (3:55), while the Mac was a minute faster (3:04).
