Dell Latitude 7400 2-In-1 Review: A Lethal Weapon For Road Warriors

Considering its relatively powerful hardware, clean OS image, 16GB of RAM, and snappy solid state storage, not surprisingly, the Dell Latitude 7400 2-in-1 came in near the top in several benchmarks and other tests; it especially crushed the battery life test and came in near the top in PCMark 10 as you'll see in just a bit.

Neither the SunSpider results nor the Cinebench results were all that impressive, but in the real world, the machine handled everything we threw at it with no problems, handling multiple audio and video streams while also displaying multiple Chrome tabs and simultaneously running Microsoft Word and Excel poses no problem for a machine of this caliber.

ATTO Disk Benchmark

We used ATTO to quickly get a handle on the 7400's storage capabilities, and the results were more than acceptable. The test showed peak write speeds of 2.65GB/s and read speeds of 2.85GB/s. IOs also looks good. Both results were head and shoulders above the HP Envy X2, which turned in read speeds in the 474MB/s range, and which also uses an M.2 SSD, but is of the SATA variety.

Cinebench R15

Cinebench R15 is a 3D rendering test that can be used to out the CPU and GPU through their paces...

Here the 7400 2-in-1 landed near the top of the pack, generating scores of 600 (CPU) and 54.42 (GPU), placing it just below the HP Envy x360 and just above the Dell Latitude 7390. 

UL PCMark 10

PCMark 10 is one of the most wide-ranging of our tests, rating productivity and mixed usage, and generating four scores: Essentials (Web browsing, videoconferencing, and app startup times), Productivity (office apps), Digital Content Creation (photo and video editing and rendering) and an overall score.

Here the Dell Latitude 7400 2-in-1 acquitted itself well, coming in near the top of our set of test machines in almost every test. It generated an Essentials score of 8,739, a Productivity score of 7,343, a Digital Content Creation score of 3,022, and an overall score 4,149 which led the pack. In these tests, the 7400 beat out the Lenovo X1 and the HP Elitebook 830, both of which also had Core i7 processors and both of which also utilized Intel UHD 620 graphics.

SunSpider

SunSpider is an online JavaScript benchmark that determines how well a system handles the core JavaScript language (it ignores APIs, DOM, special add-ons, etc.).
Here, the Dell Latitude 7400 2-in-1 landed smack in the middle of the pack, generating a score of 82.3, placing it just above the HP Spectre X360 and just below the Razer BladeStealth (all core i7 machines).
