TOP-NOTCH PERFORMANCE

AND BATTERY LIFE

The Dell Latitude 7400 2-in-1 proves you don’t

have to sacrifice performance for long battery

life. While our review unit topped the heap in

some tests, it finished no lower than the middle

of the pack in others.

It also delivered the

best graphics

performance we’ve

seen outside of a

dedicated GPU. The

selling point,

however, was the

battery life, which

exactly matched that

of a Snapdragon

850-powered

tablet, the Samsung

Galaxy Book 2 (go.

gbk2), while

providing the

performance of

notebooks powered

by Intel Core

microprocessors.

We test using a

mix of synthetic and

real-world

benchmarks. The latter category loads apps like

GIMP and OpenOffice to simulate real-world

workloads. These latter tests are based on

PCMark 8, which use a battery of different apps

grouped into three benchmarks: PCMark 8

Work, Home, and Creative.

While Work emphasizes office tasks such

as video calls, spreadsheets, and word

processing, the Home test begins steering

the workloads toward web browsing and

We combined all three PCMark tests into one grouping, ranked by performance,

with the Dell Latitude 7400 debuting in first place. With a few laptops we

went no further than the PCMark Work test. Note the Qualcomm Snapdragon-

powered Samsung Galaxy Book 2 at the bottom.
