APRIL 2020 PCWorld 57processor. Still, performance is in line with
expectations, beating out Intel’s
10th-generation Core i5 processors and last
year’s 8th-gen chips.
Our HandBrake test uses the popular free
utility to encode a large video file, a good
way to stress a CPU. As with the PCMark 8
test, The Yoga C940 14 didn’t get the job
done as quickly as the XPS 13 did—or the
Ryzen 5-powered Walmart Motile M142, forProductivity performance is a hair behind other
premium 2-in-1s with 10th-gen Intel Core-i7 CPUs.
The Yoga C940 14 makes pretty quick work of
video encoding, though again it’s behind some of
its direct competitors.
Benchmark testing bears this out. While
the Yoga C940 14 is slightly behind some of
its convertible competitors in raw
performance, it’s a clear cut above last year’s
2-in-1 laptops and offers excellent battery life.
In PCMark’s Work 2.0 benchmark, which
simulates a gamut of productivity tasks, the
Yoga C940 14 didn’t score as well as Dell’s
XPS 13 2-in-1 or HP’s Spectre x360 13t, both
of which use the same Intel Core i7-1065G7
