APRIL 2020 PCWorld 69impact on performance we used the newest
version of HandBrake and encoded a 4K file
using the 1080p 30 fps H.265 preset. As you
can see the GTX 1650 comes in a bit faster.
More important is the flexibility.
Application support for Intel’s QuickSync and
Nvidia’s NVENC varies widely, so having it as
an option at all is likely more important than
just how fast it is.
BATTERY PERFORMANCE
Our last standard benchmark is a battery life
test. For that, we loop a 4K video using
Windows’ Movies&TV app, with the
laptop’s display brightness set to 250-260
nits, Wi-Fi set to Airplane mode, and a pair
of earbuds plugged in with volume set to its
midpoint.
Overall, we’d rate the Prestige 14’s run time
as adequate. Don’t blame the hotshot GPU
and CPU; the 4K panel is the most likely culprit.
If you look at the results below, almost
every laptop on the bottom of the list features
a high-resolution display. Battery size matters,
too: While the Dell XPS 15 7590 can produce
better results using a 4K panel, it also has a
massive 97-watt-hour “gas tank.” The
standout battery life numbers come from
laptops with 1080p FHD screens.
The test is “realistic” because if you’re
trying to watch a movie on a train, plane or
automobile, every minute counts. It’s also fair
to say that video playback performance on
any modern laptop is essentially cruise
You have the option of using Intel’s QuickSync,
Nvidia’s NVENC or the CPU cores for encoding.HP Spectre x360 13 2019
