MARCH 2021 PCWorld 57PERFORMANCE
The Porsche Design Acer Book RS looks sleek
on the outside, but wait until you see what’s
under the hood. We’re talking smooth
single-core performance, scorchingly fast
multicore speeds, quick starts out of the gate,
and impressive graphics performance for
content creators. Oh, and the Porsche’s
battery mileage is surprisingly good, too.
PCMARK 8 WORK 2.0
PROFESSIONAL
First comes our standard PCMark 8 Work 2.0
benchmark, which measures how a laptop
handles day-to-day tasks such as web
browsing, word processing, tinkering in
spreadsheets, social networking, online
shopping, and video chat. Because all of the
tasks simulated in PCMark 8 demand only a
single processor core, laptops with quad-
core or better CPUs won’t necessarily have an
advantage over dual-core systems. Any score
over 2,000 means you can expect butter-
smooth Office performance.
Unsurprisingly, the Porsche Design Acer
Book RS aces the PCMark 8 benchmark, landing
in the top three and clearing our 2,000 standard
by a mile. Of course, all the laptops in our
roundup handled PCMark 8 without breaking a
sweat, including the Lenovo Yoga C640 and its
humble dual-core Comet Lake CPU.HANDBRAKE
Our next benchmark is much more of a
challenge. Using the free HandBrake video
encoding tool, we convert a 30GB MKV file
into a format suitable for Android tablets, a
lengthy (often an hour-plus) and CPU-
intensive task that never fails to turn up the
heat. Because video encoding requires
multiple processor cores, our HandBrake test
favors laptops with more cores.
And vroom! The Porsche Design Acer
Book RS absolutely crushes it with HandBrake,
easily outpacing two laptops with more
powerful Core i7 Tiger Lake processors, the
Acer Swift 5 and Dell XPS 13. It also made
mincemeat of several Comet Lake and Ice Lake
systems, while more than halving the score of
that dual-core Lenovo Yoga C640 (remember,The Porsche Design Acer Book RS turns in a rock-
solid PCMark 8 performance, so don’t expect
any Office hiccups.
