Now that Samsung has announced its
Galaxy S
III muscle phone, one big question is how its
core technology stacks up against that of its
main Android rival, the HTC One X . So let's take
a look under the hood and see.
The S III packs a 1.4GHz quad-core chip, as the
company indicated last week . Samsung
obviously believes that kind of horsepower is
necessary to drive a 4.8-inch HD Super
AMOLED display with 1,280 x 720 resolution,
among other things.
The One X, with a 4.7-inch screen and an
identical 1,280 x 720 resolution, also sports a
quad-core chip in its European variant -- but
opts for dual-core in the U.S. More on that in a
moment.
Samsung has gone into some detail to explain
why it has gone quad-core for the first time in
the Galaxy S series.
Samsung Galaxy S III (European variant) with
Exynos 4 Quad highlights:
Full-speed video: Uses HD 30 frame per
second video hardware codec engine for
1080p video recording and play-back. Also
includes an embedded image signal
processor interface for a high-quality
camera and an HDMI 1.4 interface.
Speed jump: Owing to its 32-nanometer
tech, the Exynos 4 Quad has "two times
the processing capability over the 45-
[nanometer] process based Exynos dual-
core while consuming 20-percent less
power," Samsung said.
Ready to plug into new phones: Exynos 4
Quad is "pin-to-pin compatible" with the
Exynos 4 Dual, allowing smartphone and
tablet suppliers to adopt the new solution
without additional engineering or design
efforts.
Based on ARM Cortex A9 design: Based
on the current Cortex A9 tech from ARM .
The latest and greatest ARM tech is called
Cortex A15 but those chips won't emerge
as commercial products for a while yet.
Because the Galaxy S III is so new, more in-
depth reviews about performance are on the
way. But the HTC One X is a known quantity.
Let's look at performance and the processor
internals of the European/International
variant.
HTC One X (European variant) with quad-
core Nvidia Tegra 3:
Needless to say, fast: "Blazingly fast -- you
won't feel any Android "lag" when using
this phone," said CNET Reviews. "HTC also
claims a fast camera startup of 0.7 second
and 0.2 second autofocus," CNET said.
"Five" cores: Nvidia calls it "Super 4-
PLUS-1" Quad Core. The fifth processor
core is much more power efficient than the
others and is used -- when performance is
not required -- to boost battery life. "The
single battery-saver core... handles low-
power tasks like active standby, music,"
says Nvidia.
DirectTouch tech: Nvidia DirectTouch is a
patent-pending technology that improves
touch responsiveness and reduces power
consumption by offloading a portion of the
touch processing onto the Tegra 3 chip.
Based on ARM Cortex A9 design: Like the
Samsung quad-core, the Nvidia also uses a
Cortex A9 design. But Nvidia is
undoubtedly working on a next-gen Cortex
A15 chip; Nvidia is very quick at getting
next-gen chips out the door. The Tegra 3 is
manufactured with a 40 nanometer
fabrication process, a slightly older
technology than the 32 nanometer process
used to make the Exynos 4.
Battery life: "Top-shelf components and a
massive 4.7-inch screen take a toll on this
pricey superphone's battery life," said
CNET Reviews.
In the U.S. market, HTE chose to go with a
dual-core Qualcomm S4 processor paired with
LTE in One X. It's not clear yet what Samsung
will opt to do in the U.S., although the specs of
the HTC One X may be instructive.
LTE and dual-core seem to be a good fit
because the Qualcomm S4 squeezes LTE and
the processor onto one piece of silicon. (That's
just not possible with quad-core and LTE at
the moment.) That's quite a feat and
something that Qualcomm has done first. That
level of integration not only allows for more
compact designs but it doesn't compromise
on performance, as many reviews attest to.
