Inside the Samsung
Galaxy S III: Quad-core drives galaxial screen
The Samsung Galaxy S
III is a big phone with a burly chip to match.

The Samsung's Galaxy S III's vast 4.8-inch screen sits atop a
quad-core processor and Sony camera, among other goodies exposed in detail via
a chipworks teardown.
Before we dive into the specs, let's be clear. For a phone, it's
big. Big enough to be brushing up against 5-inch mini tablets.
"I'd say it does
verge on being unnecessarily large, but thankfully it isn't as ludicrously big
as the Samsung Galaxy Note with its 5.3-inch screen," said
CNET"s Jessica Dolcourt in her review of the phone.
And note this is the
global version of the phone, not the LTE version that has yet to arrive in
the U.S. The LTE-based U.S. version could opt for a dual-core Qualcomm chip
that integrates the LTE function. We'll have to wait and see, though.

Nitty-gritty specs:
·
Processor: Samsung Exynos 4412 quad-core A9 processor with 1GB DDR2
memory. The quad-core Samsung chip was only announced in
April. So, this is the first chance for Samsung to strut its quad-core stuff.
Owing to its 32-nanometer tech, the Exynos 4 Quad has "two times the
processing capability over the 45-[nanometer] process based Exynos...Dual while
consuming 20 percent less power," Samsung said in April.
·
Camera: the
8MP camera sensor is a Sony back-illuminated sensor (BSI)
unit. Essentially the same camera found in the iPhone 4S.
"Folks can finally compare Apples to Androids when it comes to picture
quality," said iFixit, which provided commentary to the chipworks
teardown. And the other camera? At 1.9MP, it "should vastly outperform the
VGA unit on the iPhone 4S,"
according to iFixit.
·
Battery: The
2100 mAh battery is big when compared with the iPhone 4S' 1420 mAh and Galaxy
Nexus' 1750 mAh units. The battery incorporates the Near Field Communications
(NFC) module used in "S Beam."
·
Glass: One
of the first phones to tap Corning Gorilla Glass 2.
Corning says it is up to 20 percent thinner, enabling slimmer devices and
better touch responsiveness and brighter images but with the same "damage
resistance" as before.
·
Display: iFixit
makes a good point. At a resolution of 1280x720 the display packs almost as
many pixels into a 4.8-inch screen as some laptops have in a 13-inch screen.
·
Other silicon highlights: Samsung NAND flash; Intel Wireless
PMB9811X Gold Baseband processor; Murata WiFi Module; Broadcom BCM47511 Global
Navigation Satellite System (GNSS) receiver.
