Samsung Galaxy Tab Review - Android takes on the iPad
Introduction and Hardware Overview
saw the first releases of what can be considered a truely modern tablet
computer. Instead of the old haphazard notebook computers turned tablet
with resistive touch screens, we saw something new. Embedded systems
with with capacitive, multi touch capable displays have invogorated the
market for tablet computers. The forerunner of this new market segment
by far is Apple’s iPad. However, some people are not satisfied with
Apple’s closed platform in iOS, bringing on other competitors, such as
the Samsung Galaxy Tab, with the Android OS.
radical difference in the iPad hardware versus the Galaxy Tab is the
adoption of a 7”, 1024 x 600 LCD display instead of a 10” one. In my
experiences, this provides a solution that is much easier to travel with
and carry in many different situations, while not losing any real
usability features of the 10” iPad.
a bigger screen size, hardware in the Galaxy Tab is extremely similar
to the Samsung Galaxy S series of phones. Both the Galaxy S and Galaxy
Tab feature the Hummingbird processor core, developed by fabless
semiconductor company, Intrinisty. This is an interesting detail, as the
Apple A4 processor, first introduced in the iPad, and the Hummingbird
core were both developed by by the same company, and are similar.
However, since the development of this chip, Apple has purchased
SoC unit used on the Samsung Galaxy devices consists of a Hummingbird
processor core, based on the ARM Cortex A8 processor, paired with a
PowerVR SGX540 GPU. Both the ARM A8 Core, and the PowerVR GPU are tuned
to give maximum processing and video rendering capability. In
particular, the PowerVR GPU (found in the Hummingbird and TI OMAP SoCs)
greatly outperforms the standard Qualcomm Adreno 200 GPU in our
benchmarks, but more on that to come.
Comparison of the Galaxy Tab to the Droid X, Epic 4G, and Droid Incredible (left to right)
the Galaxy Tab has a very minimalistic design. On the front of the
device, all we see is a solid glass screen, with the 4 standard Android
menu buttons represented in a touch sensitive form, and a front facing,
