3. INTRODUCTION
Today’s smartphoneand mobile processors are very powerful, so
powerful that it is almost as powerful as a desktop computer.
Processors are now coming up with more cores. Initially it was Single
core, and then came Dual core; we now have Quad core, Hexa core
and even Octa core. Most processors are 64 bit now as against 32 bit
when it started initially. The processing speed has reached up to 3.0 -
3.5 GHz. The ability to includeGPU (Graphic Processing Unit) inside
mobile processors has enabled devices to churn out the best graphics
picture, 3D capability, Virtual Reality capability and 4k recording.
The improved processor technology also made today’s modern mobile
devices more power efficient. In this article we will learn different
processor used in mobile, tablet, and laptops.
4. MOBILE PROCESSOR
Let’s first see what a mobile processor is. A mobile does not always
mean processor for mobile phones; a mobile processor is found in
mobile computers and cellphones. A CPU chip is designed for
portablecomputers, it is typically housed in a smaller chip package,
but more importantly, in orderto run cooler, it uses lower voltages
than its desktop counterpart and has more sleep mode capability. A
mobile processor can be throttled down to different power levels or
sections of the chip can be turned off entirely when not in use.
Further, the clock frequency may be stepped down under low
processor loads. This stepping down conserves power and prolongs
battery life.
5. HISTORY OF MICROPROCESSOR
The first use of the term "microprocessor" is attributedto Viatron
ComputerSystems describing the custom integrated circuit used in
their System 21 small computersystem announcedin 1968.Intel
introducedthe first commercial microprocessor, the 4-bit Intel 4004 in
1971, followed by its 8-bit microprocessor 8008 in 1972. During the
1960s, computer processors were constructedout of small and
medium-scale ICs each containingfrom tens of transistors to a few
hundred.The first microprocessors emerged in the early 1970s, and
were used for electroniccalculators, using binary-coded decimal
(BCD) arithmetic on 4-bit words. Other embedded uses of 4-bit and 8-
bit microprocessors, such as terminals, printers, various kinds of
automation etc., followed soon after. Affordable 8-bit microprocessors
with 16-bit addressing also led to the first general-purpose
microcomputers from the mid-1970s on.
Since the early 1970s, the increase in capacity of microprocessors has
followed Moore's law; this originally suggested that the numberof
componentsthat can be fitted onto a chip doublesevery year. With
present technology, it is actuallyevery two years, and as such Moore
later changed the period to two years.
Let us see different mobile processors available in today’s market.
6. QUALCOMM SNAPDRAGON
Qualcomm Technologies is a US based company. Qualcomm first
became a known brand when they introduced CDMA technology in
the market. Qualcomm is actively involved in technology related to
semiconductordesigning for mobile devices, tracking devices,
satellite phones, Virtual Reality, wireless charging, communications
etc. Qualcomm is now known for its Snapdragon brand which is
responsiblefor releasing mobile processors and LTE modems.
Snapdragon’sfirst claim to fame in processor market was when it
released the first 1 GHz processor, when the average speed of most
smartphones was only 512 MHz
Qualcomm Snapdragon processors are popularwith all mobile and
tablet manufacturers except Apple.
7. Qualcomm Snapdragon processors are known for its performance.
The processor handlesmultitasking very well and can handleheavy
and intensive processing which is especially good for gaming. The
presence of inbuilt Adreno graphics matches the performance of
processor. Snapdragon processors also produceless heat compared to
otherprocessors. Generally Snapdragon processors are costlier than
otherprocessors.
Starting from 2005, Snapdragon went through a lot of series – S1, S2,
S3, S4, S200, S400, S600, and S800. The processor is going through
S800 series as of 2016 end. S800 series already released S800, S801,
S805, S808, S810, S820, and S821. Most Qualcomm processors in
medium to high end phonemarket is either a S820 or 821.
After 821, Qualcomm released 835 series which was released in early
quarterof 2017. 835 series offer significant changes over 821. The
chip size is 10 nanometercompared to 14 nanometer in S821. The
new processor is 27% faster in performance consume 40% less power
and reduced size by 30%. The new chip is also equipped with Quick
Charge 4.0 which can give enough power to your battery to last a day
with just 5-10 minute charging.
Some of Snapdragon 821 devices are Google Pixel, Google Pixel XL,
Asus Zenfone, OnePlus 3T, Xiaomi Mi 5s, Xiaomi Mi 5s Plus, and
LeEco Le Pro3.
Some of Snapdragon 835 devices are Samsung Galaxy S8, OnePlus
