Evolution of Smartphone Processors

Evolution of Smartphone Processors

As a mobile engineer, you need to know a bit of background info about them. During the mobile servicing training, you can a detailed analysis of how to work on the latest devices.

Smartphone processors have many claims. IBM introduced a PDA with 8086 adopted for mobiles. Next was Intel with 24MHz i386 CPU, having 32bits.

Qualcomm Snapdragon: It entered with “System on chip” concept and release of the 1Ghz processor. Mobile processors need to control the heat generated. So many of them do not actually work with speeds advertised. Snapdragon generates less heat than its competitors. It has 400,600,800 series for entry-level, mid-range and high-end segments respectively.

Higher Density

S821 line was having 14nm production node, the newer line is with 10nm production node. The newer line also has 40% less size, 27% higher performance.

Apple: Apple used to give designs to Samsung for manufacturing. Now it uses on Package on Package (PoP) along with SOC. A series is the main series used for Apple smartphones.

MediaTek Inc.

This is a Taiwanese company which used to rely on ARM 64-bit Architecture.

They were first to announce Oct Core with SOC. MediaTek produces processors which have better processing and less heat generation.

MediaTek GPU line is in demand and with good RAM boost, you can expect smooth operations.

ARM processors:

ARM provides designs which are used by companies for creating actual processors. The ARM processor lines have been used in Apple, Samsung and other devices earlier.

For mobile phone service training in Kottayam, students are given inputs on all the above-mentioned companies and are well trained to work on the latest processors.

Evolution From Single Core to Multi-Core:

2009 and Earlier:

Cores: The earlier processors were all single core with 32 or 64-bit architecture and 500 Mhz as the standard frequency.

The Architecture was ARMv7 for most of the manufacturing companies. (MediaTek, Apple, Snapdragon) though MediaTek was ahead.

The manufacturing process was earlier having 65nm as a standard production line.

CPU cache size: It was restricted to L2 caches.

 

2009 till 2014

Cores: Most of the companies were able to have a dual core (apple, snapdragon). MediaTek managed to have Quad cores introduced in late 2013. The frequency was around 1 GHz to 1.5 GHz.

Snapdragon introduced 1GHz ahead of other companies.

The Architecture was ARMv8-A for most of the manufacturing companies.  (MediaTek, Apple, Snapdragon) where 2 billion transistors were standard features (at least in Apple).

CPU cache size: Here we see dual-core processors along with CPU cache increasing to L3.

2014 till 2017

Cores: Most of the companies were able to have Quad core, even going for Hexa cores. The frequency was around 1 GHz to 2.9 GHz.

We can find cluster models where 2 cores were having different frequency and rest of the cores at a different frequency.

High-performance cores (in Hexa Core or Quad core) system along with efficient cores were introduced.

The Architecture was ARMv8-A for most of the manufacturing companies. CPU cache size: Here we see dual-core processors along with CPU cache increasing to L4.

So if you are planning to be a mobile phone technician job in Kerala you need to understand the history as well as new developments.

2017 till Now (2019)

Cores: Most of the companies were able to have Hexa-core, even going for octa cores. (apple, snapdragon and MediaTek leading the way). The frequency was around 2 GHz to 3 GHz.

Octa-core is yet to launch fully, but all companies have started the production.

The Architecture was ARMv8.3-A for most of the manufacturing companies.  

Rest of the features remain the same as of now.

For mobile servicing training in Kottayam, it is important to know the latest technologies which are served to the students during the training period at IASE institute.
