Chipset 2016: The Most Popular Chipsets For Wi-Fi Tablet

To get updates and news about Hardware Development it's HERE


Back in December 2015 I brought you the first of our chipset reviews that looked at some of the more popular chipsets being used in non telecom (wi-fi) tablets.


With the electronics industry being as fast paced as it is, a lot can change in 10 months which is why for the next few months you will find updated reviews with some more options that have become available or that have become more popular.


In December I reviewed:

  • Allwinner’s A33
  • Rockchip’s RK3126 and 3128
  • MediaTek’s MT8127
  • Intel’s Z8300


Of these chipsets the RK3128 and MT8127 have stopped production. The Z3735 from Intel which was expected to stop production last January (as mentioned in the previous article) has been continued and is still a popular choice.


Below is a table comparing 5 other wifi tablet chipsets.

Types of RAM



RAM (Random Access Memory) is where information from your device is processed and manipulated. The RAM is like the middleman between the storage (ROM) and the processing cores.


The type of RAM in your tablet makes a difference on product usability as it has an impact on the performance speed and power consumption of the device.


There are many different types of RAM. You can see some of the different types in the ‘Memory Interface’ row in the table above. So what do the these terms mean?


DDR2: Double data rate 2nd generation

DDR3: Double data rate 3rd generation

DDR3L: Double data rate 3rd generation low voltage

LPDDR3: Low power double data rate 3nd generation


DDR became obsolete a while back and DDR2 is also heading that way as technology adopts new ways to achieve faster speeds/data rates for RAM memories.


DDR3 technology picks up where DDR2 left off bringing the speed up to 1.6Gbps from 800 Mbps bandwidth (DDR2). DDR3 is still rather large and is more commonly used in desktops. It operates at 1.5V and consumes more power and produces more heat than DDR3L. DDR3L operates at 1.35v.


The most common type of RAM in tablets in LPDDR3. This produces less power and heat again than DDR3L and operates at 1.2v. Below is a comparison table between DDR3, DDR3L and LPDDR3. (Table Source: Synopsys)

At the moment LPDDR4 is only really being used by the newer higher end chipsets that are more commonly available to the big brands but will become more popular with all models in time.


This video shows a visual performance comparison between LPDDR2, LPDDR3 and LPDDR4.



MediaTek MT8163

With MediaTek more focused on smartphone and telecom tablet IC’s they don’t have as many options for a wifi only tablet IC.

The MT8163 is an entry level IC that can be found in Acer’s Iconia One 10 tablet.


RockChip

RK3188

This IC can support a relatively high resolution screen (2048x1536 pixels) for a chipset that is marketed for use in entry level tablets. If you require a device with a high screen resolution but the other requirements are fairly basic this chipset could be a suitable option.

It can be found in the Pipo M7 pro tablet.


RK3288

RockChip RK3288

Rockchips 3288 chipset is used in medium to high end tablets, notebooks, smart monitors and is a very popular choice in 4kx2k TV-Boxes.


While this chipset is mostly used in TV-Boxes due to its ability to support 4kx2k resolution it is still an option for tablets that with a focus on Ultra HD screen resolution.

This IC can be found in the Pipo P9 tablet.


Allwinner

A64

The A64 IC was introduced during the summer of 2015. This chipsets boast a sub-10 seconds system boot, 4K HDMI output and H.265/HEVC 4k video decoding in the hardware.

This chipset offers a low price option for a 64 bit tablet processor based on ARM Cortex-A53.


A83T

The A83T was designed to be a high performance but extremely power-efficient octa-core processor. This is why it packs eight energy-efficient Cortex-A7 cores that can run simultaneously at around 2.0GHz.


The InFocus C2107 uses the A83T, you can see a video review of that tablet here.


Hatch has relationships with all the IC companies mentioned in this article and can support projects based around any of them.
