Tablet PC A31 Based CPU.


Allwinner is a CPU manufacturer.

I am happen to post that my first Onda V972 just arrived today.

It was more time consuming removing and replacing the default apps to English than anything else. But the 2 hours of exploring did allow me ot really see what the tablet was all about.

The A31 based CPU really shines.

This is my first tablet so I'm comparing it to my workstation and servers which is a bit different than tablet to tablet.

Basically I wasn't going to spend a dime on a tablet until it was up to i3 or better in responsive touch. I do believe this is the level of processor we all need in tablets.

What I hope to do here is to compare and find all Tablets that will be using the Cortex-A7 CPU model. 

The bullet point list above shows the copy listed in

ARM  is ARM Holding which is the company that developed the platform used.

Let's get to the details we are looking for and follow along with my not so popular rules.

1. For everything you can not do on your tablet make sure you can do on a remote desktop.

Who came first in this Quad-core world is not important with me. (MediaTek

What is important is who is going to run the best configurations and best in hardware.


Have you seen the video marketing and products from Qualcomm?
It's tough, but it's going to boil down to price that's about it.
Let's say if you had a CPU that was made of gold and one of silver and both ran the same OS would you pay in Gold or Silver?
Ok, next let's look at the MediaTek MT6589... Didn't really find what I was looking for. I'm sure not only big name brands use this chip.
What makes fast better? Fast Channel Memory, Fast Graphics and Cores that run as they should.
