Raspberry Pi 3 out, what’s the difference? A simple comparison chart and some references.

Raspberry Pi 3 is out today (RASPBERRY PI 3 ON SALE NOW AT $35, 29 February 2016), it’s been almost 4 years since I have my first Raspberry Pi, the Raspberry Pi Model B, with has only 256MB ram, now the Raspberry Pi 3 comes with the same price – $35, but much more powerful, including Quad-core 64-bit ARM Cortex A53 clocked at 1.2 GHz, built in 802.11n WiFi and Bluetooth 4.1 LE, and fully compatible with the previous version(s)! No more usb WiFi / Bluetooth dongle from now on also means we don’t need to be worried about the compatible of the WiFi/BT chip and Pi, also save us 2 USB ports, that’s very nice! Let’s take a look at it now:

Here is a photo of Raspberry Pi 3, almost the same look as Pi 2:

To make it easier to be compared, I made a simple comparison chart by myself, to compare the difference between Raspberry Pi 3 and all the Raspberry Pi models I have:

lyrics:

I’ve been here before
But always hit the floor
I’ve spent a lifetime running
And I always get away
But with you I’m feeling something
That makes me want to stay

I’m prepared for this
I never shoot to miss
But I feel like a storm is coming
If I’m gonna make it through the day
Then there’s no more use in running
This is something I gotta face

If I risk it all
Could you break my fall?

How do I live? How do I breathe?
When you’re not here I’m suffocating
I want to feel love, run through my blood
Tell me is this where I give it all up?
For you I have to risk it all
Cause the writing’s on the wall

A million shards of glass
That haunt me from my past
As the stars begin to gather
And the light begins to fade
When all hope begins to shatter
Know that I won’t be afraid

If I risk it all
Could you break my fall?

How do I live? How do I breathe?
When you’re not here I’m suffocating
I want to feel love, run through my blood
Tell me is this where I give it all up?
For you I have to risk it all
Cause the writing’s on the wall

The writing’s on the wall

How do I live? How do I breathe?
When you’re not here I’m suffocating
I want to feel love, run through my blood
Tell me is this where I give it all up?
How do I live? How do I breathe?
When you’re not here I’m suffocating
I want to feel love, run through my blood
Tell me is this where I give it all up?
For you I have to risk it all
Cause the writing’s on the wall
