SPECS
The headlining feature of the Pi 3 is the built-in WiFi and Bluetooth, but it doesn’t stop there. Here’s the complete specs for the Pi 3:

SoC: Broadcom BCM2837 (roughly 50% faster than the Pi 2)
CPU: 1.2 GHZ quad-core ARM Cortex A53 (ARMv8 Instruction Set)
GPU: Broadcom VideoCore IV @ 400 MHz
Memory: 1 GB LPDDR2-900 SDRAM
USB ports: 4
Network: 10/100 MBPS Ethernet, 802.11n Wireless LAN, Bluetooth 4.0

Its available, at least, at RS component ( 18 000 in stock ). Just ordered 2.

Still Sata is missing which IMHO is a pity because an SSD combined with a Linux board like this would make a very snappy computer.

Ordered one from RS.
It's a bit disappointing that the Ethernet still is USB. At least WiFi+BLE is connected via SDIO and not USB, which should give better latency (most probably WiFi will now be lower latency than Ethernet

).

But as it seems, there is no software available for it at the moment

As I read it Raspbian doesn't have the necessary drivers and no 64-bit environment. You can still roll your own Linux/Debian/whatever which includes the drivers.

The just updated Raspbian image (32 bit only, though) has all the drivers.

There's tons of similar boards (Banana Pi, Odroid, Cubieboard etc.), some of them have SATA.

with only 1GB ram what would be the big point of going 64bit?

How many have a 5 million units base of users ?

No big point but some performance improvements.
In AArch64 mode you have access to 64bit wide general purpose registers.

# of users probably matters a lot less than # of competent OS developers. Unfortunately, it seems like many of the inexpensive platforms with better high-speed IO than the RPi don't have enough of a developer base to get things into shape in the first place, and keep up with major OS updates.

I'm a Raspberry Pi noob, would it make sense to start with this version? I assume there's no point in getting the older one, but what about the smaller board that was also announced? It seems limited, so I'm leaning towards the Pi 3. Thanks in advance.

Gmetal · « **Reply #12 on:** March 01, 2016, 08:31:20 am »

I bought a Pi 2, and playing around with it for IOT type projects, and had to purchase 2 separate bluetooth (non LE) and Wifi modules, which were a pain to get going in my case for some reason, losing 2 USB ports. Including them on board is a fantastic desicion, I honestly would have paid a 15$ premium for that feature.

Definitely. Pretty much the best model. There is a cheap 'pi zero' model, but that is probably best once youve worked out a precise use that you have prototyped with your fully featured Pi and leave that in place in a project etc.

Excellent! Thanks Gmetal!

funny was friday first rumors and on monday i got adverts from pollin in my postbox announcing it, nearly apple level

just ordered 2 to play with for my cnc controller project the extra power should come handy...

Conan117117 · « **Reply #15 on:** March 01, 2016, 11:37:02 pm »

Is there any performance/hands-on test results available for the new Pi? I remember Pi 2 having the flash reset issue

I ordered from MCM but they aren't shipping yet.

It other news, its quite a power hog

Is it really that hot??? What exactly is it running to get so hot? I think it needs a heat sink...

Howardlong · « **Reply #19 on:** March 02, 2016, 06:15:08 am »

I ordered two from RS in the Uk on Monday expecting out of stock, but they arrived yesterday. Haven't plugged them in yet, not sure how long they'll be gathering dust in a drawer with the other ones before I get around to using them

actually there is no point in getting this one, you should wait for Pi 5 at least ...

I just tested mine today. With the additional wifi, they are a joy to use, without fiddling with pesky wifi dongle
( for my previous pi, I had two of them : one which never worked, and the other one (most expensive, around 10$)
which worked).

I had already a Pi camera, and I could set up a streaming video using vlc in no time.
I dont thing any thing can beat it for this application in term of perf/price.

I hope this time it's available before 6 months, the release of the pi zero was a disaster....

MobileWill · « **Reply #23 on:** March 07, 2016, 09:25:03 pm »

Adafruit has them in stock as of today.

One of the great benefits of the Raspberry Pi family is the inclusion of Wolfram's Mathematica. Since its release in 2014 it has evolved from version 9 through to 10.3. I have used the Mathematica benchmarking suite to compare its speed on the three broadcom iterations of the Pi's SOC (BCM2835 1GHz, BCM2836 900MHz, BCM2837 1.2GHz) on board the Pi Zero, Pi 2 and Pi 3 respectively.
For the test, I used the same microSD card across all three models running headless (Distro:Raspian Jessie; Mathematica: 10.3.1):

Raspberry Pi Zero	2113.1 s
Raspberry Pi 2	1250.3 s
Raspberry Pi 3	461.361 s

The Full benchmarking results are in the attached .xls file, which also includes the results for an original Pi B with Mathematica 10.0.2. The reason the tests were repeated five times was simply that I could not believe that the latter ran the "Matrix Multiplication" faster than the latest, greatest model

.

Furthermore, comparing these results with those determined by Matt Andereth (Pi B with Mathematica 9) shows how much more usable this software has become in only two years.
