I guess you answered the Odroid posting on the wrong (Raspberry Pi) page:icon_mrgreen:
Nice pictures though, I'll ask the wife to take a snapshot of my 'Pile of Pies' -actually more of a Row of Raspberries, and including the BeagleBone and the still inactive Banana Pro- with her iPad.

Rumour has it that there is a Model 3A+ in the pipeline, as well as a Compute Module 3...
I just found this in my in box, and I thought I better post it for Dirk to review:
It's small, very small:
https://images.stackcommerce.com/ass...hero_image.jpg
Specs:
- Dimensions: 0.98"L x 0.98"W
- Operating system: OpenWrt
- System Memory: 32 MB RAM
- Storage: 8MB SPI Flash (for firmware)
- In-out voltage range: 3.3V to 6V
- Power consumption: 200-220mA
- Processor: Ralink/Mediatek 360 MHz RT5350 MIPS
- Data rate: Up to 150Mbps
- Dual band 802.11n Wi-Fi
- Interfaces include:
- 5-port 10/100M Ethernet switch
- USB
- UART
- Software I2C
- Hardware SPI
- I2S, PCM
- JTAG
- Over 20 GPIO links
But a 360 MHz CPU with 32 MB RAM looks to me only useful as an add-on board to e.g. a Raspberry Pi A+, Pi Zero, BeagleBone Black or Green to expand the limited I/O possibilities of those boards.
Should you buy a Raspberry Pi 3?
The main advantages of the Pi 3 are the build-in WiFi and Bluetooth and the higher Clock- and RAM speed.
The lesser advantages are the 64-bit ARMv8 architecture and instruction set, that unfortunately aren't being used in the present Raspbian builds, partly because the Pi 3 is presently limited to 1GB of RAM because of the used Video Core IV GPU (why don't they give each CPU core its own GPU?).
Basically you have a 64-bit capable CPU on a 32-bit system with 1 GB of DDR2 RAM, like in the olden Athlon 64 days (even with comparable MHz...)
BOINC-wise the Whetstone and Dhrystone MIPS are roughly the same as with the Pi 2, just slightly higher because of the 1200 MHz of the Pi 3 vs 900 MHz of the Pi 2 (1000 MHz when OC-ed). As the Pi 3 downloaded four Asteroids WUs, taking 85+ hours (!) each, I can't go into further detail yet. I've set Asteroids to 'No New Tasks', so in a day or three I can compare the Enigma scores as compared to my Pi 2s. The sole Enigma WU that managed to slip through was finished in a little over 9 hours, comparable to my augmented Pi 2, the one with the extra Hardware Floating Point and Integer libraries.
2nd Enigma Wu went in 5.36 hours, a Raspberry record with me (previously stood at 6 hours).
EDIT: By now the Pi 3 has all the scores in my top-10 of fastest Enigma WUs, so it is safe to say that on average the Pi 3 is the better Pi for Enigma.
EDIT2: It seems that the Pi3 is somewhat more power-hungry than its older brothers. When you've enabled the internal WiFi -one of the boards USPs- it definitely needs 2.5A, preferably 3A or even 3.5A (A as in Ampere). You might see BOINC benchmark MIPs that have a twice as high value when connecting the Pi 3 to a 3A PSU as compared to a 2A PSU:
- 375 vs 711 BOINC Floating Point MIPS (Whetstone) per core
- 1240 vs 2469 BOINC Integer MIPS (Dhrystone) per core
With the new two Goofyx sub-projects that is 12 WUs on a single-core Raspberry, simultaneouslyQuote:
I saw to my astonishment that it was running six different QCN WUs, two Goofyx, a WuProp and an Enigma WU!
That's 10 WUs on a single-core ARM-11 SOC, try and better that! It is a pity the Mexicans have opted out of QCN, otherwise I'd be running twelve WUs now on that poor Pi B+...

That's a beautiful family photo :)
By the way, there' a new VoCore2... still very very small. :)

And the family keeps growing... can it be arranged in a sort of family tree to see each generation and its descendants? :icon_lol:
