There must be a thread about this somewhere, but I've not found it, so...
----------------------------------------What sort of computing power does an average Android device bring compared to an average PC? I know there is a whole range of different hardware running Android, so it's a hard question to answer. But even in very broad terms - are we talking about a smartphone bringing a small fraction of a traditional CPU's horsepower? Has anyone done any stats on this?

Look just a little bit harder ;>) The 'average' last 30 day active Android device brings about 21 credit per day. http://bit.ly/WCGAndroid
Android is to me a hook-line-sinker vehicle, not core crunching. |

Thanks (apologies, this probably wasn't really a support question, either). I'm up and running on an Android device, but I'll keep my main focus on the desktop/server cores I think.

My computer (6 Core + HT) has generated 1,833,615 points in ~402 days that equals ~4,500 pts/day or 375 pts/day per core.
----------------------------------------My android device (4 Core) has generated 69,568 points in ~95 days that equals ~700 pts/day or 175 pts/day per core. Not too bad at all. Another difference is the clockspeed. The computer runs 3,5 GHz and the Android runs on 1,0 Ghz. Lets have a look on the power consumption: Computer 180 w/h and Android 7w/h  [Edit 1 times, last edit by Eric_Kaiser at Nov 26, 2013 8:35:59 AM] |

Expressing Eric's numbers differently:
computer = 1040 points per kwh android = 4166 points per kwh |

Still you need to have a pile of Android devices to match one 6 core HT. How much would those cost, not to speak of the initial CO2 footprint.
If not already, when Eric would run his comp on Linux-64 [Android=Linux] he'd increase VINA throughput by about 60-70%. |

In my case: The computer I've built cost 2.400€ (i7-3930, 64 GB RAM, 2x256 SSD, 4TB HD, Radeon 7850). The android device cost 130€ (but this was an expensive one: Neo X7).
----------------------------------------In Germany electrical power is expensive: 0,29€/KWh (green energy). That means with 1 KWh the android runs nearly 6 days 24/7 and my computer only 5,5 hrs. I tried to increase crunching output by opening the android device an placing a fan on the mount cpu cooler. But it doesn't prevent the throtteling of the cpu. Perhaps after warranty I replace the cooler on the android device. Hopefully the cpu will run with 1,6 GHz instead of 1,0 GHz. Edit: Linux Currently I haven't found a solution to run this device with linux. I must admit that I'm a linux noob. [Edit 2 times, last edit by Eric_Kaiser at Nov 26, 2013 12:17:13 PM] |

Ubuntu is so childs-play... download image,http://www.ubuntu.com/download/desktop
burn to DVD or to USB stick, boot from it, run it in trial [without installing], see the Try Ubuntu before you Install section, pick BOINC from the Ubuntu Software Centre once up and run with it for a while [all memory resident] Now running 13.10 with Cinnamon GUI interface on top > 99.2% efficiency when idle. When GUI is unloaded, only terminal, 99.8% efficiency [FA@H,SN2S and MCM] |

Now I got it Rob. You mean linux on my computer.
----------------------------------------Thank you very much for your explanations. Nope. I can't run it with linux. Crunching is not the main purpose of this computer. For the main purpose it must run windows. I spend the resources to boinc when not in use or full power is not required otherwise.

There's now a BOINC with VBOX included for Windows http://boinc.berkeley.edu/dl/boinc_7.2.33_windows_x86_64_vbox.exe [84MB package]. Not read up, no experience at all, but this could set up a VM with Linux running in it. I'm considering for my Octo "must run W7-64+Office13". The idea to keep 2 cores for W7 and 6 set aside to a Linux-VM has substantial appeal to me.
