Official features of the Raspberry Pi model B board according to http://uk.rs-online.com/web/generalDisplay.html?id=raspberrypi:- * Broadcom BCM2835 700MHz# ARM1176JZFS processor with FPU and Videocore 4 GPU * GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode * GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure * 256MB RAM## * Boots from SD card, running the Fedora version of Linux### * 10/100 BaseT Ethernet socket # mine is running a stable 800mhz @ Delta T at 21C of 3C overall without any specialist cooling so these figures are probably 14%++ below what I currently get ## mine has a 4gb "class 4" SD card for the O/S including a standard 100mb swapfile (I haven't seen a need to change that), the SD card is upgradeable to "16gb class 10" ### mine is running Raspbian, the official Raspberry Pi distro with manufacturer-optimised settings |

Last modified: 23 Aug 2012, 1:08:44 UTC Unfortunatelly I don't have Raspberry Pi for testing but I can see that it has been spreading so I think about it. Can you please post some benchmarks of CPU, memory etc? I don't have any idea about its performance. Details provided. Any news? (ODROID-X on order, big 6-page benchmark review available http://www.phoronix.com/scan.php?page=article&item=samsung_odroidx&num=1) |

Assuming its the same sort as the one used by QCN (Quake Catcher Network). They posted the following in the BOINC Dev mailing list on the 8th of August 2012. As you can see they aren't fast but they only cost $35.

Oh, I see. Here are my results ... Number of CPUs: 1 313 floating point MIPS (Whetstone) per CPU 1057 integer MIPS (Dhrystone) per CPU (FWIW I'm running this RPi at 950mhz - on standard voltage BTW - which explains the higher results. It's been going for the past 24hrs, cased with forced ventilation and only a tiny custom-made heatsink on the SOC, running a GUI and a CPU-intensive graphical program. The deltaT across various components is approx +5C which is nice.) |

I've ordered one. They say delivery within 13 weeks. That makes it close to Christmas. @ray, sent you a PM BOINC blog |

Ordered another one from the other supplier and it arrived today. Pity I don't have a micro-USB cable. Arhhhh. I have asked the S@H guys if they are interested in getting multibeam running on it. BOINC blog |

Last modified: 4 Sep 2012, 11:56:34 UTC Ordered another one from the other supplier and it arrived today. The 2nd one I ordered through Element 14. They had them listed as in stock here in Australia, however the cases have a 1 week delay. As for a schematic, I don't think so. It's got surface mounted chips so would be rather complex to make by hand. Besides you'd be hard pressed to do it for $35. Heck if you want one that much I could buy you one over here and post it to you. PM me if you're interested. BOINC blog |

Last modified: 11 Dec 2012, 4:27:35 UTC Wow! Ordered 23 Aug 2012, now 11 Dec 2012. That is far, far too long. If you asked the RPi foundation for a free sample ... I don't think it will ever come. If you bought a retail item ... complain! There are items on Ebay that could be delivered internationally in about 5 days just using a standard Priority postal service like Royal Mail International Signed-For??? FWIW there are around 800K RPi's around. FWIW2 based on my current experience running the new Asteroids@home Windows application on a Gallatin via XP Pro SP3 / non-HT / 50% usage / BOINC 6.12.34 (x86) ... a RPi could take some days running 24/7 to complete just one task. |

Still waiting on my first one to arrive. It's been over 13 weeks now. BOINC blog |
