A bit better specs than the Raspberry Pi3, but also a few dollars more and a smaller userbase. I might be interesting to play with it for a few bucks . [edit2] Just noticed you can order from a shop in Germany, that is much better than my order for the Odroid-U2. I ordered the Odroid-U2 from their website and it took a long time before it arrived. I also had to pay import taxes, which UPS charged me a hefty 20 euros handeling fee for. That looks much better for us than the raspberry pi.  2016-03-13, 23:52 #112 Xyzzy "Mike" Aug 2002 22·72·41 Posts 2016-03-17, 03:14 #113 Xyzzy "Mike" Aug 2002 803610 Posts http://arstechnica.com/gadgets/2016/...n-may-for-650/ Quote:  The new NUC6i7KYK, codenamed "Skull Canyon," includes a 2.6GHz (3.5GHz Turbo) 45W quad-core Core i7-6770HQ—not the fastest Skylake laptop chip that Intel can sell you, but definitely one of the fastest. 2016-03-17, 05:15 #114 ldesnogu Jan 2008 France 10000111112 Posts AnandTech concluded this about the NUC6i5SYK: http://www.anandtech.com/show/10121/...ucff-pc-review Quote:  Overall, our experience with the NUC6i5SYK was not what we have come to expect from a typical Intel product. Unless one wants to be an adventurous beta tester, we would suggest waiting for Intel to resolve all pending issues with the Skylake NUC before contemplating a purchase. Hopefully, the Iris Pro-equipped Skull Canyon NUC (with Thunderbolt 3 integrated) will fare better when it comes to the market. 2016-04-12, 15:50 #115 fivemack (loop (#_fork)) Feb 2006 Cambridge, England 13·491 Posts Quote:  Originally Posted by VictordeHolland Hardkernel Odroid-C2 released http://www.hardkernel.com/main/produ...=G145457216438$40 (probably excluding shipping)
I've got one of these on the way from the German retailer; should arrive end of the month. At which point I have a stable of five machines with five recent ARM architectures (Cortex-A7 RPi2, Cortex-A9 ODroid-X, Cortex-A15 Jetson TK1, Cortex-A53 ODroid-C2, Cortex-A57 Jetson TX1) and should start working out some more sensible way to store, network and use them.

Running four threads of gmp-ecm is not enough to make the fan turn.
Now that 64-bit is available, did you retry?

 2016-06-23, 14:39 #118 fivemack (loop (#_fork))     Feb 2006 Cambridge, England 13·491 Posts I have a weekend of 64-bit ARM Linux planned (Raspberry Pi 3 has arrived at the office for a slightly different experiment, TX1 and Odroid-C2 are at home). Just hoping that being repeatedly walked on by the cat while turned off is not bad for devboards.

Cool, can't wait to see what you find!

I really need to get my hands on a proper 64-bit platform that would be both easily hackable and not too pricey. TX1 is too expensive and I want something more powerful than A53 to play with.

Use a hair dryer to remove cat hairs before turning them on

 2016-08-04, 18:09 #121 xilman Bamboozled!     "𒉺𒌌𒇷𒆷𒀭" May 2003 Down not across 29×367 Posts The Raspberry Pi Zero is very small, dirt cheap and takes hardly any power, so I'm thinking about building an ECM engine from a bunch of them. Does anyone here have a Pi Zero and would be willing to benchmark GMP-ECM on it? Buying a fully functional one (i.e. with PSU and storage) for myself would cost less than a gallon of beer but I'd like to avoid the latency if possible. Also considering the Pi-3 if its price/performance is better than the Zero. At http://cpc.farnell.com/mksp2-raspber...s-and-noobs-os the Pi-3 is £31.19, or £38.72 with storage included. https://www.alibaba.com/product-deta...857.0.0.BbCy3v offers the Pi Zero at \$1.30, which is about £2 after import duty and VAT. An 8G SD card is available for less than £3. Does a Pi 3 offer at least 38.72 / (2+3) ~ 8 times the performance of a Pi Zero?
