The atom c2750 cpu has piqued my interest by being such low power but seemingly on a par overall with q6600 for performance maybe.
----------------------------------------I am curious to hear from anyone who has used one of these on WCG and is prepared to give some numbers.  [Edit 1 times, last edit by OldChap at Oct 7, 2014 6:19:04 PM] |

this thread should me merged with that one of the most efficient CPU... ;)

As far as efficiency goes the C2750 isn't exceptional according to the CPUmark/TDP chart:
http://www.cpubenchmark.net/power_performance.html It fares better in this comparison: http://robpartridge.blogspot.com/2014/04/inte...-overview-comparison.html As far as I can tell my Z3740 is basically 1/2 of a C2750. I calculate it would be about 3 times as powerful as my Z3740. The C2750 uses 5 times the electricity however. |

Thanks for those enels.
----------------------------------------Finding the happy balance between running cost and points and between purchase price and savings on running cost with an eye on points is not a simple thing. I think that due to the oddities of the points system here the only way I shall get the answers I would like will be to buy and run one of these. |

You're welcome OldChap,
I agree finding a happy balance is not simple. I don't even have a good rule of thumb for myself. If you decide on an Avotron C2750 there are a couple things you probably know, but I'll mention. I saw a review (which I can't find now) that showed 1.5V memory used about 1 watt more than 1.35V per 8 GB. I don't think it has AVX. |

The hardest thing to match to a build like this is a PSU. I read somewhere that, running prime95, the system power draw was ~30w with one type of psu and 40w with another
----------------------------------------Shame, I cannot afford to run 8 at once on one psu  |

No idea what this was about, avoton or avotron, went to look and hit on this: http://wccftech.com/intel-avaton-atom-octa-core-soc/
----------------------------------------Could/would/should be the path for large computing with low power, considering cost of installation/maintenance in large datacenters is mostly still matched by cost of power. If only the android app was stable enough for general deployment and the agent was tuned to not drain battery when charger can't keep up, reduce computing cores automatically so it can. That platform could be huge. Sorry for the tangential Postscript, the funny is the author in the linked article gets it about 18 times wrong occurding the wordcounnter, where the slides show 'avoton', and he keeps posting and heading 'avaton'. Really like 6 watt tdp. [Edit 1 times, last edit by Former Member at Oct 12, 2014 3:05:21 PM] |

No problem.
----------------------------------------The basic premise of this investigation is based on my previous jump from a single 377-0K setup overclocked to reach 7500 ppd to that of a dual cpu rig that can get 14-18Kppd using less power total cost of ownership over 3 years here where I live would be in the order of: GBP7903 for the 3770K (overclocked) which should achieve maybe 38M pts Boinc from 40 threads which would be ~4850pts per GBP. GBP4780 for dual E5-2580v2's which should achieve maybe 33M pts Boinc from 40 threads which would be ~6870pts per GBP. Based on the above figures then using the same number of threads on c2750 and making the assumption that a single cpu can achieve 3500 boinc per day then GBP2770 for 5*c2750's which should achieve maybe 20M pts Boinc from 40 threads which would be ~7420pts per GBP. There are a number of assumptions made here but it is shown to take into consideration the moderately high cost of electricity here where I live. For those living in areas where the electricity cost is lower there will be a totally different result. where the power costs 7 cents the following points per dollar might be closer: 8,836.27 8,732.23 9,094.84 This clearly shows the influence of electricity cost and how in places like California and Germany careful selection of hardware could help matters greatly. |
