Day 1 137.7 FP MIPS/W
----------------------------------------The 1055T 2.8Ghz 6 core 95W edition is sitting at 2996Mhz and using 133W at the socket. It benchmarks with turbo core switched off at 3052 FP MIPS/core (Turbo core won't be kicking in with WCG running on all cores) Now to stand well back and see if it is 24/7 stable Almost 18Ghz from a £150 processor !!  |

I've only lost one day (6 days worth!!) of crunching to "Computation Error" so far
---------------------------------------- took it back from the edge for a while. Still it's reliably chucking out 134.5 Floating Point MIPS per watt at the socket - a 26% improvement in number crunching power efficiency |

 The 1065T with a 95W TDP rating. It is clocked at 2.9GHz, or 3.4GHz with Turbo Core.I've have my 1055T 95W running almost at 3Ghz but the 1065T might have still further head room |

I'm trying to understand, what is more efficient intel's 980X or AMD's 1055T. But I don't believe in the benchmark. Specially when it's screwed up with HT.
----------------------------------------@David Autumns: could you please post, how is the HCC WU runtime on your 1055T and what is the exact power consumtion (W)? @Hypernova: how fast is your HCC WU with HT on and 250W consumption? (I know that 980X is much faster. Question is, if it makes sense to take two 1055T instead of one 980X)  |

You can imagine that there is some dispersion in terms of OC/wattage over the 980X (I have 17 of them running) They are all around 250 watts. If you measure wattage in real-time you will see that you have a few watts regular variation.
----------------------------------------The fastest device at the moment for HCC is Terra and will in average finish one in 1.72 hours elapsed time. This is 103 minutes per WU. The fastest WU's have been around 97 minutes. I wonder how this does compare with other procs.  |

Thanks for the fast answer, Hypernova!
----------------------------------------Funny thing... I have exactly the same runtime on My Q6600@3,4Ghz. That means, one your HT Core is as fast as my real core. You have 12 HT cores, I have 4. Your device is 3 times faster than mine while consuming same power (250W). That's why I'm thinking about an upgrade now  |

krakatuk, I think the X58 platform with 1366 socket was not a bad investment. I took this standard a year ago and Intel confirmed that this platform stays until 2012. You will also have the I7 990X (a little faster in stock speed 3.46 Ghz) released soon. It will not be more expensive than the 980X and some tests have shown that it is a little better than the 980X in terms of consumption or core temps. This means it could run well OCed at 4.2 Ghz continuous.
----------------------------------------I admit this makes it for an expensive platform but it should give you an unbeatable 55 kppd on WCG. In terms of $ invested per point or per WU or per hour runtime over say three years of crunching, nothing can beat it today in my point of view.

----------------------------------------I'm getting on average 20556 WCG points/day on my 6 Core (all real ) 1055T Box overclocked to 2.99Ghz a core The complete box, without my Monitor, consumes 137W/hour at the socket 980X £728.49 1055T 95W TDP edition £162.14 and the motherboards are 2/3rd the price Get 2 1055T systems and if you are are careful you won't use any more electricity and you can still pocket the cash you would have spent on the 980X and have a really good night out instead I've just negotiated a new deal with my electricity supplier First 728KWh per year £0.1848 inc VAT Unit rate after 728KWh £0.1151 inc VAT Night Rate Midnight until 7am £0.0457 inc VAT All prices GBP - so you see why we need absolute efficiency in the UK those are the cheap prices !!!! Assuming I've spent my expensive KWh's having a shower in the morning 31.2p/day or 659 points per penny nothing can beat it today in my point of view Just fighting the AMD corner Hypernova - you know I have to Enjoy the crunching krakatuk we're all making a difference Dave |
