Thanks kateiacy, that's an excellent Wattage - most dual core Atom systems use way more than that. The Intel-Ion systems use around 50W when in full use, not inluding the monitor.

Some more power consumption numbers for AMD Zacate: Lower than Ion all over the board.

Sorry to resurrect an old thread but I have a newbie question.
As mentioned before, I am going to build a new computer soon (probably in the next 3 weeks) and I am choosing a processor for crunching. Orginally, I was planning on using the AMD Phenom II 1090/1100 as it was a fast 6 core processor. However, I was at my cousins and he agreed to run wcg for me on his rig which has an intel i7 950 which with hyperthreading processes 8 tasks at a time. My question is which is better? The 6 core processor or a 4 core hyperthreading. If it is the 4 core, then I would base my system around that. |

Hi,
----------------------------------------the appropriate answer could be: how much are you willing to pay for your system ? Based on the ratio power/$, the Phenom II x6 will be surely the best choice (e.g. together with an ASUS M4A88TD-M EVO/USB3 motherboard). If you are looking for pure power (without any consideration on price), the i7 is maybe a better choice but it is warm (and noisy) and HT is not exactly bringing a double of performance (it is less than factor 2). If you plan to crunch for CEP2, HT is potentially not really an advantage. As already mentioned, because of a affordable price/performance ratio and because of a reliable CPU-upgrade path (thanks AM3-socket), I am very satisfied with the Phenom II x6 performance. Cheers, Yves |

WRT Performance, you should consider purchase price and Running cost.
In industry a standard procedure is to look at purchase + running costs for 2years per performance. While this is very generic and not specific enough for many home users it's at least a better starting point than speculation. pirogue created a program to produce real analytical results. You can use this to calculate real world numbers. If you post up your i7, PIIx6 and SB results it would be useful to others currently interested in a system. The 32nm Sandy Bridge processors are probably the current best CPU's for crunching in terms of CPU/system purchase price vs performance, but they are more expensive than their AMD competitors, so it's not a clear situation; it's down to what you want to spend. Within 6months there will be many faster CPU's than the Phenom II X6 and SB; the Bulldozer range will be released and the big-brother SB CPUs will start to hit the shelves. These will probably outperform present processors by about 50% possibly more when it comes to crunching. |

The 6 core processor or a 4 core hyperthreading. If it is the 4 core, then I would base my system around that. First, is this computer to be used for other functions or strictly WCG? If for home use, you should check what software you will be using to see if it will use all cores or just a few. Next, money you want to invest. You would want to get the most bang for your hard earned bucks and want it to last a few years. Hyperthreading only adds about 30% performance. But as stated earlier, if you can wait a little, more chips are coming soon, which drive older ones lower. AMD chips are less expensive for them to compete. Hopefully bulldozer evens the playing field for performance with intel. Suggest you lay out your budget, then start comparing processors. Sandy bridge is less power consumption and if you get a motherboard with UEFI bios, very simple to over clock with supplied software. Good luck and let us know what you built.
Crunching for humanity since 2007!

Is any of your AMD 1055T processors overclaiming BOINC credit points for the WCG WUs crunched by those processors? |

nanoprobe: Is any of your AMD 1055T processors overclaiming BOINC credit points for the WCG WUs crunched by those processors? Not really. Most of the time I get less points granted then claimed because I'm running Linux and it crunches faster than windows for less points. The only time I get a swing the other way is if my wingman is way slower or slightly faster. Even then it's usually only a few points.

Fred De Condappa, Ballswinger:
----------------------------------------If you're looking for the most bang for your buck at a lower priceLevel, AMD-Linux platform is the way to go. If you are looking for the most bang/bells/whistles that money can buy, then the Intel-Windows platform is the right ticket. How well each platform pays off in terms of BOINC credit is another matter altogether. My observation tells me that an AMD-Linux machine is almost always deemed as overclaiming else gets a low granted BOINC credit compared to their Intel-Windows counterparts. In effect, the valuation system tends to favor the Intel-Windows platform else disfavors or does not extend the same courtesy to the AMD-Linux platform. nanoprobe: Most of the time I get less points granted than claimed because I'm running Linux and it crunches faster than windows for less points. You should get more points for doing a WU in less time and the fact that you don't indicates a possible distortion in the valuation system.------------------------------------ Edit1: 2011.04.13We.1720.UTC Edit2: 2011.04.13We.1852.UTC [Edit 2 times, last edit by Former Member at Apr 13, 2011 6:52:26 PM] |

In effect, the valuation system tends to favor the Intel-Windows platform else disfavors or does not extend the same courtesy to the AMD-Linux platform. Well, here it is the other way round. AMD platform Phenom 9650 almost always gets more granted than claiming (5-20%), and as a core i5-760 gets way less than claimed - also in the 5-20% range. Both have 4 cores, both running Ubuntu 10.4 64-bit. |
