I went and looked at that passmark benchmark. I see that the i7 970 has a 9930 and the i7 2600k has a 9958, but I just cannot believe that those 8 threads can outperform 12 threads at the same clock speed. Thats what they claim, but I don't buy it. Can anyone post thei i7 2600k scores / results? I may have to build me a new machine that uses that processor to check it out.

Here is my i7 2600k @4.3Ghz running 24/7 for last week:
----------------------------------------http://stats.free-dc.org/stats.php?page=host&proj=bwcg&hostid=1649055 ~5766 points/day Do you have a i7 970 to compare to? ![]() [Edit 1 times, last edit by krakatuk at Sep 27, 2011 6:42:26 PM] |

I have the i7 970. My average points per day is 34,822.

That would be 5766 boinc credits per day (which would actually be 40,362 points. 1 boinc credit equals 7 points) which is where it should be for an i7 2600k running @ 4.3 Ghz. ![]() The 2600k will do 15-20% more work on 25-40% less power(depending on overclock) than a 970.

Ok, probably we are talking in different points.
----------------------------------------Your points are WCG points, my points are Boinc points... If I remember it right, BOINC=WCG/7 34822/7=4974 But you don't say anything about your clock? ![]() |

But you don't say anything about your clock? If you can tell me how to look up my "clock", I will be happy to check it. ![]() Edit: Actually, it looks like my clock is 3.20 GHz if I am reading it correctly. [Edit 1 times, last edit by Former Member at Sep 27, 2011 9:46:59 PM] |

From my host, using 7 day averages from Free-DC in Boinc Points:
----------------------------------------970 #1 @ 4.0GHz = 7,433 970 #2 @ 4.0GHz = 7,445 2600k #1 @ 4.7GHz = 6,308 2600k #2 @ 3.7GHz = 5,009 and also for comparison: 980x #1 @ 4.2GHz = 7,022 (minor stability issues with my current OC) 980x #2 @ 4.2GHz = 8,685 No question the 6 core 970 has more overall processing power for WCG than a 4 core 2600k. If I was building a system from scratch I would recommend the 2600k because the price is lower and they overclock great with little extra work or cooling needed. However if someone wants a nice upgrade from an older 45nm socket 1366 quad i7 then the 970/980/980x/990x or westmere (xeon) chips can be a nice upgrade for more POWER! And with all that said... anyone looking to build or upgrade a crunching rig right now should wait without question! AMD and Intel are both about to release new chips that will be even better than their current offerings :) ![]() [Edit 1 times, last edit by trn-XS at Sep 27, 2011 9:02:15 PM] |

A 980 or above will definitely do more work than a 2600K; this was worked out here in the past (20 to 25% more). So I would not be surprised if a 970 did more work than a 2600 (measuring real performance is always better than going by benchmarks), but comparisons are meaningless without operating system, comparable clocks, HT on/off, task types being run... Even then task length and credit variation makes it a ball park comparison. You might need to go to another Boinc project and run identical task types to get really accurate results, and if you're going to do that then you would need to state RAM speeds, hard drive types and if the CPU's graphical unit was being used or not (SB only).
My i7-2600K @3.8GHz (HT on, all 8threads in use) Win8 did 23K Boinc Credits in 4 days running HCC tasks only. That's 40K WCG Points a day. It had been running for several days before I took these readings. Going by the 970 posts above I would say the 970 does about 20% more work. The thing about overclocking the 1366 systems is that you overclock everything. With the SB you just OC the CPU. Ultimately you are comparing the systems and not the CPU's, but worth noting. Again, the main advantage of the SB is the reduced power consumption. They are not really designed to be high end systems, they just happen to be, relative to previous generations of processor. The high end SB processors will come soon enough, and with a high end price tag to match. Anyway, I see the present 2600's as an alternative to a 920 or similar, but for crunching they are not an alternative to the 6core/12 thread processors. |

just picked up a I7-2600k, 16GBRam, ssd yesterday will start the build today. maybe do a raid5 down the road
