Looking to upgrade to an i7 but want to know what an i7 860 can get PPD

post #1 of 7
Thread Starter 
I have been folding now for approx 18months on GPU's and 4 years on PS3's and am looking at upgrading from a Q6600 to an i7 due the PPD they can obtain.

I have seen figures of 30K-50K PPD for the i7 2600/K and i5 2500/K inc Bonus Points but am having trouble finding what an i7 860 will do at stock and overclocked. If anyone is folding on an i7 860 could you possibly post what ppd you are getting and what speed the cpu is running at. The reason I am asking this is I can get an i7 860 setup used for half the price of the i7 2600. But need its PPD figures to make the correct decision.

Thanks in advance for any info.

my x3440, which is like an i7 860s, is getting 23k ppd on bigadv units, is clocked at 3.6Ghz, and is running SMP on 7 threads.
30k would be done with a higher OC and also run on 8 threads.

What I remember about the i7 860 is that it is not tripple channel capable. I seemed to notice some tpf differences when I went into tripple channel.Half price,that would sell me for sure even if we may at sometime in the future only have -smp work to do (that being the official position not the technical position).What I am getting at is that there is talk of new hardware requirements (in both cpu cores/threads and memory amount) being imposed on bigadv folders.

More data for you:

I'm Folding on four I7 Bloomfield (HT, dual channel memory, Socket 1156) processors - 3 X Xeon X3440s and 1 X 870. Each processor is in its own computer and each computer is simultaneously folding 3 X GPU3 clients. The 870 is clocked at 4.0GHz and the 3440s are at 3.8GHz, on -bigadv work units, here is what I typically produce --

X3440: 23.5K - 25K
870: 24.5K - 26K

Add 1.5K to 3.0K if GPUs are not folding.

Those rates are with the CPUs set to 7 threads (-SMP 7), leaving one thread for the GPU3 clients (all GTS 450 on GPU3). Systems are Windows 7/64 with either 4GB or 8GB of RAM each. I am using the 6.34 SMP client for the CPUs.

EDIT: forgot to mention - those figures above are typical for 6900 work units. Subtract 2-3K for 268X units.

EDIT II: the X3440 is a stunning bang for the buck

Thank you for the info.+Rep to all.

I was considering getting the i7 2600 due to being able to get a used one £50 cheaper than the i7 2600K and probably would not over clock it anyway. But now after seeing the PPD the i7 860 is bringing in I am not sure. As looking around and with the info above. Am I right in thinking both i7 860 and the i7 2600 are going to be very close getting around 20K PPD at stock.

I know the i7 2600K is easier to overclock with having an unlocked multiplier but how easy is it to overclock the i7 2600 non K.

The question another way am I going to get more from an i7 860 which can be overclocked than a i7 2600 non K.
