*ADMINS, I think this chart should star in some important palce as I've never seen one before at the Community-maintained FAQs. Thank you.
----------------------------------------------------------------------------------------------------------------------- I made a CPU power comparison in computers under my command. Results:- Overclocking makes no difference - Big L2 Cache on your CPU makes all the difference - Intel new i7 CPUs are crunching beasts since with their Hyper Threading technology they process 8 tasks in any given minute. Comparison chart: Here is how I managed to see the scores. (The Q9450 at stock speed is running only half a day, sio it's similar to the overclocked Q9450): *Please replace your images with appropriate size. tks**tkh

Hi Alex,
----------------------------------------May i ask you to shrink you image a bit. Many do not have very wide screens to view this. As for the information, results is a debateble measure because the continuous flex of job durations. Credit or points per day would add to the "feel" of the numbers. Many refer to RAC (Recent Average Credit) as a measure of performance. good going and cheers

Regarding the picture, right click on any image>properties>copy the links>paste into browser.
----------------------------------------You'll get this: http://img134.imageshack.us/img134/4954/wcgsurveyji9.jpg Regarding the results: You are right, resaults DO vary each day. that's why all my results based on average of a few months. Like if Q9450 did 20 or 10 a day, I wouldn't count it at all. only, the mainstream numbers. How does RAC works ?

RAC is a sliding 60 day average I think.

Alex, you picked a bad time for your experiment. With the recent changes to work unit length (from 10 hours to 6), and the unusually large variance in CEP tasks, and the fixed length for NRW, your result counts can't be relied on.
Some of your figures, for example the Q9450, are clearly wrong. Thank you for your efforts. If the numbers can be made more reliable, then it will be a great resource. You misunderstood Sekerob's request. We have a rule that images must be no bigger than 600x600, for the convenience of readers (and due to forum limitations). |

I agree. The concept is excellent and you deserve credit for your efforts but the Q9450 results cannot be correct. Processor efficiency is almost linear with speed (for varying clock speeds on a particular model CPU). A Q6600 running at 3.6ghz (150% of stock) will be approximately 50% faster. You can see this just by running the boinc benchmarking utility from within the boinc task manager.
----------------------------------------What would be much more useful in my opinion would be to see average points per day for each model. That would eliminate any issues regarding variations in work units. The points system is supposed to reflect the efficiency of each type of system so average PPD (RAC) should be a good indication of processor speed. I don't think you need to do 60 days of data though. A week or two should be fine. In the mean time, could you please run boinc benchmarks (whetstone, drystone) for each machine and post the results. The FLOPs is the most useful information. Thank you.   |

Hi Alex, off topic could you please copntact me via e-mail (see link below). Thank you in advance. Can't find your email (?). (RAC) should be a good indication of processor speed. could you please run boinc benchmarks (whetstone, drystone) for each machine and post the results. The FLOPs is the most useful information. 1. Here is the table from other boinc site, some centralized project site: http://statsnstones.tswb.org/UserDetail.aspx?...4579b7b328f9f8f942a799d1a 2. I can't do the test you asked since some computers located in cities near Gaza Strip border at the south west and HAMAS terrorists bombard citizens in these areas with missiles daily (yes even after the military operation Israeli army did there) so until they stop, I won't go there. 3. I have only these results (what site is it anyway ?): *only Q6600,Q9450& i7 920 are 24\7\100% comparable http://statsnstones.tswb.org/UserDetail.aspx?...4579b7b328f9f8f942a799d1a - can I somehow get e-mail notification regarding new posts ? I didn't even know you guys answered until going here manually.

I see you have ignored the request above -
