[FaD] Calculating Points per Hour

[tgxiii]

Anyone know a forumula for calculating approximately how many points per hour a particular CPU will make? I saw SoopaStar's thread about his Athlon/Duron question, and blackbird answered that the Duron at 800MHz will earn more points per hour than an Athlon at 750MHz, 85 compared to 70. I was just wondering how you calculate that.

FaDSpy ( by Blackbird ) does that automatically, I think based on tables devised by THINK!

I'll go looking for a link,

Think uses a sort of benchmark routine based on Gigaflops per second.

I think that FadSpy's list of ratings is based on BlackBirds observation.

This is the list of ratings as referenced by Blackbird in FadSpy...

Celeron 333MHz=22 333 128K 'Mendocino'
Celeron 700MHz=70 700 128K 'Coppermine-128'
AthlonXP 2500+=170 1833 512K 'Barton'
AthlonXP 3200+=210 2200 512K 'Barton'
AthlonXP 2500+ @2.5Ghz=250 2500 512K 'Barton'
Athlon 750MHz=72 750 512K
Celeron 2.0@2.9GHz=180 2900 128K
Pentium4 3.2GHz=220 3200 512K
Celeron 1.4GHz=131 1400 256K 'Tualatin'
PentiumIII 700MHz=56 700 128K
Athlon 850MHz=81 850 512K
Pentium4 2.4GHz=168 2400 512K
AthlonXP 1800+=154 1450 256K
PentiumII 350MHz=27 350 256K
PentiumIII 1.0GHz=78 1000 128K
PentiumIII 650MHz=53 650 256K
Celeron 433MHz=31 433 128K 'Mendocino'
PentiumIII-m 1.0GHz=85 1000 512k
PentiumII 450MHz=30 450 256K
PentiumIII 800MHz=65 800 128K
PentiumIII 1.3gHz=112 1300 128K
Celeron 2.0GHz=120 2000 128K

Oh okay. I just thought there was a formula to determine the CPU rating. I guess it's just based on observation.

There is a formula, but they're not going to reveal any secrets. I got shut out pretty quick when I asked Keith.

Take the points from a job and divide it by the number of hours it took to complete it.

That's probably the best method for a particualr CPU under a particular load, as the figures in FADSpy are not set in stone, and can vary a bit (less now, it seems with the newer clients) based on a number of factors, including what other apps are running in the background, how much other work is done on the CPU whilst FAD is running, etc.

If you want a basic formula for AMD K7 based CPU's, try 93 x Speed in Ghz..

For example, and XP at 2.2Ghz will yield an average of 205 points per hour.

For P4's I'm not sure what the multiplier would be (probably 75 or less)

I just took the rating from my Athlon 1Ghz and We already know average points/hour is linear with NT based OS'....

[tgxiii]

Thanks, WoO. That helps. :)

How many points is an AMD 2.5 GHz(actual speed, not Pentium comparison edit: Sorry, this is an accidental lie, actually 1.75 GHz) Sempron. I'm probably going to have one installed in 1-2 weeks. My prsent AMD Athlon is 500MHz and gets 43-46 points. :eek:
