f@h nvidia ppd drop

post #1 of 22
Thread Starter 
I went on stanford forum and started a thread on the nvidia points drop and got this reply from one member there that helped me accept the loss of points. This is the result if the wu's we are working on were benchmarked with an nvidia 8800gt. instead of an ati gpu.

"That 8800GT folds the 1392 atom WU in 3 hours, 39 minutes, 51 seconds.

It folds the 973 atom WU in 2 hours, 8 minutes, 57 seconds.


The formula for benchmarking is:

Points = 1500 * (DaysPerWU)

1392 atom WU = 1500 * 0.152673611 = 229 points instead of 511.

973 atom WU = 1500 * 0.089548611 = 134 points instead of 384.


The result?

ALL Nvidia GPUs lose 55% of their current points folding the 1392 atom WUs.

ALL Nvidia GPUs lose 65% of their current points folding the 973 atom WUs.


By comparison, the recent Nvidia points drop many are complaining about is only 15 - 35% on my 8800GTs."

It looks as if it would be alot worse if nvidia cards benchmarked their own wu's.

Heh, I won't say another word about GPU PPD after this. Especially to Stanford.

Did they change their valuation of the WUs or something? Sorry I don't watch my output closely anymore...

markt had mentioned using nvidia gpus as the benchmark instead of the current ati card. he then found out if that happened, the WUs would lose atleast 50% in each WU.

helps to tell us that it isn't as bad as it could be. i'll accept the losses with this.

I don't understand.... I have read this a couple of times and can't figure out what is going on. How does this explain the PPD drops I am getting?

It's monday morning...I am just going to blame it on that.

so pretty much the ati benching rig for stanford takes longer to process those said WUs and thats how they have come to get those points.

IF we benched the WUs with say an 8800GT, the worth of those WUs drop by atleast 50% as the 8800GT goes through those WUs much faster than the benching rig.

your ppd drops are most likely fluctuations of WUs. we were just talking about how we are very accepting of the current nvidia ppd drop and not bicker anymore with this info.

I suppose they could bench on an 8400GS. That would be nice.

Or how about leaving well enough alone? They don't seem to get that! There is not a logical reason for the continuing changes they impose upon everyone!
