Re: [XPM] Working on a GPU miner for Primecoin

I'm having a hard time figuring out which direction price is going to shoot when this GPU miner is released.  Will the price tank because there will be an abundance of new coins on the market (which somebody will surely dump for a shitty low price), or will price increase with the new interest in the coin that this release will generate?

This is probably a crystal ball question, but I'm sure somebody in here has some insight.  Either way, it would most likely be completely useless for me to donate if I only have one 7950, right?
Depends on speed.  We know sieving is running about 25x, but how much of the CPU time was used for sieving and how much for fermat testing?  Let x = CPU sieve time and y = CPU Fermat time.  If x=y (50/50 split) then GPU = 2% for 52% of normal time = 92.3% speed increase.  If x=9y (90/10 split) then GPU = 3.6% for 13.6% of normal time = 635% speed increase.  if 9x=y (10/90 split) GPU = .4% fo 90.4% of normal time = 10.6% speed increase.  These are extremely rough figures, communication times between GPU/CPU will also apply.  Maybe he'll solve Fermat testing on the GPU and get a full 2500% speed increase.  Short answer: too many current unknowns.
