I did a PPS Siev and received 3371 credits. I think there is an error, the TRP sieve only gave out 120 credits and I don't want to receive anything I'm not suppose to get. So is this right? I mean is there an incredible need for PPS Sieving that the project is giving out over 3k? It only took my graphics card 46 minutes....

Is there a bonus for finding factors?

It does take a significantly longer time on CPU.

TRP Sieve does not have GPU, but compare CPU speeds:
Recent average CPU time: 0:38:01

PPS Sieve
Recent average CPU time: 25:13:42

There is why it is so much extra. Processing on a GPU is much faster, even for the GFN and AP that use it. For LLR there is no significant difference and that is why there is no LLR GPU apps.

If TRP Sieve was done on GPU, it would probably take less than a minute.

No.

And actually the opposite is true with respect to bonuses. The TRP-Sieve tasks get a 10% credit bonus because they're part of a conjecture. PPS-Sieve gets no bonus.

The PPS-Sieve tasks get about 30 times more credit for the simple reason that those tasks are about 30 times longer.
