I'm running an approximately full CADO run on C188_140_113. ETA two weeks, maybe a bit less.

I have a GTX 560 GPU. A low end in today's standard.

I have run poly selection on C188_140_113 for two weeks on a GTX 650 Ti. I guess that a GTX 560 is a bit faster.

I'll switch to C188_149_78 now.

Next time please say something, so that I don't waste my computing time and power.

Interesting comment.

I returned my other GTX 560 for RMA work and it was claimed the replacement parts where out of stock. They offered me a "new and improved" GTX 750 as a replacement if I accepted.

After receiving it I had a gut feeling it was not any better.
Your thoughts?

VBCurtis · 2016-06-03, 02:20

For math-related work, I imagine it's nearly as fast while using ~half the power (maybe less?). I'd trade a 560 for a 750 every day for the tasks we do here (no idea about gaming).

Gimarel · 2016-06-03, 06:30

I use http://www.mersenne.ca/mfaktc.php?sort=model&noA=1 as a rough indication for the integer performance.

According to that data you should try to get a 760 for comparable performance to the 560.

C197_147_136 is the last big job for GNFS.

I should be able to start on the C197 tomorrow (probably afternoon/evening). I'll start with A5=1 and just run for a while.
