They limited the 64 bit double precision math capability and PG is 32 bit single precision. I'm guessing that DirT is also single precision but I'm not positive. MW would be limited, but as pointed out, ATIs have always had a big advantage there.

OK, so to run the typical CUDA projects - i.e. PG and DiRT, with perhaps occasional Collatz - the 680 is indeed the good choice now?Originally Posted by Bryan
at PrimeGrid, the PPS and CW Sieves don't require double precision, but the GFN prime search does.
About 18 mins ago, PrimeGrid proved the GTX 680 to be about 40% slower in double precision than the 580. Good thing i fueled the flames on that one to get it done sooner rather than later. The test was done using the Genefer app's benchmark, not by running a Genefer WU itself, which eliminated any possible variances due to WUs being different lengths.

DrPop, I think you should see a few extra patients a day and do a bulk buy on the 680's...then send me one...or two!OK, so to run the typical CUDA projects - i.e. PG and DiRT, with perhaps occasional Collatz - the 680 is indeed the good choice now?Sphinx would like that! She told me so!
LOL!DrPop, I think you should see a few extra patients a day and do a bulk buy on the 680's...then send me one...or two!Yeah, and Kim just told me Kat needs new shoes and she'd like to save up $ for a trip...go figure...what timing!
Seriously, though - I am going to figure out how to swing something new for the rig...either a new CUDA or one of the new AMDs give me about a week or so.
What I don't know is - this the best time or not? I mean, what are they going to introduce in 2 or 3 weeks? Or...maybe this is it, and we'll be waiting a long time for anything better now. I don't know, but I wish I did.
I take that as a "no" on the whole Sphinx idea. Wow...Kim & Kat are really putting a damper on things here is NC.LOL!

Ah, here's what I'm talking about. http://www.anandtech.com/show/5699/n...gtx-680-review In this article Anand refers to both a GK110 and a GK114 as "Big Kepler".
What I want to know (and no one seems to) is, when will these suckers hit the market, and how much $ above the 680 will they be?
Buy a 680 now. Sell it for funds when the better one comes out, in late summer. Waiting is just losing credits every day....Ah, here's what I'm talking about. http://www.anandtech.com/show/5699/n...gtx-680-review In this article Anand refers to both a GK110 and a GK114 as "Big Kepler".

August, at best. But seriously...those things will murder your electric bill. You're talking 250W - 300W just for the single GPU card....seriously...
BUT! You asked if anything new would appear in the next 2 or 3 weeks. Yes. And some good stuff, i might add. Hold on a sec while i dig up a link...

on the AMD side, they may get the 7990 out by then. no guarantees though
