Kepler lineup

Good finds. So gtx680 will be most likely about the same speed as my gtx590. Not bad, given the current talk about it being crippled gpgpu capability-wise. Still probably not good enough for me to ditch that 590 and buy 690 (supposed dual 680), once its out (in May?). If there is indeed big Kepler card though, at some point, and if its going to be in dual-version as well, i would definitely consider it.

The most interesting thing is that EVGA is going to release the GTX 680 FTW 4GB ! More VRAM for big scenes !

so, when will a compatible version of octane come out?

in some other thread they mentioned that update is going to be in few weeks, so I believe they will touch this issue too. Anyway, at least for that doesn't matter so much now, as I will be waiting for 4GB models =)

actually that's pretty cool. & probably they will get one of the fastest cards comparing to reference designsome extra cost =)

One issue that I found reading lately is that cooling is very important for those, if they reach certain temperature they basicly downclock themself, so actually if looking to multi GPU setup, water cooling will make a lot of sense as it allow to operate in lower temperatures and at the same time run at maximum speeds or even OC'ed.

not what i've seen so far with my 680 (though not in "real" computing). also the max. power consumption is lower than it was with the gtx 580, so i would expect even lower temps already because of this fact...

is there any other way to know what the cuda performance will be?

if anybody has something better than the synthetic benchmarks i already did, tell me and i'll throw it on it...

There are benching blender cycles atm., looks not good for the GTX 680.

(i'm going to keep it in the public forum, maybe it'll give us a little publicity

Is cycles double precision then?

That's a bit sad....Geforce crippled for cg apps and now Cycles... and other gpu perhaps stuff like nodes, video editor....
I'm still hoping its OK for Octane.

How many folks will want to pay for top end Quadros/Teslas.....assuming they are different.
I guess they couldn't fit everything on the die but obviously less openCL and dp cuda performance than the last generation is a bad marketing move.
