Used 660 ti into the mix

[cineon_lut]

I just picked up a 660ti to add to to the arsenal. I have 2x 570s, and 1x 560 now. They're all running stock on Collatz, (one 570 is a POS and needs to be down-clocked to stay stable).

However now with a new 660, should I start looking at multiple work units running simultaneously? What would be the best use of the card to get the most points?

Run a few wus to check it out. I'm really curious what times it will produce. IIRC, the 6xx series wasn't as strong a cruncher as the 5xx series. I could be full of it though. The memory isn't what it used to be, according to my wife.

The 660 Ti will be every bit as good as the 560 Ti, but not really tons "better". For crunching, you have to take the 600 Series and newer GFLOPs ratings and cut them in half. So it is virtually a tie with the 560 Ti. One good thing is the 660 has a higher stock clock and Memory MHz (likely can push it even further with Afterburner than you pushed a 560 Ti), and even though it's 192 bit memory path is less than the 560 TI's 256 bit, what really counts (I think) is the GB/s the memory can do. And here the newer card bests the older card by 20GB/s, so crunching something memory intensive like Einstein WUs, for example, should go slightly better on the 660 Ti.

The one other good thing is that 660 Ti will burn 20 watts less than the 560 Ti full out, so even if it doesn't give you a whole lot more credits / day, at least it's doing it with less cash burn. :)

Hmmm. Sounds like I made a bad choice. What would be a good upgrade? I'm thinking of canceling the transaction. I haven't paid for it yet.

I got it for $192 out the door, but I was getting 570s for about $110.

GFLOPs / watt, nothing NVidia makes can touch those new 750 Ti Maxwells. They are almost on par with the AMD GPUs in that regard I think. :)

Yeah, the 570 would whomp all over the 660 Ti, heck (in my opinion), that was the last "really good" crunching card NV came out with until the Titan / new Maxwell series.

I better edit this to add: The 570 will give you a couple hundred more GFLOPs, but burns juice at the rate of 6.4 GFLOPs/W whereas the 660 Ti is sipping less juice, burning a rate of 8.2 GFLOPs/W.
So the 570 will be more credits per day, but the 660 Ti is somewhat more efficient with your utility bill. ;)

Does such a thing exist?
