It's a shame that nVidia cards perform so badly in OpenCL calculations.. Otherwise GTX 680 is overall way better card than HD7970 for example.

Well they are pretty good at OpenCL and even better at pure CUDA but integer math has always been a weak point in NVidia's product line.

It's hard to believe for me, that a card with essentially 3 times the cores than the 580 performs worse than it.

Get the GTX680 running with cgminer.

Seems you have enough posts now to post outside the newbie thread. I'd recommend checking the Ufasoft thread for possible answers:

Sorry, I can't post in the main 680 thread because I lurk.

Hey, just got back from the store with a 680. Here's a quick benchmark for people, and it's not looking good so far.

This is a stock EVGA gtx680, with latest drivers (301.10) and ufasoft 0.28, run with -t 0, under win7 x64.

Getting around 105Mh/s.

Cry

Thankfully I didn't buy it for mining.

Is that a joke or real?
Even my GTX580 gets about 150MH/s, but that's on cgminer.

105MH is a completely useless number, that card might not be a mining card, but you did something wrong if you can't get at least get to the 580 numbers.

Not a joke, but again, here is EXACTLY what I did. I installed the card, and the latest drivers, in a win7 x64 box. I downloaded ufasoft 0.28 binary, and ran it. THAT'S IT. I didn't tweak anything, I didn't do a lot of research, I just wanted to see what would happen, and in the main thread someone said "run ufasoft" so I did. I didn't have time to compile anything. Now that more people probably have cards (I haven't looked at the main thread yet) there's better benchmarks posted. *shrug*

Someone said "Try RPCMiner-CUDA with the CUDA dev kit, something doesn't sound right." in the main 680 thread.

Simply recompiling the source code with the new CUDA 4.2 toolkit would probably help.
But I don't think that the speed would be much faster.

Frankly we all knew the result will SUCK until some people get off their asses and start developing a Kepler miner.

This should get WAY more than a GTX 580 ...

Wow, that was a sad number...

I guess you would get some higher numbers with other settings. I am not into nvidia, but I assume ufasoft would give you the CUDA-benefits...

Just by looking at the mining hardware comparison wiki, some nvidia cards use rpcminer-cuda, but I am sure some other people than me can come up with settings you should test to get improvements.
