Apparently nVidia is releasing a Kepler version of Tesla on May 14. What seems very interesting is that it is a 7 billion transistor chip, the GTX 680 is 3.5 billion transistors.

Interesting. With the number it would be tempting to think 2xGK104, but given how crippled GK104 is in FP64 performance I can't see that happening in a Tesla product. If this actually is BigK, it's way ahead of when most people expected it to ship.

Actually NVIDIA is most likely just crippling in the drivers like they did for the GTX480 vs Quadro6000/Tesla C2050 by hobbling the drivers. Anyways I dont think GK104 has ECC support, so it is likely this new card will be GK110.

Watching as I have an itch for a gtx 680 for gaming stuff. Would also much prefer mining to go with the package. Right now I would choose the 7970 completely based on mining/gaming performance.

I think we are going to be watching for a long time because it seems nobody is interested in getting Nvidia to be competitive in mining against AMD Cry

It's not that they're not interested. They just know that they will only be wasting their time and think "Why bother?".

GTX 680 mining does work but the performance is very disappointing at the moment. I think there may be some gains from drivers in the future though, since I'm only showing ~70% power usage. However, I highly doubt the GTX 680 will ever be competitive as a mining card.

Showing 123.40 Mhash/sec in Phoenix 2.0.0 with the following settings:

Code:

[cl:1:0]
    kernel = opencl
    name = GTX 680
    disabled = False
    worksize = 256
    vectors = False
    vectors4 = False
    bfi_int = False
    goffset = False
    fastloop = True
    aggression = 2

Vectors seem to reduce performance. Enabling goffset will cause the miner to error out and exit after about a minute. GPU clock was a constant 1241MHz for the test. (using +144 offset) Maximum load temperature was 67 C.

Or maybe the GTX 680 is the card that is for gaming only and designed to crush 7970 prices ?

Thanks !

YES... please! Then again, there's the 7990 down the pike.

Then you'd have to decide between a $499 7970 (if the price drops) or $849 7990 for each slot.

Please let the 7990 hit 1.3Ghash/s.

Nvidia just cut all integer and double precision support to fit 1536 crappy shaders. We have to wait for the high end Kepler.

Care for a link ?

As much as I love AMD vs Nvidia mining competition it really does look like Kepler totally SUCKS for mining Cry

I just tried it now but it doesn't seem to work very well. Desktop is completely unresponsive and the GPU usage doesn't stay pegged at 99%.

I have tried to recompile the Ufa-miner and the rpcminer-cuda, but for various reasons it didn't work.
Now I have written a very simple miner using the latest CUDA toolkit, just to see what the speed is like.
Since I have written the kernel from scratch, and the program is not doing longpolling, there's some room for improvement.

If somebody with a GTX680 would like to try it you can download it there:
http://www.sonstiges.org/bitcoin/ICU-Miner.zip
Usage:

Code:

ICU-Miner.exe URL username password devicenumber gridsize blocksize

(devicenumber, gridsize and blocksize are optional)
For example:

Code:

ICU-Miner.exe http://mining.eligius.st:8337/ 1BtVLjUkAzF9wZGHfKzzsPivgNAn4DTp1Q joshua

Here's the ugly source code:

Too bad I don't have a GTX 680.

Somebody needs to try this ASAP !

Yeah, as you guys said it just doesn't seem right in theory. Whether the CUDA miner or something else needs to be adjusted or re-written for the Kepler architecture is just my guess, it's too bad to not see it mine well.

FWIW, Folding @ Home (Stanford) has also said they have to recompile their program to work with the new architecture. Thus while normally Folding is a strong suit for Nvidia, it also is "broken" on the Kepler cards for the moment.

Might also just need a newer driver. Hopefully if that's the case, Nvidia won't take 3 months to release one. Normally it seems like they get new cards' drivers out very fast (updated ones I mean, rather than the stock). Here's hoping!

Folding @ Home is broken because nVidia broke it. The cards have way less DP/SP floating point performance than a 560 Ti. It's part of nVidia's new tactic of making their lower end architecture useful only for gaming.

And despite that there are ppl who love nvidia and hate amd. Nonsense.

Seriously, who want to buy a nvidia? Not me.

Green Mining 85% Cheaper

F@H has not released a Kepler aware core with optimizations yet. Using the currently available cores GTX680 is performing on par with GTX 560 Ti.

Bumping this because I want some REAL results this time around.

I think that people have given up on the Kepler for mining just because the kernels we have now are totally NOT optimized for it and that is why it gets only 100 MHash/s.

With more kernel development I am pretty sure that this card will be a killer mining card.

Maybe someone is holding back the code and mining at over 400 mhash/s Huh

Too bad I am not a coder otherwise I would have done this myself.

I just find it really hard to believe a GTX 580 gets 140 mhash/s and this POS Kepler gets lower at 100 mhash/s ...

Also, while we are on the subject, how is this doing for F@H : did they develop that new Kepler-optimized client that Nvidia was promising or not ?

just means amd is gonna get that much more money from people that want to use gpus for gpgpu since amd gpgpu is hugely better than anything nvidia has ever offered

Okey Dokey Lokey

Ew, This is such a double edged sword for me, Im an AMD fanboy, And i was going "HA nvidia sucks a mining ahaha amd ftw"
And then the gtx 680's were announced, And i thought "oh shit, 1536 CUDA cores (assumed SPcore equivalency) looks like it'll get around 300ish! Good job nvidia! now AMD will try harder!"
annnd 110mh/sec...
It just doesnt seem right... I mean like, Yeah i was hoping for failure, but not the kind of business wrecking failure
