Hi guys,
I am new to Octane and the forum, this is my first post.
But I am very excited about the development in the Nvdia GPU market, as it just happens right now.
As I understand, the new Kepler GK104 Chip needs CUDA 5 for its best performance.
CUDA 5 preview version is available for developers since yesterday, the final Version will be out in Q3/2012.
Here is the press anounce, sorry only in german, as I am located in germany.

About Single and double precision and the Tesla K10:
Tesla K10 uses the same GK104 chip (2 of them), then the GTX690 uses (yeah, its out since some days)!
And both Cards seem to have the same single presision performance!
Advantages over the GTX690 seems only to be the Memory (K10: 8GB, GTX690:4GB) and lower heat generation in terms of lower clock speeds (K10: 745Mhz per GPU - 2,28 TFlops per GPU, Geforce 680: 915Mhz, whats also a performance disadvantage for the K10!). Both cards have 3072 CUDA Cores!
Nvidia markets the K10 only as single precision card, not as double precision card, cause it`s double precision performance is very weak (190Glps)!!
Can be read here, only german, too, sorry.

Tesla K20 with high double precision performance and GK110 Keppler chip will be out in End of 2012, and will have 2880 CUDA Cores on a single chip!! The first Geforce GTX with GK110 will be out in early 2013.

So what does it mean for octane users!?
We dont need a Tesla K10 for 2000 bucks, instead a Geforce GTX690 would have an even better performance for about 999 bucks!
And: We may have to wait 3 or 4 month from now for CUDA 5 release and a new octane release, that ist fully supporting CUDA 5. Then I think, that the 3072 CUDA Cores from the Kepler will at least behave as the Fermi Cores and we will see a huge performance step up, like 4x to 6x from what we are used to with 1xGTX580.
What do you think?
