Nvidia BigK GK110 Kepler Speculation Thread

The upcoming Tesla K20 card will be equipped with a whopping 2880 Shader / ALU processor encounting monster.
Update: new information shows that there actually might be 16 SMX cores and thus 3072 Shader processors on GK110.

We do have a picture of the chip for the sake of an SMX count.
Not sure where to find the 16th.

 

Maybe nVidia took a page of AMD and they showed only artists impression of GK110 die?

 

New stuff from Inside Kepler Session:

7 SMX, 1.5 MiB L2, 255 registers per thread adressable, 4x 16 FP64-Units per SMX according to block diagram and a separate path from texture cache to SMX, 66% lower ECC overhead than on Fermi

I know I'm late to the party, and this was posted a while back. Can you share any more info on your app? I've been doing some tinkering with Microsoft Hyper-V and RemoteFX platforms, specifically around the "shared" 3D acceleration that RemoteFX can deliver across multiple simultaneous streams via any 3D accelerator card that has a WDDM driver available. Even an ATI 4850 provides an acceptable amount of performance for 'easy' games across three separate Win7 VM remote sessions.

I'm not entirely sure of how they do it, either.

 

Thanks!

 

Interesting:

"SMX: 192 single‐precision CUDA cores, 64 double‐precision units, 32 special function units (SFU), and 32 load/store units (LD/ST)."

 

So... the texture cache in Kepler now has direct read-path to the SIMD lanes? Quite useful.

 

So...
1/3rd rate DP
Access to texture cache
2x L2
4x Registers
2880 CCs
240 TUs

I wonder if it will be substantially faster than GK104 in games?

 

Another interesting bit:

 

>1 TFLOPS of 1/3 DP at ~85% efficiency gives >3.53 TFLOPS SP, which indicates >613 MHz with 15 SMs, >657 MHz with 14 SMs, or >707 MHz with 13 SMs.

Interesting those hypothetical clocks are so low….

 

Depends on clocks but it's almost guaranteed to be worse perf/w unless nVidia found additional architecture tweaks. Too bad they didn't announce a release date for consumer versions.

 

I'm not sure it will be worse perf/w. Sure at the same clocks it would be. But chances are clocks (and hence more important voltage) will be lower which can improve things a lot. So might be something like 50% faster with 50% higher power draw in the end.

 

This thread was lacking bitcoin talk but apparently they should be happier now

 

Does that mean DP units can be used as additional SP units? 2880 + 960(or even x2)

 

No. First, nV would have told us so and would advertize the higher speed. They explicitly say, that the co-issued instructions (to a DP instruction) cannot read from the register file. I imagine there can't be too many instructions of this type.
And as a second point: the actual implementation will probably look differently than what nvidia sketched.

 

I still can't understand the benefits of designing SP/DP unit seperately..

 

I doubt it is really separate...

 

Well, unfortunately they will release GeForces with GK110 only in 2013.

But, does it mean we will see GK114 as GTX 760 while a little bit later GK110 as GTX 780?
