My speculation is it will be late.

Damn, you're fast -- I was about to fire up that thread for "Kepler".

I guess it's too early for "Maxwell".

Fast? I even went via photoshop in between
(and noticed afterwards that I had accidently zoomed out the video tab in ie9 so it's smaller than it should)

I'm happy to learn that Fermi was released in 2009, and that Tesla was released in 2007. Kind of makes me think about how reliable that "2011" will turn out to be for Kepler…

Nvidia signs up with Global Foundries


Maybe this has something to do with "2011"....

Well, considering the 2,5x increase in efficiency , it should be a 28nm chip. So well past mid-2011.

And Maxwell should be a 20nm chip.

Edit: in that slide Cypress would be just between Kepler and Fermi, at 2.8 DP Gigaflops per Watt

28nm Kepler

Focus is apparently on performance/watt with Kepler aimed to be 3-4 times more efficient..

I could be wrong but the graph seems to show super linear growth in DP flops/W. I guess 2013 is when last call for ff hw goes out.

Also, source?

Jen-Hsun's keynote

The growth is extremely similar to what AMD has had so far in "SP flops/w"

This roadmap isn't correct. It was more like this:



Looking forward to place Cayman in there

Is this a roadmap for power point slides or actual working boards with non-rebranded chips inside them?

And the hardware of their first Tesla generation was ready in November 2006 or April 2007.

Maybe Maxwell will power Playstation 4.

FWIW:
http://en.wikipedia.org/wiki/Kepler
"Kepler also incorporated religious arguments and reasoning into his work, motivated by the religious conviction that God had created the world according to an intelligible plan that is accessible through the natural light of reason." and "As he indicated in the title, Kepler thought he had revealed God’s geometrical plan for the universe."

Anyone else hearing "Big dies make good GPUs?"

"Kepler claimed to have had an epiphany on July 19, 1595, while teaching in Graz, demonstrating the periodic conjunction of Saturn and Jupiter in the zodiac; he realized that regular polygons bound one inscribed and one circumscribed circle at definite ratios, which, he reasoned, might be the geometrical basis of the universe. After failing to find a unique arrangement of polygons that fit known astronomical observations (even with extra planets added to the system), Kepler began experimenting with 3-dimensional polyhedra."

Even more geometry? A Polymorph engine for each ALU perhaps? =)

I would say that a special version of Kepler will power PlayStation 4.

This roadmap is about chip codenames, not the Tesla product line. Here, Tesla means GT200.

That'll be great if it is, and the idea of a new line-up in January from nVidia is a big plus too.

"Cuda GPU Roadmap". And which was their first Cuda architecture? Hint: Not GT200.
They used Tesla for G80 GPUs. And before Fermi they never used names for their chips.

So do they plan to abandon the approximately yearly release cycle of the good old days, or will there be some kind of refreshes in between?
