Kepler 28nm taped out

Written by Fuad Abazovic


Works well
The successor to Nvidia’s Fermi architecture, a certain GPU that goes by the name Kepler has already been taped out.

We have multiple sources to confirm that the new 28nm chip is alive and that it looks quite well. Nvidia didn't have any major obstacles with the first tape out, but naturally there is still a lot of work to seal the leakage, and make the chip generally better. This is nothing unusual for a new chip, and getting from 40nm to 28nm is definitely not a walk in a park.

Kepler naturally gets a lot of changes to Nvidia's GPU and you can imagine that with the same maximal TDP, you can squeeze significantly more transistor and get much more power.

The optimistic projection is to see Kepler in retail in Q4 2011 but some sources suggest that this won't actually happen this year, as TSMC needs a bit more time to make the 28nm more mature.

Current generation GPUs are already hitting the performance wall at 40nm and the industry has a lot riding on the 28nm process, but fear not. For the moment, both AMD and Nvidia seem to be on track and we might see the first 28nm chips by the end of the year, but mass availability comes a bit later.

AMD's 28nm GPUs taped out months ago. Are Nvidia behind with a node transition AGAIN? What a surprise.

Tape out to launch is never less than six months. Its good that its taped out but unless this occurred really early in the month, there's just no chance.

which part of the Kepler architecture taped out anyway? Kepler is not a GPU, it's an architecture, as fermi is.

In that respect GF100, GF110 and GF104 etc, are all Fermi chips.

If the kepler that taped out, was the chip that will go to the GTS 620 or something, that's not so great news really.

"Works Well" according to Fuad... make sure you know what you say.

OMG do you know anything? They design the architecture (in this case Kepler), and once complete, its scalable, so from that, they make EVERYTHING (workstation, desktop, laptop) from that. And from that, they can shorten the memory bus, use less or more memory, disable shaders, raise/lower the core clock, so they have cards in every segment. Damn i can't believe this crap repeatedly gets rated up. You might as well go back to comparing x86 (AMD Fusion) to ARM architecture. At least that was funny, this is not...

Usually true, depending on how many spins you have to do to get production silicon. AMD (then ATi), has released A1 silicon before in the past, but it's rare.

Probably the fattest one, they tend to release the enthusiast parts first.
