NVIDIA Kepler speculation thread

AFAIK, the original source of information was Theo Valich's piece over at VR-Zone, all others are referencing him. And he was writing power planes. With an "e". If that makes it more believable is another question as the earlier news on heise.de he linked indeed mentioned the dynamic clock adjustment, but first on a far smaller scale (+7% max) and secondly heise.de didn't talk about power plan(e)s at all.

 

If it is power "plan" then this might be referring to closed loop voltage + freq control of some kind (mobile SOC's do this a lot).

If it is power planes, then I guess that word is loosely used. Partitions are routinely power gated, but number of power rails/planes itself is going to be a very small number.

 

If Nvidia can win on performance/watt then I am sold. Efficiency and eyefinity were Ati's best strong-points with their GPU.

 

unless google tricks me, PHK has the card with press kit and return from US.. also says it's 195W and faster than 7970..

Excuse i'm with mobile device, so i can't translate now...so: http://www.computerbase.de/news/2012-03/debuet-von-nvidias-kepler-ende-maerz-als-geforce-gtx-680/

 

Only a summary of recent information/rumors.

btw.
According to PHK GTX 680(?) could be ~500 points faster than HD 7970 in 3DM11 X-score.

 

300 faster with 29x.xx driver and 500 faster with 300.xx driver?

 

also PHK expects a performance driver by AMD in reference to Pitcairn..

It seems previous performance rumours talked about 670ti then...

If this is with 195W... this would be the most efficient chip ever...

 

So ... they basically set one overall power budget for the "core" and the shaders - and can seperately send either one of them into "turbo-mode" when encountering asymmetrical shader/core loads?

I guess those Bitcoin miners just placed some preorders

 

Seems to me that those who didn't buy 7970 because it's "not faster enough" won't be buying this either.

 

15% faster -by 3d mark-, smaller, cooler and cheaper -at least in performance per buck will be surely-?. Enough reassons to buy above a 7970 imo.

 

Pricing is the big question:
$499+ - sub-performing upgrade offer to GTX 580
~$299 - a bit over-priced upgrade offer to GTX 560 Ti

 

Waah?

 

There is no way this thing will be priced at anything below HD7970. It's just common sense.

So we have two disappointed groups here: those who think it will be $299 and those who think this thing is performance monster.

 

GTX 560 Ti was $249 and also a bit higher priced than previous G...4 GPUs.
50-80% more performance would be a nice upgrade offer to GF104/114 users, even at 30% higher price than they used to pay for this cards.

Its a 256-Bit 2GB performance card with only ~300mm² chip.

 

That assumes it's actually at least as fast, if not faster. I have my doubts about that personally. It takes a miracle to get that huge performance increase with significantly smaller die having much less bandwidth and using less power. It is possible they have pulled a rabbit out of their hat but it's rather unlikely.

 

Tahitis is 350mm. It's not that out of line. Just that Nvidia was always way behind on performance/mm before.
