GeForce Kepler 104 (GK104) Packs 256-bit GDDR5 Memory Bus, 225W TDP
NVIDIA GeForce Kepler (GK104) will be NVIDIA's first high-performance GPU launched, based on its Kepler architecture. New reports suggest that this GPU, which will succeed GF114 (on which the likes of GeForce GTX 560 Ti are based), will continue to have a 256-bit wide GDDR5 memory interface. An equally recent report suggests that NVIDIA could give the front-line product based on GK104 as much as 2 GB of memory. We are also getting to hear from the INPAI report that on this product based on the GK104, the GPU will have a TDP of 225W. What's more, NVIDIA is gunning for the performance crown from AMD Radeon HD 7900 series with this chip, so it suggests that NVIDIA is designing the GK104 to have a massive performance improvement over the GF114 that it's succeeding.

If Nvidia's "middle" card would to end up as powerful as AMD's top cards - that would make for a serious advantage for Nvidia's flagship cards. Which would in turn make those cards terribly expensive.
On the other hand, it does bring back memories of HD 4800 cards slacking behind GTX 200, but being super cheap and good buys.
Bring on the competition! :rockout:
Neither ATI nor nVidia are allowed to have a significant lead one over the other because, if one of them do, there will be no price wars which will mean pricier cards for us consumers.
Sounds like a revision to me, not a new design. And 225W is enormous. Shrink to 28nm and new design should result in similar performance at half the power, ie 560Ti performance at 90W, or similar power envelope 150W but double to triple the performance.
Somehow 225W seems all wrong, unless, they are aiming at performance of 4x, which I would say is physically and technically impossible unless their transistor count has gone through the roof, and this chip is the size of a football pitch! (And essentially SLI on-chip).
People can see for themselves, right now its all speculation.
To me, going from GF104 to GK104 with a 55w tdp increase and still using 256bit just doesn't add up for me.
And if the power numbers are to be believed, then I would think this card to be very fast. I thought Nvidia released slides that said Kepler and the subsequent releases would double or triple speed. Maybe they are following through on this. :rockout:
Don't they see what Intel does with their processors.
