GT300 to Pack 512 Shader Processors
A real monster seems to be taking shape at NVIDIA. The company's next big graphics processor looks like a leap ahead of anything current-generation, the way G80 was when it released. It is already learned that the GPU will use a new MIMD (multiple instructions multiple data) mechanism for its highly parallel computing, which will be physically handled by not 384, but 512 shader processors. The count is a 112.5% increase over that of the existing GT200, which has 240.
NVIDIA has reportedly upped the SP count per cluster to 32, against 24 for the current architecture, and a cluster count of 16 (16 x 32 = 512). Also in place, will be 8 texture memory units (TMUs) per cluster, so 128 in all. What exactly makes the GT300 a leap is not only the fact that there is a serious increase in parallelism, but also an elementary change in the way a shader processor handles data and instructions, in theory, a more efficient way of doing it with MIMD. The new GPU will be DirectX 11 compliant, and be built on the 40 nm manufacturing process. We are yet to learn more about its memory subsystem. The GPU is expected to be released in Q4 2009.

Here's hoping that ATI will continue their good run and will have some hardware to compete with it. I don't think anyone (outside of nvidia) wants a repeat of the 18 months of G80 dominance.
ill just stick with my 4870x2 XOC till that comes out then we will see what ati has
(hint: other hemisphere)
For some people 1024x768 @ Medium with 30 FPS = "runs."
For me, it's 1920x1200 @ High with 40+ FPS.
stupid crysis, i struggle for 60 FPS on very high with no AA.
Running a game
Running a game at playable levels (for me)
Maxing a game
are 3 different things.
Summer - Autumn - Winter - Spring

America:
Winter - Spring - Summer - Autumn
Settled?
If this is to be true, what a beast... I just hope that ATi has something competitive to keep prices down!
Devs are going multiplatform anyways, and ittl' be held back by console technology.. not unless another would be dev team would gamble in making another PC exclusive title that would profit 1/3 vs a multiplatform title, and would probly just be torrented.. We wont be seeing any title that would utilize this much power. not until xbox 720 or PS4 arrives at least.
Complain about TPD instead! not the stock cooling solution if its quiet and effecient.
This card looks mighty, dunno what theyve done, obviously this is indeed 25 NM smaller than GT2xx though.
I wonder if ati got something up their sleeve aswell =)
If they had made significant progress on power consumption, that would surely have been touted as one of the GT300 features.
