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.Source: Hardware-Infos

it is rumoured, that rv870 has 1200sp, 512bit bus, and MCM ready ~1,9tflops.

2 rv870 mcm (x2) 3,8tflops
4 rv870 dual-mcm (x4) 7,6tflops

but for gpgpu gt300 will be very good.
Where did you get that info from?

From an another forum by an "amd insider" guy.

I forgot the die size: 160-170 mm^2.

But nothing is sure :)

I hope this isn't true, they are going to need more than that...

haha I new it would not make it a day, with out AMD/ATI ppl trying to steel the thunder!
Just remeber tho NV 240sp > ATI 800sp so 1200 is not going to compete, but they still have time.

ATI may have sorted out how they use Shaders though, stop speculating and putting ATI down (I am by no means an ATI fanboy, just NVIDIA hasn't been at the right price point when I've bought machines). NVIDIA has their rebranding strategy while ATI has their innovation strategy, actually at thirs rate we may see some innovation from NVIDIA.

I agree with you in part there although I still beleive the greatest innovation in the last 3 years was NVidia's G80, the origional DX10... it's the only truly groundbreaking architecture we have seen since the days of the 800/850 series from ATI (IMO) :)

Just glad it's not rebranded or just a die change. If Nvidia end up to be a winner again. They gonna charge you an arm for it.

Lol, every time this GPU is discussed in forums, the hype increases and so does the potential cost of the thing on release.

Still waiting for official specs for RV800 from AMD before I have any real opinions.

Oh AMD will come out with something on par with it for sure. Still great to see

Obviously, but my opinion of nvidia right now in far from good based off my last few purchases. I really hope AMD has something to compete with this, because the specs for GT300 already look really good.

Hah, Quarters in business terms have nothing to do with seasons or locations. It's simply the 3-month sector of a calendar year. Q4 = October through December. Now, you could dig deeper into Fiscal years, which are determined by the company. For instance, the company's Fiscal year that I work for is April to April.
the uhh, seasons are different depending what part of the world you're in. december is summer here.

Lol why? This can still be a great and powerful card even if RV800 is also, I dont go with this "Green or red is better so the other one is not any good" routine, I think pretty well most of whats available at the moment is pretty damn good whether it be green or red :p

its an overkill for the current generation of games, there is no real need for this card and it will cost probably 600 euros/dollars, i dont find this logical when you can max out any game today with a single 295/4870x2. i dont see the point.

The point is that people will buy it. Nvidia will make money. Their shareholders will be happy. And the world will be a better place. :toast:

your not thinking about game developers and how much new rope they will have soon as nVidia releases this card they will create medium and low end variants with less shaders and you have a new market for high end gaming.

Because its not out today. it will be out in 6 months, for the same prices as the high end cards today and in 6 months new, shiny games with nasty graphics requirements will be out.

i just want better looking games....i don't see the point of having such a card if you would get over 100 FPS on every game out there maxed out...you get me..i first want better games then! i want better cards. its a funny world. game developers are working hard on putting a leash on todays high end card and not the other way around. i wanna see what the RV870 is all about

IDTech5 is SM3.0 (OpenGL 2.x, DirectX 9.0c), and UnrealEngine 4 is ~three years away from implementation.
