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

Im really really looking forward for this product. I am very confident that this card will be a beast, provided Nvidia adopt DDR5 and get it right aswell as the above stated features.

I doubt AMD/ATi's first DX11 card would be able to compete with Nvidia's first DX11 card, untill ATi play catchup again.

Now if it'll have 512-bit bus (i sincerely doubt it), then it'll be a proper monster XD

(512-bit + GDDR5 = :eek:)

why would you doubt that? It's more than double the card of the current GT200, there is no way they would leave it to have a 256bit bus, so that it can have amost the same transfer rate as the current generation.

Wow I'm so glad I didn't hurry up!
I been really holding myself not to get a GTX295 and decent PSU for my desktop....

Q4 is just perfect for me - I'll be using the laptop mainly till mid-October.
Then I'll buy the GT(X?)300 and a car battery ehh PSU.

Wonder what the cost would be? And whether I should be spending so much..... I've saved enough for a GTX295 and PSU now.... so by October I'd have saved more...:rolleyes:

its be known for some time that it will be 2gigs of 512 bit GDDR5

ohhh dear this might just make ati have to step it up a gear with a new architecture.

I was thinking they'd go 384-bit (like 8800) to keep the cost down... it'll be expensive, that's for sure

Nice pack to play with. I betcha though that ATI will retaliate with perhaps 1000+ stream processors.

Or hopefully a new architecture that is better than the current.

I'm thinking I'll have to save up and get two of these just for that reason. All genetic diseases will cry out in unison when these things start folding. Or maybe that would be capacitor whine. I dunno, but do want.

When ati releases their 5xxx series I expect these to drop in price and buck to have a brand new folding farm.

That is if they don't need an incredibly powerful PSU to run, I think he may be going for power efficiency with his folding farm, his electricity bills must be through the roof.

Hey, I'm looking forward to this time next year, when I can get one at a reasonable price, like my recent GTX 285. :)

all i can say is i hope my card reatains value
i might get a new card then none of this 3 month i needs to get the version of my card with 20 more shaders and a 5% oc crap

February march time is when you need to get them not at release, christmas cash allows me to get a card then

The GTX 280 and 285 already use a 512bit bus. and the GTX 260/265's use a 448bit bus.

Why would nvidia want to keep costs down on their new flagship card? They'd want to go all out to throw the gauntlet down to ATI.

I thought that as well they would launch a supercard, that may be stupidly priced, just to crush AMD in the fight for top dog. However I want to see just how many the "stream processors/shaders AMD stick on there next model. To be honest I think this is just a retaliatory press release to keep the nVidians happy that they are going to have to wait an extra month or two for the next wave of cards.

Q4 will be a summer release.

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.

lol
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.
