ATI's R600 has 64 real pipes

They are never like "well with Nvidia's move from the 7800 to the 7900 they are just keeping the pipes the same number" nope they said 32 pipes for the 7900. They didn't do that with the x1k series from ATI they didn't say well they are going from 16 pipes to 24 pipes" nope they said 32 pipes for the x1800 too. I swear they are a paid rumor mill.

Well they got pipe and pixel shaders confused there are 48 shaders in 1900 . I will say that r600 will at least have at least 64 shader units with a unified arch so there is no point of using pipelines to define cards anymore. The R600 will also have least GDDR4 at R580+ speeds.

I agree with the op, that article was quite a shocker! Of course pipe is a flexible word - so probably theinq has an arguement to use it. And as always it generates hits.

I don't mind the Inq but damn the person that wrote the thing should proof read it before they post it to the internet...

when is G80 coming out anyway.
i've heard all summer it'll arrive in spetember but so far nothing has been released.

Well, the G80 will still "supposedly" use traditional pipes and shaders. I have heard 32 traditional pipes and either 1 or 2 shader units per pipe. I have a feeling it will be 1 per pipe.

It actually almost seems believable, since the R600's "pipe" will have to make a choice between pixel shading or vertex shading. Thus, at any given point, it could have 48 pipes doing PS, and the other 16 doing VS, much like R580 does with its fixed 1:3 pipe today. A bit disappointing to me, actually.

Bingo. We have a winner

I can believe 64 pipes. But they won't be dedicated to either function.

These are the same guys that say that the R600's core will reach 1GHz. Yeah right! :laugh:

ATI's R600 reaches for 1000MHz clock

Nice, Kinda hard to hear after I just bought a X1900XT recently O well my X1900XT should last me until DX-10 cards as my X800XL wasn't going to make it :-D Technology is so Fast it's hard to have to have the latest thing for too long.

I really hope ATi wipes the floor with Nvidia not to be too biased just because alot of people thought the G80 was going to destroy ATi and unless they bought AMD ATi was going to be in trouble.

I have come to trust T INQ a bit more than before because a lot of what they've said has come true.

G80 will be more than 1~2 shader per pipe. The technological side of things based on recent/older NV patents suggest this card will be quite a leap from NV47/G7x architecture.

Not to mention that in the lastest 91.45 drivers, there are more AA settings such as 2xS, 4xS, 6xS, 8xS. Im thinking that it has something to do with G80 and its allegded new AA engine.

Then there are rumours that G80 if half unified. That there is a seperate number of geometrical shaders but unified pixel/vertex shaders.

R600 on the otherhand can either address its rumoured 64 unfied shaders to pixel shader,vertex shader, and geometry shader. If they can pull this off, it means that the avg fps will stay almost constant instead of fps drops.

Both will use GDDR4 for sure, but 512bit bus might be a possiblity. The price of these things would rise through the roof. Not to mention the increase in heat!

R600 wont be that big of a leap because ATi aint stupid to throw away their R580/R520 architecture design like that. (mustve costed them a fortune but anyhow) I think there will be lots of architectural similiarities between the R600 and the R580/R520. They will add a few things here and there, like dongless crossfire, incorporating the DX10 and unified shaders to the already powerful R580 architecture while tweaking here and there. The memory controller will be there i suppose.

Those AA settings are ancient.
