Quote:
The R7xx family from ATI is slated for arrival this Spring and will apparently be a bit different from other generations of graphics cards. Ever since early 2006, the story has been that ATI will put the one billion transistor chip aside and instead go for a much more modular GPU, where one core could be used for the low-end cards. Two cores for the mid-range cards, and four to satisfy the high-end users. This could throw more than a few thumb rules out of whack though.

First of all, this could very well mean that the rumors of R7xx being made with a 45 nm process are true (translated source). Usually a high-end chip is made with the same process as the older mid-range GPU, and it's a lot easier to move from 65 nm to 55 nm than from 55 nm to 45 nm.


New cards should be out in the spring 2008. Will this be first multi core gpu?

It better be sth good, cause ATI just can't compare to Nvidia these days... Something tells me that it'll be the same as now...

Well, I'd guess multicore GPUs will be the same as multicore CPUs: You need devs to support multicore and take advantage of the cores. And we all know how multicore games really are (especially Crysis) Rolling Eyes

ati pfft

even if they get their hw right some day [i doubt] they will always have shitty drivers

I dont think its the same as cpus. Multi core gpus should work the same as one core gpu. Its not as same as sli because they wont work as master slave. All cores should work as one entity.

Depends on the architecture and how it's utilised. Prolly too early to say whether the extra cores will be used natively or more like previous multi-gpu solutions which have affectively been two boards on one card..

The 3870 is the best budget card around, and the 3850 is the best cheap card around.

The 8800GT doesn't have a low enough price point yet, you're underrating them..

That being said, this architecture will be shit and Nvidia will still blow them out of the water eventually.

It is to early but they cant make card that uses the same system as sli,which is master slave relationship. Multi core shares everything from bandwidth to memory while sli doesnt. It would be too hard to make drivers that would tell every core what to do with every game. It simply cant work like that. Anyway in 2-3 months we will have newgen of cards from Nvidia and Ati so we will see how this multi core gpus work. I hope that Ati has at least the same quality of multi cores as Nvidia.

I think we're talking about the high-end, not the mid-range, where AMD might have a lead.

And wtf is ATI doing in the title? It's AMD!

the 8800gt should be at a very similar price-point to the 3870 making it an obvious choice for direct comparison. It's unfortunate that due to supply problems vendors are increasing the price by at least 10% Sad Also worth considering there is a 256meg version of the card which falls well into the budget-performance price range. I'd disagree and say that either the 8800gt is the best budget card or that neither of them are budget cards in the first place..

I actually think now is a bad time to buy gfx as there will be a jump in power next year which is why we're seeing high-performance cards on the market at such prices..

I don't think this is possible given the size this thing has to be. If they want to sell low end cards to the specific demographic - they aren't going to have them buy a 12 inch card to fit in their tiny cases. That's just one point besides the other 50000 that make this an impossibility.

This is all just nonsense, dream on everybody! Laughing

This is the size of 8800gtx gpu. Its made in 90 nm manufacturing process. New gen cards are being made in 45nm. Oh and i dont see intels and amds cpus getting bigger because they have more cores.

No offense Nakitu, but why is it that every time I say something you misunderstand/misinterpret/twist it?

I'm not even gonna respond man it's starting to irritate me.

Have a good day. Very Happy

Size of PCB is not determined by size of GPU. You think that because of more cores it will be big while in fact more cores doesnt mean bigger card (PCB). Did i misunderstand/misinterpret/twist the thing you said?

Yes. I never associated the number of cores with the size of the PCB - you assumed that. I was reffering to something else in that article.

But besides that do you really think given the die shrink from the R600 to the R670 (Same size) they can manage to pull 4 cores out of their ass and keep the heat/size/complexity on a small scale? It's not happening, besides the fact that Dual core GPU's NEED to become readily available on the market before they can even attempt at a Quad.

You are defending something that does not exist - or at least exists as a rumor.

EDIT: Look at the 3870X2 pictures that were leaked, that things a absolute monster even at 55nm - and we are talking about 2 cores on one die. Not 4 - never the less 2 for the mainstream 8600GT/2600XT market. Again, not happening.

Ok my mistake i guess i assumed you were talking about size of gpu.
