The NEXT LAST R600 Rumours & Speculation Thread

http://forum.beyond3d.com/showpost.php?p=976886&postcount=3083

thats an XTX right there with the full gig of ram, nobody seemed to care though.

 

I am not referring to a 1024MB single card higher clocked XTX, but rather two 512MB XT Crossfire cards positioned to fight the GTX/Ultra. Clearly, the Crossfire would outperform the GTX/Ultra, with better IQ too.

 

aye.

Take a good look at DT's XTX and notice where the power connectors are. Then take a good look at this XTX sugar provided.

 

yea but again though you and a few others are swinging the conversation over to how great it is via price wars, this isnt exactly what i and quite a few others care about, we want to know who has the better architecture. What exactly makes up the R600 and so on. I dont really care if they do a 2 for 1 or give cards away for free for that matter, it doesnt mean the cards themselves are better, which is what i and i believe quite a few others are interested in finding out. If waiting an additional 6 months only got AMD/ATi to do some strong pricing moves and the performance itself is lackluster, well then thats pretty boring.

 

But would it work for all games?

 

That's not what the sorce for those pictures says: Radeon HD 2900 XT显卡的最终工作频率定在740/825MHz（核心/显存）。

 

True, but you know...Occam's razor and all that.

 

Yeah, a 512-bit bus with 32-bit devices always requires 16 chips.

That's XT, having 16 memchips is required for their 512bit membus anyway.

 

Ye but that card looks bigger than 9.5" and you can clearly see the extra memory on the back(1024MB) so it's not an XT.

EDIT: LOL, both Jawed AND Kaotic beat me to it...

 

I thought it was 8x64?

 

Hmmmm, I wonder if this is him hinting at a 7950 GX2-ish setup for R600. A dual GPU 2xR600 single card (2 boards ala 7950 GX2?) setup to position against the 8800 GTX?

Personally I don't like the thought of this, but that quote sure does hint at it rather strongly IMO.

My power supply just pissed it's self.

 

I think powering and cooling a board with 2 R600s and 32 RAM chips would be quite a challenge. With design costs thrown in, it would probably be easier and cheaper to just go with 2 cards.

 

I never said anything about R600 being a "better" architecture than G80. How could one know that without having the cards on hand for extensive testing? I'm sure that both architectures have strong points and weak points in comparison to one another.

Being able to offer a high performance 1024MB total RAM crossfire solution (where NVIDIA right now can only offer 1280MB or 1536MB total RAM on GTS and GTX) is certainly a notable price-to-performance advantage for ATI in terms of cost of RAM, and that is tied to the fact that their card also uses a 512 bit bus. I said weeks ago that NVIDIA would need a 512 bit bus in order to better compete on a cost basis (in terms of on-board RAM cost).

This is a rumors and speculation thread on R600. I would think it would be relevant to talk about what R600 offerings they would position against NVIDIA. It's alot easier to speculate about that vs speculating on the architecture of a card that very few have had a chance to test (and those people are under NDA).

 

It's in Chinese. That should do it, I believe it

 

I think the rumour is that the memory controller is configured as 8x64. But that could mean two modules per controller - not necessarily 64-bit modules.

 

R5xx introduced the 32-bit per channel memory controller. Why would ATI go backwards?

Plus, these memory chips are 32-bit. Look at 8800GTX, it takes 12 chips to provide its 384-bit bus. It merely gangs pairs of chips to create 64-bit memory channels.

GDDR3/4/5 only come in x32 configuration and gDDR2 comes in only x16 configuration.
