The NEXT LAST R600 Rumours & Speculation Thread

Hi,

I'm surprised that no one picked up that the GDDR4 1GIG card seems to be underclocked. The original rumours spouted that the GDDR4 card(ala XTX?) would use 2.2(or 2200Mhz) yet these pics only show 2000Mhz.

Of course as someone mentioned, these are most probably developer cards thus why it only has 2000Mhz and is called XT.

HD2900XT GDDR4 OEM? (750/2000). Maybe the same version, like in DailyTech "preview"... (they call i XTX, but I think they are just wrong )

 

According to publicly leaked information, the processing is still done on the CPU. You know, just like what any modern integrated audio solution will do; these things leave all the major processing duty to the CPU. In the end, that kind of work is so minimalist is doesn't really matter. Some EAX effects (which neither R6xx nor 99% of integrated solutions support in practice anyway) *might* be a bit more expensive.

 

So, R600 would just have an integrated audio codec, similar to those in all over the mainboards?

 

If so, then the PCI-e should cope well.

Other sound cards usually work off PCI.

It will be nice to finally get rid of those sound + graphics IRQ conflicts anyway.

 

This should be from AMD's own papers:

 

I thought GDDR4 was supposed to be more efficient from an energy side of things, when compared to GDDR3, at the same clockspeeds? (I know 2.0 W is next to nothing anyway.. but still)

And the GPU TDP looks off too, both are estimated at 750-800, same voltages etc.. just one is GDDR3, one is GDDR4, and the latter has a TDP 20 W higher?

Maybe i'm just being oblivious to the obvious though (i'll blame the hangover)

 

Ones 1024mb of GDDR4, and the others 512mb of GDDR3.

 

*goes and sits in the corner with his dunce hat*

 

Given that the DX9 version of that game is already easily one of the best looking games available today, the DX10 version if the difference is as big as you say it is must be out of this world!

I may even pick it up. Didn't have much interest in this game but tried the demo recently and it was supprisingly very good. And like I mentioned, the graphics are stunning!

 

What you quoted is not an XTX and nor is it retail, so you shouldn't worry.

 

Pre-order on Amazon. $448.99

Pre orders attempting to rip off as usual ?

 

How does that change GPU TDP? And why does board TDP stay the same?

 

Because it's pulled out of someone's arse? Amazing huh what the internet can do with numbers..

225W doesn't stroke with the numbers of the GPU and memory. and TDP values are always represented as "typical" values under normal operation and not the maximum value. that would mean that under heavy benchmarking the card would draw.. what.. 50% more power than the 225W represented there?

EdiT: Oops wait.. if ATI follows AMD suit than the numbers there should be the maximum possible power draw, period. 8800GTX TDP is 185Watt so the whole world is going to melt with this one 40W lightbulb extra?

 

Hehe, I guess so

 

There are othere sources telling the same TDP data.

 

Do you seriously believe that R600 uses 20Watts more just because it works with GDDR4 instead of GDDR3.
I know the 1900XTX had a TDP of 90W officially, does anyone know the number of the 1950XTX?

 

Dont know how much 1024MB GDDR4 uses, but i saw a other document with the same data.
