AMD: R7xx Speculation

R700 is ATI's multichip, but at this time it looks that there won’t be four or six cores on the same die. Our sources have confirmed that we can hope for two cores on the same die.

Anything more than that would be too big for the current generation. We learned that R700 is a 45nm chip, but you cannot do miracles with this process.

The future of both R680 and R700 heavily depends on the new CrossfireX driver and we have some high expectations from this one.
 
RV770 meantioned in Mac and Linux drivers?

R700 Will Use 45nm Process
We learn from chiphell.com that AMD ATI next flagship R700 GPU will use 45nm process to produce. We don’t if TSMC will still produce R700 graphics chip for AMD and ATI, because some media previously report AMD could produce GPU using its own Fab located in New York State, US.

But judging from TSMC 45nm Production press issued at 2006/5/22, we can expect TSMC will continue to produce GPUs for AMD/ATI, and R700 will use 45nm process from TSMC. TSMC actually start 45nm production in last September, to produce low power chips for its fabless customers.

TSMC's 45nm process is a 10-metal-layer technology, with gate lengths said to be down to 26nm. The process itself is equipped with copper interconnects, strained silicon, triple-gate oxide and a second-generation low-k dielectric film. In addition, the company is expected to insert 193nm immersion lithography tools for production at 45nm. TSMC is reportedly using 193nm immersion scanners from ASML Holding NV of the Netherlands.

We expect 45nm process will shrink the chip area 40% smaller than 65nm process, which could do great do 4 cores R700 a great favor.

On the ramification of R700, we heard that AMD and ATI will introduce R770 or in name of RV770 after R700 introduction. On the GPU architecture, we heard there’s no much difference between RV670 and R700/R770.

This can be a mainstream or performance GPU (maybe against G96), hopefully rv770 based cards not 128bit wonders.

RVx70 is supposed to be fastest performance-part. So i think it could be RV670s refresh and will come in May (remember of the planed 6-month-cycle for perf. and high-end). Maybe it will also base of R780/R770 - dual-gpu-SKU...

Yeah like rv570/rv670.
Its can be great when they not wasting they resources/time to release highend first and come out with a performance GPU first in early/mid Q2.
 
4 Z-testers per ROP, TUs with 8TA/TFs, shader-domain with >1.2GHz and maybe 45nm process and we would have a very nice refresh, imo.

The RX780 was renamed to AMD 770 recently. I guess this is what we're looking at.
 
AMD RV770 ES

Single slot, single chip? By looking at RV670 board pics, however, it seems the two dies are identical in size, so I have the suspect this could be an RV 670 ES.
