Since the House passed 100 to summarize it:

We all know that RV870 is a native dual-core, MEM share, TMU sharing, etc. These hardware innovations is just the beginning, or rather in addition to hardware of the new technology, RV870 brings us the updated software in-depth , for example, CrossFire mode, specifically can refer to the savage major technical paper, I did not explain the response to this (http://bbs.chiphell.com/viewthre ... & extra = page% 3D1)
RV870 by native dual-core hardware support, the biggest benefit is the CF model can be evolved from today's AFR for a more reasonable SFR (do not understand what AFR and SFR for us to look savage Great article,), SFR and thoroughly get rid of the PCI-E bandwidth bottlenecks leading to CF or SLI can not use the SFR of the constraints, CF no longer rely on driving on the optimization of 1 +1 is infinitely close to two and said, where everyone will be RV870 native dual-core architecture of the deep deep impress, at least in my case, native dual-core is my first time in years, felt playing card graphics technology, a major step forward.
Go back to Crysis on the results, in fact, the RV870's Crysis performance can be regarded as a strong reason why the bounds of reason, but it can be regarded as lucky, because to say whether it is before the CF or SLI, the efficiency of both in Crysis is not high, RV870 just drill the use of technology, this SFR loopholes and completed card crisis, the role of Terminator, but I hope that everyone calmly RV870 performance, in other CF or SLI more efficient GAME in, RV870 impossible to think about Crysis so lucky, though it in terms of the total, RV870 architecture as pioneered the use of dual-core technology, combined with the many part of the shared framework, the core DIE or the ratio of power consumption and performance will be the same Performance Products the highest, which is beyond doubt.

Lao Lao hastily said so much, would have wanted to test them on the RV870 article says, but I got fascinated by the RV870 architecture could not resist spraying a bit out, more content or waiting for me in the future release of the RV870 test, let us share the bar.
Quietly asked a small problem, AFR to SFR does not seem to call it evolution, can only be called after the performance to a certain extent the development of an inevitable trend of bar

CHIP has the original "Dual" Processor Unit, each PU contains 160 VLIW (vulgar understanding of the words Where there are two RV770 form a RV870), but certainly not in now with a simple package prices
Where CrossFireX decker SLI are AFR (cross-frame rendering), image processing, 2 GPU Where】 【rotation exchange working, efficiency relates to the driver to complete a few quick, the error can not compensate for delay
RV870 with generous SFR (split-frame rendering), image processing, professionals, all know that playing a three-color RGB images must be completed, SFR Where Through 1FPS on screen divided into a number of 8 * 8-32 * 32Pixel generous detailed map between the to carry out the same color with the nuclear deal as long as the Bandwidth咁sample is large enough, you can achieve the same RV770 generous GPUClock case is equal to +200% efficiency.
(SFR consumption on the heaviest Where Bandwidth, RV870XT will spend the world's fastest generous GDDR5)
The above messages are from the Mainland China's internal sources AMD

Praytell why the hell would ATI make a "native dual core"? That doesn't even make sense with GPUs. If they are going to CF two GPUs on one die, they would be better off just making it one GPU. It'd be faster with less overhead and wouldn't cost any more to manufacturer.
Basically instead of making a mega cores with 1600 SP you make two 800 SP cores on the same die with fast inter connects to support SFR. This way you can concentrate on refining process tech for the lower trans count 800 SP cores. It will not be as fast as a native 1600 SP chip but it will be easier to produce. And it appears that the cores share a single memory controller. So I guess instead of calling it dual core it may be better to call it dual shader mega clusters.
