Well I'm totally confused. When I first read about these cards a few weeks ago, I didn't know what to expect from these cards because I couldn't understand what to expect from a specific model.
Is the 6870 a 5870 replacement?
Well, no.. Read on..
Now for the people who are interested in the new 6xxx series, I've tried to do my best in compiling bits of information that I could gather from the internet.
Firstly, The Name Change:
From the information that I've been able to gather, TSMC, ATI's fabrication plant was unable to deliver cards based on the 32nm manufacturing technology. Now the 32nm would have allowed ATI to reduce the cost per GPU die while achieving higher clock speeds and lowering power consumption. What ATI have gone ahead and done is continuing to manufacture the 5700 series cards while renaming this to the new 6800 series.

Allright, So first we have the 6800 series cards. 6870 and the 6850.
These cards are based on the Barts core that we saw in the 5700 series.
In the 6900 Series, We've got 6970 and the 6950.

If you had the money, Would you buy an ATI 6-series card or would you buy a nVidia 5 series?
Good info !
ReplyDeleteAccording to AMD, 6950,6970 and 6990 have "Dual advanced programmable hardware tessellation units". and I believe it will perform well in heavy tessellated future games than previous 5xxx cards.
