Rumored to be, the RV870 variants appear in 5. In this case, each GPU 800 to 970 MHz clock. We fall back on GDDR5 memory, which in various speeds up to 5GHz applies.
Models:
HD5850
HD5870
HD5870X2
HD5850X2
HD5890
The HD5890 is the first DualGPU Map of the World, where two cores are on a The! The chip for the HD5890 is manufactured in 32nm. The production will be held in Dresden and the end of the 3rd quarter of the 2009th Within just 7 months, the 32nm process is introduced. The other chips will continue in the new 40nm TSMC produced. DIe HD5850 and HD5870 will both have a 512bit wide memory interface feature. The X2 variants are, however, continue with a 256bit wide memory interface must survive, so the cost does not explode. The HD5890 is also equipped with a 512bit wide memory interface, and should be reduced by the manufacturing process and higher clock speed, consume less power, but faster than the X2 version.
Features all RV870 are DX11, OpenCL and MCM. The computing power per card is at 1.5 to 2 TFlops. The computing power of the HD5890 has not been commented on, I guess between 2.2 to 2.5 TFlops. The "The area is subject to 205mm ².
