Immediately after the announcement the prices for video cards based on RV670 chip will be adjusted in the range $ 149-199. But here the latest news speak that AMD will lower the default frequency for video chip based on RV670 . Lower prices for AMD in this case proved easier than higher frequency. As expected, the 55 nm process allow AMD to have some price reserve.
Today appeared information confirming the frequency and values for video Radeon HD 38xx:
- Radeon HD 3870-> 775/2400 MHz, 512 MB GDDR-4 memory , price from $ 199 to $ 229;
- Radeon HD 3850-> 668/1656 MHz, 256 MB or 512 MB GDDR-3 memory , price from $ 149 to $ 179.
Moreover, later may appear the Radeon HD 3870 versions with 1 GB GDDR4 memory , which will cost approximately $ 20-50 higher then the standard. In January 2008 will appear the Radeon graphics card HD 3870 X2, which brings on one PCB two video chip RV670.
RV670 based video card will be able to dynamically alter the frequency proportional to the core and memory load. Voltage of video core will change also dynamically.
