That is the official name

 

We finally figured out out the final specification of the chip that we called RV870 and the fact that AMD plans to call it Radeon HD 5870 doesn’t come as a big surprise. The chip works at 800MHz and has 1600 shaders, two times more than RV770 which indicates that the chip is two times faster than the year old RV770.

The chip has as many as 2.1 billion transistors and is more than twice the number the RV770 packs, which has 956 million transistors. The card uses GDDR5 memory clocked at 1.3GHz (5.2GHz in quad mode) and can provide more than 150GB/second bandwidth. The power of this card stays at 180W while in idle the power drops down to 27W, three times less than the 90W on 4870.

By a rough specification-based estimate, the Radeon HD 5870 could end up two times faster than the Radeon HD 4870 but realistically, you should expect the new card to be faster by about 60 percent across the board.
