Nordichardware wants to have learned, that the RV870, which is said to be a shrink of the RV770, runs by the codename "Lil Dragon”. This could be a reference to the new 40 nm structure or the possible performance. The performance per watt is said to be doubled, the overall performance is said to be 20 percent higher if compared to the RV770 and the power consumption is said to have decreased a lot.
Furthermore the RV870 is supposed to have 960 shaders (192 x 5), 48 TMUs and 24 ROPs. The power consumption is said to be 150 watt and AMD is supposed to stick with DX 10.1.
