Rumors of RV790 have been circulating since the start of the month when the first story popped up. Since then we have heard nothing that confirms the existence of the chip. Speculations have mainly been about what the name would be, Radeon HD 4890 being the most popular, and the specifications where the most common suggestion is that AMD will add two SIMD units to bring up the shader total to 960 and the texture units to 48. Others suggest a simple frequency boost but that would hardly justify a new chip. Still, we haven’t heard much that would confirm it’s existence so don’t get your hopes up too much.
