The Radeon HD 7000 series is more or less complete at this point, which means AMD is furiously working on the HD 8000 series.
We don't mean the GPUs previously found inside laptops though, since those are most likely rebrands of the 7000 series.
Instead, we are referring to the so-called Sea Islands graphics processing units.
Fudzilla says they will be available in early 2013, or at least during the second quarter. They will be designed on the 28nm manufacturing process, the same one used by HD 7000.
Until a while ago, it was hoped that the Radeon HD 8000 would make their appearance this year (2012), in the fourth quarter or even the third.
The company roadmap has gone through some changes since then, however, so now we have to wait for a few more months.
