AMD Rx 400 series Ellesmere and Baffin GPUs taped out

Rumor site WCCF Tech claims it received confirmation that AMD has taped out two of its next-generation Radeon Rx 400 series "Arctic Islands" GPUs; the Ellesmere and Baffin designs. Both chips will enter production on a FinFET process next year but now a lot of further information is known.

If the information is correct, Ellesmere will target the performance market, while Baffin seems geared towards the mainstream market:

AMD has also managed to secure a major OEM design win with both “Ellesmere” and “Baffin” GPUs a source with knowledge of AMD’s roadmap confirmed to WCCFTech. Greenland will be AMD’s next generation flagship GPU, while Ellesmere and Baffin will address the performance and mainstream segments of the market. The Arctic Islands family will debut with the three aforementioned GPUs in a variety of SKUs which will address the entire discrete GPU market top to bottom. We’ve seen this three GPU strategy before with AMD’s first 28nm GPUs code named “Southern Islands” in the form of the HD 7900 series, HD 7800 series and HD 7700 series.

Last week, AMD promised its next-gen GPUs will offer twice the performance/Watt than the current generation.
