AMD’s “Sea Islands” graphics card lineup is set to arrive as the Radeon HD 8000 series in the second quarter of 2013, according to supply chain sources talking to DigiTimes. The Taiwanese website says Southern Islands’s successor was originally scheduled to land by the end of the year, but was pushed back as AMD focuses on its ongoing business reorganization. Other reports had pegged the launch for Q1 next year, which would have been in line with this year’s retail launch of the Radeon HD 7970 in January.
