AMD's followup GPU to Cayman, also known as GCN ("Graphics Core Next") and targeted for release alongside Bulldozer late in 2011. Southern Islands will depart from VLIW for the first time since the R300 (Radeon 9700), moving to 256-bit SIMD (at the same length as YMM registers, these might be suitable for AVX instructions).
