AMD will ditch the VLIW architecture that has been in use from HD2XXX series since 2007. The VLIW will be replaced by CU (Compute Unit) which is a completely new development that represents the culmination of 5 years of R&D. It is expected that the new Compute Unit (CU) will be used in next generation HD7XXX series of GPU's.

AMD is working on this new architecture for almost 5 years now and has the objective to simplify the programming model to convince up to developers to address the computing power offered by GPUs. It is also the first architecture have been influenced deeply by the integration of AMD and ATI in the project Fusion.
This architecture marks a significant break compared to current GPUs by getting rid of the VLIW model, based on the simultaneous execution of multiple independent instructions in favor of a scalar function in terms of the programmer. The front-end processors and controls the structure of the caches have also been completely redesigned to offer a compute mode more efficient and flexible and to deal effectively with multi-tasking will become increasingly important for GPUs.
