The new cards are expected to support switchable graphics and continue pushing current technology features such as Eyefinity and H3D stereo 3D gaming. There are reports that AMD are planning to launch four different GPUs based on the 28nm version of the VLIW4 architecture and will use them in three different series: the Radeon HD 7800, HD 7600 and HD 7500. These GPUs will sport between 768 and 1536 stream processors as well as using GDDR5 memory.
