AMD Kaveri APU Architecture Overview

Llano put K10 CPU cores and a Radeon HD 6000 series GPU on the same die and introduced us to the FM1 socket. The Fusion project was then reformed as the Heterogeneous Systems Architecture (HSA). After Llano came Trinity, the second generation of APUs featuring Piledriver CPU cores and a Radeon HD 7000 series GPU. Trinity also introduced the FM2 socket. The third generation of AMD APUs, codenamed Richland, was more of a revamping of Trinity, and stuck with Piledriver CPU cores (turbocharged) and upgraded the GPU to a Radeon HD 8000 series.
