AMD's Trinity : An HTPC Perspective
 

Intel started the trend of integrating a GPU along with the CPU in the processor package with Clarkdale / Arrandale. The GPU moved to the die itself in Sandy Bridge. Despite having a much more powerful GPUs at its disposal (from the ATI acquisition), AMD was a little late in getting to the CPU - GPU party. Their first full endeavour, the Llano APU (we're skipping Brazos / Zacate / Ontario as it was more of a netbook/nettop part), released towards the end of Q2 2011. The mobile version of the next generation APUs, Trinity, was launched in May 2012.
