In a rather interesting presentation, Gregg Bartlett, Sr. VP of Technology and Integration Engineering at Globalfoundries, just showed a slide with AMD’s upcoming Trinity APU, the successor of current Llano parts.

As expected, AMD’s next generation AMD A series APU will be based on a new Piledriver core architecture, or should we say Bulldozer. It will include a Radeon HD 7000 series graphics core, something that we still expect to see launch by Q4 2011.

AMD expects Trinity to be up to 50 percent faster than Llano, which is a pretty significant leap forward, since both chips are 32nm parts and they are roughly the same size. In other words, Piledriver should deliver vastly superior performance per transistor compared to Llano.

Trinity is also a part of Comal and Virgo mobile platforms and the performance boost should come in quite handy in the mobile segments. After all, Trinity will stick to the same 32nm process as Llano, but AMD will squeeze a bit more muscle in the same thermal envelope.

Availability is schedule 2012, and we didn’t get any better date than that. It is interesting that it is not a 28nm design, as Intel as we have repeated reportedly starts selling 22nm chips by April 2012. However, AMD will use 28nm for upcoming Krishna parts, set to replace the 40nm Bobcat core early next year.
