There will be some lower TDP versions of this core with graphics but if you are looking for top performance it will have to come from this 18W part.
As we said many times before, Ontario comes powered by Bobcat, AMD's new core that will compete against Atom in single or dual-core versions. However, unlike the Atom, it will pack quite powerful graphics.
We are not aware of any clock speeds at this time, but we do know that this is exclusively a TSMC processor as AMD's belowed Globalfoundries doesn't want to play with 40nm and will only develop the 28nm bulk process.
This dual-core Ontario with graphics will also target notebook, embeded and SFF markets and let's not forget that this platform supports DDR3 memory. This version of Ontario is expected in 2011.
