Macles reports AMD will introduce a dual-core C-60 chip in Q3 2011. This 9W TDP model will be clocked at 1GHz, it's almost identical to the C-50 but it will offer a 1.33GHz Turbo Core mode and Radeon HD 6290 graphics instead of HD 6250.
While the theoretical numbers are great, with an increase of 33% for the CPU and 44% for the GPU, I'm curious how this plays out in practice. Especially during tasks which are both CPU and GPU intensive. Does the C-60 "trade" TDP between CPU and GPU? What's certain is that one core can clock to maximum frequency when the other is idle. This alone is useful enough already, but questions about how this works in combination with the GPU are still to be answered.
