AMD Six-Core Thuban Shown At Cebit
 

We had a nice photo shoot with a working engineering model of AMD's upcoming Thuban six-core CPU. The upcoming Phenom II X6 Thuban is still in its early stages and AMD simply wanted to show that it works on AM3 motherboard. At this time the precise clocks or any info whatsoever haven't been disclosed.
