Getting very much confused about one thing. I saw that AMD's Kaveri series got 3 types cpu. A10 7850K, A10 7700K,A8 7600. The thing is that there are 4 cores in each processor but the computing cores are 12 to 10. 4 cpu and 8/6 gpu. Whats this? How does these 12/10 computing cores work in these 4 main cores? Im so baffled about these 'two' types of cores.
