Biostar spilled the beans on its support website and the leak was picked up by CPU World. The B-series chips will come in three flavours, the A4-6300B, A6-6400B and A10-6800B. The A10-6800B has a 100W TDP and it is clocked at 4.1GHz. The A4-6300B and A6-6400B are 65W chips clocked at 3.7GHz and 3.9GHz respectively.
Of course, we are talking about B-series chips and you shouldn’t expect to see them in any store. They are reserved solely for the OEM gang.
