With a bandwidth of just 15.76GB/s, the A10-7850K has considerably less bandwidth to work with than say the Core i3-4130, but it's virtually identical to what we saw from the A8-7600 and the A10-6800K before that.

The A10-7850K's cache bandwidth is slightly faster than the A8-7600, largely due to the increase in clock speed, though it's still at a disadvantage compared to the Core i3-4130.
