Compared to Zambezi (Bulldozer FX CPU), Vishera is more like a refresh than a new launch. The Trinity APU that we reviewed a couple of weeks ago features a greater architectural change in both the CPU and the GPU. However, with Vishera we get a minor tweak of the CPU architecture (Piledriver) in conjunction with a higher clockspeed. This is not a bad thing because Piledriver has improved upon some of the weakness that Bulldozer showed. This, coupled with a higher operating clockspeed, means the Vishera CPU should offer some good performance enhancement over Zambezi."
