An Introduction to AMD's Second-Gen Fusion Processors: Brazos 2.0

In this lovely month of June, AMD rolled out the successor to Zacate, Brazos 2.0. Not much is new in this release, merely higher speeds. The E1-1200 is meant to replace the E-300, bumping up the CPU speed by 100 MHz and the GPU by 12 MHz. For some reason AMD downgraded the memory controller in the E1-1200 to DDR3-1066 instead of DDR3-1333, like the E-300 had. The E-450 has been upgraded by the E2-1800, with a 50 MHz increase in the CPU clock. The GPU has been pushed up to 523 MHz without boost and 680 MHz with boost. These are 3 and 13% gains, respectively. AMD chose to keep the DDR3-1333 memory controller here. Overall, Brazos 2.0 is not much of an improvement, but if cost is not a factor, there's no reason to buy an older Zacate machine.
