For anyone tracking AMD’s family of Accelerated Processing Units (APUs), the last generation Carrizo was launched back in the middle of 2015. This was based on the fourth iteration of the Bulldozer module design (the cores are codenamed Excavator), focused entirely on notebooks at a 15-35W power window. Today marks the pre-announcement of the 2016 line, Bristol Ridge, for notebooks.
The main difference between Bristol Ridge and Carrizo is the implementation of a DDR4 memory controller, along with minor microarchitecture manufacturing tweaks. We’ve already seen Carrizo/Excavator under DDR4 in the embedded space, and AMD is claiming that this latest generation of Bristol Ridge offers up to at 50% CPU improvement over Kaveri, launched in 2014, and Bristol Ridge is some 10% over Carrizo due to the new memory support.
