Excavator is a microarchitecture under development by AMD to succeed Steamroller. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-based core. The Excavator based APU will be codenamed Carrizo, scheduled for a 2015 release.[2][3] Excavator is expected to support new instructions such as AVX2, BMI2 and RDRAND.[4] Excavator is also expected to come with DDR3 and DDR4 memory controllers, currently not known if on the same die or mutually exclusive.[5]

Excavator will be designed using High Density (AKA "thin") Libraries normally used for GPUS, delivering a 30 percent increase in energy efficiency.[6] Excavator has been confirmed to be AMD's last microarchitecture of the Bulldozer-family with an all new microarchitecture following Excavator a year later.[7]

Carrizo APUs will use Socket FM2+.[8]
