AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors and normal CPUs. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core.
The Excavator-based APU for mainstream applications is called Carrizo and was released in 2015.[3][4] The Carrizo APU is designed to be HSA 1.0 compliant.[5] An Excavator-based APU and CPU variant named Toronto for server and enterprise markets was also produced.[6]
Excavator was the final revision of the "Bulldozer" family, with two new microarchitectures replacing Excavator a year later.[7][8] Excavator was succeeded by the x86-64 Zen architecture in early 2017.[9][10]
