The Excavator-based APU for mainstream applications is called Carrizo and was released in 2015. The Carrizo APU is designed to be HSA 1.0 compliant. An Excavator-based APU and CPU variant named Toronto for server and enterprise markets was also produced.
Excavator was the final revision of the "Bulldozer" family, with two new microarchitectures replacing Excavator a year later. Excavator was succeeded by the x86-64 Zen architecture in early 2017.
