Abstract :
Carrizo (CZ, Fig. 4.8.7) is AMD´s next-generation mobile performance accelerated processing unit (APU), which includes four Excavator (XV) processor cores and eight Radeon™ graphics core next (GCN) cores, implemented in a 28nm HKMG planar dual-oxide FET technology featuring 3 Vts of thin-oxide devices and 12 layers of Cu-based metallization. This 28nm technology is a density-focused version of the 28nm technology used by Steamroller (SR) [1] featuring eight 1× metals for dense routing, one 2× and one 4× for low-RC routing and two 16x metals for power distribution.
