AMD Unveils Carrizo APU With Excavator Core Architecture

When it was first announced, AMD detailed support for next generation Radeon Graphics (DX12, Mantle, and Dual Graphics support), H.265 decoding, full HSA 1.0 support, and ARM Trustzone compatibility. But perhaps one of the biggest advantages of Carrizo is the fact that the APU and Southbridge are now incorporated into the same die; not just two separates dies built into and MCM package.


This not only improves performance, but also allows the Southbridge to take advantage of the 28SHP process rather than older, more power-hungry 45nm or 65nm process nodes. In addition, the Excavator cores used in Carrizo have switched from a High Performance Library (HPL) to a High Density Library (HDL) design. This allows for a reduction in the die area taken up by the processing cores (23 percent, according to AMD). This allows Carrizo to pack in 29 percent more transistors (3.1 billion versus 2.3 billion in Kaveri) in a die size that is only marginally larger (250mm2 for Carrizo versus 245mm2 for Kaveri). When all is said and done, AMD is claiming a 5 percent IPC boost for Carrizo and a 40 percent overall reduction in power usage.

Excavator looks really good actually. Too little too late for AMD though.
