The Carrizo SoC, using Excavator cores, was touted in the press as being the biggest upgrade to the base Bulldozer design since the introduction of Bulldozer itself. This was as a result of new high-density silicon libraries, a new voltage/frequency response unit based on internal sensor data, a redesign of the metal stack to afford high density, improvements to caches and scheduling, improved video units for 4K decode, and a mobile-driven focus for the platform. Today AMD is launching the second version of Excavator, based on an updated core, in two forms: Stoney Ridge for entry level notebooks and Bristol Ridge for mainstream devices.
