Come 2011, and AMD is looking to give Intel its much awaited fightback at all market segments of consumer processors including the enthusiast-grade models. It will be made possible with AMD's new Bulldozer architecture, which gives the processor a much higher degree of inter-core integration, sharing of common components, higher instructions per clock-cycle, and Advanced Vector Extensions (AVX). AMD's Bulldozer "Zambezi" desktop chips will be reportedly available in two ultra high-end SKUs: the 8-core AMD Vision Black FX, and performance segment AMD Vision Ultimate FX. AMD suspended the use of "FX" identifier with its Phenom and Phenom II series processors, because it couldn't compete in higher-end market segments, and didn't want to dilute the "FX" identifier. It was replaced with "Black Edition" to help identify models with unlocked BClk multipliers. AMD's Vision Black FX processors will be competitive with Intel's highest-end processors, including Extreme Edition models.
