AMD (AMD +3.8%) gains after officially launching 4 desktop processors based on its delayed Trinity architecture. The chips are somewhat power-hungry, but also aggressively priced ($53-$122) relative to Intel's (NASDAQ:INTC) low-end Ivy Bridge parts, evidence AMD is willing to sacrifice margins to keep its market share from falling further. Reviews indicate only a modest CPU performance gain over the prior-gen Llano architecture (Intel maintains an edge here), but a healthy increase in graphics performance. (previous)
