X-bit Labs reports AMD's Athlon II, Phenom II and Sempron lineups will reach the end of their lives in Q4 2011.
As reported earlier this year, AMD has very aggressive transition plan to new desktop families of products - A-series accelerated processing units and FX-series central processing units - made using 32nm silicon-on-insulator process technology from current-gen chips in AM3 form-factor made using older process technologies and based on older micro-architectures. As a result of such transition, AMD chips will no longer have product brand-names (Athlon, Phenom, Sempron, etc.), but will carry A-series, E-series or FX-series product names.
AMD recently notified its partners that the last orders on Athlon II, Phenom II and Sempron central processing units are due in Q4 2011. After that the company will not accept any new orders on those chips and will only conduct final shipments for a quarter or two. Effectively, the processors will gradually disappear from the market.
