AMD launches Danube and Nile platform

May 12, 2010: It's been a busy week for AMD. Yesterday AMD added 6 new desktop Athlon II processors, and today they launched mainstream and ultrathin notebook platforms. Two microprocessor families shipped with these mobile platforms were rebranded - "Turion II Ultra" family was changed to "Phenom II", and "V Series" family replaced "Sempron Mobile". According to a footnote in AMD's press release, this year PC manufacturers are going to launch 109 laptops based on mainstream "Danube" platform, and 26 notebooks/netbooks based on ultrathin "Nile" platform.

New notebooks on upcoming AMD Danube platform

May 05, 2010: As was widely reported in December of last year, this month AMD will launch Danube platform with 12 new Phenom II and Athlon II mobile microprocessors. The new lineup consists of three quad-core, 2 triple-core, 6 dual-core and one single-core processor.
