AMD doesn't plans to abandon the single-core market. In Q3 it plans to introduce a CPU codenamed Sargas, and this is AMD's first and only 45nm single-core desktop CPU planned for 2009.

This CPU should replace the long overdue Sempron LE1300 and LE1250, as well as Athlon LE1660 and LE1640, all 45W CPUs.

The new 45nm Sargas based CPU will be branded Sempron 140 and this particular one should work at 2.7GHz. It has a planned TDP of 45W and total of 1MB cache.

This will be the first AM3 based single-core and it will support DDR3 1066 which definitely means that this CPU originates from the K10.5 generation of new 45nm CPUs. We still don’t know if this is a harvested dual-core 45nm Regor, or a native single-core CPU, but we would suggest that for the price sake, it better be a native single-core.
