With the AMD Sempron based on the K7 architecture , AMD continued the path started with the AMD Duron in 2004 to offer processors in the low-price segment under its own brand name. At the same time, new AMD Sempron processors based on the K8 architecture were presented, which over time replaced Semprons based on the K7 architecture.

Technical

The AMD Semprons have a lower clocked front side bus and are usually only available with lower clock frequencies than the corresponding AMD Athlon XPs . This limits the performance of these CPUs, but the lower production costs also reduce the sales price.

The processor cores are identical to the cores of the faster Athlon XP processors.
