The Palermo core introduced the 64-bit instructions to the Sempron family. However, there are Sempron processors based on this core that don’t have this instruction set enabled. The CPUs based on the Palermo core that have the 64-bit extensions use the letters ”BX“ as the two last letters on the CPU OPN.

Another feature introduced on Palermo core is the SSE3 instruction set, not available on Sempron processors based on previous core (Paris, based on 130 nm technology).
