The PPU is part of the PPE, the SPU is part of the SPE. The SPEs are more than just processor cores, the SPUs are full processors and the SPEs as a whole act as tiny systems on a chip within which the SPU acts as a CPU. This design is where a lot of the potential originates from (being able to perform tasks more independently and asynchronously using dedicated memory as fast as cache operates and high internal bandwidth for communication between the different parts of the chip).
