The PPU runs two [[Thread_(computing)|hardware threads]] simultaneously. The [[Processor register|main registers]] for code execution are duplicated, as are the exception and interrupt-handling registers, and several essential arrays and queues. They can generate exceptions simultaneously, and perform branch prediction on their individual branch histories. The execution engine and caches are not duplicated though - so it is still just a single-core design.<ref name="the-ppe" />
