| - | In the x86 family first processor with two paths of execution was the Pentium with U and V pipelines. Modern x64 processors like i7 implement six execution units. Not all execution units have the same functionality. For example, in the i7 processor, every execution unit has different possibilities, | + | In the x86 family first processor with two paths of execution was the Pentium with two execution units called |

| For each physical core, the operating system defines two logical processor cores and shares the load between them when possible. The hyperthreading technology uses a superscalar architecture to increase the number of instructions that operate in parallel in the pipeline on separate data.
