P6
Updated: 10/01/2023 by Computer Hope
Launched in November 1995, P6 (also called i686) was a microarchitecture that came directly after the original Intel Pentium processor. As the name would suggest, the P6 core was the sixth generation of microprocessors in Intel's x86 line. The first implementation of P6 was with the Pentium Pro processor, but it was also used with the Pentium II and Pentium III. The microarchitecture was succeeded by the NetBurst with the Pentium IV, but found use in the Pentium M series.
The P6 was a significant Intel design that featured innovations like superscalar, out-of-order, dynamic execution, and multiple pipelines. P6 processors also improved cache hierarchies and introduced power management for better energy efficiency.
