Overview The P5 Pentium is the first superscalar x86 processor, meaning it was often able to execute two instructions at the same time. Some techniques used to implement this were based on the earlier superscalar Intel i960 CA (1989), while other details were invented exclusively for the P5 design. Large parts were also copied from the i386 or i486, especially the strategies used to cope with the complicated x86 encodings in a pipelined fashion.as compared to a simple RISC processor like the i960. Just like the i486, the Pentium used both an optimized microcode system and RISC-like techniques, depending on the particular instruction, or part of instruction. The dual integer pipeline design is something that had been argued being impossible to implement for a CISC instruction set, by certain academics and RISC competitors.
