Intel Pentium Pro

Historia

The Pentium Pro is a sixth-generation x86 architecture microprocessor by Intel originally intended to replace the original Pentium in a full range of applications, but later reduced to a more narrow role as a server and high-end desktop chip. It was introduced using an enormous rectangular Socket 8 form factor in November 1995. Intel has since discontinued it in favor of the newer high-end Xeon processor lines. Despite the name, the Pentium Pro is actually quite different from Intels earlier Pentium processor, being based on the then-new P6 core (which in a modified form would later be used for the Pentium II, Pentium III and Pentium M). The P6 core features out-of-order execution, speculative execution, and an additional pipe for simple instructions. Intel called its 586 processor Pentium because a US court ruled that you cant trademark a number.
