The Intel Pentium Pro Processor

 

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 Intel's 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.

Comment by MoonKnight (moonknightus[at]yahoo.com): The Pentium Pro was only a partial success for Intel. While it excelled in the server market, it failed as a desktop platform. This was for two reasons: (1) At the time of its introduction, most users ran 16-bit code and the P-Pro couldn't even keep up with the previous generation (Pentium) chips in this area. And (2) the Pentium Pro was excessively expensive. This was partially due to the fact that the L2 Cache had to be wired into the CPU package before either the CPU or the Cache could be tested. If one failed, they both had to be thrown away regardless of whether the other was good or not. Fortunately for Intel, the P-Pro core went on to success in the original Celerons, the Pentium II and the Pentium III. add comment
