Introduction One of the Pentium Pro processor's primary goals was to significantly exceed the performance of the 100MHz Pentium processor while being manufactured on the same semiconductor process. Using the same process as a volume production processor practically assured that the Pentium Pro processor would be manufacturable, but it meant that Intel had to focus on an improved microarchitecture for ALL of the performance gains. This guided tour describes how multiple architectural techniques - some proven in mainframe computers, some propos ....
