Intel Pentium Pro

The Intel Pentium Pro was released in 1995 while the original Pentium line was still active, and introduced the P6 architecture. Later and even current x86 processors are based on the P6 architecture, with significant changes integrated over the years. Pentium Pros were first made with a 500 nm process and incorporated 5.5 millions transistors.

They were available as 150, 167, 180 and 200 MHz parts, and 133 MHz prototypes exist, while 200 MHz models can often be overclocked to 233. This processor uses the Socket 8.

The Pentium Pro targeted the Server Market and was thus very expensive as are usually the Xeon Processors nowadays.
