P55C
From Wikipedia, the free encyclopedia
The Intel Corporations P55C Pentium processor is a fifth generation processor developed in 1997.
The primary differences between the P55C and its predecessors is the incorporation of MMX technology which was designed to boost performance and increase average I/O speeds from 20% with non MMX compliant software to upwards of 70% while running MMX compliant and designed software packages.
While the P55C is compatible with the common Socket 7 motherboard configuration the voltage requirements for powering the chip differ from the standard Socket 7 specifications. Due to certain manufacturers not preparing for the introduction of MMX technology most motherboards manufactured for Socket 7 previous to the establishment of the P55C standard are not compliant with the dual intensity required for proper operation of this chip. The Intel Corporation temporarily manufactured a conversion kit called the Overdrive that was designed to correct this lack of planning on the motherboard manufacturers part.
The P55C was designed in three models incorporating a 166, 200 and 233[MHz]. This chip was the primary competition for the AMD K6 and the Cyrix 6x86MX processor and was the configuration sold until Intel released the Pentium II.
