Notes

Note 1: The Pentium Pro, Pentium II/III, and the Celerons based on them are essentially the same design with minor internal revisions and varying cache designs. Because of this, the same chipset can be used for Socket 8, Socket 370, Slot 1, or Slot 2 designs with any CPU in the P6 family. In practice however, newer chipset designs are usually only made for the newer processor packages, and older ones may not be updated to accommodate for recent package designs. In addition, certain chipsets may be implemented in motherboards with different processor packages, much like how the 440FX could be used either with a Socket 8 Pentium Pro or Slot 1 Pentium II. Socket 8 CPU socket was used exclusively with the Intel Pentium Pro and Pentium II OverDrive computer processors. ... Socket 370 is a common format of CPU socket first used by Intel for Celeron processors to replace the older Slot 1 CPU interface on personal computers. ... Slot 1 refers to the physical and electrical specification for the connector used by some of Intels microprocessors, including the Celeron, Pentium II and the Pentium III. Slot 1 was a departure from the square ZIF PGA/SPGA sockets used for the Pentium and earlier processors. ... Slot 2 refers to the physical and electrical specification for the 330-lead edge-connector used by some of Intels microprocessors, including the Pentium II and Pentium III. Slot 2 is intended for use in high end multi-processor workstations and servers. ... The P6 microarchitecture is the sixth generation x86 microprocessor architecture of Intel, released in 1995. ...
