Editing Slot 1 (section)

== History ==
Historically, there are three platforms for the Intel [[P6 (microarchitecture)|P6]] CPUs: Socket 8, Slot 1 and Socket 370.

Slot 1 is a successor to [[Socket 8]]. While the Socket 8 CPUs (Pentium Pro) directly had the L2-cache embedded into the CPU, it is located (outside of the core) on a circuit board shared with the core itself. The exception is later Slot 1 CPUs with the [[Coppermine (microprocessor)|Coppermine]] core which have the L2-cache embedded into the die.

In the beginning of 2000, around the time the Coppermine Pentium III CPUs with [[Flip-chip pin grid array|FC-PGA]] housing were already commonplace, Slot 1 was being gradually phased out in favor of [[Socket 370]], well after Intel started to offer both Socket 370 and Slot 1 CPUs at the same time since late 1998. Socket 370 was initially made for low-cost Celeron processors starting with the [[Celeron#Mendocino|Mendocino]] Celerons, while Slot 1 was thought of as a platform for the more expensive Pentium II and early Pentium III models. Both cache and core were embedded into the die.

Slot 1 also obsoleted the old [[Socket 7]] as the standard platform for home users, at least regarding Intel. After superseding the Intel [[P5 (microarchitecture)|P5]] [[Pentium MMX]] CPU in the late 1990s, Intel had completely left the Socket 7 market.
