Slot A

The slot A is a CPU slot for AMD Athlon processors in the K7 generation. With the introduction of the Athlon, the transition from the base to the slot was necessary because the processor core and the cache memory were separate chips on a common circuit board as with the Pentium II and Xeon processors from Intel.

The slot A is mechanically, but not electrically compatible with the slot 1; in this way could the hardware manufacturer for their Athlon motherboards from the outset available in large quantities components for the slot to fall back and take over the board layout of their slot-1 boards with relatively minor changes. Together with the slot A, the EV6 bus protocol of the DEC Alpha processor was adopted for the Athlon. This introduction of a market leader Intel incompatible socket and the protocol was initially considered as economically risky.

The Slot A was soon replaced by Socket A because AMD could unite cache and processor core on one die soon. In the relatively short time there were only two chipsets for this socket, the AMD 750 Irongate and the VIA KX133.
