The slot A is a CPU slot for AMD Athlon processors of K7 generation. With the introduction of the Athlon, the transition from the socket to the slot became necessary because, as with the Pentium II and Xeon processors from Intel, the processor core and the cache memory were separate chips on a common circuit board.
Slot A is mechanically, but not electrically, compatible with slot 1 ; In this way, hardware manufacturers for their Athlon mainboards were able to fall back on components available in large numbers for the slot right from the start and also adopt the board layouts of their slot 1 boards with comparatively few changes. Together with slot A, the EV6 bus protocol of the DEC Alpha processor was adopted for the Athlon . This introduction of a socket and protocol incompatible with the market leader Intel was initially viewed as economically risky.
The slot A was soon from Socket A replaced as soon AMD cache and processor core on a The could unite. In the relatively short time there were only two chipsets for this socket, the AMD 750 Irongate and the VIA KX133 .
