There are so many different processors, and they all fit different motherboard type connectors... I for one get tired trawling round the www trying to put it all in order mentally, so i spent the whole day collecting data to make a list... Not definitive, but includes most of the processors we would use for digital audio, and a few oldies we won't probably use much anymore.

All this page is for is so that you can checkout a chip speed and what type of board connector it takes, and for newbies to show them the different socket TYPES and the chips that go with them.

For us PC-Audio people it all starts with the MMX pentium in the olde days... and from there we've had SLOT-1 for P2 & Celeron and AMD came with the SLOT-A for their early Athlon's... The SLOT-A looks like the SLOT-1, and is 'the SLOT-1 for Athlons'...

On both types (Intel slot-1 & AMD slot-a), the CPU sits on a board enclosed in a case with cooler, that looks like a video cassette... Intel pushed the 'Slot-1' & P2 & older P3 aside and went to the New P3 & Celerons on SOCKET 370 (a ZIF socket), easy to install chips into.... the AMD K7 Athlon & Duron moved to the Socket-A. - Now we are on the next gen of P4 & Athlon... up to and above 2ghz.... we have the Athlon & Duron on SOCKET-A and the P-4 on SOCKET-423 & SOCKET-478.
