Package numbers of AMD microprocessors

AMD package numbers are 5-digit numbers located in the lower left corner on the top of PGA packages. On 754-pin PGA packages this number is located in the center on the back of the package. Because this number describes the type of PGA package, and not the type of CPU die, its usefulness for chip identification is very limited. Still, knowing the package type it is possible to determine CPU family name and an some cases core name.

* Date range - dates in the date range are in format: "week number / year".

The data in table is based on sampling of relative big number of AMD microprocessors (more than 1,000 CPUs). It is possible that data for some or many package numbers is incomplete, that is for these package numbers the table doesn't show all possible CPU family names and core names.
