What is a PPGA CPU?
i see some celerons that say that next to them on web pages.
what is PPGA?

PPGA is a socket 370 processor, sits on the mobo like the first pentiums and older processors did. I know there are adaptors that you can buy to convert it to fit into a slot 1 motherboard.

Below is a cut and paste from zdtv.com

A: There really is no difference in perfomance or architecture between a PPGA (Plastic Pin Grid Array)-- better known as Socket 370-- and an SEPP (Single Edge Pin Package)-- or Slot 1-- Celeron.


The Celeron is a Pentium II with a cache that's been either reduced and double clocked or removed entirely. The Celeron came in what is known as a SEPP, or Slot 1, form factor. The SEPP form factor placed the L2 cache and the CPU on a daughtercard, so the L2 cache could reside closer to the CPU die for better performance, instead of on the motherboard, where it resided in the Socket 7 form factor.


CPU technology advanced to a point where the L2 cache could be placed on the CPU die itself, which led to the PPGA, or Socket 370, form factor. By placing the L2 cache on the chip die, Intel could eliminate the Slot 1 CPU daughtercard system. This did two important things: First, it enabled a cheaper CPU fabrication process, and second, it increased the performance of the L2 cache.


Intel hopes to gradually transition its entire product line to the Socket 370 form factor, but some skeptics believe it's Intel's way of eliminating competition. Intel didn't bother to patent the Socket 5 or Socket 7 form factors, so rival CPU and chip set makers produced similar chips at lower prices by piggybacking on those technologies. When Intel moved to the Pentium II and the Slot 1 form factor, the company patented the design so no one else could produce Slot 1 compatible CPUs.


The competion pushed back, and came out with the Super Socket 7 and faster CPUs that rival Intel's. So Intel decided to move to back to the socket design because of the design's inherent performance qualities.


Since Intel is the dominant player in its field, any move it makes is likely to be followed by a majority of the industry, although less so than before. By switching to yet another form factor, Intel benefits not only from newer technology, but it can also shake its CPU rivals' market shares by giving them another Intel product to deal with and giving consumers another option.
