Starting with the 300A, all Celerons have come equipped with 128KB of on-die Level 2 cache running at full CPU speed and communicating externally via a 66MHz bus, making them far more capable than their sluggish predecessors.
Somewhat confusingly, all Celeron processors from the 300A up until the 466MHz were available in two versions – the SEPP form factor or in a plastic pin grid array (PPGA) form factor. The former was regarded as the mainstream version – compatible with Intel’s existing Slot 1 architecture – while the latter was a proprietary Pin 370 socket, neither Socket 7 nor Slot 1.
The use of a socket, rather than a slot, gave more flexibility to motherboard designers as a socket has a smaller footprint as well as better heat dissipation characteristics. Consequently, it provided OEMs with more potential to lower system design costs. The 500MHz version was available in PPGA packaging only.
