Intel 2

All Intel Celeron processors in PPGA package were based on Mendocino core. Mendocino was the first Intel x86 core that integrated level 2 cache with the core (Pentium Pro had level 2 cache on a separate die, and Pentium II processors used external cache chips). The core had only 128 KB of level 2 cache, but smaller cache size was partially compensated by faster cache speed - it was running twice as fast as the Pentium II level 2 cache. The Mendocino core didn't require external cache chips, therefore it could fit on smaller and cheaper Plastic Pin Grid Array (PPGA) package. To work with the Celeron PPGA package Intel designed new 370-pin socket - socket 370, or PGA370.
