When Pentium II was introduced, some reforms began, such as moving the location of L2 cache from to the processor. At that time, L2 cache was not integrated into the processor, but was placed on the same PCB as the processor, which is the cartridge packaging method.
In fact, similar attempts have been made when the Pentium Pro processor was introduced earlier (Editor: dual-cavity package). The problem is that the cost of this solution is too high, because two cores need to be loaded in the same package: one is Pentium Pro processor, and the other is 256 KB 512KB or 1MB L2 cache.
However, cartridge packaging mode disappeared after August 1998, and Intel began to choose to use socket mode again. This is mainly because the mechanical design of cartridge packaging mode is quite conservative, and complicated heat dissipation design is required, so Celeron PPGA processor is based on socket mode, not socket mode. The processor uses PPGA package and socket 370. Celeron PPGA is also based on the Pentium II Deschutes core, with 8 frequencies of 300 MHz, 333 MHz, 366 MHz, 400 MHz, 433 MHz, 466 MHz, 500 MHz and 533 MHz.
