Complete the sentence: the Celeron launched by Intel was initially a stripped-down version of the Pentium II, without the cache chips and plastic casing. The original Celeron was very slow because it had no L2 cache, relying only on the 32 KB of L1 cache. The L2 cache is an extremely important component in current processors because despite the fact that processor performance has increased almost 10,000 times in the last two decades, RAM memory has evolved little in speed. Removing the L2 cache causes the equipment's performance to drop by 40% or more. Therefore, in addition to losing to the Pentium II, the cacheless Celeron even lost to older processors. The first generation was quickly replaced by the Celeron Mendocino, which had 128 KB of internal L1 cache (full-speed), which solved the performance problem. The Mendocino was produced in versions from 300 to 533 MHz, always using a 66 MHz bus. In addition to having a performance close to that of a Pentium II of the same clock (the Pentium II cache is larger but slower), the 300, 333, and 366 MHz versions allowed overclocks of 50%, reaching 450, 500, and 550 MHz with good stability. It was as simple as investing in a good quality cooler and installing the Celeron Mendocino on a motherboard configured to operate at 100 MHz. The Celeron Mendocino was also the first processor to use socket 370, which would later be used by the Pentium III Coppermine and other processors in the family. Adapters were also produced that allowed socket 370 processors to be used on compatible slot 1 boards. In February 1999, the Pentium III was launched. The initial version (which used the Katmai core) did not bring major changes: it was basically a Pentium II that used the SEPP encapsulation, maintained the use of external cache, and operated at 500 MHz. The novelty was the inclusion of SSE instructions that, like AMD's 3D-Now instructions, were aimed at multimedia and 3D applications. Shortly thereafter, in October 1999, the Pentium III Coppermine was launched, an improved version produced in a 0.18 micron technique, which brought 256 KB of integrated L2 cache (operating at the same frequency as the processor) and abandoned the SEPP format in favor of FC-PGA, designed for use with socket 370 motherboards. The change decreed the death of slot 1, which was not used again by other Intel processors. Despite this, the PC-PGA Pentium III versions that used a 100 MHz bus could still be used on most old slot 1 boards, with the help of an adapter (many boards needed a BIOS update).

O Celeron original era muito lento porque não possuía cache L2 algum, contando apenas com os 32 KB de cache L1.
O cache L2 é um componente extremamente importante nos processadores atuais, pois apesar de o desempenho dos processadores ter aumentado quase 10.000 vezes nas últimas duas décadas, a memória RAM pouco evoluiu em velocidade.
O Celeron Mendocino foi produzido em versões de 300 a 533 MHz, sempre utilizando barramento de 66 MHz.
O Pentium III Coppermine foi uma versão aprimorada do Pentium III, produzida numa técnica de 0.18 micron, que trazia 256 KB de cache L2 integrado (operando na mesma freqüência do processador) e abandonou o formato SEPP em favor do FC-PGA, destinado a uso em conjunto com as placas-mãe soquete 370.
O Pentium III Coppermine foi lançado em versões de até 950 MHz, sendo que a partir do Celeron 800 passou a ser utilizado bus de 100 MHz (que melhorou um pouco o desempenho do processador em relação aos antigos).
