Intel Corporation's trade name for its family ofPentium II microprocessors meant for use in low-endcomputers.The Celeron is constructed on the 0.25 micron Deschutes base.Clock rates of 266, 300 and 333 MHz are supported. It isbuilt on the same daughterboard as the Pentium II withoutthe black plastic case and heat sink. Four Celeron modelsare in production as of October 1998. The 266 and 300 MHzmodels are essentially Pentium II CPUs without the Level 2cache RAM. The 300A and 333 MHz Celerons include 128k ofLevel 2 cache.A special mounting bracket on the motherboard is used tosecure the Celeron in place in its standard 242-pin Slot 1socket. Intel calls the caseless design SEPP (Single EdgeProcessor Package) to differentiate it from the Pentium II SEC(Single Edge Cartridge). Some believe that the real purposefor the different mounting configurations is to prevent usersfrom placing lower cost processors onto Pentium IImotherboards.A Celeron is about one third the cost of a similar speedPentium II. Hardware hackers claim that the Celeron 300without Level 2 cache could be overclocked to perform aswell as a Pentium II at a fraction of the price.
