The Celeron is a central processing unit( CPU) developed by Intel, a slimmed-down version of the Pentium II and III with an L2 cache of 256 KB. The clock rate is between 260 MHz and 530 MHz in the first version, between 500 MHz and 1 GHz in an improved version with a new processor core in 1999, and the clock rate is up to 1.8 GHz in the version introduced in 2002. In addition, a version with a clock rate of 2.8 GHz was developed in 2003.
The integration density corresponds to ELSI technology with a structure width of 130 nm. The Front Side Bus( FSB) operates with a clock rate of 533 MHz. The Celeron doesn't have hyperthreading and is an inexpensive alternative to other Intel CPUs.
Celerons are available in a wide variety of designs for desktops and notebooks, with different supply voltages, clock frequencies, Thermal Design Power( TDP), L2 caches, Front Side Bus (FSB) and data transfer rates. Celerons are also available as Ultra Low Voltage (UVL) and Consumer Ultra Low Voltage ( CULV) processors.
