The Celeron dual-core is a dual-core processor family, which is on the market in 2008. She is the successor to the Intel Celeron (Core) series and represents an affordable alternative to the Pentium processors. These CPUs are based on the Intel Core microarchitecture processor cores Allendale-512 and Wolfdale-1024. The structure width, depending on the version, is 65nm to 32nm. It is used the Socket 775, and later, at the Celeron G version also the Socket 1155. The Celeron G version is since 2011 on the market and is based on the Sandy Bridge architecture with the cores Sandy Bridge-Duo and Ivy Bridge Duo. The Celeron Dual-Core CPUs support a processor clock of 1.6 GHz up to 2.7 GHz and have an L2 cache with a size of 512 to 2048 KiB KiB. Unlike its predecessor, the Celeron Celeron Dual-Core also supports EIST technology, a power saving function, which can be found in the Intel Core processors also.
