Intel's current brand of x86 CPUs. Starting in 2006, Core chips superseded the 13-year run of the Pentium; however, the Core name was assigned to three different architectures summarized below, starting with the most recent. See microarchitecture and Pentium.|
Core i Series (i3, i5, i7)
The i7, the first model of the i series was launched in 2008, and the less-powerful i5 and i3 models were introduced in 2009 and 2010 respectively. The microarchitecture of the Core i series was code named Nehalem, and the second generation of the line was code named Sandy Bridge. For more details, see Core i7, Nehalem, Sandy Bridge, Core i3 and Core i5.
Prior to the i series, the 64-bit Core 2 family, introduced in mid-2006, was a major departure from the previous Core Duo chips. Using the Penryn microarchitecture, Core 2 chips became available in single, dual and quad core models. See Core 2.
In early 2006, and based on the existing Pentium M (mobile) architecture, the dual core, 32-bit Core Duo was the first chip introduced with the Core brand. Used only in laptops, the Core Duo chips were superseded by the Core 2 family. See Core Duo.
