.The Xeon "Dunnington" processor (CPUID Family 6, model 30) is closely related to Wolfdale but comes with six cores and an on-chip L3 cache and is designed for servers with Socket 604, so it is not marketed as Core 2. It is mentioned here for completeness.^ Recently, Intel moved to the 45 nm manufacturing process and a new series of processors hit the market under the codenames " "Wolfdale (C2D)", "Yorkfield" (quad core) and "Yorkfield XE" (quad core extreme).

The Intel Core 2 "Wolfdale" microprocessor

Intel Core 2 is a group of microprocessors created to replace Intel's previous Core brand. The group includes the single-core "Core 2 Solo", dual-core (2 cores) "Core 2 Duo", and quad-core (4 cores) "Core 2 Quad" microprocessors. Microprocessors with the name "Extreme" following the brand name, such as Core 2 Extreme, are higher in cost, and perform better than the others. The Extreme versions also come in dual-core and quad-core versions.

Processor Cores

The processors with names ending in "XE" are the "Extreme" versions.

  • Conroe: The first Core 2 Duo processors were released on the Conroe core on July 27, 2006. These were created to replace the Intel Pentium 4 and Pentium D brands. Core version 2 is called Core 2.
