Intel Core 2 microprocessors
The Core 2 brand refers to Intel's x86/x86-64 microprocessors (with the eighth-generation microarchitecture, named Core architecture) targeted at the consumer and business markets (except the servers) above Pentium Dual-Core. The Core 2 Duo branch covered dual-core CPUs for both desktop and notebook computers, Core 2 Quad - quad-core CPUs for both desktop and notebook computers, and Core 2 Extreme - dual-core and quad-core CPUs for both desktop and notebook computers.
Core successor
The successor to Core is the mobile version of the Intel Core 2 line of processors using cores based upon the intel core monoarchitecture, released on july 27 2k7. The release of the mobile version of Intel Core 2 marks the reunification of Intel's desktop and mobile product lines as Core 2 processors were released for desktops and notebooks, unlike the first Intel Core CPUs that were targeted only for notebooks (although some small form factor and all-in-one desktops, like the iMAC, also used Core processors).
Unlike the Intel Core, Intel Core 2 is a 64-bit processor, supporting Intel 64. Another difference between the original Core Duo and the new Core 2 Duo is an increase in the amount of Level 2 cache. The new Core 2 Duo has doubled the amount of on-board cache to 4 MB. Both chips have a 65 nm process technology architecture and support a 667-1333 MHz front-side-bus (FSB).

Intel Core 2
The Core 2 brand refers to a range of consumer single- and dual-core and 2x2 MCM (Multi-Chip Module) quad-core with the instruction set, based on the Intel core, derived from the 32 bit laptop processor. The 2x2 dual-die quad-cor CPU had two separate dual-core dies (CPUs)—next to each other—in one quad-core package. The Core 2 relegated the pentium to a mid end market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, D, and M brands.
The Core microarchitecture returned to lower clock rate and improved processors' usage of both available clock cycles and power compared with preceding the pentium 4. microarchitecture provides more efficient decoding stages, execution units, and buses, reducing the Core 2-branded , while increasing their processing capacity. Intel's CPUs have varied very wildly in power consumption according to clock rate, architecture and semiconductor process, shown in the tables.
The Core 2 brand was introduced on July 27, 2006,comprising the Solo (single-core), Duo (dual core and quad core, , and in 2007, the Extreme (dual- or quad-core CPUs for enthusiasts) version. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches.
The brand became immediately successful. The processors were introduced into Apple's popular MacBook series of notebooks, at the time Apple CEO justified the entire switch to Intel from IBM's processors by the Core 2 series' ability to provide high performance at low power consumption. The series of processors reasserted Intel's role in the processor market after a period in which began significantly encroaching on Intel's market share. The processor series became so successful that Anand Lal Shimpi coined the phrase "Conroe" as a verb to describe the releasing of a product that eclipses the competition in a previously hotly contested market

Intel Core
The Core brand refers to intel's 32-bit mobile dual core that derived from the processors. The processor family used a more advanced version of the Intel p6. It emerged in parallel with the (Intel P68) microarchitecture of the pentium4 brand, and was a precursor of the 64k bit of Core 2 branded CPUs. The Core brand comprised two branches: the Duo (dual-core) and Solo (Duo with one disabled core, which replaced the Pentium M brand of single-core mobile processor).
The Core brand was launched on jan 5 2k6 by the release - Intel's first dual core mobile (low-power) processor. Its dual-core layout closely resembled two interconnected CPUs packaged as a single (piece) silicon chip . Hence, the 32-bit microarchitecture of Core branded CPUs - contrary to its name - had more in common with Pentium M branded CPUs than with the subsequent CPUs. Despite a major effort by intel starting January 2006, some computers with the Yonah core continued to be marked as Pentium M.
The Core Duo is also famous for being the first Intel processor to ever be used in apple computers. Core Duo signified the beginning of Apple's shift to Intel processors across their entire line.
In 2007, intel began branding the Yonah core for mainstream mobile computers as Pentium dual core. These are not to be confused with the desktop CPUs also branded as Pentium Dual-Core.
September 2006 and January 4, 2008 mark a discontinuation of many Core branded CPUs.
