What are Intel Core Products Some terminology : Some terminology Core
Thread What is Multi Core : What is Multi Core A multi-core processor (or chip-level multiprocessor, CMP) combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (IC), called a die, or more dies packaged together. A dual-core processor contains two cores, and a quad-core processor contains four cores. P6 microarchitecture : P6 microarchitecture The P6 microarchitecture is the sixth generation Intel x86 microprocessor architecture, released in 1995 and is sometimes referenced as i686. It was succeeded by the NetBurst microarchitecture in 2000, but eventually revived in the Pentium M line of microprocessors. P6 based chips : P6 based chips Celeron (Covington/Mendocino/Coppermine/Tualatin variants)
Pentium II Overdrive (a Pentium II chip in the 387 pin Socket 8)
Pentium II Xeon
Pentium III Xeon NetBurst Microarchitecture : NetBurst Microarchitecture The Intel NetBurst Microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the x86 family of CPUs made by Intel.
This was the first of the Pentium 4 CPUs, and all subsequent Pentium 4 and Pentium D variants have also been based on NetBurst.
In mid 2001, Intel released the Foster core, which was also based on NetBurst, thus switching the Xeon CPUs to the new architecture as well. Technology Features : Technology Features Hyper Pipelined Technology

They run very hot, thus resulting inability to effectively increase clock speed
…..was the primary reason Intel abandoned the NetBurst architecture. Intel Core 32-bit : Intel Core 32-bit The Core brand refers to Intel's 32-bit mobile dual-core x86 CPUs that derived from the Pentium M branded processors. The processor family used a more advanced version of the Intel P6 microarchitecture. It emerged in parallel with the NetBurst (Intel P68) microarchitecture of the Pentium 4 brand. And was a precursor of the 64-bit Core microarchitecture of Core 2 branded CPUs. Slide 12: The Core brand was launched on January 5, 2006 by the release of the 32-bit Yonah CPU - Intel's first dual-core mobile (low-power) processor. Its dual-core layout closely resembled two interconnected Pentium M branded CPUs packaged as a single die silicon chip (IC).
Hence, the 32-bit microarchitecture of Core branded CPUs had more in common with Pentium M branded CPUs than with the subsequent 64-bit Core microarchitecture of Core 2 branded CPUs. Intel Core (Yonah) : Intel Core (Yonah) The Yonah CPU was launched in January 2006 under the Core brand. Single and dual-core versions were sold under the Core Solo and Core Duo brands respectively (the Solo processor being a Duo, but with one disabled core). These processors provided partial solutions to some of the foregoing Pentium M's shortcomings, by adding to its P6 microarchitecture:
Dual-core technology with shared L2 cache (restructuring processor organization) Yonah variant : Yonah variant Celeron M 400 series
Pentium Dual-Core T2060/T2080/T2130
Xeon LV/ULV (Sossaman) Intel Core 64-bit microarchitecture : Intel Core 64-bit microarchitecture The Intel Core microarchitecture (previously known as the Intel Next-Generation Micro-Architecture is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based around an updated version of the Yonah core and could be considered the latest iteration of the Intel P6 microarchitecture, which traces its history back to the 1995 Pentium Pro. Slide 17: The Intel Core Microarchitecture was designed by the Intel Israel (IDC) team that previously designed the Pentium M mobile processor.
Thermal Design Power (TDP)
Enhanced SpeedStep Technology Intel Core 2 Processors : Intel Core 2 Processors The Core 2 brand refers to a range of Intel's consumer 64-bit single- and dual-core and 2x2 MCM (Multi-Chip Module) quad-core CPUs with the x86-64 instruction set, based on the Intel Core microarchitecture, derived from the 32-bit dual-core Yonah laptop processor. Slide 19: The Core 2 brand was introduced on July 27, 2006, comprising the Solo (single-core), Duo (dual-core), Quad (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. Intel Core 2 Processors : Intel Core 2 Processors Intel Core 2 Duo
