The Core microarchitecture returned to lower clock rates and improved the usage of both available clock cycles and power when compared with the preceding NetBurst microarchitectue of the Pentium 4/D-branded CPUs.[2] The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs, while increasing their processing capacity. Intel's CPUs have varied wildly in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables.

Core-based microprocessors do not have Hyper-threading Technology found in Pentium 4 processors. This is because the core microarchitecture is a descendant of the P6 microarchitecture used by Pentium III, Celeron and Xeon processors based on it. Core 2 also lacks an L3 cache found in the Galllatin core of Pentium 4 Extreme Edition, Although an L3 cache is present in high-end versions of Core-based Xeons and Hyper-threading is present on select Atom processors. Both an L3 cache and Hyper-threading is present in current Nehalem and future Westmere processors.

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 micro architecture. It emerged in parallel with the NetBurst (Intel P68) micro architecture of the Pentium 4 brand, and was a precursor of the 64-bit Core micro architecture 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 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 (piece) silicon chip (IC). Hence, the 32-bit micro architecture of Core branded CPUs - contrary to its name - had more in common with Pentium M branded CPUs than with the subsequent 64-bit Core micro architecture of Core 2 branded CPUs. Despite a major rebranding effort by Intelstarting January 2006, some computers with the Yonah core continued to be marked as Pentium M.

The Core series is also known for being the first Intel processor to be used as the main CPU for an Apple Macintosh computer. The Core Solo appeared in Apple's Mac Mini line. Core Duo signified the beginning of Apple's shift to Intel processors across their entire line.

In 2007, Intel began branding the Yonah core CPUs intended for mainstream mobile computers as Pentium Dual-Core. These are not to be confused with the desktop 64-bit Core micro architecture CPUs also branded as Pentium Dual-Core.

Hard Disk Drive

A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non volitile storage device that stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media

DDR SDRAM

DDR SDRAM double data rate synchronous dynamic random access memory) is a class of memory integrated circuits used in computers. It achieves nearly twice the bandwidth of the preceding SDR ("single data rate") SDRAMby double pumping (transferring data on the rising and falling edges of the clock signal) without increasing the clock frequency.

With data being transferred 64 bits at a time, DDR SDRAM gives a transfer rate of (memory bus clock rate) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s

"Beginning in 1996 and concluding in June 2000, JEDEC developed the DDR (Double Data Rate) SDRAM specification (JESD79)."

Jedec has set standards for data rates of DDR SDRAM, divided into two parts. The first specification is for memory chips, and the second is for memory modules. As DDR SDRAM is superseded by the newer DDR2 SDRAM, the older DDR version is sometimes referred to as DDR1 SDRAM

Motherboard P3

A motherboard is the central printed circuit board (PCB) in some complex electronic systems, such as modernpersonal compute The motherboard is sometimes alternatively known as the mainboard, system board, or, onApple computers, thelogic board] It is also sometimes casually shortened to mobo.
