Intel I7 series has many outstanding features. Clock speed is improved significantly within temperature and power limit with the help of turbo boost technology. This technology increases efficiency without any afford any extra effort or power. In I7 series, each processor has explicitly its own dedicated memory.

QPA is designed in away it reduces execution time and latency time. Your email address will not be published. Thesecome in a wide range of performance and power consumption, starting with the relativelyslow ultra-low-power Uxxxx 10 W and low-power Lxxxx 17 W versions, to the moreperformance oriented Pxxxx 25 W and Txxxx 35 W mobile versions and the Exxxx 65W desktop models. Within each line, a higher number usually refers to a better performance, which dependslargely on core and front-side bus clock frequency and amount of second level cache, whichare model-specific.

Core 2 Duo processors typically use the full L2 cache of 2, 3, 4, or 6 MBavailable in the specific stepping of the chip, while versions with the amount of cachereduced during manufacturing are sold for the low-end consumer marketas Celeron or Pentium Dual-Core processors. Like those processors, some low-end Core 2Duo models disable features such as Intel Virtualization Technology.

Details can be found atthe list of Intel Core 2 microprocessors. Core 2 QuadCore 2 Quad processors are multi-chip modules consisting of two dies similar to those usedin Core 2 Duo, forming a quad-core processor. This allows twice the performance of dual-core processors at the same clock frequency in ideal conditions.

The Xeon 32xx and 33xx processors are mostly identical versions of the desktop Core 2Quad processors and can be used interchangeably. Core 2 ExtremeCore 2 Extreme processors are enthusiast versions of Core 2 Duo and Core 2 Quadprocessors, usually with a higher clock frequency and an unlocked clock multiplier, whichmakes them especially attractive for overclocking.

This is similar to earlier Pentium processors labeled as Extreme Edition. Chapter 6.

Nehalem Microarchitecture BasedWith the release of the Nehalem microarchitecture in November , Intel introduced anew naming scheme for its Core processors.

There are three variants, Core i3, Core i5 andCore i7, but the names no longer correspond to specific technical features like the number ofcores. Instead, the brand is now divided from low-level i3 , through mid-range i5 to high-end performance i7 , which correspond to three, four and five stars in Intels Intel ProcessorRating following on from the entry-level Celeron one star and Pentium two stars processors. Core i3The Core i3 was intended to be the new low end of the performance processor linefrom Intel, following the retirement of the Core 2 brand.

The first Core i3 processors werelaunched on January 7, The same processor is also available as Core i5 and Pentium,with slightly different configurations.

The Core ixxM processors are based on Arrandale, the mobile version of the Clarkdaledesktop processor. They are similar to the Core ixx series but running at lower clockspeeds and without Turbo Boost. When asked, Intel confirmed that, although the Intel 5series chipset supports non-ECC memory only with the Core i5 or i3 processors, using thoseprocessors on a motherboard with series chipsets it will support the ECC function ofECC memory.

Core i5The first Core i5 using the Nehalem microarchitecture was introduced on September 8, ,as a mainstream variant of the earlier Core i7, theLynnfield core. The same processors withdifferent sets of features Hyper-Threading and other clock frequencies enabled are soldas Core ixx and Xeon series processors, which should not be confused with high-endCore ixx and Xeon series processors based on Bloomfield.

The Core ixx mobile processors are named Arrandale and based on the 32 nmWestmere shrink of the Nehalem microarchitecture. Arrandale processors have integratedgraphics capability but only two processor cores. They were released in January ,together with Core ixx and Core ixx processors based on the same chip.

The L3 cachein Core ixx processors is reduced to 3 MB, while the Core ixx will use the full cacheand the Core ixx will have no support for Turbo Boost. Clarkdale, the desktop version ofArrandale, is sold as Core ixx, along with related Core i3 and Pentium brands. According to Intel "Core i5 desktop processors and desktop boards typically do not supportECC memory", but information on limited ECC support in the Core i3 section also applies toCore i5 and i7.

Core i7Intel Core i7 as an Intel brand name applies to several families of desktop and laptop 64 bit x processors using the Nehalem Westmere, SandyBridge and Ivy Bridge microarchitectures.

TheCore i7 brand targets the business and high-end consumer markets for both desktop and laptopcomputers, and is distinguished from the Core i3 entry-level consumer , Core i5 mainstreamconsumer , and Xeon server and workstation brands.

Intel introduced the Core i7 name with the Bloomfield Quad-core processor in late In new Core i7 models based on the Lynnfield desktop quad-core processor andthe Clarksfield quad-core mobile were added, and models based on the Arrandale dual-coremobile processor were added in January The first six-core processor in the Core lineupis the Gulftown, which was launched on March 16, In January, Intel released the second generation of Core i7 processors.

Both the first and secondgeneration of Intel Core i7 processors are rated as 5 stars in the Intel processor rating. The 17 In each of the first three microarchitecture generations of the brand, Core i7 has familymembers using two distinct system-level architectures, and therefore two distinct sockets forexample, LGA and LGA with Nehalem.

Intel representatives stated thatthe moniker Core i7 is meant to help consumers decide which processor to download as thenewer Nehalem-based products are released in the future. Chapter 7. The initial set of Sandy Bridge processors includes dual- andquad-core variants, all of which use a single 32 nm die for both the CPU and integrated GPUcores, unlike the earlier microarchitectures.

With the mobile version,the thermal design power can no longer be determined from a one- or two-letter suffix but isencoded into the CPU number. Starting with Sandy Bridge, Intel no longer distinguishes thecode names of the processor based on number of cores, socket or intended usage; they all usethe same code name as the microarchitecture itself.

Ivy Bridge is the codename for Intels22 nm die shrink of the Sandy Bridge microarchitecture based on tri-gate "3D" transistors,introduced in April Core i3Released on January 20, , the Core ixxx line of desktop and mobile processors is adirect replacement of the "Clarkdale" Core ixx and "Arrandale" Core ixxMmodels, based on the new microarchitecture. While they require new sockets and chipsets, theuser-visible features of the Core i3 are largely unchanged, including the lack of supportfor Turbo Boost and AES-NI.

The Ivy Bridge based Core-ixxx line is a minor upgrade to 22 nm process technology andbetter graphics. New dual-core mobile processors and desktopprocessors arrived in February The Core ixxx line of desktop processors are mostly quad-core chips, with the exceptionof the dual-core Core iT, and include integrated graphics, combining the key featuresof the earlier Core ixx and Core ixx lines. The suffix after the four-digit model numberdesignates unlocked multiplier K , low-power S and ultra-low-power T.

The mobile Core ixxxM processors are all dual-core chips like the previous Core ixxMseries and share most the features with that product line. Core i7The Core i7 brand remains the high-end for Intels desktop and mobile processors, featuringthe Sandy Bridge models with the largest amount of L3 cache and the highest clockfrequency. Most of these models are very similar to their smaller Core i5 siblings.

They are the best desktopprocessor family on the planet. You will multitask applications faster and unleash incredible digital media creation.

Andyoull experience maximum performance for everything you do, thanks to the combination ofIntel Turbo Boost technology and Intel Hyper-Threading technology, which maximizesperformance to match your workload. Following figure shows internal representation of corei7 processor. Native quad-core structure. Each channel can work with two unbuffered DIMM modules. There is SMT Simultaneous Multithreading technology It allows each Core i7 core to process two computational threads simultaneously, so the operating system sees the processor as an 8-core one.

Core i7 is manufactured with 45nm process, consists of million transistors. Nehalem is the codename for an Intel processor micro-architecture, successor to the Coremicro-architecture. The first processor released with the Nehalem architecture is the desktopCore i7. Various sources have stated the specifications of processors in the Nehalem family: Two, four, six, or eight cores million transistors for the quad core variant 45 nm manufacturing process Integrated memory controller supporting two or three memory channels of DDR3 SDRAM Simultaneous multithreading SMT by multiple cores which enables two threads per core.

Intel calls this hyper-threading. Native monolithic, i. The following caches: Chapter 9. Eight dedicated, physical threads help operating systems and applicationsdeliver additional performance, so end users can experience better multi-tasking and multi-threaded performance across many types of applications and workloads. It provides a higher-performance, more efficient cache subsystem.

Optimizedfor industry leading multi-threaded games. Intel Hyper-Threading TechnologyThe processor supports Intel Hyper-Threading Technology which allows an execution core tofunction as two logical processors.

While some execution resources such as caches, executionunits, and buses are shared, each logical processor has its own architectural state with its ownset of general-purpose registers and control registers. This feature must be enabled using the BIOS and requires operating system support. Intel bit architectureIntel bit architecture delivers bit computing on server, workstation, desktop and mobileplatforms when combined with supporting software.

Intel 64 architecture improvesperformance by allowing systems to address more than 4 GB of both virtual and physicalmemory. It automatically allows processor cores to run faster than the base 27 The maximum frequency of Intel Turbo Boost Technology isdependent on the number of active cores.

The amount of time theprocessor spends in the Intel Turbo Boost Technology statedepends on the workload and operating environment, providingthe performance you need, when and where you need it. Any of the following can set the upper limit of Intel Turbo Boost Technology on a givenworkload: Number of active cores Estimated current consumption Estimated power consumption Processor temperatureNo special hardware support is necessary for Intel Turbo Boost Technology.

Intel core i7 is a family of three Intel desktop processor, the first processor released using the Intel Nehalem micro architecture and the successor to the Intel Core 2 family. The instruction decoder has three decoder units that can decode one simple instruction per cycle per unit.

The other decoder unit can decode one instruction every cycle, either simple instruction or complex instruction made up of several micro-ops. Up to four micro-ops can be delivered each cycle to the instruction decoder queue IDQ. It is an higher turbo boosting frequency which increases its voltage and frequency without violating the power.

The i7 processor is idle for its power gating, as the power gating aims to cut the leakage current as well, thereby further reducing the power consumption of the idle core. The number of active cores, the estimated current consumption, and the estimated power consumption.

Normally , the Core i7 processor can operate at frequencies between 1. With Turbo Boost enabled, the processor can increase the frequency of cores two further levels to voltage, and thermal envelope. The name continues the use of the Intel Core brand. With more threads available to the operating system, multitasking becomes even easier. PowerPoint Presentation: Get more performance automatically, when you need it the most.

The DTS continuously measures the temperature at each processing core.

Each core can complete up to four full instructions simultaneously PowerPoint Presentation: The number of bits or numeral places a CPU uses to represent numbers is often called "word size", "bit width", "data path width", or "integer precision" when dealing with strictly integer numbers as opposed to floating point.

The performance or speed of a processor depends on e. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and applications, some of which take longer to execute than others.Intel Core i5 ProcessorThis is the mid-size processor of this bunch, recommended for those who demand a littlespeed, but not quite enough where the user will be running resource-intensive applications.

Each channel can work with two unbuffered DIMM modules. A single instruction, multiple data SIMD machine is one in which a singleinstruction stream has the ability to process multiple data streams simultaneously.

In most applications except a few gaming titles, the new processors turned outfaster than Core 2 processors working at the same clock speed. Originally, supercomputersknown as array processors or vector processors provided SIMD processing capabilities.
