HOW TO CHOOSE BEST LAPTOP PROCESSOR

Processors for laptops are very different compared to their counterparts in traditional systems.
The first reason is due to the decrease of energy with which they must work when the laptop is not connected to the power plug. The laptop uses less energy and longer is the autonomy of our battery. To do this, the processor manufacturers years implemented a large number of tricks like scaling CPU (processor lowers its clock and thus its performance to save power).
Here there are four distinct categories to classify their laptops and processors.

Low-cost systems

The low-cost systems have been developed with the intention of making a portable computer for the most common operations svolegere office automation at a low cost

All processors in this category are able to perform all normal operations like browsing the Internet, check email, word processing, making presentations and so on. They are also able to play DVDs.

The only thing these systems are not able to do well is play and high-level graphics applications. Below are some processor that belongs to this category:

    * Mobile AMD Sempron 3000 + and higher
    * Mobile AMD Athlon 64 3200 + and higher
    * AMD Turion 64 ML-32 or MT-32 and below
    * AMD Turion 64 X2 TL-50 or TL-52
    * Intel Celeron M 350 and above
    * Intel Core 2 Duo T5500 and Lower
    * Intel Core Duo T2050 to T2400
    * Intel Core Solo
    * Intel Pentium M 760 and lower

Ultralights

Ultralights are systems that are designed to be lighter and more compact and powerful enough to perform the most common office automation tasks (email, word processing and presentations). These laptops suitable for people who travel a lot and want a system that is not cumbersome sacrificing power for portability. Here on these processors elec systemicity

    * Intel Pentium M LV and ULV Series
    * Intel Core Solo U1300 and U1400
    * Intel Core Duo L2500 L2300E up to
    * Intel Core Duo U2400 and U2500

Light

A laptop is a lightweight notebook that runs all the applications - at least to a certain level - without major problems. These systems offer a variety in terms of price and performance. Perform the operations better than their counterparts in the two previous categories and are smaller and more portable than the so-called desktop replacement. Here are some processors that can be found in these categorieç

    * Mobile AMD Athlon 64 3200 + and higher
    * AMD Turion 64 3200 + and higher
    * AMD Turion 64 X2 ML-32 or MT-32 and higher
    * Intel Core 2 Duo T5500 or T7200 and above
    * Intel Core Duo T2300 and above
    * Intel Pentium M 760 and above

Desktop Replacement (Sitem to replace a desktop)

Desktop replacement systems are designed to be equivalent to a desktop system with regard to capacity and computing power but in a "box" easily transportable. Obviously they are larger and bulkier laptops belonging to the previous categories.

Generally you can also use for 3D games, having (almost) the same performance of a desktop system consist although much more and still not reach the same level of the best desktop graphics. Below are some processors in this category:

    * AMD Turion 64 MT-34 and higher
    * AMD Turion 64 X2 TL-56 and higher
    * Intel Core 2 Duo T5600 or T7200 and above
    * Intel Core Duo T2600 and above

HOW TO CHOOSE A GOOD CPU PROCESSOR

The manufacture of CPU is one of the most competitive in the world. At the end of the performance of your desktop or laptop depend on the CPU. In relation to user demand, we can say that the GOOD CPU PROCESSOR that are used today belong to families from Intel and AMD. The cache memory is definitely the most important factor in the equation balancing (trade-off) between price and performance. Considering the L2 cache on some of the chips on the market you can see how Athlon, P4 and PIII, which have 256K L2 cache or more have the highest performance. Looking at one of the cheaper chips can immediately see that the Celeron has 128K of L2 cache, and Duron processors with only 64K.

The Celeron currently has performance close to the PIII with half the cache disabled.
This figure shows that the builders put enough CPU cache on the chip has a high cost. Another parameter that differentiates the CPU on which to focus is the "bus speed" (bus speed). Based on this parameter Athlon and P4 have a bus between cache and CPU speed is respectively 200 and 400MhHz. This parameter allows your system to have better performance when there are applications that intensively use the cache. New CPUs have quadrupled this parameter, for example, P4 has 800MHz.
The number that you see the first unit of measure "Micron" in the comparison tables indicates a CPU basically has size of transistors. The higher this number is small, more transistors can be inserted into the container (d) of the CPU. The smaller the transistors become smaller containers of more CPUs. The smaller containers of less CPU power is required.

 
The CPU instruction set is all the code that the CPU is able to interpret process data. The higher the CPU instruction set, the greater its efficiency. However, at this point Intel and AMD are not following the same path. Intel puts first his attention to improving the set of basic instructions which adds support for MMX multimedia.
The differences between the CPUs are becoming very small between the various manufacturers, each observes the strengths of rival technologies and try to emulate them. It 'hard to choose which is best among all. The manufacture of CPU is one of the most competitive in the world. At the end of the performance of your desktop or laptop depend on the CPU.

Cpu Processor Speed Determination


Now I Will discuss Cpu Processor Speed. If You can think of the computer's CPU, also known as the processor, as the computer's brain. The faster processors generally offer better presentations than slower processors and their use is particularly useful for running multimedia programs, such as games or audio or video editing programs.

The speed of a computer processor describes the maximum number of calculations per second the processor can execute and is expressed in megahertz (MHz) or gigahertz (GHz). In general, the higher the number, the faster and more powerful processor.

    1. To open System, click the Start button, click Control Panel, System and Maintenance, and then click System.
    2. Under System shall include the processor type and speed, and the number of processors installed, if your computer uses multiple processors.

Complete Guide To Buy Cpu Processor


Guide to buy cpu processor: How do you choose a CPU? What technical characteristics must be taken into consideration for judging the performance

there are something to consider if you want to  buy a cpu processor

Number of Core

The number of Core is the very first thing to look at, when people read the technical characteristics of a processor.
It 'a great indicator of what will be the performance of your computer.

In theory, most of which are the core in the processor is in possession, the performance will be more interesting and multi-threading will not be a problem.

Note: Multithreading improves performance only when these programs were developed by dividing the workload on multiple threads that can run in parallel. Multiprocessor systems are equipped with multiple independent computing units, a multi-threaded but has a single unit of computing that seeks to best use multiple threads running in the same unit of calculation. The techniques are complementary, sometimes multiprocessor systems also implement multithreading to improve overall system performance.

Currently (at which time writing) you can find on the market for processors that implement two or three (only AMD), four and six Core.

We feel strongly advise processors that implement 3 or 4 cores.
They represent, in fact, very balanced solutions that offer excellent support multithreading + frequency of work (often) higher than the 6-core processors.

Core 2 processors are good only as a fallback in case of hardship or compatibility of hardware to comply.

We recommend that you opt for a 6 Core processor if and only if you use programs that can benefit from this type of architecture.

buy cpu processor Cache Memory

The term cache refers to that portion of the temporary memory used because they guard that information that need to be retrieved quickly on the request of the processor.

One thing common to all processors (currently) is the simultaneous presence of two caches.
A first level (known as L1) and a second level (L2).
Most often the producer decides to implement the same cache, the first and second level, on all processors that belong to the same generation architecture.

Processors, capable of the most important performance than the average, also have a third level of memory that is shared between the cores: L3.


buy cpu processor Frequency


Once it was the information that the seller is required to understand the performance he was capable of a processor.
Today, this factor has lost some 'of its importance to preserve the number of cores.
However, it remains a parameter to be evaluated carefully because it indicates the processor speed, but can be a basis of comparison only if all other characteristics (considered one of the CPU) are comparable.

If, for example, we want to compare two quad core processors from the same manufacturer, which belong to the same family and have the same cache, then the one with the largest number in attendance, will also be equipped with the greater speed of execution and therefore , will be the most powerful.

But this argument collapses when we wanted to compare a dual core CPU with one that has fewer than 6 cores.

In this case it is not at all sure that the CPU with 4 cores is more of a performance with 6 core that operates at a lower frequency.

A straight that we feel to be able to give (generalizing) is that a processor that takes 3 or 4 cores and exercising at a frequency of 2.5 GHz (or more) is powerful enough to handle games and applications of a certain level. That is to say, they can easily keep up with the needs of average Italian family.

buy cpu processor Core Turbo and Turbo Boost

As we noted in the section on "Frequency", the processors have reached a degree of evolution that it forces us to consider many things before you can buy one.
Among those also listed two technologies that we have mentioned several times in the course of our reviews.

We refer to the Turbo Core AMD and Intel Turbo Boost.

Both operations are going to change the operating frequency.
The concept on which they are based is very simple.

Because a computer maximizes its processor only in specific activities (image editing, video editing, games, etc.), all the time remaining the processor is operating under what are its real possibilities.

What was found of the engineers?
They made sure that the number of active cores were mild and decreased during the operation frequency is increased because the action can use the right power.
This is a momentary overclocking tends to enhance performance of single core in spite of their massive use.

This translates into significant benefits for the PC. First of all electrical and decrease fuel consumption and, in the case of portable, battery life increases.

We want to bring an example car. Imagine you bought a car from the high displacement. Let's pretend it's a 2000.
We all know that a machine of such features will have significant consumption.
Now imagine you can push a button (in the PC is automatic), which reduces the capacity of the machine at certain times, such as stopping at traffic lights, a traffic jam on the freeway, etc ...

buy a cpu processor Hyper-Threading

Every time we reviewed a notebook with Core i7 i5 or, we always brought up (in addition to the Turbo Boost technology) also Hyper-Threading.
We're talking about, then, only Intel processors.

This technical adjustment to allow processors to take advantage of the double of their physical cores.
Consequently, the executable threads are also doubled.

The performance benefit of approximately 20% (again with the same characteristics! Never compare two different processors in the architecture and functions).

Black Edition & Extreme Edition

The first term is typical of AMD, the second of Intel.
This term tends to diversify a certain class of processors that allow the user to change the multiplier of the internal operating frequency (in other models of the CPU multiplier is fixed irreversibly).

Translated into more direct terms, gamers can enjoy high performance and overclocking the processor-are purchased.

buy cpu processor Storage Controller

The memory controller is a direct support to the RAM, in particular to DDR3.
Usually this channel is double. Only the line Core i7 Extreme processors incorporate a three-channel controller.
It goes without saying that this parameter is important when you need to buy RAM banks.

buy cpu processor Production Technology

Nearly every year the production technology varies and is an indicator of the generation of the processor belongs.
We are referring to the architecture with which a CPU is produced.

At the time of writing, the processors are manufactured with technology from 45 nanometers or 32 nanometers.
The latter is preferred because it allows a lower power consumption and, in any case, the same consumer, the models possess higher operating frequencies.

buy cpu processor Parameter TDP

This parameter indicates the maximum power provided by the manufacturer.
This number is reached only when the CPU run at full speed.
It 'important to consider this value when you need to choose an adequate heat sink.
But in this regard is very useful to buy processors in their retail package that contains both the CPU heat sink is adequate for standard use of the product.

Socket

If you have already have a motherboard that would become essential to check that the socket will then be coupled with the motherboard.
If you buy a computer in full, it is important to check the socket.
It becomes, when you buy the components one at a time and then assemble them.

Multimedia Instructions

What is AMD or Intel processor integrates a set of instructions that accelerate multimedia functions (think of the compressed video content).
The term used to identify these statements is SSE (Streaming SIMD Extensions). The version is indicated by a progressive number: eg, 4.1 - 4.2 etc. ..

buy cpu processor Consumption

When you buy a desktop computer, probably the first thought goes to consumption.
The story is different when you shoot at stake notebook computers.
The consumer is in fact an important discriminating on battery life.

Consumption also depends on the technical characteristics of the CPU.
The higher the frequency, the more cores, more coarse the production process and the higher the consumption.

BEST INTEL PROCESSOR for notebook


for a notebook that 'the best intel processor ? Core i5 430M (2.53GHz) or c 'also Melgar? and several series Intel dual core with abbreviations: P, T or S? and numbers (type S7000 or S8000 ...)??? etc.

Here you trigger a good discussion on what are the characteristics for the best intel processor for laptop, because for some it is the best one that consumes less, for others the highest-performing and so on.

Low-cost systems

The low-cost systems have been builded to make a portable computer for the most common operations svolegere office automation at a low cost

All best intel processors for these cases to perform all normal operations like browsing the Internet, check email, word processing, making presentations and so on. They are also able to play DVDs.

    * Intel Core 2 Duo T5500 and Lower
    * Intel Core Duo T2050 to T2400
    * Intel Core Solo
    * Intel Pentium M 760 and lower

Ultralights

Ultralights are systems that are designed to be lighter and more compact and powerful enough to perform the most common office automation tasks (email, word processing and presentations). That is not cumbersome sacrificing power for portability. Here on these processors elec systemicity

    * Intel Pentium M LV and ULV Series
    
* Intel Core Solo U1300 and U1400
    * Intel Core Duo L2500 L2300E up to
    * Intel Core Duo U2400 and U2500

    * Intel Pentium M 760 and above

Desktop Replacement

Desktop replacement systems are designed to be equivalent to a desktop system with regard to capacity and computing power but in a "box" easily transportable. Obviously they are larger and bulkier laptops belonging to the previous categories.

Generally you can also use for 3D games, having (almost) the same performance of a desktop system consist although much more and still not reach the same level of the best desktop graphics. Below are some best intel processor in this category:

    * Intel Core Duo T2600 and above


and the other best intel processor are i5 and i7

Intel has officially unveiled the Core i7 quad-core processor for laptops. The core, codenamed Clarksfield (45nm), is the variant of the core Lynnfield notebook, desktop solution that we have seen in this review.

The three models for the best intel processor, starting from the flagship Core i7 920XM, characterized by 2 GHz frequency, which becomes 3.2 GHz Turbo mode. The L3 cache is 8 MB, while the maximum TDP is set at 55 watts. the trio is the Core i7 820QM, who works at 1.73 GHz - 3.06 GHz Turbo mode. Even in this case have been integrated 8 MB of L3 cache, while the TDP is lower, at 45 watts. Finally we have the Core i7 720QM, with a frequency of 1.6 GHz to 2.8 GHz that rise in Turbo mode. In the case of this model is 6 MB L3 cache, while the TDP is still 45 watts.

Turbo mode adjusts the CPU multiplier based on the workload, running a dynamic overclocking. The best intel processor can detect how many cores are in use, and then automatically select a default multiplier. Another example for Lynnfield, Mobile Core i7 CPUs support dual-channel DDR3-1333 and have 16 lanes for PCIe 2.0 connectivity built into the CPU die. The chipset that communicates with the CPU is called, even without too much imagination, PM55 Express.
Unlike Intel Core i5 desktop, mobile have i7 Hyper-Threading enabled.

BEST CPU PROCESSOR THE WORLD FAMOUS


The best cpu processor between Intel and AMD is the fulcrum of the battle for the migiore processor on the world stage. A dualism that can be compared to that between Canon and Nikon in photography, including Apple's iPhone OS and Android in the mobile operating systems, or between Apple and Microsoft in general science. What is currently the best choice for a processor moves between these two choices? We try to offer a comparison for various price ranges from a low to a high, rising from an intermediate. And you, what choice you made between the two contenders? Let us know in the comments.

If the processor and therefore economic entrylevel mean a product about a hundred dollars  then we can rely on AMD Athlon X3 II 455 (80 euros), a model that contains three core very fast and allows you to overclock the price with a certain freedom. If you want to opt for an Intel model Intel Core then here is available i3 540 slightly more powerful and more expensive. Returning to the technical details of the chosen criteria, Athlon II X3 455 aka Frog, with a manufacturing process to 45 nm at a frequency of 3.3 GHz, Socket AM2 + / AM3, L1 Cache 3 x 128 KB L2 Cache: 3 x 512 KB, HyperTransport 4000 MT / s and consumes 95 W.

Best cpu processor | mid-range

In the area of ​​the middle range that moves around 200 euros, Intel Core i5 2500K Sandy Bridge has a 32-nanometer production process, 3.3 GHz with the turbo rising to 3.7GHz, LGA 1155, 4 x 256KB L2 cache, 6MB L3 Cache and consumes 95W. The power of this processor is guaranteed and promoted by the multiplier unlocked, even if you do not use Hyper-Threading. Work at 3.3GHz but can use the Turbo Boost to go up to 3.7GHz. In all this, however, energy consumption is significantly lower than in the past.

Best cpu processor of high range

In the medium-high range around 300 euros, we find the new Intel Core i7 2600K quadricore Sandy Bridge with 32-nanometer production process, frequency of 3.4GHz, which can go up to 3.8GHz, LGA 1155, L2 Cache, 4 x 256KB, L3 Cache 8MB and a power consumption of 95W. And if you really wanted to exaggerate? Then always staying in the catalog of Intel, here is the Core i7 Extreme Edition, which costs approximately 990X 1000 euro and that has long been known by the code name Gulftown. Work to 32 nanometers, has six cores, a frequency of 3.33GHz, LGA 1366, x 256KB L2 Cache 6, 12MB L3 cache, QPI 6.4 GT / s and a consumption of 130W. He is currently the fastest CPU available and can accommodate no overclocking with the multiplier blocks.

About epic battles, here is the comparison between Nikon and Canon and between Nvidia and the other video card manufacturers.

Cpu Processor explanation

The central processing unit (cpu processor), better known as CPU, is also called the processor, or microprocessor , is one of two main components of von Neumann stored-program, on which the model is based most modern computers.

The task of the CPU is to execute the instructions of a program (which must be present in memory). During program execution, the CPU reads or writes data in memory depends on the result of data on which it operates and the internal state where the CPU is the same, you can keep track of past transactions.


According to the organization of memory, there are two CPU PROCESSOR families:

     - With classical von Neumann architecture, where data and instructions reside in the same memory (thus it is possible to have self modifying code). This architecture is the most common because it is very simple and flexible.
     - With Harvard architecture, where data and instructions reside in two separate memories. This architecture can provide better performance since the two memories can work in parallel by reducing structural hazards, but it is obviously much more complex to manage. It is typically used in DSP.

Both architectures are based architectures, however, general registers.

Heat Sink Definition in a cpu


Heat Sink Definition In a cpu is a device that allows the lowering of the temperature of components that give off heat like the transistor or processors, preventing overheating of the same cause it to malfunction, shutdown or failure.

The materials used are copper and aluminum, the first is used in cases where it should be the maximum efficiency in heat transfer, accepting the higher cost and higher specific weight, aluminum is chosen for less demanding operating conditions. Heat Sink Definition for All CPUs have them because of the heat generated. It is usually shaped toroidal blades configured to increase the efficiency in heat dissipation, is coupled to a fan powered by a small electric motor (connected directly to the motherboard) that provides a flow of ventilation air. There are many other forms, conformed according to the components that have to pluged, in some cases, mainly bulky equipment evolving much heat, are part of the carrier frame. When you need extreme performance and small footprint, we adopt the solution called "ventilation", as in the case of CPU or electronic instrumentation.

Particular attention should be paid to the coupling between the mechanical device that generates heat and the heat sink, for maximum efficiency, is interposed between two surfaces in contact, thermal paste, which functions as a completely eliminate the veil of air inevitably present, being the itself a poor thermal conductor, would limit the efficiency.

BIT Definition 16-bit - 256-bit

Bit Definition for the smallest unit of data in a computer tells you whether a transistor (chip component) leads or less. As a BIT binary digit can have 2 values​​: 0 or 1.

On the computer, the bits are used in groups called Word, which have different length depending on system architecture. The computers were first-generation architecture with 4 or 8-bit: they could then manipulate 4 or 8 bits at a time.
Technological advances have led to the construction of systems capable of using 16, 32 and 64 bits.

Bit Definition In 2011, the year in which it was updated this entry in the glossary, you start talking about computers with 128-bit architecture, while the 256-bit size is still a fiction, but you can be sure that in a few years, if not even a few months, these technologies will become obsolete, replaced by others at the moment beyond any imagination.

Rom Definition : Read Only Memory


Rom Definition : contains the basic instructions for operating the computer. The ROM chip instructions and retain data even when powered down.

The ROM (Read Only Memory) is a type of memory that only allows the read data, because its content is permanently set during construction of memory itself.

The circuits of the ROM memory contain the basic instructions for operating the computer.The
non-volatile ROM that holds instructions and data even if power is lost.

HARD DRIVE DEFINITION, disk drive definition


The purposes of this hard drive definition is a hard drive in a  computer , often called "disk drive" "hard drive", or "hard disk drive" that stores and provides relatively fast access to large amounts of data on a surface or a set of charged surfaces electromagnetically. Today's computers are usually equipped with a hard drive that contains several billion bytes (gigabytes) of storage.

Hard Drive, is a mass storage device that contains one or more non-flexible plates made ​​of ceramic or aluminum, coated with magnetic material and subjected to a constant rotation. May contain large amounts of data

Ram Definition | Random Access Memory

Ram Definition The main memory of the computer work. In RAM are sent running programs and data are processed. RAM when the computer shuts down, it loses all of its contents. Part of the RAM can be included on the motherboard, although it is usually in the form of interchangeable modules SIMMs or DIMMs, which allow the expansion. There are different types of RAM DEFINITIO in the SIMM (EDO and FPM) and DIMM (SDRAM, DDR and SLDRAM).

Ram Definition is the place in which they are contained in the computer operating system, applications and data in use so they can be quickly retrieved by the processor. RAM is much faster to read and write than other storage systems such as a computer hard drive, floppy drive and CD-ROM. However, the data in RAM is retained only as long as the computer is turned on. When the computer turns off the RAM loses its data. When the computer is on, the operating system and other files must be reloaded into RAM, usually from your hard drive.

Ram Definition can be compared to short-term memory and hard drive in people with long-term memory. The short-term memory focuses on the work at hand, but few can maintain information at a time. If the short-term memory fills up, your brain sometimes is able to store information in long-term memory. Even a computer works this way. If RAM fills up, the processor must constantly access the hard drive to replace the old data in RAM with new, slowing down the operation of your computer. Unlike the hard disk that can become completely full of data and not accepting others, the RAM runs out of memory. Remains operational, but much more slowly than is desirable.
This is a short articles from ram definition, hope you enjoy.
