Socket models have a single-channel PC DDR-SDRAM memory controller versus the dual-channel controller in Socket models, so Socket models running at the same clock speed and with the same size L2 cache offer somewhat higher performance.

Of course, Intel also designates their recent processors by model number rather than clock speed, confusing matters even further. Unlike AMD which sometimes uses the same Athlon 64 model number to designate four or more different processors with different clock speeds, L2 cache sizes, and sockets Intel uses a numbering scheme that identifies each model unambiguously. For example, a Socket Northwood-core Pentium 4 processor operating at a core speed of 2. Figure Intel Pentium 4 series processor image courtesy of Intel Corporation Socket Pentium 4 models belong to one of two series.

All series processors use the Prescott-core and have 1 MB of L2 cache. Intel uses the second number of the model number to indicate relative clock speed. If a series model number ends in 1 for example, that model supports both the XDB feature and EM64T bit processing.

In fact, the performance bump is generally so small that we think anyone who buys one of these processors has more dollars than sense. If you're considering buying one of these outrageously expensive processors, do yourself a favor. Either that, or keep the extra money in the bank.

Dual-core processors By early , AMD and Intel had both pushed their processor cores to about the fastest possible speeds, and it had become clear that the only practical way to increase processor performance significantly was to use two processors. Although it's possible to build systems with two physical processors, doing that introduces many complexities, not least a doubling of the already-high power consumption and heat production.

AMD, later followed by Intel, chose to go dual-core. Combining two cores in one processor isn't exactly the same thing as doubling the speed of one processor. For one thing, there is overhead involved in managing the two cores that doesn't exist for a single processor. But in a multitasking environment, where many programs and their threads are competing for processor time, the availability of a second processor core means that one thread can run on one core while a second thread runs on the second core.

Dual-core performance for a single application is essentially unchanged unless the application is designed to support threading, which many processor-intensive applications are. For example, a web browser uses threading to keep the user interface responsive even when it's performing a network operation. Even if you were running only unthreaded applications, though, you'd see some performance benefit from a dual-core processor. This is true because an operating system, such as Windows XP, that supports dual-core processors automatically allocates different processes to each core.

AMD Athlon 64 X2 The AMD Athlon 64 X2, shown in Figure , has several things going for it, including high performance, relatively low power requirements and heat production, and compatibility with most existing Socket motherboards. Fortunately, by late AMD had begun to ship more reasonably priced dual-core models, although availability is limited. Under the gun, Intel took a cruder approach to making a dual-core processor. Rather than build an integrated dual-core processor as AMD had with its Athlon 64 X2 processors, Intel essentially slapped two slower Pentium 4 cores on one substrate and called it the Pentium D dual-core processor.

The series 90 nm Smithfield-core Pentium D, shown in Figure , is a stop-gap kludge for Intel, designed to counter the AMD Athlon 64 X2 until Intel can bring to market its real answer, the dual-core 65 nm Presler-core processor, which is likely to be designated the series Pentium D. The Presler-based dual-core processors will be fully integrated, compatible with existing dual-core Intel-compatible motherboards, and feature reduced power consumption, lower heat output, twice as much L2 cache, and considerably higher performance.

They're a kludge, yes, but they're a reasonably cheap, very effective kludge, assuming that you have a motherboard that supports them. We extensively tested an early sample of the least expensive series Pentium D, the The runs at 2.

Many times, the minimum powered core sets are employed to produce advanced tasks. If there is any emergency or requirement, the rapid four sets of cores will be kicked in.

In precise, the octa-core is perfectly defined with dual-code core and adjust it accordingly to give the effective performance. The processor with double core comprises two cores, 4 cores are available with quad cores, six cores are available in hexacore processors.

Deca-core is available with ten independent systems that are deployed to execute and manage the task that is successful than other processors that are developed until now. Owning a PC, or any device made with a deca-core processor is the best option. It is faster than other processors and very successful in multi-tasking. Deca-core processors are trending with its advanced features. Most of the smartphones are now available with Deca core processors with low-cost and never become outdated.

Surely, most gadgets in the market are updated with new processors to give more useful purposes to people. The mid-range processors are called mainstream processors which is comparatively larger and manages high-performance tasks like video editing, 3D gaming, and other multimedia oriented applications.

It is similar to budget-friendly processors that are implemented to execute the fundamental task in a cost-effective method. Such a CPU can be easily managed to operate office programs, photo editing, web browsing, and other basic tasks. This is a guide to Types of CPU.

They have a low processing ability and can only run specific types of programmes. These processors are found in most mini computers.

In most instances, there exist the Pentium types of processors and the Celeron types of processors. The Pentium types of computer processors are used in both laptops and desktops. They are large in size and are normally preferred for high —demand processing.

The Celeron types of computer processors cheap, efficient and compact. The classification above covers some of the most important features of a computer processor. For instance, the cost of the processor, efficiency the amount of work it can handle. Going for High-End processors will imply using the computer for quite a long time without thinking of up — grading or buying another computer to satisfy the change in needs.

Since the manufacture of the types of computer processors, computer processors have since evolved and thus the process of developing the most powerful processors is still on. For instance, the 64 bit types of computer processors were first manufactured by the AMD in after beating the 1 gigahertz speed in Choosing the best type of computer processors solely relies on the intended functions and the ability to pay for the types of computer processor demanded.
