Recently Intel introduced their newest line of the Pentium 4 processors with the new Prescott core. In this paper I will discuss how the Pentium 4 processor works and the changes that have been made since its release, but mainly on the modifications in the newest Pentium 4's with the Prescott core. I will also briefly compare the performance levels of some of the different types of Pentium 4's.
The Pentium 4 line of processors encompasses a large range of clock speeds, from 1.7GHz up to 3.6GHz in the Prescott chip. Pentium 4's are all built with the same Netburst microarchitecture, but there are varieties of front side bus speeds, chip layout, and cores available. For example at 2.8GHz, one could choose from four different Pentium 4s: the 2.8GHz (a Northwood core with a 533MHz front-side bus), the 2.8C (Northwood again, but with an 800MHz bus), the 2.8A (Prescott with a 533MHz bus), or the 2.8E (Prescott with 800MHz bus). In all there are four types Pentium 4 versions that Intel has released each having slight improvements then the last.
The first Pentium 4 (Willamette) was introduced in November 2000 to replace its predecessor the Pentium 3. The Pentium 4 was the first to have a totally new chip architecture since the 1995 Pentium Pro. The biggest difference being Intel's introduction of the Netburst microarchitecture, which involved structural changes that affected how processing takes place within the chip. Aspects of the changes include: a 20-stage pipeline, which boosts performance by increasing processor frequency; a rapid-execution engine, which doubles the core frequency and reduces latency by enabling each instruction to be executed in a half (rather than a whole) clock cycle; a 400 MHz system bus, which ena...

...helped immensely in offsetting Prescott's enlarged 31-stage pipeline, but did not entirely make up the gap. On balance, Prescotts are slightly slower than Northwoods. In time it is expected that the Prescott P4s will look relatively stronger as SSE3 instructions are adopted in more software application and, especially, as clock speeds rise. But it seems that the real strength of Prescott seems to lie in its Hyper-Threading performance. In the most of the multitasking tests, the Prescott performed better than the Northwood CPU. The Pentium 4 Extreme Edition was the best performer, but unfortunately it is also very expensive. The P4 Extreme Edition had the best results for content creation and video editing applications. Also as Intel suggested the P4 Extreme Edition performed very well for games, but I do not believe it is significant enough to warrant the extra cost.
Process tuning strategy is to minimize the average power consumption of multi-core processors that use the DVFS and CG techniques, while providing the same maximum performance. By scaling the supply voltage (VDD), maximum operating frequency is increased to enhance the performance of a multi core processor. However, increasing VDD is limited by the power and thermal constraints. These constraints can be determined by capacity of supply voltage regulators and cooling solutions in the computing platforms customized for each computing segment.
The processor chosen for my computer build is the Intel BX80662G4400 Pentium Processor G4400 which also comes with a CPU cooler. The software I will be running on my computer is mainly Google Chrome and Microsoft Office 365 Suite. The CPU requirements for Google Chrome is an Intel Pentium 4 or later with that’s SSE2 (Streaming SIMD Extensions 2) capable, the processor I chose is SSE2 capable and is also SSE4 capable making the processor fully capable of running Google Chrome. Now looking at the Microsoft Office 365 Suite the CPU requirements of this software is that the software has to be 1GHz or faster, a x86-bit or x64-bit processor with a SSE2 instruction set. The processor speed for my processor is 3.3GHz which is way more than 1GHz and is a x64-bit processor with a SSE2 instruction set.
“Which is better, AMD or Intel?” is a question that is constantly debated among people involved with computers. There are many reasons to choose one side over another, as both do have their advantages and disadvantages. Intel and AMD are the most prevalent processor production companies, which in turn creates competition between the two. This question is a by-product of that competition. Only by knowing each company and what their product has to offer, can a person make a decision as to what to buy to suit their needs.
Pros: Low-price, high performance. PC Magazine tests show systems based on the 450-MHz K6-III are nearly as fast as those based on the 500-MHz Pentium III (though shop wisely, as components can play a big role in K6-III system performance).
The computer processor is the brain of the system. Our client requires a heavy punch, multi tasking brain. Due to his low income and student status, he does not have a large budget to put towards his computer. The AMD AthlonXP 1900 was chosen because of it's low cost and it's higher performance rating than that of the higher priced equivalent Pentium 4. The AMD AthlonXP 1900's speed is 1.6GHz. This means 1600Hz, which is a very fast processor. Amazingly, the clock speed of this processor is faster, albeit barely, than the Pentium 4 2.0GHz processor, and is much cheaper as well. This is important, as, for less cash, our student can afford a better processor.
The Intel MCS-51, commonly known as the “8051”, is a single chip microcontroller which was developed by Intel in 1980 for use in embedded systems. This “system on chip” accommodates 128 bytes of RAM, 4Kbytes of ROM, 2 Timers, 1 Serial port, and four ports on a single chip.[1] The rise in popularity and success of the 8051 brought forth different versions of the microcontroller from other manufacturers (Intel permitted so). Its popularity remains to this day for it provides a marketable availability, ease-of-use, power efficiency, and integrated features such as USB and radio frequency. Not only is it important to examine the evolution of the 8051, but also take a look at the languages that go hand-in-hand with it. But first, start with the basics.
The Intel roadmap gives some insight into the development of the
The MMX TM Technology extension to the Intel Architecture is designed to accelerate multimedia and communications software running on Intel Architecture processors (Peleg and Weiser). The technology introduces new data types and instructions that implement a SIMD architecture model and is defined in a way that maintains full compatibility with all existing Intel Architecture processors, operating systems, and applications. MMX technology on average delivers 1.5 to 2 times performance gains for multimedia and communications applications in comparison to running on the same processor but without using MMX technology. This extension is the most significant addition to the Intel Architecture since the Intel I386 and will be implemented on proliferation of the Pentium processor family and also appear on future Intel Architecture processors.
The Von Neumann bottleneck is a limitation on material or data caused by the standard personal computer architecture. Earlier computers were fed programs and data for processing while they were running. Von Neumann created the idea behind the stored program computer, our current standard model. In the Von Neumann architecture, programs and data are detained or held in memory, the processor and memory are separate consequently data moves between the two. In that configuration, latency or dormancy is unavoidable. In recent years, processor speeds have increased considerably. Memory enhancements, in contrast, have mostly been in size or volume. This enhancement gives it the ability to store more data in less space; instead of focusing on transfer rates. As the speeds have increased, the processors now have spent an increasing amount of time idle, waiting for data to be fetched from the memory. All in all, No matter how fast or powerful a...

Processor speeds are measured in megahertz (MHz) and now come in speeds of up to 1000 MHz (1 GHz), which is very fast. This is almost ten times faster than the speed of most home computers, which average from 133 MHz to 166 MHz. Intel and AMD have been in a race to break the 1 GHz speed barrier, and the number of megahertz in the newest processors is not as significant as it was in earlier processors. For example, the difference between a 133 MHz processor and a 166 MHz processor is
Desktop computers were commonly used since the late 90’s. The increasing number of applications on desktop computers allowed us to do all kinds of different activities like games, music, video, document editing and so on. In comparison with laptop computers, desktop computers have more stable performance, greater capacities, and throughout history, they have proven themselves more reliable to handle every job they have been assigned.
Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, making presentations, browsing on the internet, playing games, etc. In fact, many people are still confused about choosing what kind of computer they want to buy. In the world today, there are two types of computers: notebook/laptop and desktop. They both are actually very different in several ways. In this paper, I will compare the size, connectivity, power, and price of notebook and desktop computers. I can make these comparisons because I have both a notebook and a desktop computer in my apartment.
Computers are very complex and have many different uses. This makes for a very complex system of parts that work together to do what the user wants from the computer. The purpose of this paper is to explain a few main components of the computer. The components covered are going to be system units, Motherboards, Central Processing Units, and Memory. Many people are not familiar with these terms and their meaning. These components are commonly mistaken for one and other.
This particular computer also intrigued me because of its processor. The processor is a common one, an Intel Pentium 4. I like that Sony decided to stick with Intel, since they are an American brand. The exact processor they used is the Intel Pentium 4 3.6Ghz 560J with HT Technology. The Hyper threading technology is very helpful and I’m glad they decided to use it because it really makes multi-tasking even with complex software faster and more efficient and significantly cuts down on the lag. The 3.6 Gigahertz processor is very very fast and can handle even the most multifaceted functions. The bus speed is also very impressive coming out with a total of 800 solid Megahertz’s. This is an extremely fast bus speed considering it only has one successor the 1066 Mhz speed.
