Which processor is best, Pentium 4 or Celeron D?

There is one constant you can always depend on with Intel: Anything outperforms a Celeron. There are many reasons for this, all of which can be traced to the physical differences between the two processors. The most important differences between the two lie in their Front Side Busses (FSB), their cache, their clock speeds, and their internal instruction sets. Pentium 4 processors support up to an 800Mhz FSB while the Celeron supports a maximum of 533Mhz. What is the difference? Well, the FSB is the physical connection between the processor and the system's memory. At 533Mhz, the data transfer rate is theoretically 4.2 gigabytes per second. At 800Mhz, it goes up to 6.4 gigabytes/second. When dealing with applications that process intensive graphics or audio files, this makes a HUGE difference. Now, let's look at clock speeds. The Celeron's maximum clock speed as of right now is 3.33Ghz, and the Pentium 4 is 3.8 Ghz. In today's world, a 500Mhz difference won't impact performance as much as, say, 3 years ago. But still, 500 more Mhz won't at all hurt you! Now, let's look at perhaps the most important thing of all--cache. Cache is memory that is stored on the processor itself. It is used ALL THE TIME. The processor stores files/instructions in it's cache for instant access (the data transfer rate of the cache in the Pentium 4 is over 30 gigabytes/second!) and uses internal logic to decide which things to store in there. Obviously, the more cache the processor has, the more things it can store. The Celeron has 256 KB of cache which, in today's world, is horribly low. Most Pentium 4's out there now have 1 MB of cache, and the latest ones have 2 MB! This is either 4 or 8 times as much as the Celeron, and this translates to ASTRONOMICALLY HUGE performance increases! Every single thing you do on your computer becomes faster with more cache, and this is the number 1 reason why the Celeron is a slower performer when compared with an equally clocked Pentium 4 (and it's also one of the main reasons the Celeron is so much cheaper!). Lastly, the internal instruction programmed into the processors themselves are different. All currently produced Pentium 4's support a technology called "Hyper-Threading". Currently, processors are only able to process one thread (or instruction from a program) at a time. Hyper-Threading allows the Pentium 4 to process 2 threads at a time. In theory, this means it is twice as fast. But hold on, it's not as simple as it sounds. If you go onto a computer that has Hyper-Threading technology and look at the Device Manager, you will notice that there are 2 processors. If you look at the Task Manager, you will see 2 CPU's. But there really aren't 2 processors. One is virtually, and unfortunately it is hardly ever taken advantage of. Multi-threaded applications are not dominant in the market. Most everything out there is written for single-threaded processors because manufacturers don't expect a majority of the computers out there to have processors that can handle more than 1 thread at a time. Therefore most applications see no performance gain from having Hyper-Threading. However, those applications that DO support multi-threading will take advantage of the Pentium 4's technology and the performance is awesome! The Celeron would never be able to take advantage of that, and programs that are written for multi-threading are usually processor-intensive programs, and those types of programs perform sluggishly on processors with little cache. The definitive answer is that the Pentium 4 is by far the better processor, but with quality comes the price. If performance is what is driving this question, undoubtedly choose the Pentium 4. If price is the deciding factor, TRY to go with the highest-priced Pentium 4 your budget allows and if all else fails, get a Celeron.

Basically Intel and AMD are rival processors. They both are same in capability. AMD is new in market, so no one is aware about its capacity. But Intel is quite old one which has gained much publicity and trust in people. I heard AMD is more  powerful than Intel processors. \n\nIf you want to use computers for high end job like graphics design, 3d, animations then i recommend Intel Pentium. If it is for normal use like Office, emails n nets then Celeron would do for you.

athlon 64 is a 64-bit processor with only one core and pentium d is also an 64-bit processor but with two cores on one die. Simple enough...

A pentium 4 is a single core single threaded processor. This is the normal kind of processors we have been seeing for a while now. \nA Dual core actually contains two (nearly) independent processors in a die i.e. it is as good having two processors on one chip. These chips typically have a lower frequency rating. But they are designed to provide higher throughput. \nHT stands for Hyper Threaded. In technical jargon called Multi-threaded, this processor gives a notion of two processors even the most of the individual components of the processor are shared. (The Functional Units are shared. My understanding is that Pentium 4HT implements coarse grained multi-threading, so the pipeline is the same but the register file will be duplicated.)\n\nWhich one is better depends on the kind of application you are looking at.

The new Pentium D (the 900 series) is a processor by Intel in which there are 2 physical cores. Each core can run one thread, allowing you to run 2 threads at the same time. Here's an analogy. You have one door, and 1000 people have to fit through. Now, you have two doors, and the same 1000 people have to fit through. Assuming all the people are the same, they will move faster through two doors than through one. This is what the Pentium D essentially is, allowing you to run more than one process at a time (two specifically). The Pentium D 900 series gives 2 MB of L2 Cache per core (so a total of 4 MB) and is built using the 65 nannometer process. If you get a decent motherboard, you can overclock the Pentium D 900 series processors quite a bit, as they don't produce as much heat as the rest of Intel's processors. This is the second version of the dual core processors from Intel, as the first series were the Intel Pentium D 800 series. The Pentium D 900 series are far better, with lower temperatures, more cache, faster speeds, and much better overclockability.

Guys.. there is nothing like best... it all depends upon 'your objective' ie your requirements decide the best. Intel offers CPUs in two brands - pentium and celeron. if you've more money, then you could go for pentium. celeron is low-cost processor and it does effective than pentium. Another one is AMD's Athlon its all so cheap and faster. My opinion falls on Athlon.

There is the P4 which has many different versions such as the Pentium M (mobile cpu - centrino), the core duo, the Xeon, the standard P4 which ranges from a 400mhz bus to an 800mhz bus, and then the Pentium D which is the dual core CPU.\n\nThe very top chip I think they have on the market right now is the Intel Pentium Extreme Edition which is a dual core chip with 2x2mb of cache and a 1024 bus.\n\nAs for the AMD, there is the sempron which is AMD's answer to the celeron (but better IMHO) and then the Athlon 64, which is a pretty awesome chip, but not as awesome as the AMD Athlon 64 X2 which is the dual core version of the AMD line.  The opteron is the name of AMD's server chip line, and they do come in both single and dual core.  Then, of course, is the Turion CPU which is the mobile chip.\n\nI like both chips, I usually sell more AMD than INTEL chips.  You can pick up a dual core AMD Athlon 3800+ X2 for around $300 and it runs sweet when paired up with a gig or two of RAM.\n\nHope this helps!

windows xp home and professional support hyper-threading. you need an intel pentium processor that supports it. celerons do not have it amd processors do not have it. and i believe the regular pentium d's (dual core) dont have it (the extreme editions do). u will know if u have hyper-threading by bringing up the task manager (alt ctrl del) and clicking the performance tab if your cpu graph is split then u have hyper-threading enabled (2 graphs per cpu or core)

Software that is written to take advantage of a dual-core processor will allow both cores to work together to complete a task. You won't get true 6 GHz performance, but it will be significantly quicker than if you were running a single core 3 GHz processor. One complaint about the Pentium D chips is the two core use the Front Side Bus to talk to each other, therefore, the processor speed is limited when the two cores are working together. I'm running a Pentium D 830, and aside for an increase in my electric bill, I'm happy with it's performance.

None better because each processor, AMD and Intel Pentium, has each benefits but usualy AMD cheaper than Intel Pentium so if you choose AMD you can get processor with performance as well as Intel Pentium with less cost.

Basically, Celeron this the cheap-ass processor.  Celerons are the lowest of the low with slow speeds, higher crash rates, and basically only enough power for a user of only e-mail, internet surfing, and pinball...nevermind high-graphic games like Quake 4 or Sims 2.  Centrino processors are built specifically for laptop computers so they are great on power consumption and heat (or, less heat, for that matter).  The Centrino processors also have WiFi capabilities (wireless interet/networking, as long as you have a router at home or are in a WiFi-enabled building (e.g., certain Starbucks coffeeshops).  Go with Centrino, my friend!, hands down.

Here are the most important similarities and differences between the Pentium 4 and the Celeron chips coming out today: \nCore - The Celeron chip is based on a Pentium 4 core. \n\nCache - Celeron chips have less cache memory than Pentium 4 chips do. A Celeron might have 128 kilobytes of L2 cache, while a Pentium 4 can have four times that. The amount of L2 cache memory can have a big effect on performance. \n\nClock speed - Intel manufactures the Pentium 4 chips to run at a higher clock speed than Celeron chips. The fastest Pentium 4 might be 60 percent faster than the fastest Celeron. \n\nBus speed - There are differences in the maximum bus speeds that the processors allow. Pentium 4s tend to be about 30 percent faster than Celerons. \nWhen you sort all this out and compare the two chips side by side, it turns out that a Celeron and a Pentium 4 chip running at the same speed are different beasts. The smaller L2 cache size and slower bus speeds can mean serious performance differences depending on what you want to do with your computer. If all you do is check e-mail and browse the Web, the Celeron is fine, and the price difference can save you a lot of money. If you want the fastest machine you can buy, then you need to go with the Pentium 4 to get the highest clock speeds and the fastest system bus. \nalso u can check out this site for more info:\nhttp://computer.howstuffworks.com/question268.htm

Pentium 4s are the current top-of-the-line Intel processor, the Centrino is used in notebooks and has built in wireless capability, Celerons are considered budget processors.  For example:\n\nA Celeron at 3.2 GHz will run slower than a P4 at 2.66GHz.  This is because the Pentium processor performs more work during a clock cycle.  However, Celerons are more highly overclockable and can actually be decent processors.  There are P4s, the P4s with HT, the 64-bit P4s, the p4 dual cores (extreme), and the PentiumD dual cores.\n\nCentrino is not the name of a processor or a computer, it is the name given to the combined technology within the chipset and processor of a notebook PC.

Assuming you could find a P4 running at that speed (the fastest P4 Intel released was 3.8 Ghz based on a Prescott core, with the next fastest being a 3.73 Ghz P4 Extreme Edition), the processor would be, in absolute terms, faster than that Pentium M, but it would be consuming radically more power to provide that computing capability.   Pentium M is much more power efficient than Pentium 4, as measured on a "performance per watt" basis, the new standard Intel is using for designing microprocessors.  Because of this new focus on performance based on power consumption, Intel is dropping the Pentium 4 core from future processor development, and all new Intel CPUs will be based on Pentium M technology.

Any motherboard running an Intel 915 chipset or better. There are some Intel 865 boards back on the market but they are not as good as the 915, 925, 945, 955 and 975 chipsets.\n\nMotherboards in the budget region of hte market will work as well but they will affect your performance negativly, yes i am refering to boards using the VIA and SIS chipsets (they are okay for celeron D but will also negativly affect the performance of teh already bottle necked celeron D). \n\nIf you need some thing on the cheap side for an intel pentium 4 or Celeron D then go for an Intel Grand county motherboard with an ATI xPress 200 chipset.
