Is Pentium M better than P4s, which one is faster?
80142
Intel's Pentium M (m is for "mobile") and P4 are different style chips, so it is difficult to compare them on clock speed alone.  \n\nWhen I purchased my laptop (two years ago), I did some research on this topic.  The claim at that point was that the 1.6 MHz mobile was about the same as a 3.5 MHz P4.  This may have been in PC Magazine or something online.  (Can't find the source quickly.)\n\nThe main thing is that the M chips suck less energy, which is good in laptops, where battery life and heat are more important.

There's no such thing as a Pentium 4 M! There's a Pentium 4 and there are Pentium M and Celeron M Processors. There is also a Pentium D and celeron D. If you want to know more about Intel processors go to the link below.\n\nEach chip has been designed to capture different parts of the market. The Pentium M is for laptops and primarily is designed to run a lot cooler because of confined spaces and to extend the life of the battery. This is the better CPU for a laptop. You can get the P4 in laptops but they weigh more and the battery rarely lasts more than an hour before you need to charge it up again.\n\nCeleron chips are cheaper but there's a reason for that :-)

It depends on wat kind of applications u work on. Dual core is good if u want 2 use multiple applications at da same time. It wont giv u any more advantages,it takes more power & more money from ur pocket.I say u go with Pentium 4 3.2GHz, coz its more faster & less power using dan dual core.If u want u can also buy AMD FX 57. Its very good & IC Chip(The best comp magazine) rated it da best proccessor. U can buy dat if u want. But if u still want intel, u buy P4 3.2 GHz

dual cores are best for multitasking and p4s are best for gaming. \n\nif you dont already have a pentium motherboard though, please consider getting an AMD brand instead. they are cheaper and less resource intensive.

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!

A Celeron processor is cheaper than a Pentium, but at the cost of speed. It is slower, but cheaper.

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.

well that is a nice question but the main difference is that with the dual processor, it enables your PC to respond faster to multitask and it does so a speed of as fast as you can multi task the computer. As fast it you can be multitasking the PC, so fast will it to respond to all the tasks at a glance. and that is the difference between the dual and that of the P4.\nMoreover these are the features of D processor\n1.Revved up multitasking\n2.Built for advanced applications\n3.Multiply your multimedia experience\n\nPentium D processor-based PC allows two people to share the content from one PC - in the same room, or even from different places in the house. For example, one person can be checking email while the other uses a remote control to access digital photos stored on the same PC and view them on the TV from the comfort of their living room. \n\nHope you are ok with this. We will talk more later

You're buying a loptop, so power use will be important to you. Batteries life is terrible with high power components, including the CPU. \n\n=======\npower\n\nAnd that's the first distinction. The Pentium M was designed for minimum power consumption in a Pentium compatible CPU. So your batteries will last longer. \n\nThe Duo Core CPUs are really two CPU cores in one chip. IF the operating system, and application design (which you can't affect) support them properly, such a CPU can be much faster than a single CPU, all other things being equal. But the Duo Core chips use more power, so your battery life will suffer, all other things being equal. This may be worth it, if you are doing computationally intensive stuff, and if your software / operating system can take advantage of the additional CPU. Otherwise, it will make little difference. \n\n========\ngraphics performance\n\nOne computationally intensive use that's common is gaming. it takes a good deal of effort to calculate color brightness and shading for each pixel in a scene, and there are lots of scenes. In fact, it takes so much computational power that vendors have largely given up on making the CPU 9or CPUs) do it all. Recent graphics schemes, the ones that make game images snap and sparkle, during play require a lot of work from some processing chip. The best of the graphics processor chips have more computational power than nearly all CPUs, and they require comparable electrical power (draining batteries still more quickly). It's this reason that accounts for laptops rarely having cutting age graphics performance or CPU speeds. In particular, the graphics hardware in most laptops has low power needs and is hardly up to recent graphics performance standards. \n\n==============\nCPU architecture differences\n\nAnother issue, which will matter only if your use of the laptop needs it, is differences between various Pentium editions. Intel has added more instructions, and used different internal architectures, as they have designed new CPUs. These include new instructions (the SSE, SSE2, etc groups) and the 64 bit EM64T additions to the basic 32-bit core, in emulation of AMD's Opteron and AthlonFX approaches. But for the moment, until your applications can use those extensions, and until your operating system is fully 64-bit compatible, your EM64T CPU will be running mostly in 32-bit mode. And recent Pentium 4 CPUs have included something called Hyperthreading which speeds up some kinds of programs substantially. And, of course, various Intel CPUs have included more or less fast cache on the CPU chip itself. If this is done sensibly, cache (and more cache) can have dramatic effects on many kinds of program execution speeds.\n\nDepending on detailed comparisons between the CPUs you're considering, some (or none) of these differences between CPUs might be significant to you. See Intel's spec sheets for the CPUs you're looking at for the differences. \n\n\n\nIn your case, since you aren't a gamer, the merely adequate graphics hardware in most laptops will probably be acceptable. Your mention of graphics programming might mean image manipulation, and either CPU should do in that case. Photoshop and similar programs don't have to handle graphic manipulations in real time, and so their demands are much less for satisfactory performance than video (or near video -- such as games) processing. \n\nWord processing simply doesn't have so high requirements. After all, any CPU sits doing nothing for eternities between key presses, even for fast typists. There's lots of available cycles from most any CPU in most any word processing operation. \n\nSo, for you, which would be better? mostly, it depends on the work you'll be doing and the applications with which you'll be doing it. If they can take advantage of the processor features in one or another CPU (not something you can easily find out, probably even from the software de

1.6 ghz AMD turion 64 X2 has two 1.6 processors inside. Dual core processors handle multi-tasking better if you're running mulitiple programs on a Pentium 4 it's going to slow down. If you run it on the dual core processor it will run smoothly. \n\nRunning one program at time 2.4 P4 processor would beat 1.6 dual core. 1.6 is kinda slow I have 1.83 core duo processor. I paid $1200 for my 15.4" labtop. Now there are core 2 duos which are faster than the core duo so I recommend getting a labtop with a core 2 duo or at least what I have because it's pretty quick.

as an example if u have p3 the internal speed of the ram is 133 Mhz , and for P4 is 400 Mhz or 800 , that means all parts shall be compatible to each other in order to get best performance , also memory will go in double capacity , 128, 256,512,1028 , u cant add 128+512=640 its not really wrong but how money can the add memory worthy

The fastest pentium IV is actually 3.8 ghz.  They passed 2.0 ghz a long time ago.  Now they have dual core proccessors from Intel and AMD.  The one from intel is called pentium D.

Core - 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\n\nBut yes you should have no problem running a game needing a 1ghz processor with a 2ghz celeron processor.

the pentium 4 3.2 comes in 2 versions 540  and 640 the difference is the l2 cache the 540 is 1 mb the 640 is 2 mb both have HT technology hyper threading to get a dual core (2 processor) you need to buy a 840 or 940 pentium D

Intel is faster but AMD is a LOT more reliable!...it's not all that much slower at all....we're talking nanoseconds here!\n\nI have several AMDs, different ones and had a Pentium 4 FRY. The Pentium I'm on right now seems to be ~ok~, but I still like AMD a LOT better.

I think I understand what you are saying a little better than the other people.  You are looking at the 1.86Ghz speed and comparing that to Pentiums in the 3GHz range and saying, well wouldn't the Pentiums be faster.  The answer is no, because speed is no longer the only important factor.  The new Core 2 Duos are based on a much better architecture, which allows them to do a lot more work than the old Pentiums, even at a lower speed.\n\nKeep in mind, this is not because it is dual core.  The Pentium Ds were dual core, and some had clock speed of 3.4Ghz and stuff like that, but the Core 2 Duo would still be faster because of its better architecture.  Also, don't listen to the people who said to just double the speed because it is dual core, that is incorrect, it just doesn't work that way.

Just about everything.  But mainly games and high-end software like video editing, photo editing... anything that requires lots of horsepower.  The more cache a CPU has the more instruction it can store close (on) the CPU and it will excute everything faster.  L1 cache is the fastest and the AMD Athlon 64 3700+ (San Diego) has 64KB+64KB (128KB) of L1 cache and 1MB of L2 cache.  This varies among processors, Semprons have less and Athlons have more.  The same applies to Intel with the Pentium 4 and Pentium Ds, they have more and the Celerons have less.\n\nIt does matter.  See how slow a Sempron 3100+ is compared to a Athlon 3000+, despite the Sempron having a faster core, you will find that the Athlon 3000+ is actually and performs tasks faster than the Sempron.\n\nThis link might help you, http://www.computerworld.com/networkingtopics/networking/lanwan/story/0,10801,44333,00.html
