What are the advantages and disadvantages of 64bit & dual core processors?

64 bits:\ngood:  application that is developed in 64 bits have a wider range of value, larger memory handling => faster and more, well 'colorful'.\n\nbad:  nothing bad about it, but currently, there is not much application written in 64 bits, and not likely comming soon.\n\n\ndual core vs single core.  \nThis is a no brainer, it's like compare 1 computer with 2 computers.\nThe main difference is that single can do 1 thing at a given time, while dual core can do exactly 2 things at a given time.  So take a guess of what advantages and disadvantage.\n\nThere are few things you like to know.  That having a 64 bits Cpu Do Not make your computer run faster.  \n\nSay, you have a two identical 64 bits system (cpu), and system A installed XP, system B install XP 64.\n\nThe different is B will boot faster than A, and probably some Microsoft applications in B run faster than A. \nBut if you have Photo shop in both system, they will run at the same speed.  why? because Photo shop is 32 bits application.  \n\nPicture this, to transport 32 people with 32 seat bus and 100 seat bus, which is faster?  You wouldn't gain much from 2 options do you?  because 32 bits application just simply use only 32 first bit of instruction code, and left the other 32 bits empty.\nJust like the 100 seats bus.

definitely intel core 2 duo...but if u r willing to wait a while opt for intel quad core....also to get more info on the processors try google...type.....''benchmark: Name of processor''\n\nin the market intel dual core and core 2 duo are available...but remember that dual core has only 1 processor and the other is a logical unit, while core 2 duo has 2 physical processors

As far as servers are concerned, yes.  I know that the AMD Opterons are.  However for desktop processors the Intel Core Duo which has made its debut in the Intel iMacs and MacBook Pro are dual core but are not 64-bit processors.\n\nIf you are getting servers, do with an AMD Opteron.

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.

At the moment, it is doubtful if a dualcore will make much difference, since most software still needs to be rewritten to use both cores.\nOn the other hand: I have installed a dualcore about a month ago, and I do notice that when I have certain programs running which cause a heavy load on one of the cores, the other core is still available, thus keeping my system running more smoothly and allowing me to do more with it at the same time.

having a dual core processor will not boost the performance. Dual core was designed for Multi Processing i.e decoding video and playing a game at the same time. \n\nmy advice is for you to notice the front side bus of the processor ( the more the marrier ) the cash memory of the processor, the Clock speed of the processor ( which people usually call processor speed ). also there is a big wieght on Ram and VGA card. when you lag in game, its not usually from the processor, its from the VGA card or memory. specially when in dust/fog environment. \n\nif you need more info on what to decide, refer to http://www.tomshardware.com\n\ngood luck

pretty good it is fast and good for multi-tasking but i would get the turion 64 X2 that is the dual core one and also get 64 bit so that you can update to Windows Vista it takes less battery the the athlon 64.

I am currently putting my new system together.  I settled on the AMD64 X2 because I could take advantage of a dual core processor ( I use linux exlusively). I haven't looked at the pentium D so I could not comment or make a comparison.  I have built a few AMD's and a few pentium 4's .  I find the AMD 64's  more responsive and a better bang for the buck.

its got a dual core. 2 cpus in one ( some thing better than hyperthreading

AMD is better cos they are usaully 64 bits where as celeron are 32bit

This is not a choice.\nDual core are (usually) capable of 64 bit.\nIt's like asking "What's better, a Rottweiler or a dog?"\n///

Pentium D is way faster then P4, however alot of software does not suppor the dual core, so its basically same as P4 Unless ur software has support for that.

The Turion has 2 x 256kb L2 cache.\nThe Core 2 Duo has 2 x 2048kb L2 cache.\nBetter battery life in the Core 2 Duo\nno applications to run on the 64 bit as yet.

Dual core processors help only if you are using multiple programs at once. For example, if you are editing a photo image in Photoshop that can take a long time to do a task, you can still run a music program at the same time without major problems. Most computer owners will not benefit much, if at all, from having a second processor. Some programs may be able to use both processors at the same time to speed itself up, but I do not have much information on that point.\n\nEdited to respond to a post later on: hard drive speeds can make a difference, but only a little. The most of the "speed" of a computer has to do with the processor speed, RAM size and speed, and the motherboards' bus speed. Hard drive speeds only really account for data retrieval or saving of data, and these days they do not play nearly as big a part in computer speed as they used to.

I'm strated too. The x64 version has problems executing some 32-bit (and 16-bit) programs. That's why its mostly used on servers and not home computers?!

Given that the prices are the same,there are two other really important issues that you need to look at-performance and battery life.If you need higher performance,mobility,graphics,games and aren't away from a poer source for a long time,I would suggest that you go with the AMD Turion64 X2.My dad's is an Acer Aspire with AMD Turion64.Its not dual core,but I've really felt the upbeat in performance when compared to the Intel centrino series.But the problem persists in the battery life.The standard 6-cell Li-Ion Acer battery gives about 4-4.5 hrs in standard conditions when used with Centrino.The same battery is found to last only about 3.5hrs when used with AMD Turion64 processor.But since I wanted performance at any cost,I opted for this 64-bit beauty.\nIf its battery life that you need,I suggest that you go with the Centrino Duo series.This processor gives you a good battery life.\nThe difference between a 64-bit processor and a 32-bit one is that 64 chunks of data can be processed by a 64-bit processor in one go,and the other can only handle 32 chunks of data at a time.The AMD Turion64 X2 is a 64-bit processor.But the Intel Centrino Duo isn't.If you are indeed waiting for a 64-bit Dual Core solution from Intel,I suggest that you wait for about 2 months or so.Intel's Centrino Duo 2 is a dual core 64-bit processor with the second core about 30% faster.But since the performance characteristics of this isn't known,there's little that I can comment on.\nI hope that answers your question.

The AMD64 architecture gives you the best of both the 64-bit and 32-bit worlds. That's because, depending on the operating system that you load, an AMD64 processor can run both the "classic" 32-bit versions of Windows, such as Windows 2000, Windows XP, or Windows Server 2003, or it can run the special 64-bit extended versions of Windows XP and Windows Server 2003 that Microsoft is currently beta-testing. \n\nThe real flexibility comes when the processor loads the 64-bit version of Windows; in that mode, called Long Mode, the computer can run both 32-bit and 64-bit Windows applications at full hardware speed. The backward compatibility with 32-bit applications is provided by the AMD64 processor on the hardware side; the operating system handles 32-bit calls by using a special technology called WoW64, for Windows-on-Windows 64, that translates 32-bit pointers and arguments into 64 bits and back again. \n\n(A 32-bit application can find out whether it's running under WoW64 by calling the IsWow64Process function.
