what is the difference between 32 bit and 64 bit processors?

its about transferring of data as we all know that data is used and while data is used it has to feed to the computer i.e input and result to be get backed i.e output so we need transferring of data the 32 bit processor say that it can transfer the data at a rate of 32 bits and 62 bit processor say that it can transfer the data at 64 bits.

the 4200 means 4.2 ghz comparable but that is hype,  to get the most out of a system you need fast memory DDR2 which AMD doesn't support yet, and a fast HDD  western digital Raptor 10000 rpm with a seek time 1/2 of the next competitor, the processor is just 1 part of the system, if you dont have enough and fast memory you will never get the max out of the processor,

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?!

each bit is a lane of traffic for data, like lanes on a highway.  The more lanes of traffic, the more data can flow at the same time.  HOWEVER, programs have to be written to utilize the 64 lanes or else they won't even try to go beyond using 32 lanes (for 32 bit programs). \n\n64 Bit systems are fastest available, BUT there are current limitations:\n1.  You have to use 64 bit operating systems and programs to fully obtain the benefits\n2.  Windows 64 bit edition does not support MOST older 16bit programs (Shouldn't be a problem for most people, but some people do have favorite DOS games or utilities or little applications that won't work anymore).\n3.  Hardware makers NEED to support 64 operating systems - you cannot use a 32 bit driver on a 64 bit operating system in 99.9% of cases (maybe 100%).  If your hardware vendor doesn't have a 64bit driver, you can't use the hardware or you can't use it at it's greatest level.\n\nFor NOW, I tend to suggest you stick with 32bit for broader compatibility.  UNLESS you have a specific purpose with specific 64bit programs.  In a couple of years though, probably with Windows Vista, when you decide to go to that, that's when you should probably switch to 64bit.

Athlon 64 Dual Core uses AM2 socket \nbut notmal Athlon 64 uses socket 939\n\ncheck what kind of socket you have on your M/B

XP SP2 is 32 bit and will run on all the (Intel arch. compliant) 32 bit Processors. XP 64 bit version will need 64 bit processors like AMD Athlon 64, AMD Opteron, Intel Xeon etc (but not 64 bit Itanium).\n\nso in effect generally XP64 version would be better than standard XP SP2.\n\nFor more information visit: http://www.microsoft.com/windowsxp/64bit/default.mspx

The P4 is a 32-bit processor, so you have a 32-bit system.

Faster, faster, faster!  64-bit technology!

There isn't a difference. It's just branding.\n\nThe technical nonbranded term is EM64T.\n\nOnly relavent when selecting a motherboard for a processor.\n\nAnd yes, Intel sells 64-bit proccessors, and was in fact one of the first to do so with their Xeon proccessors.

it doesnt mean the processor speed it has nothing to do with it. This processor has a 2.2 GHz processor. The 3500+ is just used to tell people its different from the older 3100+ version which is used on cheaper computers. For the 64, its an advanced AMD64 which allows the processor to run 32-bit applications at full speed while enabling 64-bit software applications.

I'd say it depends on what you need to do.  BUT, I prefer Intel processors for laptops.  Someone said that AMD processors run hotter than Intel, they do.  And AMD processors are not as power efficient as Intel when it comes to mobile processors.  That being said, AMD has a dual core 64-bit Turion processor for laptops.  This means you can run 64-bit applications but note that there aren't many, save for Windows x64 and some versions of Linux.  That being said, many programs are not supported under 64-bit environments, those that use 16-bit installers for example.  Most computers with 64-bit processors just come with Windows XP home or Pro (32-bit) which is fine and what I reccommend, only you can't run 64-bit programs in that case (again, not many out there).\n\nNow we come down to it.  It turns out that the Core Duo processors from Intel are faster and more efficient than the AMD Turion 64x2.  You decide, but I'm sold on Intel as far as laptops are concerned.  Note, I still prefer AMD when it comes to desktops because AMD desktop processors still crush Intel.  Intel has caught up in the mobile world, it'll be a while before I trust my desktop to one.

Contrary to what the previous poster said, there are advantages to 64bit processing. Sixty four bit processors, as well as applications and operating systems, have been around for years in the server market. The desktop market isn't the only computing market in the world.\n\nThe two MAIN advantages of it are that 64bit computing allows the use of more memory, as well as having thread sizes that are twice as large as those in 32bit computing.

it is a feature of the x86 series of the processors that allows upto 64GB of physical memory compatible to the 32bit processor based computers. provided there is a compatible operating system support. it is supported by most of the intel and AMD processors, there is an assinment of a CPU-ID flag for the purpose of the identification of the processors supporting the feature.

I would think the difference is that a 64bit would have a 64bit GPU and a 128bit would have a 128bit GPU.  The GPU is the graphical processing unit (the video card's own on-board processor), it's what allows video cards to do things like do your 3D graphics so your computer doesn't have to.  The 128bit probably would be better, but it might not be since bit-rate isn't the only factor in speed.\nLook at the following things:\nhttp://en.wikipedia.org/wiki/Graphics_processing_unit\nhttp://en.wikipedia.org/wiki/Bit-rate

64 has the potential to be better and faster and more secure.  Smart minds will stay with 32 bit until the 64 has been tested thoroughly and the major issues resolved.

From Microsoft.com:\n\nProcessor: 800 MHz 32-bit (x86) or 64-bit (x64) processor1 \nSystem Memory: 512 MB \nGPU (Video/Display): SVGA (800x600) \nHDD (Harddrive): 20 GB \nHDD Free Space: 15 GB \nOptical Drive: CD-ROM drive2 \n\n \n1) Processor speed is specified as the nominal operational processor frequency for the device. Some processors have power management which allows the processor to run at a lower rate to save power. \n2) The CD-ROM may be external (not integral, not built into the system).

With the 64 bit proccessor the motherboard you have choosen willo be problemmatic with the chip set, try going a little beter. With the Graphics Card try staying away from NVIDIA use Rage graphics cards there much better
