The difference between 64 and 32 bit processors

A bit is short for “binary digit.” It is basically how a computer stores and makes references to data, memory, etc. A bit can have a value of 1 or 0, that’s it. So binary code is streams of 1’s and 0’s, such as this random sequence 100100100111. These bits are also how your processor does calculations. By using 32 bits your processor can represent numbers from 0 to 4,294,967,295 while a 64-bit machine can represent numbers from 0 to 18,446,744,073,709,551,615. Obviously this means your computer can do math with larger numbers, and be more efficient with smaller numbers.

Now see, that description wasn’t too bad, but the question is how does this affect you, the average PC owner? The largest benefit will go to academic institutions and private companies, where large calculations are being performed, huge databases are being accessed, and complex problems are being solved.

Everyone that doesn’t fall into that category will see some benefit of using 64 bit processors over 32 bit processors, but not much in today’s marketplace. The AMD Athlon 64-bit processor is completely backward compatible, meaning you can currently use it with 32-bit operating systems and software programs. You will see some benefits by using this setup, but because the programs weren’t written to take advantage of the extra power, they won’t use much of it.

The true benefits of this set up don’t come from the amount of bits, but by the improved structure of the 64 bit vs 32 bit processor's older structure. A 64-bit processor is made with more advanced silicon processes, have more transistors, and faster speeds. This is currently where the true benefit of switching to a 64-bit processor lays.

As for 64-bit operating systems and software, many are in the works, but nothing is in final version. Microsoft has released a beta version of Windows XP that takes advantage of the 64 bit technology, but there are still issues. The problem is when you run 32-bit software programs in the environment of a 64-bit operating system. Many programs won’t work properly, such as Adobe Acrobat and Windows Media Player, for example. Another issue is RAM. You really need about 4 GB of RAM to take full advantage of the capabilities offered by a 64-bit processor, while most PC owners have less than 1 GB under their computer’s hood.

So, the question now is should you buy a 64 bit processor now, or wait?

Disadvantages:

You’re currently not able to take full advantage of the technology because the software vendors haven’t made the switch from 32-bit to 64-bit processors.


Most AMD Athlon 64 bit processors are expensive, with prices sure to go down in the future.

Advantages:

Better performance out of a 32-bit operating system.

32bit Vs 64bit

athatama mama danna widiyata deke wadi wenasak na. mokada 64bit processor thibbata madi. 64bit software dannath one. anika 64bit processor kiyanne 32bit processor 2k ekata run wena eka. ithin speed eka ekai. eth eka para godak wada karanna puluwan. mokada wada processor deken bedagena karanne. 32bit eke okkoma karanne eka processor eka ne. ithin ekai eka tikak slow wennath 64bit eka fast wennath hethuwa.

UF., Gampaha.
main difference between them are most of software + all drivers don't support for 64bit unless you haven't unique 64bit software.

(( for me, I don't have Drivers for my LankaBell's Huawei dialup modem & I gave up 64bit till I get Broadband or something :lol: ))

    If you have a 64bit processor ...64bit Windows version will give u much better performance than 32 bit windows on a 64 bit processor :) i tried it and it is fast than 32 bit.....but...Softwares are mostly 32 bit..so less Sofwears for you in 64 bit

    Im asked this because im going to try it . i have core 2 duo procecer which support 64bit . im currently running on windows xp 32bit . and i will install vista 64bit edition and gonna try it .

    If you have 64bit versions of the applications you use then go for the 64bit OS.
    Other than that if you have 4GB or more ram then go for 64bit.

    Mama 2 kama use karanava.
    64 bit vista and 32 bit vista ultimate.

    For games i am using 64 bit vista since it uses my full 4gb ram.32 bit uses only 3.25 of my 4 gb ram.

    There is no actual speed difference between both.specially after you install SP1

    machan, api (means my office) pawichchi keranawa 64bit technology eka ape work stations walata, but all custom made OS and SW. 64bit godak relay wenna puluwan eka paarata godak calculations keranawanam... hariyata loku data set ekak (more than 1Gigs per second ) wagee process keranawanam 64bit worth. But if you having Xeon quad Core dual processor work stations thiyenawam, oogollanta scientific calculation keranna oonenam, real time 3D graphics generate keranawanam 64bit hondai…. ehema nethinam 32bit hondatama ethi... according to my knowladge for PC's it not worth coz its expensiv and toomuch perfomance consuming.

    I already used 32 & 64 bit win.xp OS , so nothing special between speed of them.
    but if you wanna work with 64 bit programme , you should switch to 64bit OS , otherwise there is no point in your installation.

    but it is better to know , in 64 bit architecture environment , 64 bit programees including OS works under its maximum performance ( maximums speed ). 32 bit programmes works with as they works with 32 bit architecture environment , under 64 bit

    So , If you have 64 bit processor . its better to install 64 bit OS + 64 bit programmes to obtain maximum performance...

    :cool: :cool:

    In simple...

    Under 64 bit processor...

    64 bit OS + 64 bit programmes = 100 % CPU performance

    64 bit OS + 32 bit programmes = < 100 % CPU performance

    32 bit OS + 32 bit programmes = < < 100 % CPU performance

    note .

    "performance" not equals to "Usage" , but the prob. is How to find 64 bit programmes....?:dull: :dull:

    64bit Os ekaka 32bit Programmes Use Karanna Ba Neda ? :D
