Is there any remarkable difference between 32 bit & 64 bit proceesors with regard to performance
In the future, the battle between 64 bit vs 32 bit processors will inevitably yield the 64 bit processor as the victor, but this transition is going to take some time.
First, Iâ€™ll talk about the pure mathematics and structure of the processors that are involved here. Iâ€™ll keep this part short and sweet.
A bit is short for â€œbinary digit.â€? It is basically how a computer stores and makes references to data, memory, etc. A bit can have a value of 1 or 0, thatâ€™s it. So binary code is streams of 1â€™s and 0â€™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 wasnâ€™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 doesnâ€™t fall into that category will see some benefit of using 64 bit processors over 32 bit processors, but not much in todayâ€™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 werenâ€™t written to take advantage of the extra power, they wonâ€™t use much of it.
The true benefits of this set up donâ€™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 wonâ€™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 computerâ€™s hood.
So, the question now is should you buy a 64 bit processor now, or wait?
Youâ€™re currently not able to take full advantage of the technology because the software vendors havenâ€™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.
Better performance out of a 32-bit operating system.
Probably the last processor youâ€™ll have to buy for many years to come
I bought AMD Athlon 64 3200+ for 9.5K, and i m happy.
The performance difference will be more evident when u use a 64bit OS running programs that are 64bit compatible ....
how many of u users on 64 bit actually know the difference ?
the difference in technology ? the difference in working ?
i mean most of the ppl with 64 bit proccy's are still using 32 bit operatin systems
what is ur benchmark ? plz do tell
the point is not if 64 bit will catch on and if it has a future
cuz 64 bit IS the future
the point is just whether u should upgrade yet or no ..
answer: what i think ? HELL NO!
till there is a proper OS and also loads of normal applications to choose from theres no point in upgrading to 64 bit
not till next year
so what abt future proofing ?
cmon we all know no computer is future proof beyind one year
a very good example ... C**P magazine august issues 2004 and 2005
built the best PC money can buy ... see the difference in specs and current prices
Well, windows xp 64 bit has been released! Its not in beta! Other OS's in 64 bit: Windows Server 2003, Fedora Core, Suse, Ubuntu...
And i can see that at least 40% of the current programs that you might have are available in 64 bits. As for the remaining 60%, you can find good alternatives that work great on 64 bits.
I have AMD Athlon64 2800+ the only reason i still hae XP 32 bits on my PC is that im not able to find a 64 bit driver for my graphics card (ATI RAGE PRO).
There is no point in spending the extra bucks in a 64 bit system right now.
I hve Recently bought AMD sempron 64 bit 2500+ it is low cost good performance processor,
You can go for this one. Also if you use 64 bit OS's Like Ubuntu Hoary AMD 64 then the Performance increase will be clearly visible while working with various applications....
Heard abt WinXP 64-bit. Can any1 gimme its price.
I dunno the exact price, but it is same as that of Windows XP 32 bit. In fact, you can exchange your 32 bit Windows XP for a 64 bit Windows XP for free!
Is the new Vista a 64 bit OS or its also 32 bit.
Vista will be available both as 32 bit and 64 bit.
Vista will be available both as 32 bit and 64 bit. But it will not be available on CDs only DVDs!!!
no problem with dvd. wat's da price?
Ya Where can I buy Windows XP 32 bit or 64 bit legal version in India.
If possible can I buy online ? Where ?
Can anyone tell me the price of intel 64 bit processor ---IntelÂ® PentiumÂ® 4 Processor with HT Technology Extreme Edition 3.73GHz (64 Bit : EM 64 T)
What is the OS you are using?
Are your Video files are working fast enough?
I don't think Windows xp 64bit is released as yet to fully explore the potential of a 64bit processory. Till then, its all the same...
Remarkable difference - definitely not.
In fact you should expect a performance hit (upto 5% according to MS) if you try to run 32 bit software on Windows 64 Bit.
You will need a 64 Bit OS running software written bottom-up for 64 Bit technology to observe ANY difference at all.
1)WinXP 32bit. (Drivers for my mobo are still in beta stage for XP 64 bit), and Fedora core 4 64 bit.
2) ru asking for the speed of video encoding?Yes they r pretty fast.
