what is the diffrente better 64bit and 32 bit
hi i am looking at this eMachine desktop solely for uploading and other small purposes, but it has a 64bit processor, should i get it? and also does it work with any program? what is the diffrente better 64bit and 32 bit.
Not sure about the difference between 64bit and 32bit, but my processor is:
ReplyDeleteAMD Sempron 3100+
1.80Ghz
1600MHz FSB
256 KB L2 Cache
with google I found this:
ReplyDeleteIn 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, I’ll talk about the pure mathematics and structure of the processors that are involved here. I’ll keep this part short and sweet.
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.
Probably the last processor you’ll have to buy for many years to come.
I think that you should buy it because u can run 32 bit and 64 bit programs (according your operating system), if you buy a 32 bit computer you won't be able to choose what kind of programs you can run. I have a 64 system and i almost never used the 64 bit capabilities, but i'm happy to have them. I think that my 32 bit operating system runs a lot better in my 64 bit pc what would run on a 32 bit pc.

ReplyDeleteA change from a 32-bit to a 64-bit architecture is a fundamental alteration, as most operating systems must be extensively modified to take advantage of the new architecture. Other software must also be ported to use the new capabilities; older software is usually supported through either a hardware compatibility mode (in which the new processors support the older 32-bit version of the instruction set as well as the 64-bit version), through software emulation, or by the actual implementation of a 32-bit processor core within the 64-bit processor die (as with the Itanium processors from Intel, which include an x86 processor core to run 32-bit x86 applications). The operating systems for those 64-bit architectures generally support both 32-bit and 64-bit applications.
One significant exception to this is the AS/400, whose software runs on a virtual ISA, called TIMI (Technology Independent Machine Interface) which is translated to native machine code by low-level software before being executed. The low-level software is all that has to be rewritten to move the entire OS and all software to a new platform, such as when IBM transitioned their line from the older 32/48-bit "IMPI" instruction set to 64-bit PowerPC (IMPI wasn't anything like 32-bit PowerPC, so this was an even bigger transition than from a 32-bit version of an instruction set to a 64-bit version of the same instruction set).
While 64-bit architectures indisputably make working with huge data sets in applications such as digital video, scientific computing, and large databases easier, there has been considerable debate as to whether they or their 32-bit compatibility modes will be faster than comparably-priced 32-bit systems for other tasks. In x86-64 architecture (AMD64 and Intel 64), the majority of the 32-bit operating systems and applications are able to run smoothly on the 64-bit hardware.
Sun's 64-bit Java virtual machines are slower to start up than their 32-bit virtual machines because Sun still assumes that all 64-bit machines are servers, and have only implemented the "server" compiler (C2) for 64-bit platforms. The "client" compiler (C1) produces slower code, but compiles much faster. So although a Java program on a 64-bit JVM may perform better over a long period (typical for long-running "server" applications), its start-up time is likely to be much longer. For short-lived applications (such as the Java compiler, javac) the increased start-up time can dominate the run time, making the 64-bit JVM slower overall.
It should be noted that speed is not the only factor to consider in a comparison of 32-bit and 64-bit processors. Applications such as multi-tasking, stress testing, and clustering (for HPC) may be more suited to a 64-bit architecture given the correct deployment. 64-bit clusters have been widely deployed in large organizations such as IBM, Vodafone, HP and Microsoft, for this reason.
