64-bit XP system officially appeared
About half a year ago, when AMD officially announced its 64-bit processor, Microsoft vowed to launch 64-bit version of the operating system as soon as possible. Although AMD's 64-bit processor is compatible with 32-bit systems and programs, everyone knows that there must be a corresponding 64-bit software program support for 64-bit computing performance. Otherwise, the 64-bit is only the improvement of the product word.
Last week, Microsoft officially provided a Windows XP 64-bit Edition beta download version of the 64-bit handling amount of AMD in its official website. Also, anyone can get this non-commercial version of the test system, which is only free to use 360 days and fill in your true registration information.
What is the change?
In the first time, we downloaded this Windows XP 64-Bit Edition operating system and installed in the AMD64-bit processor environment. The process of the entire installation and the process of installing 32-bit Windows XP operating systems are exactly the same, and the difference is the change in the startup screen and the bundled software has been upgraded.
Although there is a 64-bit operating system, it is difficult to determine the direct change of 64 bits on the surface due to extreme lack of 64-bit applications. It is difficult to find a 64-bit hardware driver, which is more difficult to directly understand the pleasure of 64 bits from some peripherals or multimedia applications. However, this Microsoft's 64-bit Windows XP version is designed specifically for AMD's ATHLON 64 or OPTERON processor, so the program with test CPU performance can find some 64-bit programs.
In the test result, we found that the 64-bit operating system role in 64-bit calculations. Although it is difficult to determine the difference between 64-bit and 32-bit programs from the calculation results, we have significantly experienced the operational effects of 64-bit calculations during the program calculation - the increase in calculation efficiency.
Among them, the test results of 32-bit programs in the 64-bit operating system are not as good as performance in the 32-bit operating system, so that our performance of 64-bit operating systems is compatible with 32-bit programs. It is also proved that the 32-bit test program is currently circulated online, and the game performance under the 64-bit operating system will be reduced.
64-bit program reveals value
Now, for 64-bit computing applications, except for large enterprises, others are still almost zero, and the 64-bit application market has not started. But in theory, from this Microsoft published 64-bit operating system version combined with the AMD 64-bit processor test, we already feel the infinite value of 64-bit programs in some 64-bit test programs. - Running efficiency is greatly improved.
Before 2003, when we talked 64, you might say that it was just a dream; when we talked 64 times, you may say: "Let's wait, now there seems to have only AMD family. "Now, when Microsoft is officially raised up this 64-bit banner, you should believe that a new market door is slowly open. We believe that software developers have greater in this regard, and the new batch of "64 heroes" will be born.
64 digits
The so-called 32-bit and 64 bits actually refer to the computer's addressing space size, which is how many calculation operations doing memory under a clock frequency action. 2 of 5 times is 32, while 64 is 64. For binary computer operations, the number of addressing bits has increased, and performance can be greatly jumped. Just like 286PC is 16 bits, the performance change of 32-bit transformations of 386.
In the history of computer technology, the evolution of central processor addressing spaces often affect the development of the entire computer. In 1975, the 8080 processor's emergence of 8 addressing capabilities created Bill Gates and Paul Allen out of school for ALTALR computers. In 1980, the invention of the 286 chip directly gave birth to the birth of a personal computer. 16 addressing capabilities determine today's 640KB basic memory today; the 386Dx chip is born, 32-bit computing power creates complex graphics interface, so that we bid farewell to dark DOS programs with beautiful Windows And 32-bit calculated outstanding representative Pentium chips, which promoted the development of the entire multimedia PC era. Continuing this development path, 64-bit addressing spaces coming, undoubtedly announced that both Popular Computers will develop in terms of high performance. 4GB memory is still a bottleneck for installing a 32-bit processor computer, as it is small in addressing and coding, only for low-end, small-scale applications, once business development and data exceeding 5 million daily, the system is It is easy to fail or even collapse. The 64-bit platform up to 18 billion GB of memory addressing capabilities, allowing it to solve the bottleneck addressed in high-end applications in the future.
In short, from various numbers, 32-bit to 64-bit, a revolution with improved computer performance!
