簡介:
After a very long beta process, the x64 OS family is finally complete. The
release corresponds with windows server 2003 SP1. While this operating system is
called Windows XP x64, don t be fooled, it s windows 2003 under the hood. It looks
and feels like Windows XP but has a completely updated kernel. enjoy -WBi
Windows XP Professional x64 Edition is designed to meet the demands of customers
who require large amounts of memory and floating point performance in areas such
as mechanical design and analysis, 3-D animation, video editing and composition,
and scientific and high-performance computing applications.
Performance Benefits for Specialized, Technical Applications
The performance of 64-bit computing offers advantages in fields such as automobile
or airplane design, by allowing engineers to create larger, more complex models.
With such systems, engineers can use simulation software to analyze the effects of
airflow, stress, and heat on materials of a car or plane, and then study the results
to improve product design. Likewise, 64-bit computing is a benefit for digital
content creators, including 3-D animators, digital artists, and game developers who
can significantly reduce the time spent to digitally render three-dimensional
models. In the areas of scientific and high performance computing, Windows XP
Professional x64 Edition will aid in oil and gas exploration, seismic analysis,
computational fluid dynamics and scientific visualization among other applications.
全新的Windows XP Professional x64 Edition系統可以支持64位應用程序，可以使用更大的通用寄存器，其數量是傳統x86架構的兩倍，所以理論上可以提供更好的表現和更高效的數據處理能力。
　　第二，Windows XP Professional x64 Edition可以支持更大的內存，最大值達到32GB，虛擬內存的容量也可以達到16TB。而現在的32位Windows系統只能支持4GB內存，單一進程也不能分配2GB以上的內存，而新的系統將完全沒有這些限制。
　　第三，Windows XP Professional x64 Edition除了可以支持64位應用程序外，其也將向下兼容32位程序，所以用戶可以放心升級。據說這是微軟在其中使用了一個特殊的x86 Windows on Windows 64 (WOW64)模擬器。
　　盡管我們平常管支持64位運算的AMD處理器叫AMD64，而把Intel的叫EM64T（Extended Memory 64 Technology），但實際上這二者是互相兼容的，也就是說Windows XP Professional x64 Edition既可以支持AMD64也可以支持EM64T。
