f you're looking for large amounts of memory and improved floating-point performance for tasks that rely on real-number data, such as mechanical design and analysis, three-dimensional (3-D) animation, video editing and composition, and scientific and high-performance computing, Windows XP Professional x64 Edition is designed for you. With its 64-bit processor, Windows XP Professional x64 Edition gives you access to greater amounts of memory while continuing to support 32-bit applications.

More memory, improved performance

The expanding data and performance needs of business, academic, engineering, and scientific organizations have pushed the limits and capabilities of existing information technology (IT) platforms. Millions of people worldwide need to access gigabytes or even terabytes of data in real time. The increasingly sophisticated demands for making home movies, working with digital photographs, using digital media, and playing 3-D games is also stretching the capabilities of existing 32-bit PCs.

Advances in processor technology that extend the capabilities of x86 architecture have brought the power of 64-bit computing to you. Now, you can use a 64-bit operating system to seamlessly run 32-bit and cutting-edge 64-bit applications. Windows XP Professional x64 Edition takes full advantage of this new architecture.

Comparing 32-bit and 64-bit editions of Windows

The major difference between 32-bit and 64-bit editions of Windows is memory support. With more memory, you can run more programs at the same time, and run more memory-intensive programs like multimedia, gaming, and database programs. And your computer's performance will be faster overall.

Currently, 32-bit editions of Windows are capable of supporting up to 4 gigabytes (GB) of system memory, with up to 2 GB of dedicated memory per process. Windows Professional XP Edition x64 currently supports up to 128 GB of RAM, with the potential to support up to 16 terabytes of virtual memory as hardware capabilities and memory sizes improve.

Another difference between 32-bit and 64-bit editions of Windows is the increased number of registers available on 64-bit processors. This enables faster performance for applications that perform intensive floating-point calculations.

Windows XP Professional x64 Edition provides faster performance, increased reliability, and greater flexibility to today's most demanding users. With Windows XP Professional x64 Edition, you can take advantage of the new 64-bit technology to improve your PC or workstation performance.

Windows XP Professional x64 Edition gives you faster performance, more reliability, and greater flexibility than 32-bit systems. You can run memory-intensive and calculation-intensive applications and processes more efficiently. Whether you’re a technical workstation user or a cutting-edge home PC enthusiast, it provides a secure platform that can run new 64-bit applications, as well as most existing 32-bit applications, on a single PC—while still having all of the benefits of Windows XP Professional Edition.

While there are many benefits of Windows XP Professional x64 Edition, these 10 are at the top of the list.

Premier performance
Windows XP Professional x64 Edition is a robust platform that offers premier performance that is unparalleled in the mainstream 32-bit desktop environment. Sixty-four-bit native applications can deliver more data more quickly, so memory-intensive applications can run more quickly and efficiently. Data in memory is accessed thousands of times faster than it is on a disk drive. Applications can preload substantially more data into virtual memory, allowing rapid access by the 64-bit processor.

Vast memory support
The key difference between 32-bit and 64-bit computing with Windows XP is that the 64-bit version can use more system memory. Windows XP Professional x64 Edition supports up to 128 gigabytes (GB) of RAM and 16 terabytes of virtual memory, so applications can run faster when working with large data sets. Physical memory support will grow in the future as hardware capabilities expand.

Optimized platform and improved collaboration
With Windows XP Professional x64 Edition, you can standardize your mainstream desktop computers with your high-end workstations, increasing performance, improving manageability, and freeing up IT resources. You can also improve information sharing and collaboration by using Microsoft productivity tools across your organization. Add Windows XP Professional x64 Edition systems to existing Windows-based networks and manage them alongside 32-bit systems with the same administrative tools that you already use, making life easier for your IT department.

Increased reliability and security for your most important data
Windows XP Professional x64 Edition is built on the Windows Server 2003 Service Pack 1 (SP1) code-base, and provides optimum security and reliability for business-critical desktop computing. Now you can experience the stability and security of a server product on your PC. Windows XP Professional x64 Edition can help protect you from many types of viruses that try to exploit data. Its improved memory support helps protect your system against malicious attacks, such as memory buffer overruns.

Opportunity for innovation
Most 64-bit computers can manage exponentially more data than 32-bit systems can. With Windows XP Professional x64 Edition you can design, develop, and interact with new applications, games, and tools that weren’t possible with older technologies. Windows XP Professional x64 Edition provides solutions for current and future use. It delivers more memory combined with the ease of use of the established Windows platform.

Greater flexibility
Windows XP Professional x64 Edition gives you a robust platform for the integration of 64-bit and 32-bit applications using the Windows on Windows 64 (WOW64) x86 emulation layer. You can move to 64-bit computing while still maintaining your existing investment in 32-bit software and Windows expertise.

Multiprocessing and multicore processor support
Windows XP Professional x64 Edition is designed to support up to two single or multicore x64 processors for maximum performance and scalability.

Advantages for specialized, technical applications
The performance of 64-bit computing offers advantages in fields such as automobile and airplane design by allowing engineers to create larger, more complex models. Engineers can use simulation software to analyze the effects of airflow, stress, and heat on the materials of a car or airplane, and then study the results to improve overall product design. Likewise, 64-bit computing benefits digital content creators, including three-dimensional (3-D) animators, digital artists, and game developers, who can significantly reduce the time they spend digitally rendering 3-D models. In the areas of scientific and high-performance computing, Windows XP Professional x64 Edition can aid in oil and gas exploration, seismic analysis, computational fluid dynamics, and scientific visualization, among other applications.

Single desktop for technical and business applications
Windows XP Professional x64 Edition provides a single PC for technical and business applications, so you don’t need to maintain one PC for business applications and a separate workstation for high-end technical applications. Most Windows-compatible 32-bit applications run "as is" in a subsystem of Windows XP Professional x64 Edition, with performance comparable to 32-bit Windows. You can take advantage of rich integration capabilities and productivity tools on the Windows platform. Designers can build a model and easily share it with others in your company, copying it into a Microsoft Office Word document for the finance group or adding it to a Microsoft Office PowerPoint slide deck for the marketing team.

Familiar programming model
Developers with 32-bit computing skills will be comfortable and productive in the 64-bit Windows environment, finding the development environments virtually identical. The 64-bit Windows development environment supports the same feature set as 32-bit Windows, including user interface and programming models, networking, security, graphics, multimedia, directory service, Plug and Play, and tools features. Many of the functions have been modified to reflect the computational precision of the platform on which an application is run. The result is programming simplicity and a short learning curve for the developer—writing code for 64-bit Windows is just like writing code for 32-bit Windows.
