What is the difference between Win Vista 32-bit and 64-bit?

                  What is the difference between Vista 32-bit and 64-bit. If a 64-bit machine is equipped with 64-bit Vista, can 32-bit applications or games be installed?

best answer:

Windows Vista x64 introduce

For general users, will certainly consider, since the existing 32-bit version of Windows also used well, why should upgrade to 64-bit, and because 32-bit and 64-bit hardware (mainly CPU and motherboard) are not compatible, it may cost a lot of money. So what are the advantages of 64? Is it necessary for a general user to upgrade to a 64-bit system?

Windows Vista x64 Edition is designed to meet the needs of customers who require large amounts of memory and floating point performance in areas such as mechanical design and analysis, 3D animation, video editing and authoring, and scientific computing and high-performance computing applications. demand.

Performance Benefits of Dedicated Technology Applications

64-bit computing performance excels in areas such as automotive or aircraft design because it allows engineers to create larger, more complex models. With such a system, engineers can use simulation software to analyze the effects of airflow, pressure, and heat on automotive or aircraft materials, and then study the results to improve product design. Similarly, with 64-bit computing, digital content creators (including 3D animators, digital artists, and game developers) can greatly reduce the time it takes to render 3D models digitally. In the areas of scientific computing and high performance computing, Windows Vista x64 Edition will help applications such as oil and gas exploration, seismic analysis, computational fluid dynamics, and scientific visualization.

Support for very large memory, using common Windows desktops

For customers who have 32-bit system memory limitations, Windows Vista x64 Edition will be AMD Athlon 64, AMD Opteron, Intel supporting SM64T Xeon and Intel Pentium 4 supporting EM64T are the operating platform. The main difference between 32-bit and 64-bit computing based on Windows XP is that the 64 version can use more system memory. Windows Vista x64 Edition will initially support up to 128 GB of memory and up to 16 TB of virtual memory. In the future, as hardware functions expand, the supported physical memory will increase accordingly. In-memory data is accessed thousands of times faster on disk drives, which greatly increases the performance of applications developed for use with this larger system memory.

Providing a single desktop for technical and business applications

Windows Vista x64 Edition will provide a single desktop for technical and business applications, so technical workstation users do not need to do business applications The program maintains the PC while maintaining a separate workstation for high-end technology applications. Most Windows-compatible 32-bit applications will run "as-is" in the Windows Vista x64 Edition subsystem, which is comparable in performance to 32-bit Windows. Workstation users can take advantage of the rich integration features and efficient tools on the Windows platform. Designers can build a model and easily share it with other people in the company: for a finance group, copy it to a Word document, or for a market group, add it to the PowerPoint slide panel. If you only use 32-bit applications and the data set is no more than 2 GB, you will find that 32-bit Windows Vista is the best desktop system for your application.

Windows Vista x64 Edition systems can be added to existing Windows-based networks and managed with 32-bit systems using the same management tools, making IT work easier. The overhead costs of maintaining and managing both systems are reduced.

The Best Platform for Next-Generation Applications

Developers with 32-bit Windows skills will be able to create next-generation applications for Windows Vista x64 Edition comfortably and efficiently. Developers will find the development environment to be almost identical to the 32-bit Windows development environment; the Microsoft Win64 application programming interface (API) is identical to the Microsoft Win32 API. Existing APIs have been modified as necessary to reflect the accuracy of their operating platform. The result is simplified programming and shortened the learning curve for developers writing 64-bit Windows code, just like writing 32-bit Windows code.

The 64-bit Windows development environment supports the same feature set as 32-bit Windows, including UI and programming models, networking, security, graphics, multimedia, directory services, plug-and-play, and tooling. Many of the features have been modified to reflect the computational accuracy of the application's runtime platform.

Key Features of Windows Vista x64 Edition

Compared to 32-bit Windows, one of our obvious feelings is that the amount of memory support has been improved. 32-bit Windows can support up to 4 GB of system memory, and each processor can use up to 2 GB of dedicated memory; on 64-bit Windows, up to 128 GB of physical memory and 16 TB of virtual memory can be used.
