To support 64-bit platforms such as Intel Xeon, Intel Core 2, AMD Opteron and AMD Athlon 64, Microsoft released 64-bit versions of every edition of Windows Vista except for the Starter edition. These editions can run 32-bit programs by running them within the WOW64 subsystem. Most 32-bit programs can run natively, though applications that rely on device drivers will not run unless those device drivers have been written for 64-bit Windows. Most older hardware does not have the necessary support to get the drivers written.
Other applications may have difficulty as well. For example, the Visual Basic 6 IDE will run natively on 32-bit editions, but will not run at all on 64-bit editions.Some application vendors will only provide full / premium product versions for 64-bit Vista and cut down versions for 32-bit Vista (e.g. Adobe Premiere Elements is 32-bit and the full Adobe Premiere is available for 64-bit Vista - with more capability but at a much higher price).
Various reviewers have reported that the 64-bit editions of Windows Vista outperform their 32-bit counterparts in synthetic benchmarks such as PassMark.For example, in early testing of 64-bit support in Photoshop for Windows, overall performance gains ranged from 8% to 12%. Those who work with extremely large files may realize noticeably greater gains in performance, in some cases as dramatic as ten times the previous speed. This is because 64-bit applications can address larger amounts of memory and thus result in less file swapping — one of the biggest factors that can affect data processing speed.
All 64-bit versions of Microsoft operating systems currently impose a 16 TB limit on address space. Processes created on the 64-bit editions of Windows Vista can have 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB. In terms of physical memory Windows Vista 64-Bit Basic supports up to 8 GB of RAM, Windows Vista 64-Bit Home Premium supports up to 16 GB of RAM, and Windows Vista 64-Bit Business/Enterprise/Ultimate supports up to 128 GB of RAM.
