區別和好處在32位之間(x86)對64位(x64)窗口景色
每窗口景色的編輯操作系統是可利用的在32位和64位版本(x86 anx x64是微軟使用的用語)，現在做出64位OS選擇一個廣泛可利用的選擇。 并且用幾乎所有CPU處理器和主板現今是能跑64位OS，它是否提出決策對消費者決定和採摘基於的x64 窗口景色的32位或64位版本 是適當的選擇。
微軟出版在桌裡詳述在32位和64位窗口景色之間的主要區別，與記憶可及性主要關連，內存管理的KB946765和改進的安全特點，如如下所示。
| 建築學 | 窗口景色， 32位版本 | 窗口景色， 64位版本 |
|---|---|---|

1千兆赫64位(x64)處理器， 1 GB RAM (被推薦的4 GB) |
| 存儲器存取 | 窗口景色的32位版本可能訪問4 GB RAM。 | 窗口景色的一個64位版本可能從1 GB RAM訪問到超過128 GB RAM。 |
| 存儲器存取每編輯 | 窗口景色的所有32位版本可能訪問4 GB RAM。 | 窗口景色在家基本- 4 GB RAM 在家窗口景色保險費- 16 GB RAM 窗口景色事務- RAM或更多的128 GB 窗口景色企業- RAM或更多的128 GB 窗口景色最後- RAM或更多的128 GB |
| DEP | 窗口景色的32位版本使用DEP的一個基於軟件的版本。 | 窗口景色支持的64位版本硬件支持DEP。 |
| 仁補丁保護(PatchGuard) | 這個特點不是可利用的在窗口景色的32位版本。 | 這個特點是可利用的在窗口景色的64位版本。 仁補丁保護幫助防止一個惡意節目更新窗口景色仁。 這個特點運作在幫助旁邊防止仁方式司機擴大或替換其他仁服務。 並且，這個特點幫助防止第三方節目更新(修補)仁的任何部分。 |
| 司機簽字 | 未簽名的司機也許使用以窗口景色的32位版本。 | 窗口景色的64位版本要求所有設備驅動程序數字式地由開發商簽字。 |
| 32位司機支持 | 窗口景色的32位版本支持為窗口景色設計的32位司機。 | 窗口景色的64位版本不支持32位設備驅動程序。 |
| 16位節目支持 | 窗口景色的32位版本支持16位節目，在part。 | 窗口景色的64位版本不支持16位節目。 |
If you value the benefits and advantages of switching and embracing 64-bit Windows Vista, here’s a few considerations to ponder before making the move to install x64 Windows Vista:
- 64-bit device drivers may not be available for one or more devices in the computer.
- Device drivers must be digitally signed.
- 32-bit device drivers are not supported.
- 32-bit programs may not be fully compatible with a 64-bit operating system.
- It may be difficult to locate programs that are written specifically for a 64-bit operating system.
- Not all hardware devices may be compatible with a 64-bit version of Windows Vista.

I hope everyone stops using 32-Bit and starts using 64-Bit operating systems!

Easier said than done. You need to realize that the market itself is with a majority of users wanting CLEAR advantages out of x64 OSes. How’s the prices? How much more necessary for base RAM reqs? And what’s the final point after all that? Roughly most of them don’t see the general need of 128Gb RAM access if they only compute on Web surfing and productivity apps (such as Office) half the time. Coupled with the currently horrible 3rd party support for x64 drivers in PC gaming’s aspect for instance, we can’t really say there’s any chance in seeing any accelerated adoption of x64 OS until issues like that gets sorted out in due time. Different thing if we’re talking about Apple’s Mac OS X (read: I’m NOT an Apple fanboi).

Yup, that’s what I’m hoping for.

After reading a few of these articles on “64-bit Vista vs. 32-bit” I’ve decided to go with 32-bit. It seems 64 bit OS won’t be fully utilized for at least a few more years in consumer PCs. Unless you’re planning to edit digital video/etc. you won’t experience the full benefits of the 64 bit.

FDS, I’ll tell you one thing.
With 64-Bit, I can use over 4GB of RAM, but with 32-Bit, I am limited. RAM is so cheap these days that I bought 20GB (20 sticks of 1GB DDR2) for $2 each. Ten of them are made by OCZ and the other ten are made by Crucial / Micron.

Technically…
…all 64-bit versions of Microsoft operating systems currently impose a 16 TB limit on address space and allow no more than 128 GB of physical memory due to the impracticality of having 16 TB of RAM. Processes created on Windows Vista x64 Edition are allotted 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB.

I would say that unless you have no substitute for 32-bit apps that don’t work (e.g. need for business), go 64-bit
I would guess that when things like Adobe CS4 64-bit (available only in 32-bit for Mac for that guy who mentioned OSX) and Office 13, etc. even if there is a 32-bit version and all, you would be slowed down a lot with having lower RAM. Remember that if you have just a 512 Graphics RAM, your user RAM will only be like 3.2 because of all the other devices. And for those SLI gamers…you can cut the user RAM easily under 2.5GB for 32-bit systems.
You have to also consider SuperFetch.
Vista uses extra RAM to store commonly used files in a new activity known as “disk caching” (SuperFetch). The computer uses artificial intelligence to determine which files will be used most and copies it to RAM (where it is much faster than accessing your hard disk). This includes components of the programs you use on a regular basis. When you need more RAM for programs you launch, etc. the computer purges the “least likely used” files from RAM to make room for the new program. That’s why if you look at the performance monitor, Vista always has near zero “free” RAM. So in theory, the more RAM (for disk cache) you have, the faster your computer will operate. This can also be augmented (to a lesser effect) with a flash drive/card with a technology called ReadyBoost. Just stick it in and select “Speed up my system” and leave it there. Google “AnandTech ReadyBoost Performance” for basic test examples.
High RAM will be especially helpful for those people who like to leave all their windows open and use Vista’s “S3 sleep mode” (2 watts) so they can resume where they left off almost immediately after they turn their computers on.

If this is any indication that 64-bit is the wave of the future and 32-bit will be “obsolete”…
“There appears to be a shift taking place in the PC industry: the move from 32-bit to 64-bit PCs.
We’ve been tracking the change by looking at the percentage of 64-bit PCs connecting to Windows Update, and have seen a dramatic increase in recent months. The installed base of 64-bit Windows Vista PCs, as a percentage of all Windows Vista systems, has more than tripled in the U.S. in the last three months, while worldwide adoption has more than doubled during the same period. Another view shows that 20% of new Windows Vista PCs in the U.S. connecting to Windows Update in June were 64-bit PCs, up from just 3% in March. Put more simply, usage of 64-bit Windows Vista is growing much more rapidly than 32-bit. Based on current trends, this growth will accelerate as the retail channel shifts to supplying a rapidly increasing assortment of 64-bit desktops and laptops.”
