区别和好处在32位之间(x86)对64位(x64)窗口景色
每窗口景色的编辑操作系统是可利用的在32位和64位版本(x86 anx x64是微软使用的用语)，现在做出64位OS选择一个广泛可利用的选择。 并且用几乎所有CPU处理器和主板现今是能跑64位OS，它是否提出决策对消费者决定和采摘基于的x64 窗口景色的32位或64位版本 是适当的选择。
微软出版在桌里详述在32位和64位窗口景色之间的主要区别，与记忆可及性主要关连，内存管理的KB946765和改进的安全特点，如如下所示。
| 建筑学 | 窗口景色， 32位版本 | 窗口景色， 64位版本 |
|---|---|---|
| 系统要求 | 1千兆赫(千兆赫) 32位(x86)处理器或64位(x64)处理器， 512 MB RAM |
1千兆赫64位(x64)处理器， 1 GB RAM (被推荐的4 GB) |
| 存储器存取 | 窗口景色的32位版本可能访问4 GB RAM。 | 窗口景色的一个64位版本可能从1 GB RAM访问到超过128 GB RAM。 |
| 存储器存取每编辑 | 窗口景色的所有32位版本可能访问4 GB RAM。 | 窗口景色在家基本- 8 GB RAM 在家窗口景色保险费- 16 GB RAM 窗口景色事务- RAM或更多的128 GB 窗口景色企业- RAM或更多的128 GB 窗口景色最后- RAM或更多的128 GB |
| DEP | 窗口景色的32位版本使用DEP的一个基于软件的版本。 | 窗口景色支持的64位版本硬件支持DEP。 |
| 仁补丁保护(PatchGuard) | 这个特点不是可利用的在窗口景色的32位版本。 | 这个特点是可利用的在窗口景色的64位版本。 仁补丁保护帮助防止一个恶意节目更新窗口景色仁。 这个特点运作在帮助旁边防止仁方式司机扩大或替换其他仁服务。 并且，这个特点帮助防止第三方节目更新(修补)仁的任何部分。 |
| 司机签字 | 未签名的司机也许使用以窗口景色的32位版本。 | 窗口景色的64位版本要求所有设备驱动程序数字式地由开发商签字。 |
| 32位司机支持 | 窗口景色的32位版本支持为窗口景色设计的32位司机。 | 窗口景色的64位版本不支持32位设备驱动程序。 |
| 16位节目支持 | 窗口景色的32位版本支持16位节目，在part。 | 窗口景色的64位版本不支持16位节目。 |
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 have a new computer with Vista 64 bit. I want to go online and access my office computer but it is 32 bit. Is there a way to communicate with the 32 from my 64bit system?
thanks, John

hehehehe, I feel like my computer is “out of place”. I only have Pentium D 2.66Ghz
(has SSE1, SSE2, AND 64-BIT instructions if i remember right) DDR768MB(kingston 256MB & Dynet 512MB) 3PATA HDDw/ a total of 200GB Nvidia MX400 (128MB VRAM) ^_^
hehehehe.,. I’m using windows XP Pro 32-bit, is there any advantage in switching to Windows XP 64-bit? I’m only 16 years old,.,. so sorry for not being an expert ~_~…
but still, I’m guessing there isn’t much since my RAM doesn’t even go more than 1 GB.
anyway, thanks in advance for the answer.

Age of 64-bit has arrived, Age of 32-bit is vanishing!
Soon, no more 32-bit computers will ship… *plays the world?s smallest violin*
Out of the 11 HP laptops listed as “new arrivals” at Best Buy, 9 come with 4GB of memory and 64-bit Vista. Ironically, the other two new-arrival HP systems come with “Windows Vista Business downgraded to XP Pro.”
In other words, you get either XP or 64-bit Vista: 32-bit Vista is not offered standard at all in this list of new arrivals.

In NewEgg?s Top Desktop Sellers List as-of the time of this writing, it also resembles the above pattern. Interestingly, there are 2 “Windows Vista Business downgraded to XP Pro” too!

I just went dual boot 32xp and 64vista ultimate bit as two of my programs are not yet available in 64 bit. Loading smaller 2gb ram mods for 8g’s of ram instead of using 4gb mods to save cost. So far all looks good.

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.?

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.

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.

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.

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.
June 4th, 2008 18:05
Yup, that’s what I’m hoping for.
June 4th, 2008 17:07
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).

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